Paging microphone with call station base for use with the RM244V or RM4460 mixer-amps. Connected via RJ45 for both signal and power to simplify wiring. Zone assign buttons enable calling to one or all zones. Pressing the page button mutes all audio playback and plays one of 8 selectable chimes, opening the microphone to the selected zone(s). Pressing the reset button mutes the microphone and resumes background music playback to all zones. This system offers 4-zone paging without the additional cost of using a quad amplifier.Dimensions: 460 x 140 x 115mmvbCrLfWeight: 670gvbCrLfMax. connection length: 100m (CAT5 cable) or 1km with optional 24Vdc adaptor vbCrLfConnectors: RJ45 to amplifier, 24Vdc power jack, 3.5mm aux invbCrLfPower supply: 24Vdc, 500mA from RJ45 or optional adaptorvbCrLfOutput impedance : balanced: 600 OhmsvbCrLfOutput level: 10dBVvbCrLfInput level: Mic: -46dBV, Aux: -10dBVvbCrLfInput impedance: Mic: 600 Ohms, Aux: 50k OhmsvbCrLfS/N ratio: -60dB (all channels selected)vbCrLfInterface: RS-485 controlvbCrLfZone assign: 4 zones or all selectablevbCrLfFrequency response : -3dB: 150Hz - 22kHzvbCrLfCapsule: Back electret condenservbCrLfPolar pattern: CardioidvbCrLfControls: Aux/Mic/Chime levels, chime DIP switches, zone/page buttons
