Alto Professional is a live sound and PA equipment brand founded in 2000 by a team of audio engineers, headquartered in Cumberland, Rhode Island. The company operates as a subsidiary of inMusic Brands, Inc., alongside sibling brands such as Akai Professional, Alesis, Numark, and M-Audio. Alto Professional positions itself as a "Live Performance Reinforcement" company, designing tools for both sound engineers and performing musicians at accessible price points.

The brand's product lineup centers on powered loudspeakers, portable PA systems, mixers, and wireless audio solutions. Their speaker offerings include the TS Series (Truesonic) and TX Series of powered loudspeakers, ranging from compact models suited to small venues up to 2500-watt units for larger installations. The TrueMix line of analog mixers — including the TrueMix 500, 600, and 800 FX — combines USB audio interfaces, Bluetooth connectivity, and built-in DSP effects from Alesis for recording, streaming, and live use. The Busker is a battery-powered portable PA weighing under 12 pounds with up to 20 hours of battery life, a built-in 3-channel mixer, and app control. The Stealth Wireless system provides cable-free audio transmission between mixers and active loudspeakers.

Alto Professional's gear is broadly aimed at mobile DJs, solo and small-group performers, houses of worship, schools, and corporate AV setups — markets where portability, ease of use, and value are priorities.
