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 the Alesis RA100 – as well as any other 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.
