FSR BMS-1032-BASE BMS-1032 system main unit
Description FSR BMS-1032-BASE BMS-1032 system main unit The FSR BMS-1032-BASE Background Music System is professionally designed capable of selecting between 10 stereo audio sources from an elegant wall plate. It comes utilizing a single CAT-5 cable, the digital stereo audio and control signals is possible to be transmitted and distributed to up to 32 rooms per system. The BMS-1032-BASE Background Music System is working along in conjunction with all distributed music systems (AEI, DMX, Muzak), as well as any audio source (i.e.: CD, DVD, etc.). The system is carefully designed for "sky boxes"; luxury suites; small salons; professional offices (doctors, lawyers, commercial suites); cruise ships; and just about any space that is wanting a selection of multiple background music sources. A rack or shelf mount chassis, 2 rack units high. This chassis will accommodate the main audio input card and up to eight stacking 4-room output cards. Up to 32 rooms will be handled in this unit. An audio control plate (2-gang) is provided for each room. The headphone jack allows for private listening (if desired). There are two sets of up/down buttons which control volume and channel selection. Numbers 0 through 9 are in the main system, and “L” selects the" local" units. The power supply(s) is provided with the system.

D/A Converter Performance Resolution 18 bits Sample rate 44.1k samples/second (CD quality) Dynamic range 94dB Conversion Method 128x oversampling delta-sigma modulator with digital anti-alias filtering Audio Transmission Method AES-3 digital encoding Page Audio Inputs Input Type Mono Balanced Input Impedance 20 k ohm Nominal Input Level 0dBV/0.775 VRMS Max Input Level Before Clipping +12dBV/2.9 VRMS (with trim control set to unity) Input Trim Control Range -20 to 14dB Crosstalk -85dB Page Detection Threshold -25 to -5dBV (this is the level required to trigger a page with trim set to unity) Page Detection Delay 50 milliseconds max Page Hold Time 2 seconds (internally adjustable from 0.1 to 8 seconds) Number of Page Inputs 2, may be enabled in any combination by programming each wall plate. Wall Plates Specifications Volume control range -40 to 0 dB Local Audio Input Local Input Stereo Unbalanced Local Input Gain 10db fixed Nominal Local Input Level -10dBV/0.25VRMS Max Local Input Level +dBV/1.0VRMS Audio Output Line Output Stereo Unbalanced Gain Unity with respect to rack audio inputs, when rack trim control is set to unity and wall plate volume is set to max. Distortion 0.065% @ 1VRMS, 1kHz, 1k load wall plate volume max. (typical) Speaker Output Power 0.75 watts/channel RMS 2.5 watts/channel music power. Speaker Impedance 8 ohm recommended Distortion 0.3% @ 0.75 watts into 8 ohms 20Hz-20kHz. Mono Jumper When installed, sums left & right rack audio, and feeds it to both left & right outputs. Local inputs remain stereo-bridge them separately for mono operation. Headphone Output 1/8” jack provided for connection to 16-32 ohm headphones. Headphones are automatically sensed, and disable line and speaker outputs when plugged in. Page audio unconditionally overrides this feature reenabling all outputs for the duration of the page.
