Power amplifiers is designed with resonant switch-mode power supply and high-speed class D topology that yields highest audio resolution and efficiency available. This revolutionary amplifier offers sonic superiority and unsurpassed reliability for which Peavey is famous, in an extremely efficient and lightweight design. Advanced technology and extensive protection circuitry allow operation with greater efficiency into difficult loads and power conditions. DDT (distortion detection technique) circuitry ensures trouble-free operation into loads as low as 2 ohms. DDT protects drivers and ensures that sonic integrity is maintained, even in extreme overload conditions. IPR’s high-efficiency design allows amplifier to operate at very low temperatures and does not require massive heat sinks to cool. Although IPR amplifier is simple to operate and housed in an ultra-strong, ultra-lightweight chassis, improper use can be dangerous. This amplifier is very highpowered and can put out high voltages and sizable currents at frequencies up to 30kHz.
