Brown Line Power Supplies
General Power Supply Instructions
For maximum equipment life and for safe, dependable operation of power supplies we advise you
to follow these general rules.
Unpack equipment carefully. Examine all packing material. Should you notice any breakage or
defect, notify the dealer and carrier (if shipped to you) immediately. Then please read all instructions
before assembling your flash system in order to avoid damage to your equipment or injury to yourself.
Before doing anything with the power supply make sure that the Model and Power switches are in
the off position.
Connect light head cable(s) to the Light Unit Outlet(s) on the power supply, selecting the
appropriate outlets for the desired power level.
All Brown Line light units can handle at least 400 watt-seconds, and specific units are designed for
a maximum of 1200 or 1600 watt-seconds. For power supplies that can produce more than 400Ws
of power, you must be very careful that the flash tube you are using in your light unit can handle all
the available power. Never subject a flash tube to more watt-seconds than it is designed to handle. If
you are not sure that your flash tube can handle the power provided by the set-up you are using,
check the technical specifications of the light unit in addition to the Power Distribution Chart on the side of your power supply.
We recommend that you purchase at least one light unit that will accept the full output of the
power supply.
To connect light units, align the light unit plug with the power supply outlet and apply even
pressure while pushing. Black colored light unit connectors are of the "quick release" type that only
require pushing the connector firmly until it is fully seated. Silvery colored light unit connectors must
be threaded until they are fully seated. Both types prevent accidental cable removal. Make sure all
light unit cables are firmly seated to prevent connector damage. Tape all cables to the floor and keep
them out of the pathways to prevent accidents.
Never install light units while the power supply is turned on. Never insert or remove flash tubes
while the light unit is connected to the power supply. Be sure flash tubes are fully seated into light
unit sockets. (Read instructions in the Light Units section of this manual for more information on light
unit assembly and operation.)
Speedotron power supplies are equipped with arc-protected outlets. However, as with any
electrical equipment, arc-over (an electrical discharge between two physically disconnected electrical terminals)
is a possibility. When light cables, flash tubes or power cords are improperly seated, arc-over may
occur. Also, if your light unit or power supply malfunctions, or the power cord or the internal wiring in
the studio is improperly terminated or defective, there is a chance of arc-over when connecting or
disconnecting light units. Severe power supply damage and operator injury may result if arc-over
occurs. That is why in spite of the arc-protection feature of Speedotron power supplies, you should
always make sure your Model and Power switches are off when disconnecting or connecting light units.
Plug sync extension into Sync socket and connect the other end to a PC cord designed for your camera
or lens. The sync extension supplied with the power supply accepts the standard AC twin-blade type
sync connector. A standard AC to PC sync cord will be required to connect the camera to the
power supply's sync extension.
A slave tripper (Speedotron #23510) may be installed in the Sync socket (in place of the sync
extension) to fire the power supply. If the power supply fails to flash when exposed to another light source
with the slave installed in the Sync socket, remove the slave, rotate it 180° and reinstall it in the socket.
Connect AC power cord into Power Input on power supply. A 3-terminal ground power plug is
utilized on Brown Line power supplies. For maximum performance and safety, it is strongly suggested that
the 3-terminal cord supplied with the power supply be properly utilized and properly terminated at
the main source of incoming power. Always use a three-wire ground power cord and a properly
grounded wall outlet with all Speedotron power supplies. Failure to do so may cause the power supply to
intermittently misfire. We do not recommend using an adapter and installing into a 2-blade outlet.
Once the light units are properly assembled and installed, the power cord is installed and the
sync extension is connected, turn the Power switch on.
Now refer to the Operating Instructions section of this manual for information regarding the
proper use of your particular power supply.
Never attempt to make repairs to your Speedotron equipment. All electronic flash systems operate
on high voltage and high power. It is very dangerous to open a power supply.
In order to maximize the life of the power supply it is recommended that the capacitors be
"formed" when a pack is not in use for 30 days or more. All that is required of the user is to turn on the
power supply for about 10 to 20 minutes each month. This simple procedure prevents premature failure
by maintaining the "elasticity" of the capacitors.
General Description of Controls '04s
Power - turns power supply on and off (flashes light units when turning off).
Model - turns model lamp(s) on and off.
