SRA Series specifications
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-ef-
ficient solution.
All SRA-Series amplifiers are convection-cooled, so there’s little maintenence
after the installation, and no annoying fan noise. Of course you get the reli-
ability, superior sonic quality and rugged construction you’ve come to ex-
pect from Ashly.
Features include: convection cooling, extremely low noise, an internally
switchable 120V/240V power supply, extensive protection circuitry, euroblock
inputs and screw terminal outputs. Front panel features include: level at-
tenuators for each channel, signal present and clip alert status LEDs for each
channel. Rear panel features include: rear panel switches to select between
two choices of input sensitivity, HPF frequencies and normal or bridged
mode, remote power turn-on/off and adjustable turn-on delay up to eight
seconds. Two-channel versions have a stereo headphone jack located on
the front panel.
