Description

Crest 7001 Power Amplifier

The Crest Audio 7001 power amplifier is a compact, high-power amplifier designed to meet the stringent needs of professional use in concert touring, high quality sound reinforcement, professional fixed installations, and studio monitoring. A two rack-space amplifier, the 7001 uses forced-air to cool channel heat sinks mounted in a back-to-back tunnel configuration. Stereo, parallel, and bridged mono operating modes can be chosen with a rear-panel Mode Select switch. An actively balanced female XLR input connection and 5-way output binding posts are provided for each channel. The 7001 is fully compatible with the other Crest Audio Professional Series amplifiers, Octal Socket Accessories and the NexSys® computer-controlled audio system.

Features:

  • NexSys-ready
  • Toroidal power transformer
  • Tunnel cooling
  • Dual, variable speed DC fans
  • High thermal mass heat sinks
  • Balanced XLR inputs
  • 5-way output binding post connectors
  • Stereo/Parallel/Bridged Mono mode selector switch
  • Rear panel ground lift jumper
  • Extensive protection circuitry:
    • Clip Limiting prevents speaker damage with gentle gain reduction at clip threshold.
    • IGM (Instantaneous Gain Modulation) monitors connected loads to detect conditions that may overstress output devices, allowing safe operation into nominal 2Ω impedances.
    • AutoRamp gradually increases gain to attenuator setting level when amplifier is turned on.
    • Other protection circuitry: comprehensive thermal management, and short circuit, DC voltage, turn-on/off transient, current inrush and sub/ultrasonic input protection.
  • Ultra-strong, single piece steel chassis
  • Octal Accessory sockets
  • Recessed, stepped attenuators
  • Front panel circuit breaker/power switch
  • Modular construction
