SRA-Series 4075 and 4150 Four-Channel Amplifiers
Architects Specifications
SRA-Series, 4-Channel Amplifiers
The power amplifiers shall consist of two separate models (4075,
4150), being of four channels, and shall deliver a minimum
power of 40 or 80 watts RMS per channel into 8 ohm loads and
75 or 150 watts RMS per channel into 4 ohms depending on the
model being used. When switched into Bridged-Mono mode, the
amplifier in use shall deliver 150 or 300 watts RMS into 8 ohms.
Dimensions of the amplifiers shall be 19"W x 1.75"H x 11.0"D,
with a weight of 10 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 or 105dB below full output
(20Hz to 20KHz unweighted).
Each amplifier channel shall be supplied with an attenuator locat-
ed on the front panel. Each input pair shall have a selectable,
bypassable high pass filter of 12dB/octave at 80Hz, a switch to
select stereo or mono mode and a switch to select dual or bridge
mode.
The inputs shall be active balanced design, with an impedance
of 20K ohm with a maximum input level of +21dBu. Input con-
nections 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, stand-
by and protect. Each channel shall have signal indicators for sig-
nal present and clip.
The amplifier shall have built in protection for Output Over-
Current, 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.
