SRA Series Amplifiers are advanced, efficient single-space amplifiers perfect for installations with modest power requirements. The SRA Series makes it a snap to get exactly what you need and nothing you don’t. Housed in a compact single rack space chassis and weighing only 10 lbs, SRA Series Amplifiers are designed to drive 4 or 8 Ohm loads. Choose from 4 models available in 2 and 4-channel configurations with power ratings of 75W and 150W per channel. The 150W models are capable of driving 25V constant voltage lines directly. Switch mode power supplies and Class-D amplifier circuitry provide an extremely power efficient solution. They are convection cooled, so little maintenance is needed 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.
