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. |

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.
