Back in the day, engineers used to rig up a cheap transistor radio to play back mixes to see how they would sound when broadcast. Then along came the ubiquitous Aurotone, perhaps the first dedicated monitor designed to sound like shit and reveal how a track would sound on a cheap music centre. Now reissued, Aurotones have competition in the form of the active Avantone monitors, self-powered cubes invaluable for checking how mixes will sound on radio or television. Featuring a single small full range speaker with a built-in amp, Avantones have become a ‘must-have’ ‘go-to’ source for engineers. Cheap, cheerful and portable, they may not be the original but they are arguably the best.