Symmetrical/Asymmetrical - controls power distribution. In the symmetrical position, power is
split equally between all lights. In the asymmetrical position, power is distributed unequally and
modeling lamp brightness on light units in outlets 3 and 4 is reduced.
Full/Half (on D604) or Full/Half/1/4 (on D1204 and D1604) - controls the total amount of
power delivered to light unit outlets.
Ready/Push to Flash - combination ready light and test flash button. Illuminates in green to
indicate when power supply has recycled to 85%. Pressing the button when illuminated triggers the flash
for testing or open flash applications.
Audible Recycle - controls audible ready tone (on/off).
Power On - green LED illuminates when power switch is turned on.
Hi-Temp - red LED lights, alarm tone sounds, when internal heat becomes excessive.
Sync - socket for sync extension or slave.
Push to Reset - resets circuit breaker. Circuit breaker disables power supply in case of malfunction.
Power Input - socket for AC power cord.
Light Unit Outlets (4) - sockets for connecting from one to four light units to power supply.
Operating Instructions '04s
Operation of the D604, D1204 and D1604 power supplies is simple and straight forward. This
sequence of operation is suggested for maximum life and dependability.
Make sure that the Model and Power switches are in the off position and the Push to Reset button
is fully depressed into its socket. Connect light head cable(s) to the Light Unit Outlet(s) on the
power supply. The outlets are wired in parallel so it does not matter in what sequence light head cables
are connected.
Never connect or disconnect light units while power is on. Do not insert or remove flash tubes
while power is on. Your Brown Line power supply is equipped with arc-protection, but should your light
unit or power supply malfunction, or the power cord, or even the internal wiring in the studio be
improperly terminated or defective, the chance of arc-over when connecting or disconnecting light units
is greatly increased. Severe power supply damage and operator injury may result if arc-over
occurs when light units are being disconnected or connected. To prevent this, you should always turn
the power supply off when disconnecting or connecting light heads.
Never subject a flash tube to more watt-seconds than it is designed to handle.
MW3 and M90 series (non-"Q") light units have a maximum rating of 400Ws, while "Q" versions
are rated at 1200Ws. M11 light units are rated at 1200Ws (the new MW9H flash tubes supplied with
M11 light units handle up to 1200Ws; MW9M flash tubes have a maximum capacity of 1000Ws.)
and M11Q light units are rated at 2400Ws. We strongly recommend that at least one light unit in
your system is capable of handling the maximum output of your power supply. If you are not sure if
your flash tube and light unit can handle the power provided by the set up you are using, check the technical specifications of the light unit and the Power Distribution Chart on the side of your power supply.
Connect AC power cord into Power Input on power supply, then plug into a properly
grounded outlet. Use proper 3-conductor grounded cord for operator safety and to reduce self-firing
and misfiring caused by static electricity. Set Full/Half/1/4 switch as desired (Full/Half switch on D604).
This switch reduces the total output of the power supply. Do not switch the Full/Half/1/4 switch until
ready light is illuminated. Failure to follow this procedure may result in damage to the switch.
Plug sync connector into Sync socket and connect the other end to PC cord for camera. Once
the camera is connected, tripping the shutter will automatically trigger the flash.
A slave tripper (Speedotron #23510), may be inserted into the Sync socket in place of the PC cord.
In this mode of operation, the slave will activate the power supply when it senses a bright flash of
light from another light source. If the power supply fails to flash when exposed to another light
source with the slave installed in the sync socket, it may be necessary to remove the slave, rotate it 180°
and reinstall it into the Sync socket.
Turn on Power and Model switches. Wait until the green Ready/Push to Flash illuminates and press
to check if the unit is operational. The light unit(s) should flash instantly when this button is pressed.
If you wish to check the function of each individual light unit, we recommend that you turn off
the Model switch and hold your hand in front of (not inside) the light unit to be tested. When you fire
the unit you will feel the heat of the flash. This method is suggested because it is often difficult to
determine by sight if one of the lights has failed to flash.
The D604, D1204 and D1604 power supplies are equipped with an audible ready signal (may
be turned off) and high temperature alarm. A short audible tone along with a green Ready/Push to
Flash light indicates that the power supply has recycled to 85 percent (ANSI standard). For very
critical exposures, waiting several seconds after the green Ready/Push to Flash light illuminates will
ensure that the power supply is at 100 percent power. If the beep should prove distracting, depress
the Audible Recycle switch to eliminate this short tone. The green Ready/Push to Flash light will
still continue to illuminate.
