Warm Audio WA-WL Warm Lifter – compact inline microphone preamp designed for low-output dynamic and ribbon microphones. It delivers clean analog gain before the signal reaches your interface or mixer, avoiding excessive digital amplification.
Clean gain without noise or artifacts
The unit provides 26 dB of transparent analog gain, ensuring proper signal level without stressing interface preamps. The high-impedance balanced JFET input maintains accurate frequency response and minimizes noise when working with low-output microphones.
Built-in tone shaping
A switchable 100 Hz high-pass filter removes unwanted low-frequency rumble, while a 3 kHz high-shelf boost enhances presence and clarity. This allows faster workflow and reduces the need for additional EQ processing in the recording chain.
