CREST AUDIO CA2 Professional Power Amplifier
The Crest Audio CA2 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 AB output circuit design. Wide-bandwidth output devices assure
detailed, transparent high frequency response.
The Crest Audio CA2 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 CA2 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.
