Peavey Electronics announces that its new IPR DSP Series of power amplifiers will be the first amplifiers to use the acclaimed Waves MX5010 semiconductor. The Waves MX5010 features such proprietary Waves technologies as MaxxBass Bass Extension, MaxxTreble High Frequency Enhancement, 7-Band Paragraphic MaxxEQ, MaxxStereo, MaxxVolume Level Control and more.

With a net weight of just 7 pounds on the lightest model, the Peavey IPR Series uses an advanced design that allows Peavey engineers to dramatically reduce weight while increasing reliability, thermal efficiency and output power (up to 6,000 watts at 2 ohms stable). IPR Series amplifiers are designed with a resonant switch-mode power supply and a high-speed Class-D topology that yields the highest audio resolution and efficiency available. Four DSP-equipped models feature 32-bit, floating-point digital signal processing with program-specific EQ presets that make common sound-reinforcement EQ treatments easy to perform.

The Peavey IPR Series DSP power amplifiers are the first to integrate Waves technology, in particular MaxxBass, which uses psycho-acoustics to create precise harmonic overtones that give the perceived effect of adding low frequencies to the mix. MaxxBass resides in the amplifiers' 32-bit DSP section and can be adjusted from 0 to 100 percent.

The Waves MX5010 semiconductor integrates a high performance 24-bit DSP core with pre-programmed MaxxAudio algorithms for a powerful and cost-effective sound enhancement solution. According to Peavey, providing processing at 24-bits at up to 48 kHz and 100-percent clean bypass guarantees that the MX5010 DSP preserves audio quality at its most pristine form. MaxxVolume will protect the speaker and electrical components from electric surges and speaker fatigue without requiring a dedicated limiter. The unit's Delay function can be used to create programmable speaker arrays and delay towers without an external delay module. MaxxTreble can be used to enhance high frequencies dynamically without "painful" high end. MaxxEQ and MaxxBass can be used for designing efficient and programmable active crossovers for both amplifiers and powered speakers. The MX5010's router section can be used to control levels for multiple speaker outputs, also allowing the user to create presets for various I/O scenarios.

"Integrating MaxxBass into the Peavey IPR Series gives sound companies and engineers significant advantages," says Fred Poole, senior manager of product development at Peavey Electronics. "Because it creates the illusion of adding bass frequencies without physically doing so, MaxxBass allows sound engineers to dial more low-end into a system without adding more power amps, processing and subwoofers."

Tomer Elbaz, general manager of Waves' Audio Semiconductor and Licensing Division, states: "For 44 years, Peavey Electronics has been a cornerstone in the M.I. and pro market sectors. It has been great to work with Peavey's engineering team on this effort."
