RECEIVING YOUR EQUIPMENT

As soon as you have received your equipment, open the boxes and examine the contents. If the

XLR connectors, the control signal may be daisy-chained from pack to pack. The DMX signal may be

top or bottom hung by reversing the yoke. For portable use, set the Dimmermaster on a smooth, cool

40 degrees Centigrade (105 degrees Fahrenheit). Make certain that the vent holes all have at least 6

mended that no other equipment be connected to the circuit which is used for the pack, including that

equipment in the carton does not agree with your order or the packing slip, contact the factory imme­diately and we will be happy to help you. If any damage is noted, contact the carrier immediately to
file a claim for damages. You can be sure that when the equipment left the factory it was in good
condition, thoroughly tested, and properly packed.

FEATURES

The DM-124D "shoebox" dimmer is a compact unit with one 2400W dimmer. It may be pipe or tree
mounted and is perfect for tight spaces where conventional rackmount dimmer packs are too bulky.
Drawing no more than 20 amps, it may be powered from a single twistlock receptacle.

The unit is controlled by a DMX-512 control signal (0 to +10VDC control is available as a factory op­tion). The starting channel is set on a thumbwheel switch, which also provides load testing and local
control. A status LED indicates the presence of a DMX control signal. With both male and female

terminated at the last pack by means of a DIP switch. Other switches set individual outputs for non­dim operation or force all outputs to full.

INSTALLATION

A Mechanical Installation

For pipe mount use, a C-clamp and safety cable may be added to the mounting bracket. It may be
surface, preferably in an area which remains fairly cool. Maximum air temperature must not exceed
inches of free air around them. Do not block any vent holes. It is essential that this unit have ade-

quate cooling for safe, reliable performance.

B Electrical Installation

The pack consists of one 2400-watt dimming channel. It requires a source of 120 volts AC 50/60Hz
at 20 amperes for full-power operation. The actual amount of power consumed is determined by the

total wattage of the connected loads used; the dimmer itself consumes negligible power. It is recom­on other outlets on same fuse or circuit breaker. If the building circuit breaker trips, it may be neces-

sary to reduce one of the loads.
Power input to the pack is via a flush-mount male connector on the back panel. Any standard heavy--

gauge extension cord will work for this purpose. Always use 3-wire, grounded cables. 12AWG cable
is recommended.
