Wunder's version of the 1073 (Preamp only), a little Cobalt in the Transformers gives this preamp its kick, not to mention 4 channels!
The Wunder Audio PAFOUR is the 19" rack mount, four-channel microphone preamplifier version of the PEQ1. The PAFOUR is a fully Class-A discrete 1970's-style mic-pre utilizing the exact mic-pre circuit as the PEQ1. The design employs proprietary, custom-designed mic, and output transformers. It is no secret that the huge sound is due to the make-up of the Mu-Metal transformers. In the PAFOUR, you get four channels of the Wunder Audio sound in one unit!
