Warm Audio Warm Lifter

The Warm Lifter is an inline active microphone preamp designed for low output dynamic and ribbon mics, with added premium features for live & studio use. Offering 26dB of clean output gain, regardless of the mic that you choose, the Warm Lifter ensures optimal performance where additional gain is crucial for accurate detail and frequency response, especially when connected directly to interfaces. Most notably, the Warm Lifter has two key features including a selectable 100 Hz high-pass filter to remove unruly low end frequencies for added clarity and detail, along with a selectable 3 kHz high-shelf boost to emphasize the upper-mids and highs for clarity and detail boosted on darker mics.

The Warm Lifter houses an ultra low-noise JFET input with a fully balanced (ins/outs) signal path and operates on 48v phantom power. 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. The incredibly durable build quality adds to the total package to deliver a critical piece of audio utility gear that you will want by your side at all times.

26dB Of Clean Analog Gain 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.

Critical Frequency Filtering Warm Lifter has a selectable 12dB high-pass filter and 2.5dB high-shelf boost. The 12dB high-pass filter's corner frequency is located at 100 Hz, right in the middle of the true bass frequency range. Engaging the filter will cut all frequencies under 100 Hz, which will be perceived as removing "boominess" from the sound. The 2.5dB high-shelf boost corner frequency is located at 3 kHz, which lies squarely in the middle of the upper-midrange. This is a shelf-style boost, meaning, all frequencies above 3 kHz will be boosted at a more gentle 2.5dB in comparison to the high-pass filter. Since this is a shelf and will boost everything above 3k, the perceived change will add upper-mids, presence, as well as true high-end, otherwise known as "air" or "brilliance." Engaging this boost will instantly add clarity to your sound.
