Warm Audio WA-2MPX Dual-Channel Tube Microphone Preamp

Ultimate Analog Tone - The Warm Audio WA-2MPX Dual-Channel Tube Microphone Preamp

Warm Audio's The WA-2MPX 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-2MPX 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
• Carefully inspected at Warm Audio Headquarters in Austin, Texas by trained engineers and musicians with a passion for helping you sound your best
