Description

The Pure Resonance Audio DA2500 is a dual-impedance 2-channel Class-D power amplifier with a built-in high-efficiency selectable impedance power supply. Each powerful 500-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 DA2500 features short-circuit, overload, and overheating protection with cooling fans to provide heat dissipation, maintaining safe operation in environments with long working hours.

HIGHLY EFFICIENT
High-performance switching power supply and Class-D type power amplifier provides 85% efficiency with low power loss and heat output.

DUAL-IMPEDANCE
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.

POWERFUL
Two 500-watt channels (at 70V and 4Ω) with 70-volt and 4, 8, or 16-ohm output switches.

COMPACT SIZE
Compact, lightweight, yet durable 1 rack unit 19-inch industrial chassis with a clean, intuitive design.

WORKS LONG HOURS
Automatic cooling fans effectively dissipate heat, ensuring safe and reliable operation even in harsh conditions over extended periods of time.

SAFEGUARD PROTECTED
High temperature, overload, and short circuit protection with signal, peak clipping, protection, and power supply indicator lights.

2-CHANNEL RACK MOUNT POWER AMPLIFIER
The Pure Resonance Audio DA2500 is a compact, simple-to-use dual-impedance 2-channel audio amplifier with a powerful 500 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 DA2500 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 1U standard 19-inch industrial chassis design, this rack mount audio amplifier is built for installed sound applications.

RELIABLE COMMERCIAL AUDIO PERFORMANCE
The reasonable heat dissipation layout with automatic cooling fans enables the DA2500 to maintain a working temperature lower than 55 degrees assuring reliable, stable operation even under heavy loads, greatly extending the service life of the equipment. This commercial audio power amplifier also provides comprehensive protection circuitry, including overload, overheating, and short-circuit protection. The intuitive front panel for quick, easy configuration features two volume knobs and indicator lights for peak clipping, protection, signal and power supply. Both channels have balanced inputs and outputs with detachable Euroblock terminals. The DA2500 offers a cost-effective solution ideal for commercial installations.
