City of Santa Ana Public Library Renovation <br />Smith, Fause & McDonald Inc.Group 4 Architecture Research + Planning, Inc. <br />Conform SetASI #026 – August 72, 20254 Group 4 Project No. 22575-01 <br />SECTION 27 4116-38 INTEGRATED AUDIOVISUAL SYSTEMS AND EQUIPMENT <br />c.Allows the expansion of wireless microphone systems by splitting one pair of <br />antennas to multiple receivers. It also amplifies RF signals to compensate for <br />insertion loss that results from splitting signal power to multiple outputs. A <br />single system can support up to four wireless receivers. <br />3.Function/Features/Performance: <br />a.WMRX/WMIC LAV <br />1)Operating Range Under Typical Conditions: 100m (300 ft.) Note: <br />actual range depends on RF signal absorption, reflection, and <br />interference. <br />2)Audio Frequency Response (+/– 2 dB): Minimum: 45 Hz; Maximum: <br />15 kHz <br />3)Total Harmonic Distortion (ref. +/– 38 kHz deviation, 1 kHz tone): <br />0.5%, typical <br />4)Dynamic Range: >100 dB A-weighted <br />5)Operating Temperature Range: –18°C (0°F) to +57°C (+135°F) <br />Note: battery characteristics may limit this range <br />6)Transmitter Audio Polarity: Positive pressure on microphone <br />diaphragm (or positive voltage applied to tip of WA302 phone plug) <br />produces positive voltage on pin 2 (with respect to pin 3 of low <br />impedance output) and the tip of the high impedance 1/4-inch output. <br />4.Manufacturer, WMIC LAV System: <br />a.Shure QLXD24/SM58 Digital Wireless Handheld System w/ SM58 Cartridge, <br />Shure QLXD14 Bodypack System, and Shure WCE6T Omnidirectional <br />Condenser Rigid Earset Microphone, tan. <br />b.Or equal. <br />B.High Definition A/V Transmitter <br />1.Drawing Reference: DMTX <br />2.Functions/Features: <br />a.Provides HDMI, RGBHV and mini stereo audio inputs <br />b.Provides USB extension <br />c.Provides LAN connectivity <br />d.Transmits audio, video and control signaling to specified receiver over a <br />single UTP6-4P cable. <br />e.HDCP compatible. <br />f.Can be remotely powered by specified control system. <br />g.Mounts to underside of table. <br />h.Nominal dimensions: 6.5” x 7” x 1.5” <br />3.Manufacturer <br />a.Crestron DM-TX-201-C <br />b.Or equal. <br />C.HDMI and RGBHV w/ Stereo Audio Input Plate <br />1.Drawing Reference: MP1 <br />2.Features/Functions <br />a.Inputs <br />1)HDMI <br />2)RGBHV <br />3)Stereo Audio <br />4)USB <br />b.2x1 combination digital/analog switch <br />c.Supports resolutions up to 2048x1080 @ 24Hz <br />d.Analog-To-Digital Conversion 10-bit 165 MHz per each of 3 channels <br />e.Communications <br />1)Audio, video and control 330 feet over a single UTP Cat 6 cable.
