Overview
Three Powerful New Additions to Alesis' Already Popular RA Series
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 and broadcast and 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 Alesis' 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.

"No Complaints"
Amp has been working in my home studio with no problems for something like 14 years and still going. I gave 5 for manufacturer support because you have to give a rating, but actually I never needed any.
Did you find this review helpful?
Thanks for your opinion!
