Warm Audio WA-WL Warm Lifter Inline Active Microphone Preamp

Leave Your Noise Floor Down in the Basement

Like you, City Music’s studio engineers know the struggle of getting ample gain from go-to passive ribbon and dynamic mics while keeping the noise floor low. That’s why they give their mics some help with products like this Warm Audio Warm Lifter, an inline active microphone preamp designed for low-output mics that retains top-quality features for both studio and stage applications. Imagine +26dB of analog gain with true impedance matching plus a 100Hz highpass filter and a 3kHz high-shelf boost to shape your sounds before they even hit the EQ. Additionally, the Warm Lifter features an ultra-low noise JEFT input, balanced input/output signals, and it operates on +48V phantom power. Finally, it’s all housed in a solid, dependable device that is more than road-ready and built proudly in the USA.

True analog gain and impedance matching

The Warm Audio Warm Lifter gives you +26 dB of clean analog gain so that every nuance of your favorite mics is perfectly represented. The Warm Lifter has another trick up its sleeve: it also offers true input impedance matching at 2.4k Ohm. So, not only does the Warm Lifter boost your mic’s signal, but it also acts as a matchmaker between low-output microphones and interfaces or mixers. This beautiful little feature solves common impedance mismatch problems such as phase issues, signal loss, and altered frequency response.

Lift and shape

Not content to simply boost signals like many other inline preamps, Warm Audio outfitted the Warm Lifter with a selectable highpass filter at 100Hz to help you get rid of problematic low end rumble. There’s also a selectable 3kHz high-shelf boost to clarify your upper-mids as well. This 3kHz high shelf boost also wonderfully brings out details from darker-sounding ribbon mics.

Ready to rock the road, studio, or stage

With an ultra-low-noise JFET input, fully balanced I/O signal path, and incredibly durable build quality that’s hand-tested and inspected by expert technicians in Texas, the Warm Lifter is guaranteed to become one of your go-to pieces of gear. It’s ready for the road when you are!