Prolonged rapid flashing or storage in a high temperature environment (like the trunk of a car)
or extended use in extremely warm environments may eventually produce enough heat to set off
a steady alarm tone and red Hi-Temp LED indicator. The power supply should be turned off at
the Power switch because continued use may cause severe damage. When the power supply has
sufficiently cooled, normal operation may be resumed. (If the power supply is not turned off, the
alarm will not clear.)
When the power supply has been exposed to extreme cold weather for an extended period of time,
it is suggested that the unit be allowed to warm up to room temperature before connecting it to an
AC power line.
When disassembling the system, turn off Power and Model switches first. When the Power switch
is turned off, the power supply will discharge by flashing all light units. Placing the Full/Half/1/4
switch into the full position before turning off Power will ensure that all capacitors are discharged. If
the power supply should be inadvertently switched off at a lower power setting, DO NOT
immediately switch to full power! Damage to the switch may result. Wait at least 10 seconds before operating
the Full/Half/1/4 switch. Unplug the power cord and disconnect the light head cable(s).
Power Distribution Tables '04s
On the side of the D604, D1204 and D1604 power supplies there is a Power Distribution Table
based on the full power setting. These tables should be used as guides for determining various
lighting possibilities, guide numbers and exposures when using consistent flash tubes and reflectors.
When different flash tubes and/or reflectors are used actual light output will vary, producing as much as a
full f/stop discrepancy with the table.
Brown Line '04 power supplies, feature symmetrical and asymmetrical operation. Symmetrical
output means all light units share equal output. To determine power levels, divide the maximum output by
the number of light units to be used. In asymmetrical mode, outlets 1 and 2 receive a greater portion
of the total output than outlets 3 and 4. (For specific power distribution refer to the charts below for
the number and configuration of the lights to be used.)
D604 Power Distribution Table
One light: Symmetrical mode in any outlet, will receive 600Ws.
Asymmetrical mode in outlets 1 or 2, will receive 600Ws; when using outlets 3 or 4 output is 450Ws.
Two lights: Symmetrical mode, all outlets share an equal amount of power. Two lights each receive 300Ws (600Ws divided by 2).

Operating Instructions D402 & D802B
Operation of Brown Line power supplies is simple and straight forward. It is suggested that this
sequence of operation be utilized for maximum life and dependability.
Make sure that the Model and Power switches are in the off position and the Push to Reset buttons
are fully depressed into their sockets. Connect light head cable(s) to the Light Unit Outlet(s) on the
power supply. The outlets are wired in parallel so it does not matter in what sequence light head cables
are connected.
Never connect or disconnect light units while power is on. Do not insert or remove flash tubes
while power is on. Your Brown Line power supply is equipped with arc-protection, but should your light
unit or power supply malfunction, or the power cord, or even the internal wiring in the studio be
improperly terminated or defective, the chance of arc-over when connecting or disconnecting light units
is greatly increased. Severe power supply damage and operator injury may result if arc-over occurs
when light units are being disconnected or connected. To prevent this, you should always turn the
power supply off when disconnecting or connecting light heads.
Never subject a flash tube to more watt-seconds than it is designed to handle. MW3 and M90
series (non-"Q") light units have a maximum rating of 400Ws, while "Q" versions are rated at 1200Ws.
M11 light units are rated at 1200Ws (with new MW9H flashtube) and M11Q light units are rated at
2400Ws. We strongly recommend that at least one light unit in your system is capable of handling the
maximum output of your power supply. If you are not sure if your flash tube and light unit can handle
the power provided by the set up you are using, check the technical specifications of the light unit and the Power Distribution
Chart on the side of your power supply.
Connect AC power cord into Power Input on power supply, then plug into a properly grounded
outlet. Use proper 3-conductor grounded cord for operator safety and to reduce self-firing caused by
static electricity. Set Full/Half switch as desired. This switch reduces the total output of the power supply.
The difference between the "full" and "half" settings is one f-stop. After flashing, do not switch the
Full/Half switch until ready light is illuminated, or until at least ten seconds after turning off unit. Failure
to follow this procedure may result in damage to the switch.
