Add To Wishlist



The Ashly SRA-2075 is a 2-channel convection-cooled rackmount P.A. or studio power amplifier housed in a rugged 1RU metal chassis, offering an output of 40 Watts per side at 8 Ohms, designed to drive 4 and 8 Ohm loads.


The SRA-2075 incorporates a switch-mode-power supply and Class-D amplifier circuitry, providing a power-efficient solution. The low-noise unit features a switchable HPF filter and selectable gain sensitivity, turn-on delay DIP switches with up to 8 seconds of delay available, and dual or bridge modes of operation.


The SRA-2075 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.
