Alta Moda Audio is a boutique American manufacturer of 500 Series studio gear, with products hand-built in the USA. The company's lineup centers on four modules: the AM-30, a fully discrete Class-A transformerless microphone preamp that moves from clean to saturated tones as it's pushed; the AM-25, a four-band parametric equalizer; the Hippo, a VCA-based stereo bus compressor; and the Unicomp, a dual-mono compressor with an unusual gain cell and sidechain topology.

The AM-30 is notable for its socketed discrete op-amps (DOAs), allowing engineers to swap in alternatives such as the API 2520 to change harmonic character without soldering. Alta Moda's units have picked up a following among engineers working in 500 Series racks who favor Class-A discrete designs and tone-shaping flexibility over sterile transparency, and the gear is sold through pro-audio dealers including Vintage King, Alto Music, and Sound Pure.

Alta Moda has 6 products cataloged on Equipboard, including Effects Processors and Preamps. Their gear is featured by 3 artists, with the strongest followings in Electronic and Hip Hop. Notable users include Deadmau5, Eminem, and Robert Babicz.
