Introduction
The is a four channel integrated desk/dimmer unit with both normal and audio chase, flash
facility and full mastering over all channels. It has been designed for lower budget applications where
portability and ease of operation are prime considerations. When used as a stand-alone dimmer, the
features:
•Individual channel level control faders;
•Full mastering over all channels;
•Four channel chaser with level and speed control;
•Audio chase facility;
•Flash buttons on all channels;
•Circuit breaker over-current protection;
•Soft turn on (protects bulbs and wiring);
•Overvoltage limit (regulates output against mains voltage variations);
•Sloping front panel;
•Solid construction two-piece steel chassis and base;
•2.4kW total load;
•Stylish appearance;
•Low electrical and audible noise;
•End cheeks for front panel protection;
•Hand insert in base for portability;
•Internal microphone.
The will drive loads of up to 2400 Watts per channel, although total loading is limited to 2400
Watts (which is the maximum power available from any standard 240V AC GPO outlet).
Each unit comes complete with anti-scratch rubber feet and 1.8 metre mains power cord. The is
fully guaranteed for 2 years against parts and labour.

Equipment Description
Layout
1. Channel output sockets:The four output sockets connect to the lamps.
2. Overload Circuit Breaker: The circuit breaker protects the from overloading
and faults.
3. Channel faders:These faders control the channel output levels.
4. Master Fader: Controls the overall level from the channel faders and from the chaser.
5. Flash buttons: Allow each channel to be flashed to maximum.
6. Chase button: Activates the internal four channel chaser.
7. Chase Fader: Controls the Chase rate.
8. Audio Chase button: Turns on the internal microphone for the audio-triggered chaser.
The Chase Fader controls the minimum chase rate in the absence of sound.

Dimmer Operation
After unpacking, check for any obvious faults or defects. If any are apparent, return the unit to the place of
purchase.
Unwrap the power cord and plug into a GPO. Plug four lamps into the four output sockets and switch the
power on at the wall and the rear panel. Advance the Masterfader and a channel fader. The mimic LED
for that channel will light, at an intensity corresponding to the lamp connected to that channel.
The Masterfader provides overall control over all four output channels, and also provides level control for
the chaser.
The Flashbuttons below the channel faders will always flash to full irrespective of the Masterlevel.
To operate the chaser, advance the Masterfader, and press the Chaser On switch. The Chase rate is
adjustable from zero to maximum by the Rate fader on the left. To disable the chaser, press Chaser On
again.
If desired, the chaser can be triggered by audio sound levels at the . With the chaser on, press
the Audio switch. In the absence of any sound, the chaser will now step at a rate determined by the rate
control as before. Any loud sounds will be detected by the internal microphone and advance the chaser
accordingly.
Both the Chaserand Audio functions have LED indicators showing when each function is on.
Note that at no time should the total load on the exceed 2400Watts. If this occurs, the overload
circuit breaker will trip. Take the Master to zero before resetting the overload circuit breaker. This
maximum power (2400W at 240V AC) may be supplied by one channel, or any combination of channels.
For example: If four 2400W lamps were connected to the four outputs, only one could ever be fully on at
any one time. Eight 300W lights (such as PAR 56s) may be run continuously at "full" without risk of
overload.
Maintenance
With care, the will require little or no maintenance. Covering the unit while not in use prevents
entry of dust into the faders, increasing their useful life. This also minimises the risk of entry of liquids inside
the chassis, which would be both damaging to the unit and dangerous to the operator. During cleaning, do
not spray directly onto the unit, but onto a rag and wipe clean.
