Pre-Amplifiers for whole-house audio

Audio preamplifiers take a line level audio signal (usually left + right analog audio) and tweak it. They may split it to multiple line level signals, switch the output to one of several sources, raise or lower the volume level, mute, etc.

They do not boost the signal level to speaker level audio; then they would be called an amplifier, not a preamp.


RP41AV
Remote Preamp
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.
Hide
  • 4 separate line level A/V inputs, simply labeled 1, 2, 3, and 4, accessed in any order from the RC68X Hand-Held Remote/Programmer's infrared commands.
  • Separate Volume (Up/Down), Balance (Left/Right), Bass and Treble controls feature continuous adjustment in 2 dB steps, in either direction, all IR controlled.
  • Balance, Bass, and Treble controls have a Flat function (on the RC68X) for instant return to flat response for any previous setting.
  • Separate Mute On and Mute Off fuctions are included so that you can give a positive command without knowing what the status is. This is very helpful in remote
  • areas when all adjustments are made 'blind' without any visual aids for status.
  • IR control input port connects to the emitter output of Xantech devices, allowing remote control from keypads, IR receivers, connecting blocks, etc.
  • Tone controls allow individual 'EQ' of each room in multi-zone installations.
