Crest Audio - ProTour Series

Crest Audio – ProTour Series

Product Information

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

Innosonix – MA32/D²

The intention behind the Maxx series, which includes the LP², D² and HP² range, is to improve the total cost of ownership when it comes to a multi-channel solution. By offering the highest channel count per rack space in a single unit available on the market—complete with a comprehensive built-in DSP package—we believe we have achieved this intended goal.

Offering various audio-over-IP protocols, including Dante, combined with our industry-leading DSP capabilities (featuring 2048 taps of IIR/FIR filters, 32 points of parametric EQ, and precise delay and limiting per channel) provides integrators with the tools necessary to deliver a large loudspeaker solution with minimal sonic compromise.
The creative flexibility and improved cost performance of the Maxx series make these products extremely powerful tools.

MA32/D² delivers 32x 280W @4 Ω in only 2U of rack space.
