Product Details The WA-MPX is an authentic reproduction of the most revered microphone tube preamp that pioneered the birth of rock ‘n' roll & radio-ready hits. During the golden-era of tape recording, this style of vintage tube preamp became the signature sound in the signal chain of hit recordings including Elvis Presley, Les Paul, and Bing Crosby - and is a sound that is still pursued by today's biggest artists. With premium components, true-to-original circuit design, and tape saturation control, the WA-MPX authentically reproduces all the analog tone of the original to bring vintage warmth &
color to your sound. Features Authentic Reproduction Of The Most Revered Tape-Era Tube Mic Preamp: The WA-MPX is based on the 351-style tube preamplifier found in American tape machines that pioneered the birth of rock ‘n' roll & radio-ready hits. Power & Versatility For A Wider Range Of Analog Tone: Delivering an impressive 300v of raw power & 90dB of tube gain, WA-MPX achieves clean gain & powerful volume, that pushes the tubes to saturate just like the most timeless analog gear. Premium Components & Hand wired Construction For An Authentic Vintage Experience: Hand-assembled with three premium tubes per channel paired with custom-wound true-to-spec USA CineMag transformers, the WA-MPX authentically reproduces all the analog tone of the original. Selectable, All-Analog Tape Saturation: WA-MPX uses discrete analog components that provide compression, saturation, and non-linear frequency response for authentic tape-era reel-to-reel sound at 15IPS. Hi-Pass (80Hz) & Low-Pass (2kHz) Filters to Refine Tone: The 2kHz low-pass filter allows you to further shape and focus your tone, dialing in ultimate midrange warmth & punch. The 80Hz hi-pass filter helps remove unwanted bass noise from unruly sources.
