SRA Series Amplifiers
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. Perfect for installations with modest power require-
ments, our SRA-Series utilizes state of the art technology
to create advanced, efficient amplifiers that fit into 1RU and
weigh less than 10 lbs. The SRA-Series amplifiers are convec-
tion-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 SRA-Series amplifiers incorporate a switch-mode-power
supply and Class-D amplifier circuitry, providing a compact,
light-weight and power-efficient solution. This series includes
four models, available in two- and four-channel configurations,
with power ratings of 75W and 150W per channel @ 4 ohms.
Features include:
• Convection cooling
• Extremely low noise
• Switchable 120V/240V power supply (internal)
• Extensive protection circuitry
• Front panel:
• level attenuators for each channel
• 2-channel versions have a stereo headphone jack
• Signal present and clip alert status L.E.D.’s
• Rear panel:
• Euroblock inputs
• Screw terminal outputs
• Switches to select between two choices
of input sensitivity, HPF frequencies and normal
or bridged mode on each channel
• Remote power turn-on/off and adjustable turn-on
delay up to eight seconds.

Ashly’s TRA-Series expands on the SRA’s concept of “the
right amp for the job.” As with the SRA-Series, these 2RU
amplifiers utilize our state of the art technology and
advanced engineering to produce highly efficient amplifiers
that are convection cooled, so there’s little maintenance after
the installation and no annoying fan noise. The main differ-
ence between SRA and TRA is that the TRA-Series amplifiers
move level controls to the back, give you expanded meter-
ing, and provide low impedance and transformer coupled 70V
and 100V outputs simultaneously (output transformers are
internally mounted).

-18, -12, -6, -3 and clip alert
• Rear panel:
