Studiomaster is a British professional audio manufacturer established in the 1970s and based in Milton Keynes, England. The company emerged from RSD Hire, an equipment hire business that transitioned into manufacturing, and built its early reputation on high-power PA amplification and road-reliable mixing consoles. Early products like the 800B power amplifier and the 8-4 portable mixing console became common fixtures on the live-sound circuit, and the brand was associated with large-format touring rigs through the 1980s.

Studiomaster's catalog spans analog and digital mixing consoles, power amplifiers, line-array and column PA systems, stage monitors, installation loudspeakers, microphones, studio monitors, and headphones. Product lines include the C6 series recording mixers and the ClubXS range of desktop consoles with Bluetooth streaming and USB playback, alongside DJ-focused and commercial-install products. The brand operates as a partner of Carlsbro, which covers the instrument amplification side of the group.

A separate but related entity, Studiomaster Professional, operates in India (Mumbai) and supplies a parallel line of amplifiers, mixers, loudspeakers, microphones, and installation audio products to the South Asian market.

Studiomaster has 8 products cataloged on Equipboard, including Mixers, Powered Mixers, and Keyboard Amplifiers. Their gear is featured by 5 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Orbital, Andy McCluskey, and Mark Bell.
