1.0 INTRODUCTION The PS 630 is a six channel speaker station designed for use in both portable and fixed intercom systems. It incorporates a loudspeaker and a gooseneck microphone and provides full duplex communications within an ASL intercom system. The PS 630 RM model has a small built-in electret microphone. Special attention has been paid to the intelligibility of speech.
5.0 FRONT PANEL CONTROLS & CONNECTOR 1 LISTEN LEVEL control knobs These knobs preset the listen level for each intercom channel. By turning the knob fully counter clockwise, the channel is switched off. For receiving a Call signal whilst the channel is switched off, see #17. 4 MASTER VOLUME knob This knob functions as the master volume control of the listen levels of the 6 intercom channels (see also #1), for both the speaker and the headset.
8 SPEAKER ATTENUATOR trimmer This trimmer adjusts the extent to which the loudspeaker is automatically dimmed when the gooseneck microphone is switched on. It prevents unit feedback if side tone rejection is not sufficient. It also minimizes system feedback or a 'hollow' sound when the gooseneck mics of other speaker stations are switched on. 10 HEADSET connector An XLR-4 connector for the connection of a local headset when private conversation is desired.
7.0 INTERNAL CONTROLS On the main PCB inside the unit there are several adjust controls : 16 BINAURAL ROUTING jumpers In case of binaural use of the PS 630, these jumpers determine – for each channel separately - the routing of the intercom audio to the headset. PGM routing jumpers: 17 CALL RECEIVE jumpers For each channel separately, these jumpers enable or disable the reception of a CALL signal when the channel is switched off.
8.0 TECHNICAL SPECIFICATIONS PS 630 System dynamic range: 80 dB call send signal: +2.8 mA call signal threshold (receive): +2.4 V DC supply voltage: +30 V DC (12 - 32 V DC) power interrupt time (mic mute): 0.1 sec Intercom Line Impedance: 350 Ω (1kHz), 2.2 kΩ (DC) audio level: nom. -18 dBu, max. +4 dBu Mic. Pre-amps gooseneck mic: noise cancelling electret headset mic.
10.0 CABLING The intercom lines (the ‘party lines’) are of the shielded two-conductor microphone cable type. The intercom line connectors are of the XLR-3 type. Audio and Call signals are on pin 3, DC power is on pin 2 and pin 1 is connected to the shield of the cable which functions as the common return for audio and power. The audio signal is transferred in an unbalanced way (see ‘Party Line, Technical Concept’).