Plug sync connector into Sync socket and connect the other end to PC cord for camera. Once
the camera is connected, tripping the shutter will automatically trigger the flash.
A slave tripper (Speedotron #23510), may be inserted into the Sync socket in place of the PC cord.
In this mode of operation, the slave will activate the power supply when it senses a bright flash of
light from another light source. If the power supply fails to flash when exposed to another light source
with the slave installed in the sync socket, it may be necessary to remove the slave, rotate it 180° and
reinstall it into the Sync socket.
Turn on Power and Model switches. Wait until the Ready/Push to Flash illuminates and press
the button to check if the unit is operational. The light unit(s) should flash instantly when this button
is pressed. If you wish to check the function of each individual light unit, we recommend that you turn
off the Model switch and hold your hand in front of (not inside) the light unit to be tested. When you
fire the unit you will feel the heat of the flash. This method is suggested because it is often difficult
to determine by sight if one of the lights has failed to flash.
When disassembling the system or changing the position of a light unit connector in any outlet, it is
a good habit to set the Full/Half switch to full first, then turn off Model and Power switches prior
to disconnecting light units. If this procedure is not followed, allow 10 seconds between turning
the Power switch off and adjusting the Full/Half switch.
DO NOT immediately switch to full power! Damage to the switch may result.
The D402 and D802B power supplies will flash their light units when turned off. Placing the
Full/Half switch on the D402 and D802B into the full position before turning off Power will ensure that
all capacitors are discharged.
Power Distribution Tables D402 & D802B
On the side of the D402 and D802B power supplies, there is a Power Distribution Table based on
the full power setting. These tables should be used as guides for determining various lighting
possibilities, guide numbers and exposures when using consistent flash tubes and reflectors. When different
flash tubes and/or reflectors are used actual light output will vary producing as much as a full f/stop
discrepancy with the table.
The '02 Series feature symmetrical and asymmetrical operation. Symmetrical output means all
light units share equal output. To determine power levels, divide the total watt-seconds by the number
of light units to be used. In asymmetrical mode, outlets 1 and 2 receive a greater portion of the
total output than outlets 3 and 4. (For specific power distribution refer to the charts below for the
number and configuration of the lights to be used.)
D402 Power Distribution Table
One light: Symmetrical mode in any outlet, will receive 400Ws.
Asymmetrical mode in outlets 1 or 2, will receive 400Ws; when using outlets 3 or 4 output is 300Ws.
Two lights: Symmetrical mode, all outlets share an equal amount of power. Two lights each receive 200Ws (400Ws divided by 2).
Asymmetrical mode
Combination 1: one light in outlet 1 or 2 receives 200Ws; the second light in outlet 3 or 4 receives 100Ws.
Combination 2: in outlets 1 and 2 receive 200Ws each.

Operating Instructions D202
Make sure that the Model and Power switches are in the off position and the Push to Reset button
is fully depressed into its socket. Connect light head cable(s) to the Light Unit Outlet(s) on the
power supply. The outlets are wired in parallel so it does not matter in what sequence light head cables
are connected.
Never connect or disconnect light units while power is on. Do not insert or remove flash tubes
while power is on. Your Brown Line power supply is equipped with arc-protection, but should your light
unit or power supply malfunction, or the power cord, or even the internal wiring in the studio be
improperly terminated or defective, the chance of arc-over when connecting or disconnecting light units
is greatly increased. Severe power supply damage and operator injury may result if arc-over occurs
when light units are being disconnected or connected. To prevent this, you should always turn the
power supply off when disconnecting or connecting light heads.
The D202 is fully compatible with all Speedotron Brown Line light units and flash tubes.
Connect power supply cord into a 3-wire grounded AC outlet. This reduces misfires and
self-firing caused by static electricity.
Plug sync connector into Sync socket and connect the other end to PC cord for camera. Once
the camera is connected, tripping the shutter will automatically trigger the flash.
A slave tripper (Speedotron #23510), may be inserted into the Sync socket in place of the PC cord.
In this mode of operation, the slave will activate the power supply when it senses a bright flash of
light from another light source. If the power supply fails to flash when exposed to another light source
with the slave installed in the sync socket, it may be necessary to remove the slave, rotate it 180° and
reinstall it into the Sync socket.
