Crest Audio FA1201

Features

• Crest’s legendary “overbuilt” power supply
• Toroidal power transformer
• Latest generation of high-speed, wide-bandwidth output devices
• Twin tunnel cooling with back-to-front air flow
• Dual, variable speed DC fans
• Massive, extruded aluminum heat sinks
• Balanced XLR and 1/4-inch (TRS) inputs
• 5-Way Binding Post Outputs
• Stereo/parallel/bridged mono mode selector switch
• Ground lift switch
• TourClass® protection circuits:
  • ACL (Active Clip Limiting) prevents speaker damage with gentle gain reduction at clip threshold.
  • IGM (Instantaneous Gain Modulation) monitors speaker 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.
  • TourClass also includes comprehensive thermal management, and short circuit, DC voltage, turn-on/off transient, current inrush and sub/ultrasonic input protection.
• Input sensitivity selection
• Recessed, stepped attenuators
• Front panel circuit breaker switch
• Modular construction
