1.05 SYSTEM DESCRIPTION
A.Sound Reinforcement and Playback System:
1.The sound reinforcement system shall be used for the reinforcement and monitoring of live stage sound, archival recording, lecture/narration, amplification and for the distribution of prerecorded audio (CD, DVD, MP3, etc) throughout the audience environment. The primary sound control position shall be located in the control booth at the rear of the auditorium.
2.Left/Right loudspeakers will be installed to provide stereo coverage of the audience areas. Existing center loudspeakers will be verified and reused if suitable. The center loudspeaker cluster will be programmed in the DSP to function as a center channel. This center channel will be used for voicelift in the auto mix function.
3.The sound system will not provide emergency paging capability. All installed sound system loudspeakers shall be configured to be automatically muted by the building life safety system in the event of an emergency. Muting shall be initiated upon receipt of a dry contact closure signal from the building life safety system to relay contacts on the digital signal processor. Coordinate requirements with Section 28.
4.A mixing console will be provided for use in the control booth and at the back of the house via a pass-through. The console will accommodate the various live and recorded program inputs during performances and rehearsals. Playback, archival recording and signal-processing equipment will be located in an equipment rack adjacent to the mixing console.
5.Wireless microphones will be located in the mixing console portable rack and shall be directly terminated to the console. An antenna combiner shall be installed in the portable rack.
6.Microphone and line-level audio signal distribution will be accomplished using traditional shielded-pair copper wiring. Existing microphone circuits shall be surveyed and reused if possible. New wire shall be run to all existing circuits and terminated according to the Drawings.
7.The wiring infrastructure will accommodate the in-house equipment and permit easy interface of future portable or rented equipment, and equipment brought in by outside performers.
8.Mixing console will be labeled in a permanent and clear manner as to channel and device function e.g. wireless mic #1, #2, #3.
9.A series of existing microphone circuits will be modified to accommodate an automatic microphone mixer that will allow end users to have easy access to the sound reinforcement system.
10.Existing microphone circuits not used for the automatic microphone mixer shall be routed to the XLR patchbay. Please survey and confirm quantity, location and condition.
B.ADA Assistive Listening System:
1.An assistive-listening system shall make use of wireless radio frequency transmission technology. This system shall assist patrons with a hearing impairment to better hear the performance by means of wireless receivers.
2.Receivers are included in quantities and types according to the current guidelines and requirements of the Americans with Disabilities Act (ADA).
3.Program signal shall be normally derived from the program monitor microphone. Additional signal sources shall be patched as required.
4.Receivers shall be in the form of wireless headsets, which shall provide additional capability to interface to individual induction-loop and other devices to permit more direct coupling of the received signal to a patron's compatible hearing aid device.
5.The system shall transmit the audio signal via a remote FM antenna located in the Control Booth. Coordinate FM transmitter frequency selection to ensure that a clear channel is used.
C.Video Projection System:
1.The video projection system shall consist of a high brightness, high resolution video projector and video playback equipment. The video projector will be mounted on an articulated motorized lift above the seating area, on the centerline of the projection screen. The projector lift will have three preset stops: storage, operation and maintenance.
2.The projector shall have a minimum native resolution of 1,280 x 800, 5,000:1 contrast ratio and 5,000 ANSI lumen light output (center lumen).
3.The video presentation system shall consist of an input switcher capable of accepting composite video, HDMI, HD/SDI, RGBHV, S-video, computer video and line level audio signals. The switcher shall also have an integrated scaler, and allow for seamless switching of video and audio. Video sources shall include DVD/Blu-ray playback and laptop audio/video connections (“LAP” AV plates).
4.Video playback equipment shall be mounted in an equipment rack in the control area and include a DVD/Blu-ray player as well as a connection for a laptop computer.
5.The existing motorized roll-down projection screen will be used if a field inspection indicated that it is suitable. Control of the roll-down screen will be located at the control booth both as a control system preset and as a hardwire manual override.
6. The video project shall be protected against theft using a single master-keyed device.
Sonic Shock 5 shall be supplied as "single master-keyed device". All security and anti-
theft keys are to be turned over to the owner as part of close out submittal.*
