Product Description[/b]

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 circuitry. Wide-bandwidth output devices assure detailed, transparent high frequency response. And, thanks to Crest’s exclusive IGM circuit, the CA9 will drive 2½ loads safely without compromise in performance.

Construction and Quality Control[/b]

The CA9 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 CA9 receives a rigorous “hot room” burn-in before thorough final checkout on precision test equipment.

[b]CA9 Features[/b]

• 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 2½ 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

I am sorry to let it go, it is simply an awesome amplifier, awesome sound. Kevin Walker uses one, with his Demeter preamp and schroeder speakers. Check him on youtube.

They cost up to 1340.00 new, but I am letting mine go for £585.00 as I need the money.

please feel free to contact me.
