Peavey IPR2 7500 Power Amplifier

The Peavey IPR2 7500 2-Channel Power Amp features an advanced design that makes it lightweight while increasing output power, reliability and thermal efficiency. This amplifier is designed with a resonant switch-mode power supply and a high-speed Class D topology that yields a high audio resolution and efficiency. Advanced technology and extensive protection circuitry allow for efficient operation under difficult loads and power conditions.

The DDT (Distortion Detection Technique) circuitry ensures trouble-free operation into loads as low as 2Ω. DDT protects drivers and ensures that sonic integrity is maintained, even in extreme overload conditions. This amp also features 2-channel independent fourth order Linkwitz-Riley crossovers and a variable-speed fan housed in a lightweight aluminum chassis. The amplifier’s high-efficiency design allows it to operate at very low temperatures without the need for massive heat sinks to cool.

Features:

2-channel independent, fourth-order Linkwitz-Riley crossovers
DDT protection for trouble-free operation into loads as low as 2 Ω
IPR Class D topology
Detented input controls
Combination XLR 1/4″ inputs
4-pole twist lock output connectors
