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 WA273-EQ mic/line/instrument preamp. In both design and performance, the 2-channel WA273-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 WA273-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.
