Ashly Audio, Inc. Four-channel Amplifier, 75W/ch @ 4 ohms 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. The SRA-Series utilizes state of the art technology to create advanced, efficient amplifiers perfect for installations with modest power requirements. Four models are available in two and four channel configurations with power ratings of 75W and 150W per channel. SRA-Series of amplifiers are housed in a compact 1RU chassis weighing 10 lbs. or less and are designed to drive four or eight ohm loads. 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. All SRA-Series amplifiers are convection-cooled, so there's little maintenence 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.
