General Features

The DUO 4800 Pack has been designed to produce the most compact, powerful,
versatile and easy to use flash source available today. Features include:
Two independent Channels, each having a Quad style head socket, 'FLASH'
Variator, Modelling 'LAMP' Variator and Modelling 'LAMP' Control switch.
An 'ISOLATE' mode which provides the two independently controlled Channels
with half the total flash capacity of the Pack each.
A 'COMBINE' mode which provides the total flash capacity of the Pack available
from the channel A socket, or half the total pack power available from both
channels, with a common set of controls.
Modelling 'LAMP' Variator and Modelling 'LAMP' Controls independent of Flash
controls.
Digital 'POWER' display of the selected total Pack flash capacity and a visible
'READY' indication.
Built in, sensitive 'SLAVE' Photocell with ON/OFF switch.
AUDIBLE 'READY' Sounder with ON/OFF switch to give audible indication of
when the Pack is ready to fire.
A built in fan which cools the unit continuously as long as the mains is supplied.
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.
EMC (Electro-Magnetic Compatibility) filters fitted.

Power Supply Connection

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.
The Packs conform to current standards which require connection to a properly
grounded power supply. The 3 core power cord supplied with each Pack will be
colour coded as follows:
Live (L):
Neutral (N):
Earth (E):
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

The AC Power switch connects power to both the flash and modelling circuits.
The switch is illuminated green when 'ON'.
ALWAYS switch 'OFF' the unit before plugging or unplugging Flash Heads,
changing fuses or modelling lamps.

Circuit Protection

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.
