The XC42 is a four circuit compact portable dimmer with a load capacity of 1200 Watts per circuit. Each circuit is protected by a 10 Amp fuse. It can be controlled in several ways - the most common being DMX-512. Other control modes are also provided for stand alone operations. These include individual channel control and chaser functions. Individual circuits may be operated as non-dim (relay) circuits. Individual circuits may be set for one of several response curves and may be limited to less than full intensity. In addition to full soft patch capability there is a quick pack address function which enables rapid setup. The XC42 can optionally be provided with a wireless DMX receiver.
