The Ashly SRA-4150 four-channel power amplifier delivers a minimum power of 80 Watts RMS per channel into 8 Ohm loads and 150 Watts RMS per channel into 4 Ohm loads with all channels operating. When switched into bridged-mono mode, the amplifier delivers at least 300 Watts RMS into an 8 Ohm load. The power amplifier has Euroblock input and output connectors. It has balanced analog inputs and a selectable 80Hz high-pass filter. The power amplifier also has a 26db/36dB input sensitivity switch and remote standby. The output circuitry is Class D, convection cooled with a frequency response of 20Hz to 20KHz ±1.0dB. Signal-to-Noise is greater than 103dB unweighted. The front panel provides the status of power, standby, protect, signal level and clip. The amplifier mounts in a standard 19 inch rack using one space (1.75” high) and weighs 10 pounds.
Features include: convection cooling, extremely low noise, extensive protection circuitry, euroblock inputs and screw terminal outputs. 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.
