The Warm Lifter’s JFET input impedance of 2.4 kOhms consistently acts as a matching interface between low-output microphones and interfaces/mixers, solving common impedance mismatch issues such as signal loss, altered frequency response, and phase problems.

The selectable 100 Hz high-pass filter removes irregular low frequencies for improved clarity and detail. Ideal for reducing proximity effect present in vintage ribbons and dynamics.

The selectable 3 kHz treble boost emphasizes upper mids and highs for enhanced clarity and detail, especially beneficial for darker microphones. Perfect for adding brightness and presence to vintage ribbon and dynamic microphones.
