The legendary 1073 wrote the book on characterful mic preamplification. This venerable circuit helped define the punchy sound of ’70s rock — and countless recordings and live concerts ever since. Today, this coveted tone can be yours for a song, with the Warm Audio WA273 mic/line/instrument preamp. In both design and performance, the 2-channel WA273 pays homage to the revered British console lineage that started it all. Throughout the audio industry, the 1073 is considered the holy grail of preamps, with a rich, sweet, and bold tonality that’s ideal for making audacious statements with your music. After years of R&D, painstaking reverse-engineering, and countless hours of listening, Warm Audio captured the sonic essence of this classic perfectly in their boutique WA273. With 80dB of gain and a fully discrete transformer-balanced signal path, the sound is a revelation: harmonically rich bottom end, focused midrange, and slightly resonant highs.
With judicious mic selection and placement, drums are larger-than-life; DI bass and keyboards sound massive and synths become trance-inducing; electric guitars soar; vocals rule. Pianos and acoustic guitars are resplendent. Orchestral instruments — strings, woodwinds, brass, and percussion — achieve ineffable lushness and dimension. You can even use the WA273 as a tone-shaping tool to run stems or complete mixes through. Hear what the WA273 can do for your own recordings. It’s transformative.