Turn on Power and Model switches. Wait until the amber Ready/Push to Flash illuminates and
press the button to check if the unit is operational. The light unit(s) should flash instantly when this button
is pressed. If you wish to check the function of each individual light unit, we recommend that you turn
off the Model switch and hold your hand in front of (not inside) the light unit to be tested. When you
fire the unit you will feel the heat of the flash. This method is suggested because it is often difficult
to determine by sight if one of the lights has failed to flash.
The D202 has symmetrical and asymmetrical power distribution. The two light units are connected
in parallel when the symmetrical/asymmetrical switch is in the symmetrical position. With the switch
in the asymmetrical position power will be distributed as shown by the power distribution table on
the next page or on the side of the power pack.

Power Distribution Table D202
On the side of the D202 power supply, there is a Power Distribution Table based on the full
power setting. This table should be used as a guide for determining various lighting possibilities,
guide numbers and exposures when using consistent flash tubes and reflectors. When different flash
tubes and/or reflectors are used actual light output will vary producing as much as a full f/stop
discrepancy with the table.
The '02 Series feature symmetrical and asymmetrical operation. Symmetrical output means all
light units share equal output. To determine power levels, divide the total watt-seconds by the number
of light units to be used. In asymmetrical mode, outlet 1 receives a greater portion of the total
output than outlet 2. (For specific power distribution refer to the charts below for the number and
configuration of the lights to be used.)
D202 Power Distribution Table
One light: Symmetrical mode in any outlet, will receive 200Ws.
Asymmetrical mode: outlet 1 will receive 200Ws; outlet 2 outputs 150Ws.
Two lights: Symmetrical mode, both outlets share an equal amount of power. Two lights each receive 100Ws (200Ws divided by 2).
Asymmetrical mode: light in outlet 1 receives 100Ws; the light in outlet 2 receives 50Ws.
Brown Line Light Units
General Instructions and Information
The Speedotron Brown Line light units described here may be used with any Speedotron Brown
Line power supply using the five-pin MS outlet. All light units are supplied with a 20' wired-in cable.
Unpack and examine all equipment carefully. Should you notice any breakage or defect, notify
your dealer (and the carrier if it was shipped to you) immediately. The flash tube(s) and model lamp(s)
are packed in their original cartons. This affords sufficient protection and reduces the incidence of
breakage during shipping. Make sure all packing materials are removed before using. This includes the
pipe cleaners (used as packing material) inside some flash tubes.
Install flash tubes first. Always handle lamps and flash tubes with care. Because they can break if
put under stress, handle them cautiously. Don't touch glass surfaces with your bare hands. If your
fingers come in contact with the glass of the model lamp, wipe off carefully with alcohol. When removing
or replacing lamps and tubes, always disconnect light units from power supply. Allow lamps to
cool before handling. For instructions on how to insert model lamps into specific units, see the unit
descriptions on the following pages.
Flash tubes must be inserted into the sockets all the way. Flash tube pins must align with the flash
tube socket to be inserted. Apply gentle pressure. A slight rocking motion may be necessary when
installing larger flash tubes. New flash tubes and sockets fit very tightly. Be sure all flash tubes and model
lamps are fully seated into light unit sockets.
It is important to observe the maximum watt-seconds rating of these light units. Never subject a
flash tube to more watt-seconds than it is designed to handle. MW3 and M90 series (non-"Q") light
units have a maximum rating of 400Ws, while "Q" versions are rated at 1200Ws. M11 light units are rated
at 1200Ws (the newer MW9H flash tubes supplied with M11 light units handle up to 1200Ws;
MW9M flash tubes have a maximum capacity of 1000Ws.) and M11Q light units are rated at 2400Ws.
We strongly recommend that at least one light unit in your system should be capable of handling
the maximum output of your power supply. If you are not sure that the flash tube in your light unit
can handle the power provided by the set up you are using, check the following pages and the
Power Distribution Chart on the side of your power supply. Failure to observe this precaution could
drastically shorten the life of your flash tubes.
Connect light cable(s) to the Light Unit Outlet(s) on the power supply. Never connect or
disconnect light units while Power is on. Do not insert or remove flash tubes or model lamps while Power is on.
