B. Auditorium
1. AV Presentation System
a. General
(a) The AV presentation system in the auditorium will provide one large, centered screen
projected display of video sources. The display will utilize a projection screen that is
mounted downstage of or within the header of the proscenium wall. Alternatively, the
screen could be integrated on a theatrical rigging lineset. The screen will be raised (out
of sight) when not in use. The screen size shall be determined based on the size of the
auditorium for good legibility of data-based images.
(b) The projector shall be sufficiently bright to display the image without dimming the in-
house lighting completely. The minimum resolution recommended for both computer
signals and video at that screen size is 1920 X 1080.
(c) All sources being shown through the AV system should be distributed from a rack-
mounted matrix switcher. or AV over IP solution. All sources have both video and audio
components. Video inputs shall be located conveniently around the room and may
include the following:

individuals near the stage manager’s position backstage, opposite stage position,
dressing rooms, green room, in production support locations, and the lobby.
(b) Image capture shall be done with a PTZ camera mounted on the back wall of the
Auditorium. for capture of presentation or program. Camera shall be statically set on a
wide shot view of stage area. The camera feed shall be sent to monitors around the
auditorium.
c. Production AV Infrastructure
(a) A network of AV tie line connections will be located around the Auditorium that will
allow AV signals to be sent to any other tie line locations within the Auditorium. These
tie lines will allow multiple projectors to provide scenic backgrounds for theatrical
productions or live video mapping throughout the Auditorium.
(b) Tie line connections will terminate in an equipment rack panel that serves as a patch
bay. A loose equipment schedule is provided to include necessary components for
temporary setup of theatrical video mapping. Loose equipment may include, but is not
limited to, video transmitters, video receivers, patch cables, projectors, and project
specific projector lens options that are field verified based on throw distances. Provide
two lenses for each projector. Coordinate projector lens options with TCCD.
d. Instructional Equipment
(a) Provide loose AV equipment for instructional purposes on the stage to comply with
TCCD standards for educational AV media.
2. Sound System
a. General
(a) The sound audio system shall provide audio support for theatrical and musical
productions, video presentation, and general assembly. The main audio control
position shall house a front-of-house (FOH) digital mixing console along with the
program sources such as media players, recorders, and other audio interfaces.
(b) Wireless microphone receivers shall be located in an equipment rack located in the
main audio control position. Antennas shall be located at the catwalk level for direct line
of site to the stage and performers. All channels shall be equipped with belt-pack
transmitters, miniature headset microphones and lavaliere microphones with at least
half the channels equipped with handheld transmitters.

microphones shall be a mixture of dynamic, condenser and microphone packages for
instruments. Direct boxes of various types shall be provided for interfacing to other
audio producing sources.
(d) Microphone inputs from the stage panels, apron floor boxes, and the rigging shall
terminate to the digital mixing system. Microphone inputs in the rigging shall be used
for hanging choir microphones distributed across the stage. Digital audio snake
connections shall also be provided on stage, within an orchestra pit (where applicable),
and at the main control position.
(e) The presentation system shall allow for the operation of the sound system without the
use of the large digital mixing console. The stage managers position (SMP) equipment
rack(s) shall be located at the side of the stage and shall be equipped with an analog
rack-mounted mixer, a media player for program playback, media recorder and
