The EZ-PH1 is a stereo phono preamplifier with front-panel volume trimmers and audio level metering. Stereo RCA jacks and a
grounding screw are provided on the rear panel for connecting a turntable tone arm. The input is preamplified with RIAA equalization
to feed the line output RCA jacks. Left and right channel front-panel LED VU metering facilitates adjustment of the level trimmers.
The EZ-PH1 is ideal to add phono inputs to mixers and amplifiers with line inputs, or for direct connection to recording decks for
dubbing records onto other media. It is used in clubs, educational facilities, homes and studios.
