1.0 GENERAL DESCRIPTION The PS 130 is a single channel speaker station. It incorporates a headset connector, a speaker and a gooseneck microphone and provides full duplex communications. The PS 130 RM model has a small built-in electret microphone. At the front panel are a Volume (listen level) Control, a TALK and CALL button with LED indicators, and trimmers for side tone, speaker attenuation and buzzer volume. Special attention has been paid to the intelligibility of speech.
1 VOLUME control knob This knob adjusts the listen level for the headset and the loudspeaker. 2 TALK button This push button activates the gooseneck or headset microphone. The large green LED indicates if the microphone is switched on. Momentary switching: If the TALK button is pushed and held, the microphone signal is sent to the intercom channel until the button is released.
8 GOOSENECK MICROPHONE The PS 130 is equipped with an electret noise canceling gooseneck microphone. A limiter prevents the microphone preamplifier from clipping when speaking close into the microphone. 9 HEADSET connector An XLR-4 connector for the connection of a local headset when private conversation is desired. The headset must have a can with an impedance of 200 ohms minimum, or have two cans in parallel each 400 ohms minimum. The headset microphone may be a dynamic or electret type. . 4.
