WA-273

If there’s one style of preamp that professional engineers would unanimously agree has defined the tone of pop/rock records for decades, it would most definitely be the venerable 73-style of mic pre.  73-style preamps have been massively used in recording and live applications for many years and are still considered to be the Holy Grail of preamp choices today.  The Warm Audio WA73 Family consists of single and dual channel 73-style preamps (with & w/out EQ), that each pay careful homage to British audio history.

When we at Warm Audio decided to release the WA273 it was imperative that it met vintage expectation in both design and performance.  The tone and sweet character that vintage 73-style mic preamps impart is so unique and familiar, that we had only the pure desire to release sonically accurate reproductions. After years of R&D, careful reverse-engineering, and countless hours of auditioning, the WA273 has been born!

The WA273 is a Desert Island boutique preamp, but it can also be classified as a studio and live work-horse.  Classic 73-style preamps are known for being versatile tools that work with all kinds of microphones from Condenser, to Dynamic, to Ribbon.  The WA273 equally shines on all types of microphones and sources including; vocals, acoustic/electric guitars, bass, drums, percussion, orchestras, keyboards, and even as a tone shaping tool to run partial or complete mixes through.  With 80dB of gain and a fully discrete Carnhill Transformer balanced signal path, there’s no recording, mixing or engineering task that the WA273 can’t handle.
