Ashly Sra-2075 User manual

Specifying the right power amp is oen easier than

nding it. Our SRA Series makes it a snap to get exactly

what you need.

SRAs are advanced, ecient ampliers perfect for

installaons with modest power requirements. Housed

in a compact single rack space chassis, and weighing

only 10lbs, they're designed to drive 4 or 8 Ohm loads.

Choose from 4 models available in 2 and 4-channel

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

per channel into 4 Ohms. The 150W models are

capable of driving 25V constant voltage lines directly.

Switch mode power supplies and Class-D amplier

circuitry provide an extremely power ecient soluon.

They are convecon cooled, so lile maintenance is

needed 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.

SRA Features:

• Convecon cooling

• Extremely low noise

• Extensive protecon circuitry

• Level aenuators for each channel

• Signal present and clip alert status LEDs

• Selectable input sensivity

• Defeatable 80Hz HPF

• Euroblock inputs/outputs

• Stereo or bridged mode switch per channel pair

• Remote stand-by control

• Adjustable turn-on delay up to 8 seconds

• Stereo headphone jack (on 2-channel models)

• Safety/Compliance:
