Wolff Audio released a statement on Tuesday, enthusiastically introducing the public to the 500 Series RefPre.
"The preamp that champions ribbon mics without ever coloring your sound," they said. "Its ultra‑transparent, transformerless design and minimal signal path ensure every nuance of your mic’s smooth highs and rich lows comes through pure and untouched."
The preamp, they say, is for "when you need to tame a high‑output ribbon or coax delicate detail from vintage models."
Details, directly from Wolff Audio, are as follows.
- Ribbon‑Ready Gain: Stepped rotary control from –10 dB to 60 dB, plus a dedicated +10 dB ribbon circuit with auto‑impedance matching and phantom‑power lockout
- Pristine Headroom: +28 dBu output and –125 dBu EIN keep noise and distortion invisible. Even at extreme settings
- Pro‑Level Tools: 80 Hz high‑pass filter, polarity switch, front‑panel Hi‑Z input, and hard‑wired relay bypass for true signal integrity
- Rock‑Solid Reliability: All gain stages and switches are relay‑based, built to last session after session
"Originally crafted for the Wolff Console, RefPre shines as a stand‑alone 500‑series module in studios, broadcast suites, or any rig that demands total fidelity," they say. "Swap in RefPre for your ribbon, dynamic, or condenser mics—and rediscover what transparent really means. Ready to elevate your recordings? Try RefPre today and experience your gear exactly as it was meant to sound."
