Ideal Partner for Low Output Microphones in the Studio and on StageWarm Lifter is a linear, active microphone preamp designed to provide powerful amplification for dynamic and ribbon microphones with low output levels. It features advanced functions for both live and studio use. The sweet tones of classic low-output microphones, heard on countless studio and live recordings, benefit from the sufficient power provided by high-quality high-gain preamps, bringing out the full frequency spectrum and tonal characteristics of the microphone. Warm Lifter offers a high-impedance microphone preamp with clean analog gain, tone filtering, and a balanced JFET input, all in a compact size and affordable price.

Perfect Sound AmplificationWhen working in the studio with a low-power interface or on stage with very long cables, there may be insufficient microphone gain. Warm Lifter provides 26 dB of analog gain with true impedance matching, ensuring that any low-output microphone you connect receives the professional power needed to connect to audio interfaces or mixers. Adding Warm Lifter gives you the extra headroom necessary to bring out the rich detail in the lower midrange, characteristic of passive ribbon microphones and many dynamic microphones, without adding digital artifacts or losing tone due to long cables. In addition to gain, Warm Lifter features a high-pass filter at 100 Hz and a 3 kHz shelf boost for shaping sound.26 dB of Pure Analog GainWarm Lifter's signal path starts with a balanced JFET input with an impedance of 2.4 kΩ, delivering 26 dB of pure, analog gain. Having 26 dB of gain before reaching the digital level is extremely beneficial as it avoids the need to significantly increase the digital gain of the mixer or interface, which could lead to artifacts and sound degradation. The JFET input provides enough analog tone to make the microphone sound "open" without adding noise or excessive coloration. The 2.4 kΩ impedance provides excellent frequency response for low-output microphones within typical impedance ranges.

Filtering Critical FrequenciesWarm Lifter features a selectable 12 dB high-pass filter and a 2.5 dB shelf boost. The 12 dB high-pass filter has a cutoff frequency of 100 Hz, located in the middle of the true bass frequency range. Turning on the filter cuts all frequencies below 100 Hz, removing the "rumble" from the sound. The 2.5 dB shelf boost has a cutoff frequency of 3 kHz, located in the middle of the upper midrange frequency range. As a shelf boost, it means all frequencies above 3 kHz will be gently boosted by 2.5 dB compared to the high-pass filter. Because it is a shelf boost, it will boost everything above 3 kHz, adding higher mids, presence, and true highs known as "air" or "sparkle." Engaging this boost instantly adds clarity to your sound.
