The amplifiers shall have internally mounted transformers to provide both 70V and 100V constant voltage. Each channel shall deliver a minimum of 75W or 150W, model depending, to the constant voltage lines. Dimensions of the amplifiers shall be 19"W x 3.5"H x 11.0"D, with a weight of 29.5 pounds. The amplifiers shall utilize a state-of-the-art, efficient, switched mode power supply. The power supply shall operate at either 120 or 240VAC, 50/60Hz. The amplifier shall be convection cooled. The amplifier shall have a selectable input gain of 26dB or 36dB. Frequency response shall be 20 Hz - 20 kHz, +/- 1.0 dB. Hum and noise shall be greater than 98dB and greater than 105dB repectively below full output (20Hz to 20KHz unweighted). Each amplifier channel shall be supplied with an attenuator located on the rear panel. Each input shall have a fixed high pass filter of 12dB/octave at 80Hz. The inputs shall be active balanced design, with an impedance of 20K ohm with a maximum input level of +21dBu. Input connections shall be 3-pin Euroblock. Output connectors shall be a screw terminal strip with safety cover. The amplifiers shall have front panel indicators for power, standby and protect. Each channel shall have a 6-step signal level meter indicating -24db, -18dB, -12dB, -6dB, -3dB and clip alert. The amplifier shall have built in protection for Output OverCurrent, DC Output, Main Supply Rail Overvoltage, Chassis Internal Temperature, Inrush Limiting and Mains Fuse. The amplifer shall have a 2-pin Standby Connector to provide for remote standby switching with a 0.5 second turn-on delay. Additionally, the amplifier shall have user selectable Delay Switches to provide incremental turn-on delay when the Standby connector is used. The switches shall be additive, providing as much as 7.5 seconds of delay to the 0.5 second Standby delay. The amplifier shall have a cTUVus safety listing and shall be in compliance with FCC, CE and RoHS regulations. The amplifier shall be covered under a full limited warranty of not less than five years. The amplifier shall be an SRA-Series two-channel model, manufactured by Ashly Audio, Inc. of Rochester, New York.
