 Single Channel Preamp EQ Processor 

A Single Channel '73 for the Rest of Us

If there is a single preamp-eq that professional engineers would all agree has defined the sound of pop/rock records over the last 50+ years, the venerable 1073 most definitely be it. Massively used in recording and live applications for decades, even today it's still considered to be the best of the best of preamp-EQs. Providing single- and dual-channel re-creations of this classic British preamp (with & without EQ) the members of the “WA73 Family” each pay careful and humble homage to the original circuit.

It was imperative, when Warm Audio decided to develop and release the WA73-EQ, that it pay respectful homage to the legendary British console history, both in design as well as performance. The tone and sweet sound characteristics that the vintage models provide is so unique and familiar that the only desire was to release truly sonically-accurate replicas. Those years of R&D, careful reverse-engineering, and countless hours of auditioning have all brought about the WA73-EQ.

Know as a “Desert Island” boutique preamp-EQ, the WA73-EQ can also be safely classified as a studio and live sound work-horse. The classic 1073 was known for being a flexible tool that could work with all kinds of microphones: Condenser to Dynamic to Ribbon. The WA73-EQ now equally shines when working with all kinds of mics and source types, including: vocals, acoustic/electric guitars, bass, drums, percussion, orchestras, keyboards, and even as a tool for tone shaping to run partial or even complete mixes through. Its 80dB of gain and fully-discrete Carnhill Transformer-balanced signal path all ensure that there's no recording, mixing, or engineering task that the WA73-EQ can’t handle.

Hand-Wired, Hand-Assembled

Just like the classic 1073, the WA73-EQ is hand-wired. Those in the know assert that part of the 1073's classic tone can be attributed to its hand-wired assembly. Likewise, the WA73-EQ is classically hand-wired and hand-built – including the PCB components – all populated by hand.
