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 1RU 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.
2-Channel Rack Mount Power Amplifier
The Pure Resonance Audio DA2240 is a compact, simple-to-use dual-impedance 2-channel audio amplifier with a powerful 240 Watts per channel. This rack mount power amplifier adopts a professional high-performance Class-D amplifying circuit and a built-in high-efficiency selectable impedance power supply. With low power loss and heat output, the DA2240 can drive longer and louder.
Dual-Impedance
Unique among audio power amplifiers, each channel has a 4-16 ohms and 70-volt output terminal switch independent of the other channel. Allowing one channel to service a high-impedance (70V) distributed audio system while the other channel can power low-impedance (4-16Ω) speakers. This exclusive function provides contractors with extreme versatility and reduces the number of amplifiers required. Housed in a rugged and lightweight 1RU standard 19-inch industrial chassis design, this rack mount audio amplifier is built for installed sound applications.
