Warm Audio WA73

The WA73 delivers the classic, thick, and harmonically rich sound associated with vintage British 1073-style preamps. Thanks to the custom UK Carnhill transformers, it adds a noticeable warmth and fullness to signals, making it ideal for vocals, guitars, and bass.

Yes, 80dB of gain is plenty of headroom to drive even the most demanding ribbon or dynamic microphones. You will have more than enough clean gain to capture quiet sources without needing an external inline preamp.

The Tone button changes the input transformer impedance, which alters the frequency response and the way the preamp interacts with your microphone. Engaging it provides a slightly different tonal color, giving you more flexibility to match the preamp to specific microphones.

Absolutely. The unit features a DI input on the front panel, allowing you to plug in guitars, basses, or synthesizers directly. This lets you take advantage of the Class A circuit and transformers to add character to line-level or instrument-level signals.

The high-pass filter is a 4-position sweepable control that allows you to cut low-end frequencies at 50, 80, 160, or 300 Hz. It is a highly effective tool for cleaning up muddy signals or removing unwanted rumble before the signal hits your interface.

No, the WA73 features an internal power supply with a standard IEC cable connection. This makes for a cleaner setup in your rack since you don't have to deal with external 'wall wart' power bricks.
