Description
The Ashly SRA-2150 is a 2-channel convection-cooled rackmount studio PA, or power amplifier, housed in a rugged 1RU metal chassis. Offering an output of 80 watts per side at 8 Ohms, it is designed to drive 4- and 8-Ohm loads.
The SRA-2150 incorporates a switch-mode power supply and Class-D amplifier circuitry, providing a power-efficient solution. The low-noise unit features a switchable high-pass filter and selectable gain sensitivity, turn-on delay DIP switches with up to 8 seconds of delay available, and dual or bridged modes of operation.
The SRA-2150 is equipped with a front-panel headphone monitoring output, an internally switchable 120V/240V power supply, extensive protection circuitry, and standard Euroblock inputs along with screw terminal outputs.
