Crest CA18 Amplifier

CREST AUDIO CA18 Professional Power Amplifier

The Crest Audio CA18 professional power amplifier is designed to achieve unsurpassed sonic performance and long-term reliability – even when operating under extreme stress - in touring or fixed installation applications. The Crest Audio CA18 amplfier provides high power output coupled with true clarity, and is well-suited for high-powered subwoofers and passive full range systems.

Absolute sonic accuracy is the hallmark of every Crest amplifier. Bass is solid and defined to the limits of audibility, with ample current reserves delivered by an “over-engineered” power supply and advanced Class H circuitry. Wide-bandwidth output devices assure detailed, transparent high frequency response. And, thanks to Crest’s exclusive IGM circuit, the Crest Audio CA18 amplifier will drive 2 Ohm loads safely without compromise in performance.

The Crest Audio CA18 amplifier is built exclusively in Crest’s own USA manufacturing facility, with internal components selected for premium quality and proven durability. Each modular subassembly is pre-tested, and the assembled CA18 amplifier receives a rigorous “hot room” burn-in before thorough final checkout on precision test equipment.

CREST AUDIO CA18 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 or Speakon™ connectors
    (market dependent)
  • External switches for stereo/parallel/bridged mono mode,
    Pin 2/3 hot (+), ground lift, and gain/input sensitivity
  • Recessed, stepped attenuators
  • Front panel circuit breaker switch
  • Modular construction
  • Five-year warranty*
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 2 Ohm 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.
