The Wunder Audio PAFOURplus is the 19″ rack mount, four-channel microphone preamplifier version of the PEQ2.

We’ve added new features to every channel of the original PAFOUR to make this new version a definite plus.

PAFOURplus New Features:

  • NEW Beefy Output Stage added just before Output Transformer.
  • Upgraded “NICO” transformers (Nickle/Iron/Colbalt).
  • Discrete Active HP Filter.
  • Output fader.
  • Improved Gain switches, over 3 x the gold contact area per switch position.
  • Light Pipe Pushbuttons replaces small C&K toggle switches.
  • LED metering with Green signal indicator and Red clip light.
  • Gain knob has one extra position to achieve -6db less gain (-24dB).
  • Redesigned Enclosure with thicker gauge metal and tack welded with better RF protection.
  • Thicker faceplate.
  • 1% Metal Film resistors for lower noise floor and better matching from channel to channel.
  • Sturdier amp compensation or RF rejection capacitors.
  • New PCB with revised and optimized component layout with beefier traces.
  • RF filtering.
