MULTI-PURPOSE SOUND SYSTEM Section 16780 15-1207 processing and volume control from the control system (Touch Panel execution shall be provided in the remote control description of this document). a. The music input shall require a 3.5mm stereo unbalanced jack, terminated to a summing transformer with a balanced mono output. This proper interface must be included to insure a high quality audio feed from the wall plates to the equipment rack. b. The microphone inputs XLR-F shall require a non -latching connector to protect from cable damage and ensure safety. 2. Two wireless handheld microphones shall be provided for use in the Gymnasium. The wireless system shall operate in the UHF band between 480 MHz and 790 MHz. Effective range of the system, receiver to transmitter, shall be 100 meters under optimal conditions. The system shall allow selection of over 32 systems operating simultaneously with select frequencies across 36 MHz of bandwidth in orderto avoid RF interface. Optimal frequencies shall be selected automatically, ensuring that individual systems run at their highest level of performance, and that multiple systems in simultaneous use do not interfere with one another. a. The transmitters shall be powered with batteries that are easily accessible. Acceptable battery formats include 9 volt or AA alkaline. Transmitters shall have a power on /off switch, as well as a backlit LCD showing group and channel, peak indication, and battery strength. i. Provide two handheld wireless transmitters ii. Provide one wireless mixer transmitter (i.e. bodypack transmitter) b. The receiver shall have a multi -function display showing group, channel, and frequency; squelch level, transmitter battery strength. The system shall use diversity technology to improve reception, minimize signal dropouts, and achieve the best possible signal-to-noise ratio. Tone key squelch, and noise squelch circuitry shall be built in to the system to provide optimal sound quality and minimize unwanted noise. The receiver shall include an RF meter, an audio- meter, and a volume control c. The sound contractor shall be responsible to provide remote antennas as required. RF wireless coverage shall be limited to the multi -use area only.

The proper selection of the UHF frequency shall also remain the responsibility of the audiovisual contractor. Conduit shall be provided by others as indicated on the plan, however, it remains the responsibility of the audiovisual contractor to properly terminate the antennas and provide antenna amplification as required. Provide wire guards for all antennas. 2.5 REMOTE AUDIO MIXING A. A small portable 4 channel microphone /2 stereo fine mixer shall be provided to control microphones and playback audio from any location within the gymnasium. The audio output from the mixer shall be transmitted to the gymnasium audio system with a wireless bodypack transmitter. T he mixer may also be used for recording, producing a live show or the playback of any computer audio project via computer tracking by tracks using the USS digital audio interface.
