About this item

Designed to boost low-output or passive microphones and facilitate long cable runs, the Warm Audio Warm Lifter boats 26 dB of clean analog gain with true impedance matching, ensuring your mics and audio destinations are always in agreement. With a 100 Hz high-pass filter and a 3 kHz shelving boost, you can sculpt your tones as well.

Common Applications

Studio vocal and instrument recording with low-output ribbon and dynamic mics

Voiceover and podcast recording/streaming

Low-output mics plugged directly into audio interfaces with weak preamps

Compensating for signal loss during long cable runs

True 26 dB of Clean Gain

Warm Lifter will always deliver 26 dB of clean output gain, regardless of the mic that you choose. Unlike some inline preamps, signal boosters, and lifters, the circuit design of the Warm Lifter protects your recording from signal loss or phase issues by ensuring there is no mismatching of impedance between your mic of choice and the Warm Lifter.

Added Frequency Flexibility

The Warm Lifter has a selectable 100 Hz high-pass filter to remove unruly low-end frequencies for added clarity and detail. Additionally, the Warm Lifter has a selectable 3 kHz high-shelf boost to emphasize the upper mids and highs for clarity and detail on darker sounding mics.
