The RP41AV is a fully functional infrared remote controlled audio/video preamp, replacing the RP41. Volume, Bass, Treble, Balance and Mute functions, plus A/V switching, provide all the functions needed for multi-room systems. It features a low noise, low distortion design with greatly increased headroom capability, for highest audio and video performance. The 'flat pack' design addresses the need for reduced space requirements as multi-room, multi-zone systems grow in complexity.
