The AVP1V is a dual-gang wall plate mounted interface device that allows the line-level outputs of audio and videotape/cassette recorders, phonographs, etc. to be connected to microphone inputs of house P.A. systems. It has the added feature of a 10kW linear input level control and is available on a brushed stainless steel or black anodized aluminum wall plate.

• Speaker Input - 1/4" 3-conductor phone jack, wired for use with standard 2-conductor plug, accepts signals from unbalanced line level or speaker-level sources such as phonographs, audio and video tape recorders and movie projectors. Has 16-ohm, 5-watt dummy load, 20 dB attenuator network, and low-pass filter (-3 dB @ 8 kHz, 6 dB/octave). Input impedance: approx. 16 ohm.
• LINE INPUT L/R - RCA phono jacks, resistively mixed to monaural, for signals from nominal -10 dBV sources such as radio, cassette or VCR outputs. Input impedance: approx. 4 kohm.
• MIC INPUT - Female 3-pin XLR-type connector provides independent microphone input (brought out to output barrier strip) for announcer, lecturer, etc.
• HUM CANCEL - Ground-lift switch, used to reduce hum and buzz by eliminating ground loops and providing proper grounding for various conditions. Breaks connection between input and output shields.
