Founded in 1969 in London, Allen & Heath is a British manufacturer of audio mixing consoles headquartered in Penryn, Cornwall, England. The company established its reputation early on by building custom quadraphonic mixing consoles for The Who — used during the production of the album Quadrophenia — and the MOD1 mixer for Pink Floyd, which appeared in their concert film Live at Pompeii. Allen & Heath is a subsidiary of the Audiotonix Group.

Allen & Heath's product range spans professional live sound, DJ, and installation markets. Their flagship dLive digital mixing system is designed for touring and broadcast, offering 128 input channels with class-leading 0.7ms latency. The Avantis sits below dLive as a 64-channel platform with twin HD touchscreens, while the SQ series brings 96kHz digital mixing into a more compact format. The Qu series serves as a widely adopted entry-level digital console.

In the DJ world, the Xone series has been a fixture in clubs and festivals for over two decades. The Xone:92 became one of the most iconic club mixers ever made, favored by DJs like John Digweed, Richie Hawtin, and Chris Liebing for its analog warmth and filter design. Its successor, the Xone:96, adds dual USB soundcards and expanded routing. Allen & Heath also produces the CQ series of compact digital mixers and sound management systems for commercial installations.

Allen & Heath has 156 products cataloged on Equipboard, including Mixers, DJ Mixers, and DJ Controllers. Their gear is featured by 173 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Deadmau5, Merzbow, and Richie Hawtin. Allen & Heath's catalog spans the full price spectrum — from entry-level options to high-end flagships.
