Alesis RA150

A Powerful New Addition To Alesis' Popular RA Series

Alesis' RA100 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.

Popular prices, powerful performance -
Even with the increasing use of powered speakers, many popular speakers and headphones still require external amplification. These new amps are designed to provide more power and better performance at a lower overall cost per watt than even our own RA100 – as well as any other competing models. As a result, they can more closely match the power needs of virtually any passive speaker or studio monitor, offering a significantly better fit for an exceptionally wide range of budgets, applications and customers. And providing a crisp, clean signal for outstanding performance and extended speaker life.

Cool, quiet operation -
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.

The new leaders in affordable studio amplification -
Three new RA series amps – RA150, RA300 and RA500 – providing a bold and powerful answer to the question, "What's next from Alesis?" Combined with our popular RA100, they offer a wide range of high-quality, popularly priced solutions for virtually any – and every – situation.
