All patch circuits and dimmer outputs are brought out to a patch panel located backstage. Dimming is by qty 6 Zero88 Betapak dimmer packs, giving 36 channels. Additional analogue (0-10v) outputs are available for DMX channels 37-48.
Each dimmer channel is rated at 10A. The dimmers are split across a 100Amp, 3 phase supply giving a maximum load of 25Kw per phase, 75Kw total. Two 63Amp SPN sockets (blue) are available for additional dimmers on two of the phases.
Control is by a Zero 88 Sirius Bullfrog programmable desk (DMX out). This is a memory desk with sub masters. The desk supports the latest firmware version. The house lights dimmer controls and 2Kw Silhouette 2000 follow spots are located in the control room. Spotting is through glass.
Sound System
The sound system is designed around sound reinforcement and backing, not full PA.
The main outputs feed a pair of Tannoy V15 speakers mounted outside the Proscenium Arch, half way back in the theatre a pair of Tannoy V12 are driven via a delay. Main output is 400w, delays are 200w. Delay and equalization are provided by a digital processor (DBX Driverack 260). 4 small speakers can be mounted across the stage front if required.
An inductive deaf loop is configured to operate from the main amplifier feeds.
Foldback on stage is provided by a pair of Tannoy V8, 150w. These are mounted on the ends of bar 1. The amplifiers and processor are mounted in a rack in the control room.
The Mixer is a Soundcraft 16 – 4 desk and can be operated from either the control room, back of the auditorium or backstage. There are 16 tie lines from backstage to the control room and 12 tie lines between the control room and mixer. All tie lines are balanced XLR connectors.
