Alesis RA150

Alesis’ RA150 power amplifier has long been a favorite choice of musicians, hobbyists and professionals alike. Now Alesis extends the RA’s range throughout the recording and production spectrum with a bold new series of affordable amps in three distinct power ratings.
With their rugged construction, striking good looks – among the first examples of Alesis’ groundbreaking new approach to industrial design – and a long list of features, the new RA series will quickly find a home in project and commercial recording studios, broadcast an post-production control rooms around the world.

Designed for studio use, each RA series amp incorporates advanced convection cooling for heat dissipation. The result is long, stable operation unaffected by heat-related complications, without the added distraction and annoyance of fan cooling. And eliminating the danger of losing hard-to- hear details due to noisy amp performance.
