It had to happen sooner or later. Leave it to the innovators at Warm Audio to build a microphone preamp based on the tube electronics of the iconic American professional tape machine that recorded countless radio-ready hits during the golden age of analog. From the rock pioneers of the ’50s and ’60s to today’s sound-savvy artists, the legendary “351” has been the secret sauce in the signal chain that delivers the vintage-flavored warmth and color we all seek in our own recordings. The Warm Audio WA-MPX 1-channel tube mic/line/instrument preamp incorporates an original-spec circuit design, authentically reproducing the coveted analog sonics of the original. Handwired and hand assembled using only premium, all-discrete components, including custom-wound, original-spec large-core CineMag USA transformers, the WA-MPX serves up instant “sounds-like-a-record” punch for tracks that blast right out of the speakers. But there’s so much more to this amazing preamp that makes it indispensable to modern hybrid studio workflows.
