Basic announcements and playback can be run from the stage manager’s panel backstage right. Live sound for the concert hall is generally run from the Tech Row, approximately 61' from the stage. Mixing console, equipment rack, effects processor, microphones, portable speakers and other audio inventory is shared throughout the Center, and is dependent on availability.

Acoustic design

Dekelboum Concert Hall is a very "live" room, uniquely designed for live acoustic music. The hall is equipped with 24 acoustic curtains. 


There is a 4 channel clear-com headset system with panels distributed through the space. The main outlets are back stage right, back stage left, Tech Row and the follow spot positions.

Infared system

This system distributes two audio feeds via the infared emitter panels located in the Concert Hall. Guests needing hearing assistance may check out infared receiving headsets from the Guest Experience department prior to a performance. This system usually uses the house audio feed as the audio source. However, it is possible to use this technology for the purposes of translation, etc.


  • There is no additional inventory available for this space.
  • There are 6 specials on 3 circuits that can be refocused if needed.
  • Refocusing of the light plot requires approval of the Technology Manager.