To connect light units, align the light unit plug with the power supply outlet and apply even
pressure while pushing. Black colored light unit connectors are of the "quick release" type that only
require pushing the connector firmly until it is fully seated. Silvery colored light unit connectors must
be threaded until they are fully seated. Both types prevent accidental cable removal. Make sure all
light unit cables are firmly seated to prevent connector damage. Tape all cables to the floor and keep
them out of the pathways to prevent accidents.
Speedotron power supplies are equipped with arc-protected outlets. However, as with any
electrical equipment, arc-over (an electrical discharge between two physically disconnected electrical terminals)
is a possibility. When light cables or flash tubes are improperly seated, arc-over may occur. Also, if
your light unit or power supply malfunctions, or the power cord or the internal wiring in the studio
is improperly terminated or defective, there is a chance of arc-over when connecting or
disconnecting light units. Severe power supply damage and operator injury may result if arc-over occurs. That is
why, in spite of the arc-protection feature of Speedotron units, you should always make sure Power is
off when connecting or disconnecting light units.
All Brown Line light units fit on top of 5/8" light stands. MW3U and MW3UCC accept umbrellas
with shafts up to 3/8". MW3R and MW3RCC light units include an adaptor to fit onto 3/8" light stands.
Turn on power supply, wait for Ready light, then press Push to Flash button to verify proper
operation. The model lamp may be turned on or off by the switch located on the top of the light unit
assembly (insure that the Model switch at power supply is on).
For maximum performance and life, the model lamp should be used only when necessary and
turned off after initial set-up or focusing is done. Although convection cooling is more than ample for
normal usage, turning off the model lamp will eliminate heat and enable the light unit to run cooler,
extending the life of all components.
After extended use or after transporting your system, inspect flash tubes for cracks and any
unusual darkening (arc-over) around the tube sockets. If cracks or darkening are noted the flash tube is,
most likely, near the end of its duty cycle. Cracked tubes will probably misfire. The normal duty cycle
is 100,000 flashes for the majority of Speedotron Brown Line flash tubes.
Be sure replacement flash tubes are designed for the watt-second output requirements of
Speedotron light units. Applying too much power severely shortens the life of flash tubes, may cause fine cracks
to develop in the tube that may cause tube failure or, in the most extreme case, may cause the tube
to shatter. For this reason, we suggest you always use Speedotron flash tubes and model lamps to
insure safe and dependable operation.

General Maintenance and Care
All Speedotron Brown Line equipment is ruggedly built. Nevertheless, it should be treated with
the same care given to other pieces of quality photographic equipment. To protect the user, all
Speedotron equipment is designed to be safe when used in accordance with instructions. To assure the
maximum in safe, dependable service, the following guidelines should be carefully observed.
· Avoid kinking or pulling cables. Disconnect cables by pulling on the plug only. Never pull plugs
out by the cable. Light cables as well as sync cords and AC power cords should be occasionally
checked for wear, cracks, separation between cable and plug, and for indications of arc-over.
· Do not wrap the light unit cables around the light units. Coiling cables tightly stresses the
internal wires and may lead to premature cable failure. If possible, keep the coil diameter at least 10 inches.
· If a cable becomes frayed, the insulation damaged, or the connectors bent or broken, have
them repaired immediately.
· Keep all connectors, plugs and sockets free of dust, moisture and corrosion.
· Do not connect or disconnect light units or insert or remove flash tubes while the power supply
is on.
· When using your equipment, be sure all cable, sync, power and flash tube connections are
completely and properly installed.
· Do not attempt to make repairs to your Speedotron equipment yourself. It is very dangerous,
and will void your warranty. Consult your dealer regarding authorized service in your area, or return
the equipment to Speedotron.
· When you are not using your equipment, it is recommended that you store it in a dry place.
Equipment should be charged up and flashed a few times at least once a month. This will keep your
equipment in top working condition for many years.
· With your light unit disconnected, occasionally clean the interior surface of the reflector.
Carefully remove the flash tube, and clean the glass cover. Only in this way will you conserve a consistent
color temperature and light output. Dirt and dust deposits on the tube and reflector act like a filter to
alter color.
· Never handle the quartz halogen model lamps with your bare hands. Use tissue or packing
materials when installing and removing. The natural oils from your skin may cause the glass surface to
heat unevenly and cause early failure. When removing these lamps allow sufficient cooling time
before touching.
