General Features
The DUO 2400 Pack has been designed to produce the most compact, versatile and
easy to use flash source available today. Features include:
z
Two independent Channels, each having a Quad style head socket, ‘FLASH’
Variator, Modelling ‘LAMP’ Variator and Modelling ‘LAMP’ Control switch.
z
An ‘ISOLATE’ mode which allows each of the Channels to be independently
controlled with up to half the total flash capacity of the Pack.
z
A ‘COMBINE’ mode which provides the total flash capacity of the Pack from
EITHER or BOTH sockets with a single set of controls.
z
Modelling ‘LAMP’ Variator and Modelling ‘LAMP’ Controls independent of Flash
controls.
z
‘POWER’ display of the selected MAXIMUM flash capacity of the Pack and a
visible ‘READY’ indication.
z
Built in, sensitive ‘SLAVE’ Photocell with ON/OFF switch.
z
AUDIBLE ‘READY’ Sounder with ON/OFF switch to give audible indication of
when the Pack is ready to fire.
z
A built in fan automatically switches in to cool the unit during periods of heavy use.
z
Overheat protection which protects the unit in the event of extended periods of
continuous flashing and also in the unlikely event of failure of the cooling fan.
z
EMC (Electro-Magnetic Compatibility) filters fitted.
Power Supply Connection
z
The Packs are designed to operate on an alternating current (AC) supply of 200 to
253 Volts, 50 Hz. The Packs must NEVER be connected to any direct current
(DC) supply.
z
The Packs conform to current standards which require connection to a properly
grounded power supply. The 3 core power cord supplied with each Pack is colour
coded as follows:
Live
(L):
Brown
Neutral
(N):
Blue
Earth
(E):
Green/Yellow
z
If a moulded plug is not fitted it is essential that all 3 wires are connected to the
correct plug pins in accordance with the above colour code and that the cable is
securely clamped in the supply plug.
AC Power Switch
z
The AC Power switch connects power to both the flash and modelling circuits.
The switch is illuminated green when ‘ON’.
z
ALWAYS switch ‘OFF’ the unit before plugging or unplugging Flash Heads,
changing fuses or modelling lamps.
Circuit Protection
z
Protection of the Modelling circuitry is by means of a 20mm fuse mounted on the
control panel of the Pack. The fuse is rated at 15 Amp (T) and should never be
replaced with a fuse of a different type or rating.
