Pure Resonance Audio DA2240 Dual-Impedance 240 Watt Rack Mount Power Amplifier

The Pure Resonance Audio DA2240 is a dual-impedance 2-channel Class-D power amplifier with a built-in high-efficiency selectable impedance power supply. Each powerful 240-watt channel has an independent 70V/4-16Ω switch allowing them to simultaneously use a different impedance, delivering more flexibility in various commercial applications. This high-performance rack mount audio amplifier is a cost-effective solution housed in a standard 1U 19" lightweight chassis. The DA2240 features short-circuit, overload, and overheating protection with cooling fans to provide heat dissipation, maintaining safe operation in environments with long working hours.

• High-performance switching power supply and Class-D type power amplifier provides 85% efficiency with low power loss and heat output.
• Two 240-watt channels (at 70V and 4Ω) with 70-volt and 4, 8, or 16-ohm output switches.
• Unique dual-impedance operation with independent 4-16Ω and 70V output terminal switches enables each channel to use a different impedance simultaneously. The balanced inputs and outputs feature detachable Euroblock terminals.
• Compact, lightweight, yet durable 1 rack unit 19-inch industrial chassis with a clean, intuitive design.
• Automatic cooling fans effectively dissipate heat, ensuring safe and reliable operation even in harsh conditions over extended periods of time.
