Pure Resonance Audio DA2240 2-Channel Power Amplifier Dual-Impedance 70V 240W

The Pure Resonance Audio DA2240 is a professional 2-channel Class-D power amplifier designed for versatile commercial audio applications. This high-performance unit features a unique dual-impedance design, allowing each 240-watt channel to operate independently at either 70V or 4-16 ohms via selectable output switches. This flexibility enables contractors to power a distributed audio system and low-impedance speakers simultaneously from a single rack-mounted device.

Engineered for reliability in demanding environments, the DA2240 is housed in a compact 1U 19-inch industrial chassis that minimizes rack space while maximizing output. The internal switching power supply achieves 85% efficiency, significantly reducing power loss and heat generation. Integrated automatic cooling fans and a strategic heat dissipation layout ensure the amplifier maintains a stable operating temperature even during continuous long-term use.

Safety and monitoring are prioritized with comprehensive protection circuitry against short-circuits, overloading, and overheating. The front panel provides intuitive control with independent volume knobs and clear LED indicators for signal, peak clipping, and protection status. Both channels utilize balanced inputs and detachable Euroblock terminals for secure, professional installations in retail, office, or industrial settings.
