SRA Series
Architect & Engineering Specs


SRA-2075

The two-channel power amplifier shall deliver a minimum power of 40 Watts RMS per channel into 8 Ohm loads and 75 Watts RMS per channel into 4 Ohm loads with all channels operating. When switched into bridged-mono mode, the amplifier shall deliver at least 150 Watts RMS into an 8 Ohm load. The power amplifier shall have Euroblock input and output connectors and 
a TRS headphone connector on the front panel. It shall have balanced analog inputs and a selectable 80Hz high-pass filter. The power amplifier shall have a 26db/36dB input sensitivity switch and remote standby. It shall include a turn-on delay function of up to 8 seconds. The output circuitry shall be Class D, convection cooled with a frequency response of 20Hz to 20KHz ±1.0dB. Signal-to-Noise shall be greater than 100dB unweighted. The front panel shall provide the status of power, standby, protect, signal level and clip. The amplifier shall mount in a standard 19 inch rack using one space (1.75” high) and weigh 9 pounds. 

The power amplifier shall be an Ashly model SRA-2075



SRA-2150

The two-channel power amplifier shall deliver 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 shall deliver at least 300 Watts RMS into an 8 Ohm load. The power amplifier shall have Euroblock input and output connectors and 
a TRS headphone connector on the front panel. It shall have balanced analog inputs and a selectable 80Hz high-pass filter. The power amplifier shall have a 26db/36dB input sensitivity switch and remote standby. It shall include a turn-on delay function of up to 8 seconds. The output circuitry shall be Class D, convection cooled with a frequency response of 20Hz to 20KHz ±1.0dB. Signal-to-Noise shall be greater than 103dB unweighted. The front panel shall provide the status of power, standby, protect, signal level and clip. The amplifier shall mount in a standard 19 inch rack using one space (1.75” high) and weigh 9 pounds.
