Ashly Tra-2075 User manual

The TRA Series expands on the SRA’s mantra of “the

right amp for the job.” These 2 rack space ampliers

ulize our advanced, ecient ampliers perfect for

low impedance and transformer isolated 25V, 70V or

100V installaons with modest power requirements.

Choose from 4 models available in 2 and 4-channel

conguraons, with power rangs of 75W and 150W

per channel at 4 Ohms, 70V and 100V. All TRA audio

controls are on the rear panel. A 6-step LED meter for

each channel lets you monitor all levels. TRA ampliers

can drive 4 or 8 Ohm loads and 25V or 70V and 100V

constant voltage lines simultaneously. Output trans-

formers are internally mounted.

The 150W models are also capable of driving 25V

constant voltage lines using the direct coupled

4 Ohm output. TRA Series ampliers incorporate

a switch-mode power supply and Class-D amplier

circuitry, providing an extremely power-ecient

soluon.

All TRA Series ampliers are convecon-cooled,

so there’s lile maintenance aer the installaon,

and no annoying fan noise. Of course you get the

reliability, superior sonic quality and rugged

construcon you’ve come to expect from Ashly.

TRA Features:

• Convecon cooling

• Extremely low noise

• Internally mounted constant voltage transformers

• Extensive protecon circuitry

• 6-Step signal level and clip LEDs

• Level aenuators for each channel

• Euroblock inputs/outputs

• Selectable input sensivity (voltage gain)

• Remote stand-by control

• Adjustable turn-on delay up to eight seconds

• Safety/Compliance: TUV, CE, FCC, RoHS
