## Long description

The Warm Audio WA73 is a single-channel mic/line preamplifier styled after classic '73 British preamps. It provides a frequency range of 20–20,000 Hz, an input impedance of 1.2 kΩ, and accepts standard microphone and line sources. The unit is powered from 115/230 V at 50/60 Hz and comes in a black finish in a single rack-unit form factor suitable for studio and live tracking of voice and instruments.
Advantages
The WA73 reproduces the tonal characteristics associated with vintage '73-style preamps by combining discrete circuitry with custom Carnhill-style transformers and selected capacitor types in the signal path. Hand-wired and hand-assembled construction aims to retain the wiring practices associated with classic designs. With substantial gain capability and a transformer-balanced output, the preamp is built to deliver a musical, harmonically rich signal that works across a wide variety of microphones and sources.
Suitable for
Vocal recording and tracking
Acoustic and electric guitar preamplification
Bass and drum miking in studio or live settings
Ribbon, dynamic and condenser microphones
Tonal shaping of instrument or mix subgroups

How to use
Connect a microphone or line-level source to the appropriate input and route the output to your recorder, interface, or mixing console. Set gain to achieve a clean, optimal level without clipping; the unit provides ample gain for low-output microphones. Use the preamp as the front end for tracking vocals, instruments, or for feeding a tonal front-end into a mixing chain. Follow standard safety and grounding practices when integrating the WA73 into studio or live systems.
Usage recommendations
For a natural, vintage-inspired character, pair the WA73 with dynamic and ribbon microphones or with condenser microphones when additional warmth and transformer coloration are desired. Adjust input gain conservatively to allow the transformer to impart subtle saturation when needed. Use balanced cabling and proper gain staging to preserve signal integrity.
