Specifying the right power amp is often easier than finding it. Ashly's SRA-Series makes it a snap to get exactly what you need.
The SRA-Series utilizes state of the art technology to create advanced, efficient amplifiers perfect for installations with modest power requirements. Four models are available in two and four channel configurations with power ratings of 75W and 150W per channel.SRA-Series of amplifiers are housed in a compact 1RU chassis weighing 10 lbs. or less and are designed to drive four or eight ohm loads.
The 150W models are capable of driving 25V constant voltage lines directly. Switch mode power supplies and Class-D amplifier circuitry provide an extremely power efficient solution.
All SRA-Series amplifiers are convection cooled, so there's little maintenance after the installation, and no annoying fan noise. Of course you get the reliability, superior sonic quality and rugged construction you've come to expect from Ashly.
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.
