A. Control System

1. Control consoles and locations

The main console is an ETC Expression 2x located on the 3rd floor in the light booth. This console has a separate DMX run to the dimmer rack, the FOH catwalks, and up-stage right. The console has been upgraded to run version 3 software.

The secondary console is an ETC Express 125 and is located in the stage manager panel at down-stage left. This console is also running version 3 software.

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

2. Houselight Control

All houselights, work lights, and aisle lights are on dimmers and are addressable by DMX by either console. They may also be controlled using a ETC Analog Address system. There are 8-channel slider stations located at the stage manager panel and in the sound booth. In addition, there are worklight buttons at both upstage personnel doors, and panic buttons (for houselights and worklights) at all house doors. All worklight 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 Lee-Colortan ENR-series racks. 352 2.4k dimmers are available, as well as 4 6.0k dimmers. Power is provided by a 800-amp 3-phase disconnect.

A road-show disconnect is located upstage right and provides 3 legs at 400-amps (5 wire). A campus electrician is required to lug-on and off of the disconnect. All shows requiring use of this disconnect must make arrangements with the technical director prior to load-in.
