Know before you buy
The WA73-EQ is designed to replicate the classic 'British' sound, known for its thick, punchy, and harmonically rich character. Thanks to the discrete Class A circuitry and custom Carnhill transformers, it adds a distinct weight and warmth to signals that digital interfaces often lack.
Yes, 80 dB of gain provides plenty of headroom to drive even the most demanding low-output ribbon and dynamic microphones. You will have more than enough clean gain to capture quiet sources without needing an external inline preamp.
The induction coil EQ uses physical inductors to shape the frequency response, which provides a musical, natural-sounding curve that is difficult to replicate digitally. It is designed for broad, tonal sculpting rather than surgical correction, making it ideal for adding 'air' or 'weight' during the tracking process.
Absolutely. The unit features a front-panel jack input that allows you to plug instruments directly into the preamp, utilizing the high-quality transformer circuitry to add character to your DI signal.
No, the WA73-EQ features an integrated power supply, meaning it connects directly to a standard power outlet with a standard IEC cable. This keeps your rack setup cleaner and avoids the clutter of external power bricks.
Yes, the WA73-EQ is built in a standard 19-inch, 1U rack-mountable chassis. It is designed to fit perfectly into any professional studio rack alongside your other outboard gear.