· To extend their life, the model lamp circuit should be turned off after set-up and focusing.
Trouble-shooting
System will not work at all; no flash.
Check that sync cable, AC power cord and light unit cables are firmly and properly attached. Check
that the flash tube is firmly seated. Check that Power switch is on.
With metal camera bodies, you may be required to polarize the camera sync cable and the
power supply sync extension in order to avoid possible misfires resulting from a build-up of static
electricity. This is done by touching any unpainted metal part of the power supply with the unpainted part of
the camera, or better still, with the outer shell or the grounded part of the sync cable with all sync
cords attached. If the unit flashes, the plug on the sync cable should be reversed and then marked for
future reference. Test fire the camera after reversing the sync extension cable (PC to power supply). If the
unit still does not fire, reverse the PC to camera connection and try again. The trigger current is very
low and is measured in microamperes, so it is impossible to even feel any shock when touching
these contacts.
Occasional failure of all light units to flash.
Check sync cable and light unit cable connections. Make sure that the Ready indicator is
illuminated before attempting to fire unit.
Occasional failure of one light unit only.
Check light unit cable connection. Inspect the cable. Check flash tube. Make sure that the
Ready/Push to Flash indicator is illuminated before attempting to fire unit.
Reduced light output.
Check to see if Full/Half/Low or Full/Half/1/4 switch is in right position. Check flash tube; check
power supply by comparing to similar pack with same light units if possible.
Flash tube glows after firing (afterglow); will not flash again until glow is gone.
If confined to one light unit, check flash tube by substitution. If it continues or all heads
afterglow, power supply is at fault. If this is the case, turn power supply off immediately! Power supply
needs repair.
Full/Half/Low or Full/Half/1/4 switch has no effect on recycle time or light output.
Power supply needs repair.
Circuit breaker on power supply pops.
Check that all cables on power supply and light units are properly connected. Also check for
afterglow. If a circuit breaker blows, it is an indication that something is wrong. Normal operation will not
blow circuit breakers.
Circuit breaker or fuse in studio blows.
Be sure AC line is rated for a minimum of 10 amperes and that high amperage electrical equipment is not operating on the same AC line.
Important: When checking power supplies, light units and cables, be sure that Power is off. Look
for blackened, discolored or burned pins and sockets. If a Light Unit Outlet on the power supply is
burned, blackened or discolored, it must be replaced before it is used. It could damage light units that
are connected to it. Check that cables are not loose or frayed.
Guide Numbers
Guide numbers provide a starting point in calculating the proper exposure for pictures taken
with flash. A guide number is a constant numerical value (for a given film speed/ISO) determined by
multiplying the light source-to-subject distance by the f-stop in use on the lens. Consequently, dividing
a given (known) guide number by the light source-to-subject distance will yield the proper f-stop.
For example, if the given guide number is 110 and the light source to subject distance is 10 feet, the
f-stop required for proper exposure is f/11.
The formula is as follows:
guide number = G, G = D x F
light source-to-subject distance = D, D = G/F
f-stop = F, F = G/D
Important note: Guide number values provide a general starting point for exposure determination
and vary depending on a myriad of factors such as power supply differences, surrounding area
reflectance, flash tube differences, etc. In some instances such as extreme close-up and macro applications
guide numbers will not provide accurate exposure information. All guide numbers are approximations
and we recommend that test shots be produced to insure exposure accuracy.
The guide numbers bellow are based on exposure from one light only, on axis with an exposure
index of ISO 100 in feet. The information supplied in the chart bellow is most accurate for use in small,
light colored rooms. For large or dark colored rooms it may be necessary to open the lens 1/2 f-stop.
For rooms which are both large and dark colored it may be necessary to open up as much as one full
f-stop.

Flash Duration
Flash duration of a Speedotron Brown Line system will vary with the type of flash tube, the amount
of power outputted and the number of light units connected to the power supply. For example, a
D402 system with two M90 light units and two MW3R light units will have four MW3-1 flash tubes and
a 400Ws power supply. When set to full power each flash tube will output 100 Ws with a flash
duration of 1/1500 second.

Flash duration is measured from 1/2 peak light output to 1/2 light peak output. Light will continue
to be produced for about five times the flash duration but will add little to the exposure. This will
not affect action stopping abilities for most normal contrast subjects.
