The legendary 1073 wrote the book on characterful mic preamplification and EQ. These venerable circuits 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 WA73-EQ mic/line/instrument preamp. In both design and performance, the WA73-EQ 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 and EQs, 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 WA73-EQ. 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. Boasting weapons-grade build quality with discrete, handwired Class A circuits and top-drawer parts such as UK-made Carnhill transformers and Blore Edwards mil-spec, dual-concentric switch pots, the WA73-EQ has 80dB of gain on tap so you can capture subdued sources with your favorite ribbon mic. Your ribbons and condensers will sound heavenly; you'll even be gobsmacked when you hear how authoritative your dynamic mics sound. Cranking the input stage and backing off the output gain enhances your tracks with tasty vintage-style coloration. Topping off the feature set is an instrument jack, polarity reverse, 48V phantom power, and switchable impedance for tonal variation and to optimally match a variety of microphones.
