Pure Resonance Audio DA2500 2-Channel Power Amplifier Dual-Impedance 70V 500W

The Pure Resonance Audio DA2500 is a high-performance 2-channel Class-D power amplifier designed for versatile commercial applications. Each 500-watt channel features an independent 70V/4-16Ω switch, allowing for simultaneous operation of different impedances within a single system. This unique dual-impedance capability provides contractors with extreme flexibility, effectively reducing the number of amplifiers required for complex installations.

Housed in a compact 1U 19-inch industrial chassis, this rack-mount amplifier utilizes a professional high-efficiency switching power supply that delivers 85% efficiency with minimal heat output. The internal layout is optimized for long-term reliability, featuring automatic cooling fans that maintain operating temperatures below 55 degrees. This ensures stable performance even under heavy loads in demanding environments requiring continuous operation.

Safety and ease of use are prioritized with comprehensive protection circuitry, including high-temperature, overload, and short-circuit safeguards. The intuitive front panel includes dedicated volume knobs and clear indicator lights for signal, peak clipping, and power status. Balanced inputs and outputs utilize detachable Euroblock terminals, making the DA2500 a cost-effective and durable solution for any professional sound reinforcement project.
