Warm Audio WA-MPX Microphone Pre-Amp


The Warm Audio WA-MPX microphone preamp is ideal for musicians, producers, audio engineers, and home studio enthusiasts who want to enhance the quality of their recordings using outboard equipment.

The WA-MPX is great for capturing warm clean and transparent tones for vocals, acoustic instruments, and drums, but also delivers an authentic vintage tube-saturated tone to your recordings, allowing you to add warmth, character, and depth.

 

Authentic Reproduction of the Most Revered Tape-Era Tube Mic Preamp

The WA-MPX represents a faithful replication of one of the most acclaimed microphone tube preamps, the legendary AMPEX 351 Tape machine, which played a pivotal role in the creation of rock and roll and radio-friendly hits.

In the era of tape recording, this classic tube preamp was a fixture in the signal chain of successful recordings by renowned artists like Elvis Presley, Les Paul, and Bing Crosby, a sound that continues to captivate today's top musicians.

Equipped with high-quality components, a circuit design that is true to the original, and tape saturation control, the WA-MPX accurately emulates the analogue tone of the original preamp, adding a vintage warmth and colour to your sound.

 

Hi-Pass (80Hz) & Low-Pass (2kHz) Filters to Refine Tone

The 2kHz low-pass filter allows you to further shape and focus your tone, dialling in ultimate midrange warmth & punch. The 80Hz hi-pass filter helps remove unwanted bass noise from unruly sources. By cutting out this unwanted noise, you can improve the overall clarity and quality of your sound.

 

Hand-Inspected & Tested at Warm Audio HQ in Austin, Texas

When it comes to sound quality, every detail matters. The WA-MPX has been carefully inspected at Warm Audio Headquarters in Austin, Texas by trained engineers & musicians with a passion for helping you sound your best.

 

Popular Uses

With three tubes per channel, it delivers a clean and wide-open tube tone that can be dialed in to create natural harmonic distortion and compression as the tubes are pushed. Additionally, users can engage an all-analogue tape saturation by flipping the "Tape Sat" switch. The combination of vintage sound and modern connectivity makes it perfect for use in any hybrid rig.
