The Warm Audio WA73 is a single-channel, Class-A microphone preamp designed to provide up to 80 dB of gain for engineers, producers, musicians, and vocalists in mobile-recording rigs and home, project, and commercial studios. It features custom Carnhill transformers and is wired and assembled by hand to deliver the sound and functionality of classic British 73-style preamps.
Its inputs include balanced XLR and 1/4 TRS jacks and one front-panel 1/4 TS instrument input. Input impedance, polarity, ground lift, and phantom power are switchable. Connect an outboard compressor or equalizer via the 1/4 TS insert send and return jacks. Balanced XLR and 1/4 outputs are fed by an output level control and allow compatibility with most audio interfaces and mixing consoles. The selectable high-pass filter can be set to 50 Hz, 80 Hz, 160 Hz, or 300 Hz for management of unruly bass frequencies.
The WA73 is rack-mountable and occupies 1 RU.
