35-Watt Phone Paging Amplifier is the ideal choice within the telephone paging industry. This 35-watt paging amplifier provides signal-activated automatic muting of background music during a telephone page and gradual return of music following a page.
Features: 3
inputs: 1 TEL 1 MIC (Lo-Z) 1 AUX (Hi-Z).
Sensitivity:. 03 mV MIC; -20 dBm Tel; 85 mV Aux. 600-ohm balanced TEL inputer for direct connection to page ports and adapters. TEL input has Automatic Level Control (ALC) for constant page announcement level. Separate MIC input for a low-impedance push-to-talk micrphone. Music input – mutable by external contact closure or activity on TEL input. Separate volume controls for mic paging background music and night ringer. Built-in night ringer can be activated from 90V ring signal or external contact closure. 25V and 70V constant voltage outputs balanced and unbalanced. Wall-mount design provides minimum protrusion from backboard. May be rack-mounted using a rack mounting kit (sold separately). Easily accessible recessed front-panel controls for setting volume muting music etc. RCA jacks provided to allow amplifier bridging to double the number of amplifier inputs and outputs.
