Ultimate Analog Tone - The Warm Audio WA-MPX Single-Channel Tube Microphone Preamp

Warm Audio's WA-MPX is an authentic reproduction of the most revered microphone tube preamp that pioneered the birth of rock ‘n’ roll and radio-ready hits. With premium components and true-to-original circuit design, WA-MPX authentically delivers the iconic analog warmth and tape-era tube tone that is still chased by today’s modern artists.


  • Based on the 351-style tube preamplifier found in American tape machines
  • Impressive 300v of raw power and 90 dB of tube gain, WA-MPX achieves clean gain & 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 that provide compression, saturation, and non-linear frequency response for authentic tape-era reel-to-reel sound at 15IPS
  • 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
