Crest CA9 Amplifier
CREST AUDIO CA9 Professional Power Amplifier
The Crest Audio CA9 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.
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 output
circuit design. Wide-bandwidth output devices assure detailed, transparent high
frequency response. And, thanks to Crest’s exclusive IGM circuit, the
CA9 amplifier will drive 2 Ohm loads safely without compromise in performance.
The Crest Audio CA9 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
Crest Audio CA9 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.
