Ashly SRA-4150 Convection-Cooled 4-Channel Power Amplifier

Ashly SRA-4150: Superior Sound Amplification for Every Venue
The Ashly SRA-4150 Power Amplifier defines reliability and power in audio reinforcement, providing 150 watts per channel at 4 Ohms. This versatile, four-channel amplifier is perfectly suited for both public address systems and studio environments, housed in a compact 1-RU chassis that easily integrates into any rack setup. Designed to drive both 4 and 8 Ohm loads, the SRA-4150 is an ideal solution for venues ranging from intimate performance spaces to expansive conference centers.

Efficient and Quiet Operation
Standout features of the SRA-4150 include its convection-cooled design and Class-D amplifier technology, which ensure efficient operation without the need for fans. This not only reduces the noise output—making it suitable for quiet environments like recording studios and broadcast applications—but also enhances the longevity of the unit by minimizing dust accumulation and mechanical wear.

Advanced Configuration for Optimal Performance
Flexibility is at the forefront with the SRA-4150, which offers selectable dual or bridged mono operation modes to accommodate various speaker configurations. The amplifier is equipped with switchable high-pass filters and selectable gain sensitivity, allowing for tailored audio output that meets the specific needs of any installation.

Robust Power Supply and Safety Features
Ashly's commitment to reliability is evident in the SRA-4150’s robust power supply and comprehensive protection circuitry. Features include output over-current protection, DC output handling, main supply rail over-voltage protection, and temperature monitoring—each ensuring the amplifier operates safely under all conditions. This level of protection guarantees not just performance but peace of mind.

Convenient Controls and Connectivity
Ease of use is enhanced by front panel indicators that provide quick visual feedback on power, standby, protect status, and per-channel clip and signal presence. The SRA-4150’s rear panel hosts Euroblock inputs and screw terminal outputs for secure connections, while the front panel includes level attenuators for precise volume control.
