Threeset consoles for 60, 80, 100 or 120 STM or XTM Thyristor dimmers, have three presets each with separate three-position switches to group to the three master faders provided for each preset. An additional master fader, making ten in all, is provided to inhibit the response, on all presets, of a permanent group of channels selected at the time of order. Each control channel has three identical dimmer levers, all with quadrant scales, and three lever-action switches. On each preset the three position switch, with a 30° separation between adjacent positions, is mounted immediately above the dimmer lever to ensure a clear indication of the grouping. One preset, and all the master faders, associated group blackout switches and the dead blackout switch, are housed in a low-back, freestanding centre desk. The other two presets are mounted on the two slopes of a shaped wing unit. All controls are within reach of a seated operator, but the desk and wing arrangement does not preclude the help of an assistant. Provision is made to house other accessory controls which need to be within reach; a sweep-second clock, levers for auditorium and presentation lighting and a dimmer for local lighting are already fitted. |
