Wunder Audio PAFOURplus
The Wunder Audio PAFOURplus is a fully Class-A discrete 4-channel mic-pre. The design employs proprietary, custom-designed mic and output transformers.
The Wunder Audio transformers are the key to the sound. The PAFOURplus has Wunder Audio’s exclusive new generation NICO transformers. The cores in the transformers are made up of Nickel, Iron and Cobalt. The NICO transformers are physically large and just barely fit into the 1U rack mount housing! Cobalt is the ingredient that gives the mu-metal it’s vintage sound, being identical to vintage laminate cores of the 1050’s through the 1970’s.
The Wunder Audio PAFOURplus is the 19" rack mount, four-channel microphone preamplifier version of the PEQ2. Wunder Audio 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/Cobalt).
- 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
The PAFOURplus utilizes the exact mic-pre circuit as the PEQ2. But with the PAFOURplus, you get four channels of the Wunder Audio sound in one unit!
