Warm Audio WA-MPX Single-Channel Tube Microphone Preamp

The Warm Audio 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 and color to your sound.

FEATURES:

• Based on the 351-style tube preamplifier found in American tape machines that pioneered the birth of rock ‘n’ roll & radio-ready hits
• Delivering an impressive 300V of raw power and 90 dB of tube gain, WA-MPX achieves clean gain and powerful volume, that pushes the tubes to saturate just like the most timeless analog gear
• 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
• Discrete analog components provide compression, saturation, and non-linear frequency response for authentic tape-era reel-to-reel sound at 15IPS
• 2 kHz low-pass filter allows you to further shape and focus your tone, dialing in ultimate midrange warmth and punch, while the 80 Hz hi-pass filter helps remove unwanted bass noise from unruly sources
• Carefully inspected at Warm Audio Headquarters in Austin, Texas by trained engineers and musicians with a passion for helping you sound your best
