The Wolff Audio RefPre is a premium 500 Series reference preamp designed for pure, uncolored sound reproduction. Built with minimal circuitry and a transparent signal path, this preamp ensures that your recordings capture the truest representation of your microphone and instrument sources. Whether you're working with high-output condenser microphones, dynamic mics, or delicate ribbon microphones, the RefPre offers exceptional headroom and precision. Originally developed for the Wolff Console, it boasts 60dB of gain, with an additional 10dB boost in Ribbon Mic mode, along with auto impedance adjustment and phantom power lockout for added safety. This preamp is an excellent choice for professional recording studios, broadcast environments, and engineers who demand the highest fidelity. Features such as a switchable polarity reverse, 48V phantom power, an 80Hz high-pass filter, and relay-based gain adjustments provide flexibility and reliability. The front-panel instrument input with a dedicated Hi-Z input amp makes it versatile for both mic and line-level sources. With a frequency response of 10Hz to 80kHz (±0.5dB), ultra-low distortion (0.0005% at 60dB gain), and high headroom (+28dBu output), the RefPre is perfect for applications requiring accuracy, from emulation microphones like the Slate VMS to instrument miking with Earthworks and Neumann models.
