The Warm Audio Warm Lifter Inline Active Microphone Preamp is designed to breathe life into low-output dynamic and ribbon microphones. Whether you're recording in the studio or performing live, the Warm Lifter provides professional-grade power and tonal sculpting to capture every sonic detail.

26dB of Clean Analog Gain ensures optimal performance for low-output mics, preserving pristine audio quality. True Impedance Matching eliminates signal loss, phase issues, and frequency response problems commonly encountered with mismatched impedance.

Unwanted low-end rumble is removed for enhanced clarity with a selectable 100Hz high-pass filter. Darker mics gain presence and articulation with a selectable 3kHz high-shelf boost.

An ultra-low-noise JFET input and balanced signal path deliver clear, transparent amplification. Seamless integration with most audio interfaces and mixers is achieved with 48v phantom power.

The Warm Lifter's rugged construction is built to withstand the rigors of studio and live use. Every unit is meticulously hand-tested in Austin, TX by passionate audio professionals, ensuring exceptional quality control.
