Alesis RA150 Refrence Power Amplifier
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.
