The Warm Lifter is an inline active microphone preamp designed to provide powerful gain to low output dynamic and ribbon mics and comes with premium features for live & studio use. The sweet sounds of classic low-output mics that you’ve heard on countless records and live recordings have benefited from the sufficient power provided by high-quality, high-gain preamps, bringing out the full frequency spectrum of tone and sonic characteristics of the mic. Warm Lifter puts a high-impedance mic pre with pure analog gain, tone filtering, and balanced JFET input at your fingertips at an incredible size and price.

Using a low power interface in-studio or dealing with extra long cable runs in a live setting can starve the mic of adequate amplification. Warm Lifter boasts 26dB of analog gain with true impedance matching, so any low output mic you plug in will be professionally powered for connecting to audio interfaces or mixers. Adding the Warm Lifter ensures you have extra headroom necessary to bring out the rich lower-midrange detail and presence that passive ribbons and many dynamic mics are known for, without adding digital gain artifacts or losing tone from aggressively long cable runs. Beyond gain, Warm Lifter also has a 100Hz high-pass filter and a 3kHz high-shelf boost to sculpt tones.

Warm Lifter’s signal path begins with a balanced, 2.4k Ohm (impedance) JFET input that delivers 26dB of pure, clean analog gain. Having 26dB on tap before hitting digital is incredibly helpful, as this should prevent any mixer or digital interface from having to go much beyond 40dB of onboard digital gain. As digital gain increases, the likelihood of artifacts and thinning of sound increases. The JFET input provides enough analog tone to keep the mic sounding “open” without adding any noise or too much color. The 2.4k Ohm impedance will deliver excellent frequency response for low-output mics that fall into typical impedance ranges.
