Peavey IPR2 2000 Description
The Peavey IPR2 2000 combines powerful audio amplification with a compact, lightweight design. Its advanced Class D topology and resonant switch-mode power supply provide efficient power delivery while minimizing heat generation and eliminating the need for massive internal heat sinks. This makes it a practical solution for mobile DJs, live sound engineers, touring audio systems, and permanent installations where weight and reliability are important.
Designed to handle demanding speaker loads, the IPR2 2000 supports operation down to 2 ohms per channel. Its DDT (Distortion Detection Technique) circuitry helps maintain audio integrity during high-output operation by limiting distortion before it can damage connected speakers. Additional thermal, DC, subsonic, load, and voltage protection circuits contribute to dependable performance under challenging operating conditions.
Each amplifier channel includes an independent crossover with selectable high-pass, normal, and low-pass modes. The 100Hz crossover system allows users to configure the amplifier for different speaker arrangements, including systems with full-range speakers or subwoofers. Front-panel detented attenuators provide repeatable level adjustments, while five LED indicators per channel display active, signal, DDT, temperature, and DC status.
Built with a 0.062-inch-thick aluminum chassis, the amplifier balances durability with portability. Its temperature-dependent, variable-speed 80mm cooling fan adjusts to operating conditions for efficient thermal management. With combination XLR and 1/4-inch inputs and dedicated speaker output connectors, the IPR2 2000 integrates into a wide range of professional sound systems.
