Crest shows Class D ProTour amps

Crest Audio showed four models of its Class D ProTour Series power amplifiers at ProLight + Sound 2018.

The units are designed for use in portable and fixed installation audio systems and deliver high output power, efficient cooling, onboard DSP, Dante network connectivity, and USB/Ethernet connectivity for monitoring and control.

The four models are:

• 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.

ProTour Series amplifiers have a powerful internal DSP engine with sampling rates of 96 kHz/24bit and high performance 24bit AD/DA converters.
