Description



The Ashly SRA-4075 is a 4-channel convection-cooled rackmount P.A. or studio power amplifier housed in a rugged 1RU metal chassis, offering an output of 40 Watts per channel at 8 Ohms, designed to drive 4 and 8 Ohm loads.


 


The SRA-4075 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-4075 is equipped with an internally switchable 120V/240V power supply, extensive protection circuitry, and standard Euroblock inputs along with screw terminal outputs.
