1.2SYSTEM DESCRIPTION
.1The following is intended to provide an overview of the design concepts and is not an exhaustive description of the Systems. Generally, ceiling or surface speakers are specified depending on the ceiling type, room finish and reproduction quality requirements. Typically, provide surface mounted loudspeakers in rooms with no ceiling and recessed loudspeaker assemblies in areas with a finished ceiling.
.2Each reinforcement system is designed to provide high level, full range speech and music to all seats in the area. The system is designed to equal or exceed the sound quality of other contemporary similar facilities.
.3The speaker system should provide sound levels of at least 105 dBA (continuous) with a seat to seat variation in coverage of +/- 2.5 dBA or less.
.4The general loudspeaker configuration for each large open area is to have main full range and low frequency loudspeakers (also referred to as the MAIN loudspeaker system) supplemented with “fill” or “delay” speakers.
.5Power amplifiers and speaker signal processors will be centrally monitored in the Control Booth.
.6The Control Booth is located where floor microphone inlet and tielines terminate. Wireless microphone, local program sources, patch frames and a primary mixing console will be housed here. The amplifier and DSP control computer will also be located here. The control booth will distribute audio to each sound reinforced room in the facility as selected by hard patching or DSP control for those rooms. Input panels are located throughout the facility to permit connection of microphones, monitor speakers, intercom and other audio cables as required. These panels will also permit the use of microphones “snakes” with multiple outlets for special events.
.7All house mic lines will be routed in copper cabling to the Control Booth, where they terminate onto a patch frames.
.8Dedicated AV network switches and support equipment are supplied to assure reliable audio transmission. For longer transmission runs between audio devices, dedicated optical fibers are used to carry the digital audio. Shorter distances are managed by copper category rated cable.
.9As an aid to the emergency system, the loudspeakers will receive warning signals and announcements from the main fire command center. Tie lines to interface these systems will be the responsibility of the Contractor. During an emergency with the fire alarm, all systems other than those that cover the main bowl shall mute. A flashing indicator should warn the control booth operator that the Emergency system has taken control of the sound system.
.10Interview/Multi-purpose Room: A ceiling-mounted projector displays sources onto a large recessed ceiling-mounted screen. Sources available for display are: Bluray/DVD playback or sources connected to the rack-mounted input plate. The input plate contains connectivity for a laptop computer, or auxiliary video source with stereo audio. A wall-mounted control panel provides the touch screen interface for control of the in-room system components. The control system provides control of: transport controls of the Bluray/DVD player, Screen Up/Down, Video Projector On/Off, source selection and volume.
.11Conference Room: Conference rooms can be operated separately or if separated by a removable divider they can be operated together. In-room input plates are routed through a collective matrix switcher which allows the viewing of any input plate source onto any or all of the video projectors. Each conference room contains a BluRay/DVD playback unit. Either Blueray/DVD player can be viewed on any or all of the video projectors. Transport controls for the Bluray/DVD player will be via in-room control panel. Each Conference Room also contains a wall-mounted control panel. The control panel will contain a password protected page for the combining and uncombining of the rooms. The password protected page will prevent unauthorized or accidental sending of sources to adjacent rooms. The in-room control panel will also allow source section as well as microphone and program volume control. The control processor will control the DSP processor via the LAN.
