Buzz Audio is a boutique professional audio manufacturer based in Blenheim, New Zealand, founded in 1985 by Tim Farrant. The company designs and hand-builds analog recording equipment — microphone preamplifiers, compressors, and equalizers — for recording, mixing, and mastering applications. Farrant's background in electronics and live/studio engineering shaped the company's first product, the True Class A MA-2 microphone preamplifier (later updated as the MA-2.2).

The brand positions itself on original circuit design rather than clones of vintage gear, with an emphasis on through-hole construction and hand assembly. Signal paths across the range frequently incorporate Class A solid state circuitry and Lundahl output transformers. Notable products include the MA-2.2B stereo mic preamp, the QSP-20 four-channel preamp, the REQ-2.2 resonance equalizer, the Zodiak tilt-and-filter EQ, and the SOC-20 stereo optical compressor with mid-side processing.

Buzz Audio also produces a line of 500 series modules, including the Elixir mic preamp, the Essence opto compressor, the Kick diode compressor, and the Tonic equalizer. The products are sold through boutique pro audio retailers internationally and are used in home and commercial recording studios.

Buzz Audio has 8 products cataloged on Equipboard, including Effects Processors, Preamps, and Channel Strips. Their gear is featured by 2 artists, with the strongest followings in Electronic. Notable users include Aphex Twin and Robert Babicz.
