New from Peavey Electronics is the IPR DSP Series of power amplifiers, which use the Waves MX5010 semiconductor and in turn offer proprietary Waves technologies like MaxxBass Bass Extension, MaxxTreble High Frequency Enhancement, 7-Band Paragraphic MaxxEQ, MaxxStereo, MaxxVolume Level Control, and more.

The lightweight (7 pounds on the lightest model) IPR amps offer thermal efficiency and high output power (up to 6,000W at 2 ohms stable) despite their reduced size. Designed with a resonant switch-mode power supply and a high-speed class D topology, the DSP-equipped models feature 32-bit, floating-point digital signal processing with program-specific EQ presets for easy EQ tweaking.

Because the amps use the Waves MX5010 semiconductor, they boast 24-bit processing at up to 48 kHz and 100 percent clean bypass. MaxxBass, another added benefit from Waves, uses psycho-acoustics to create precise harmonic overtones that give the illusion of adding bass frequencies without physically doing so. MaxxBass, which can be found in the amps' 32-bit DSP section, can be adjusted from 0 to 100 percent.

The other Waves technologies provide further sound enhancements. MaxxVolume, for example, protects the speaker and electrical components from electric surges and speaker fatigue without requiring a dedicated limiter, while MaxxTreble can be used to enhance high frequencies dynamically, minus the painful high end. Use MaxxEQ to design programmable active crossovers for both amplifiers and powered speakers. And lastly, use the MX5010 semiconductor's router section to control levels for multiple speaker outputs, and in turn create presets for various input and output scenarios.
