From wireless microphone systems and broadcast headsets through to installed 100V line loudspeakers, this is the full audio side of the Stage Supply catalogue, serving live production, commercial installation and studio work. The range runs across Sennheiser and Audio Technica microphones and wireless, NEXO loudspeakers, Biamp and BSS installation processing, and specialist problem solvers from the likes of Interspace Industries.

The sub-categories follow the signal chain. Microphones / DI covers capture, from lavaliers and capsules to hum-eliminating balance boxes. Analogue Mixing and Digital Mixing Systems split consoles by architecture, Mic Line Mixers and Communications handle rack summing and crew talkback, and PA holds loudspeakers and amplification for both portable low-impedance rigs and 100V line distributed systems such as the Biamp Apart MASK and Optimal Audio Cuboid ranges, with Monitoring and Studio rounding out the chain. Two checks save the most grief: for wireless, confirm the frequency variant before anything else, since GB-band Channel 38 systems can run under an Ofcom shared licence while other bands need coordinated licensing; for installs, establish whether the site is wired for 100V line or low impedance before choosing loudspeakers, because the two are not interchangeable.

Trade accounts and engineer-level advice sit behind the whole category, and most of this gear pairs naturally with the cabling, power and rigging sections elsewhere on the site.
