Warm Audio WA-MPX Single-Channel Tube Microphone Preamp

Warm Audio WA-MPX Single-Channel Tube Microphone Preamp Overview: Tape-Era Tube Warmth The WA-MPX & WA-2MPX are authentic reproductions of the most revered microphone tube preamps that pioneered the birth of rock ‘n’ roll & radio-ready hits.

During the golden era of tape recording, the original 351-style tube preamps were the kings of studio tech delivering pure analog warmth; the signature sound in the signal chain of hit recordings for artists including Elvis Presley, Bing Crosby, Les Paul , Nat King Cole, and Roy Orbison.

An Authentic Vintage Experience The WA-MPX preamps deliver the same sonic signature as their vintage inspiration, imparting high-headroom analog warmth that goes from ultra clean to rude and saturated. Each channel boasts a handwired circuit containing custom CineMag transformers and three tubes that, with the high-gain switch engaged, bring the WA-MPX up to an incredible 90dB of gain.

The WA-MPX not only delivers the sound of a legendary tape-era tube preamp but one of the best values in an all-tube mic preamp on the market today. The classic Warm Audio “tone” control alters the input transformer impedance from 600Ω to 150Ω,, adding “air” or “sheen” to the top end - great for ribbons or “darker” mics.
