Wolff Audio RefPre

The RefPre is designed to be transparent to the source signal. Hear the Mic, not the Micpre. The 500 Series RefPre Reference Preamp stands out for what it won’t do. It won’t color your audio. Never Ever. The transparent design uses minimal circuitry and signal paths.

If your go-to preamp ‘must haves’ include exceptional accuracy and extra headroom to deal with a variety of mic types, including those with high output and ribbon styles, then this preamp has you covered. It also includes a switchable +10dB gain boost and phantom power safety lockout for ribbons.

Try the RefPre for your mic, line, and instrument preamp requirements and it will quickly become your new favorite.

Designed as an option for the Wolff Console, the RefPre has 60dB of gain, phantom power, switchable polarity, and a source selector for the XLR/INST front panel input. The Ribbon mic selection increases the gain to 70dB and adjusts the mic impedance. The RefPre is ideal for sampling and emulation mics, such as the Slate VMS that rely on a fully transparent preamp. Mic pairings with Earthworks TC25 for toms and kick and PM40 for piano deliver exceptional results as does a pairing with the Neumann TLM 103 to add a discernible presence.

The RefPre is a great addition to the audio pro’s toolbox in recording studios, broadcast suites, and for engineers that require the highest fidelity and accuracy for their art.
