Lighting Desk

Our studio lighting desk is a 24-channel Siruis, made by Zero88 in North Wales. It has a total of 24 analogue output channels, although we only use 11 of them.

There are two dimmers in the rack. Of one a dimmer channel is severely broken (corresponding to channel 'C'). The transistor looks fried and has continuity between the emitter and collector, also two medium-power 270 Ohm resistors have physically split.

Apart from direct manual control from the faders to the lights, the desk can also store and recall sets of lighting settings, or scenes. This is very useful if the lighting needs to be changed quickly, or there are many different lighting setups to be switched between.

YSTV has two identical desks. One has a key slot to switch between the three options (Run, Program , and something else) the other has a dial. On the desk with the key slot everything seems to work - in the same way as on the one with the dial, currently in use.
