A. Control System

1. Control consoles and locations

The main console is an ETC Ion located on the 3rd floor in the light booth. This console has a separate DMX run to the dimmer rack and up-stage right. 

The secondary console is an ETC Expression 2x and is located in the stage manager panel at down-stage left. This console is running version 3 software.

Both consoles are connected to an ETC Response DMX merger and can control the dimmer rack simultaneously.


2. Houselight Control

All house lights, work lights, and aisle lights are on dimmers and are addressable via DMX by either console. They may also be controlled using the ETC Analog Address system. There are 8-channel slider stations located at the stage manager panel, in the sound booth, and in the lighting booth. In addition, there are work light buttons at both upstage personnel doors and panic buttons (for houselights and work lights) at all house doors. All work light and panic buttons may be disabled using a key-switch at the stage manager panel.



B. Dimming and Road-Show Power

The house dimming system consists of 4 full racks of ETC Sensor+ Dimmers. 356 - 2.4k dimmers are available. Power is provided by an 800-amp 3-phase disconnect.

A road-show disconnect is located upstage right and provides three legs at 400 amps with Cam lock ends. Bare ends tie-in is available with a campus electrician required to lug on and off the disconnect. An additional 100-amp disconnect is also available with bare-end tie-in only. All shows requiring the use of these disconnects with bare-end connections must make arrangements with the technical director prior to load-in.
