SRA-120 Convection Cooled Amplifier

ARCHITECTS SPECIFICATIONS

SRA-120

The power amplifier, being of two channels, shall deliver a minimum power of

45 watts RMS per channel into 8 ohm loads and 60 watts RMS per channel into 4

ohms. When switched into Bridged-Mono mode, the amplifier shall deliver a total

of 120 watts RMS into 8 ohms. The amplifier shall be immune to damage from

shorted, open, or mismatched loads and shall feature independent thermal protec-

tion, turn on delay, and instantaneous turn-off. The amplifier shall have a gain of

26 dB + .2dB per channel. The input sensitivity shall be selectable between

.775Vrms or .245Vrms via a rear panel switch. Frequency response shall be 20Hz to

20kHz + .2dB. The amplifier shall be stable into any load, including pure capaci-

tors and inductors. Hum and noise shall be at least 100dB below full output and

SMPTE intermodulation distortion shall be less than .01% at full output. To mini-

mize hum and reduce overall weight, the unit shall utilize a toroidal power supply

transformer.

The amplifier shall have rear panel switching for mono or stereo and bridging

modes. The inputs shall be of balanced bridging type with both 1/4" phone and

barrier strip connections located on the rear panel of the unit. A ground lift strap

shall be provided to float the input ground from chassis ground if necessary. An

input jack on the front panel shall be provided for connection of stereo head-

phones. A separate attenuator control for each channel shall also be located on the

front panel. There shall be status L.E.D.'s for each channel on the front panel of

the amplifier to indicate signal present, clip alert, and "protect mode". Power

requirements of the amplifier shall be 350W max, 30W idle @ 120VAC, 50Hz-

60Hz. For use in other countries, the unit shall also be available as a 240VAC

model. The unit shall be one rack space (1.75") high and no more than 10" deep.

The amplifier must be convection-cooled, with large, extruded aluminum heat sinks

with vertically oriented fins located on each side of the unit. The shipping weight

of the unit shall be 20 pounds. The amplifier shall be covered under a full limited

warranty of not less than five years. The amplifier must be made in the USA. The

amplifier shall be the model SRA-120, manufactured by Ashly Audio, Inc. of

Rochester, New York.
