TRA-Series Amplifiers

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.
