The company’s Class D-based amplification products are engineered to meet the demands of portable and fixed installation audio systems.
Crest Audio, part of the Peavey Electronics family of brands, says the ProTour line of amplifiers includes a choice of four models.
Some of the options built into ProTour line of amps include a powerful DSP engine with sampling rates as high as 24-bit/96kHz and high-performance 24-bit analog-to-digital (A/D) and digital-to-analog (D/A) converters.
Crest Audio explains that through the amplifiers’ internal DSP options, professional integrators have the ability to configure and optimize audio systems.
DSP-based configuration options the amps offer include IR HP/LP crossover filters, RMS compressor, parametric equalization (EQ), alignment delays, and white and pink noise generators.
At the heart of the ProTour line of amplifiers is a switch-mode power supply and Class D circuit that incorporates full-bandwidth PWM modulators that facilitate the amps’ operation with built-in circuit protection.
The amps’ clip/limiter function provides output monitoring to prevent speaker damage with “gentle” gain reduction at clipping thresholds, as well as heat dissipation and overheat protection.
Other options built into the amplifiers include user defined parameters, source input selection and loadable presets via the amps’ front-panel LCD screens, and Dante digital audio modules that enable primary and redundant network connectivity with the ability to monitor the products.
The Crest Audio line of ProTour Amplifiers offer a choice of these models:
- ProTour 8004d: 4-channel amp with 2,000 watts per channel into 4 ohms or 70/100-volt direct drive
- ProTour 5002d: 2-channel amp with 2,500 watts per channel into 4 ohms
- ProTour 4004d: 4-channel amp with 1,000 watts per channel into 4 ohms
- ProTour 3003d: 3-channel amp with 1,000 watts per channel into 4 ohms
