Alesis RA500 Power Amplifier

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 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.

"The only trouble I have had with RA500..."

Overall: 4 out of 5 stars
(see rating details)
Sound
Sound is clear, and clean. The volumes can sound scratchy at times if not used for a while.
Features
This amp has 3 inputs types and post terminal outs. No fan, very quite. This was one of the main reason for adding this to my home studio. It has LED metering on the front. I would rather see VU meters.
Quality
I have had repeat issues with the outputs not working on this model.
Value
For a solid state amp, this is a very good performing amp.
Manufacturer Support
The dealer I bought this from keeps a spare on hand for any support issues.
The Wow Factor
Shop around, know your options. Support is important.
