Warm Audio WA-WL Warm Lifter Inline Active Microphone Preamp The Warm Audio WA-WL Warm Lifter is designed to boost the signal from low-output dynamic and ribbon microphones, providing the necessary gain without introducing unwanted artifacts. Its analog circuitry includes a 2.4k Ohm JFET input, offering a high-quality connection between your mic and your interface or mixer. With 26dB of clean gain and tone-shaping features like a high-pass filter and high-shelf boost, the Warm Lifter ensures clear, detailed sound across the entire frequency spectrum. Whether on stage or in the studio, it gives you the headroom needed to capture all the richness of vintage ribbons or dynamic mics. By applying gain before it reaches digital, it prevents the overuse of onboard digital gain, which can introduce noise and degrade tone. This gives you a clean, rich signal without thinning or distortion, even with long cable runs. Tone-Shaping Controls Tailor your sound with the Warm Lifter's selectable 100Hz high-pass filter and 3kHz high-shelf boost. The high-pass filter helps eliminate unwanted low-end rumble, improving clarity and detail, while the high-shelf boost enhances the upper mids and highs, perfect for brightening up darker mics. These controls ensure that your microphone delivers the best possible sound with the right balance of frequencies. Professional Grade Components The Warm Lifter utilizes an ultra-low noise JFET input and balanced signal path to ensure superior audio fidelity. Its 2.4k Ohm input impedance is perfectly matched to low-output microphones, solving common impedance issues such as signal loss and phase cancellation. With a THD+N ratio of <-107dB and a frequency response of 10Hz “200kHz, it delivers pristine sound quality without distortion or coloration.
