Crest Audio ProTour Series amplifiers

with integrated DSP and Dante connectivity



Following their recent European unveiling at ISE 2018, Crest Audio will be showcasing their powerful new Class D ProTour Series power amplifiers at ProLight + Sound 2018. Designed to meet the most demanding requirements of portable and fixed installation audio systems, the ProTour Series delivers high output power, efficient cooling, onboard DSP, Dante network connectivity, and USB/Ethernet connectivity for monitoring and control.

The ProTour Series currently comprises four models:

  • ProTour 8004d 4-channel amplifier with 2000w/channel into 4 ohms or 70/100V direct drive
  • ProTour 5002d 2-channel amplifier with 2500w/channel into 4ohms
  • ProTour 4004d 4-channel amplifier with 1000w/channel into 4 ohms
  • ProTour 3003d 3-channel amplifier with 1000w/channel into 4 ohms or 70/100V direct drive

All models incorporate a highly efficient switch mode power supply and Class D circuitry with full bandwidth PWM modulators for ultra-low distortion, high efficiency and superior circuit protection. The clip/limiter function provides output monitoring to prevent speaker damage with gentle gain reduction at clip threshold as well as efficient heat dissipation and overheat protection for uncompromised reliability.

In addition to delivering lashings of power, ProTour Series amplifiers are also capable and sophisticated loudspeaker processors thanks to a powerful internal DSP engine with sampling rates of 96 kHz/24bit and high performance 24bit AD/DA converters. Everything you need to optimize a loudspeaker system is at your fingertips; IIR HP/LP crossover filters, RMS compressor, parametric EQ, alignment delays, white/pink noise and much, much more.

Users can set parameters, select input source and load presets via the convenient front panel LCD touchscreen. A Dante network module enables primary and redundant connectivity to a digital audio network and allows external control and monitoring of the amplifier.
