If there is one preamp style that professional recording engineers would unanimously agree has defined the sound of pop/rock records for decades, it would definitely be the venerable 73-style of microphone preamps.
73-style preamps have been used massively in recording and live applications for many years and are still considered the “Holy Grail” of preamp selection today. The Warm Audio WA73-EQ is a 73-style single-channel preamplifier and equalizer that pays careful homage to British audio history.When we at Warm Audio decided to release the WA273-EQ, it was imperative that it lived up to vintage expectations in both design and performance.
The tone and sweet character that vintage 73-style mic preamps convey is so unique and familiar that we had only a pure desire to release sonically accurate reproductions.
After years of development, intensive research and countless hours of testing, the WA273 was born!The WA273-EQ shines equally on all types of microphones and audio sources including; vocals, acoustic/e-guitars, bass, drums, percussion, orchestras, keyboards and even as a sound shaping tool to play through partial or full mixes.
With 80 dB of gain and a fully discrete balanced Carnhill Transformer signal path, there’s hardly a recording, mixing or engineering task that the WA273 can’t handle.
