SRA-series of amplifiers are housed in compact 1RU chassis weighing 10lbs or less and are designed to drive four or eight ohm loads. 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. All SRA-series amplifiers are convection cooled, so there’s little maintenance after installation and no annoying fan noise. Of course you get reliability, superior sonic quality and rugged construction you’ve come to expect from Ashly.
