The AVP1 audio- visual interface is standard dual-gang wall plate that allows the line- or speaker-level outputs of movie projectors, audio and video tape/cassette recorders, phonographs, etc., to be connected to microphone inputs of house P.A. systems. The AVP1 provides audio interfacing and isolation with wide frequency response and low distortion. The AVP1 provides a 1/4” phone jack input for movie projectors and similar monaural A/V equipment. This input allows the AVP1 to be safely connected to the speaker outputs of older tube-type equipment: a 16-ohm, 5-watt load resistor simulates the speaker impedance to prevent damage to the amplifier output stage, while a high-frequency filter reduces hiss from noisy electronics. Left and right RCA phono jack line inputs are resistively mixed to monaural, a handy feature for use with CD players and cassette recorders. The DBT-1 transformer provides floating 150-ohm output to an easy-to- use screw-type barrier strip for fast wiring installation. The HUM CANCEL switch eliminates hum and buzz from AC ground loops between equipment. For further versatility of operation, there is also an independent low-impedance microphone input via a female XLR-type connector wired to the output barrier strip. The AVP1 is built on a standard stainless steel or black anodized aluminum wall plate designed for mounting in any standard two-gang masonry box. With its lustrous brushed finish and laser engraved legends, the AVP1 is both functional and attractive, complementing a wide variety of decors.
