Product Description
The Crest Audio CA12 professional power amplifier is designed
to achieve unsurpassed sonic performance and long-term reliabil-
ity—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 CA12 will drive 2
Ω
loads
safely without compromise in performance.
Construction and Quality Control
The CA12 is built exclusively in Crest’s own USA manufactur-
ing facility, with internal components selected for premium qual-
ity and proven durability. Each modular subassembly is pre-test-
ed, and the assembled CA12 receives a rigorous “hot room”
burn-in before thorough final checkout on precision test equip-
ment.

®
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
Ω
imped-
ances.
-
AutoRamp gradually increases gain to attenuator setting
level when amplifier is turned on.
-
TourClass also includes comprehensive thermal manage-
ment, 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
• Five-year warranty*
