Product Overview
The Ashly SRA-Series of amplifiers incorporates switch-mode-power supplies and Class-D amplifier circuitry, providing an extremely power-efficient solution. Four models in each series are available in two and four channel configurations with power ratings of 75W and 150W per channel. Features include: convection cooling, extremely low noise, an internally switchable 120V/240V power supply, extensive protection circuitry, euroblock inputs and screw terminal outputs.
SRA-Series amplifiers are housed in a compact 1RU chassis weighing only 10 lbs. and are designed to drive four or eight ohm loads. Front panel features include: level attenuators for each channel, signal present and clip alert status LEDs for each channel. Rear panel features include: rear panel switches to select between two choices of input sensitivity, HPF frequencies and normal or bridged mode, remote power turn-on/off and adjustable turn-on delay up to eight seconds. Two-channel versions have a stereo headphone jack located on the front panel.
