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).

TRA-Series ampliﬁers incorporate a switch-mode-power

supply and Class-D ampliﬁer circuitry, providing an extremely

power-efﬁcient solution. The TRA-Series ampliﬁers include

four models available in two- and four-channel conﬁgurations,

with power ratings of 75W and 150W per channel @ 4 ohms,

70V and 100V.

Features include:

• Convection cooling

• Extremely low noise

• Switchable 120V/240V power supply (internal)

• Extensive protection circuitry

• Front panel:

• Signal level L.E.D.’s on each channel include –24,

-18, -12, -6, -3 and clip alert

• Rear panel:

• Level attenuators for each channel

• Euroblock inputs

• Screw terminal outputs

• Switches to select between two choices of input

sensitivity and HPF frequencies on each channel

• Remote power turn-on/off and adjustable turn-on

delay up to eight seconds.
