SRA Series Amplifiers

Specifying the right power amp is often easier than finding it.

Ashly’s SRA-Series makes it a snap to get exactly what you

need. Perfect for installations with modest power require-

ments, our SRA-Series utilizes state of the art technology

to create advanced, efficient amplifiers that fit into 1RU and

weigh less than 10 lbs. The SRA-Series amplifiers are convec-

tion-cooled, so there’s little maintenance after the installation,

and no annoying fan noise. Of course you get the reliability,

superior sonic quality and rugged construction you’ve come

to expect from Ashly.

supply and Class-D amplifier circuitry, providing a compact,

light-weight and power-efficient solution. This series includes
