About the Crest Audio CA Series
The Crest Audio CA Series comprises a range of professional power amplifiers, including the CA2, CA4, CA6, CA9, CA12 and CA18, each designed for consistent, stable performance in fixed and mobile sound reinforcement applications. Amplifiers in the range are built at Crest's USA manufacturing facility, with key sub-assemblies pre-tested before final assembly and each unit burned in and tested with precision audio equipment before shipping. All CA Series amplifiers feature Crest's exclusive TourClass protection to safeguard internal circuitry and connected loudspeakers. Cooling is handled by two rear-mounted fans with front-panel exhaust grills, and a combined front-panel AC switch and circuit breaker replaces traditional fusing.
Crest Audio CA Series — buyer FAQs
What is the Crest Audio CA Series and what is it designed for?
The Crest Audio CA Series is a range of professional power amplifiers, covering models CA2, CA4, CA6, CA9, CA12 and CA18, built for fixed and mobile sound reinforcement applications. The range is engineered for high operating efficiency and accurate sonic performance across the full audio bandwidth, including under stressful operating conditions, making it suited to both touring and installed audio environments.
Who makes the CA Series and where does it sit in the Crest Audio range?
Crest Audio is an American professional audio brand founded in the late 1970s and focused on touring and installed sound. Owned by Peavey Electronics since 1999 and operating under Peavey Commercial Audio, the company builds power amplifiers and mixing consoles. The CA Series sits within its amplifier lineup and shares the same advanced circuit topologies that established Crest amplifiers with touring professionals.
What protection and reliability features does the CA Series include?
All CA Series amplifiers incorporate Crest's exclusive TourClass protection, designed to safeguard both internal circuitry and connected loudspeakers. Each unit is burned in and tested with precision audio equipment before leaving the USA manufacturing facility, with key sub-assemblies pre-tested before final assembly. A front-panel combination AC switch and circuit breaker replaces traditional fuse-based protection.
How is cooling handled on a second-hand CA Series amplifier, and what should owners check?
CA Series amplifiers are cooled by two rear-mounted fans that draw air over the heat sinks and exhaust it through front-panel grills. Keeping those front grills clear of obstructions is essential for unrestricted airflow. When inspecting a used unit, confirming both fans spin freely and the grills are unblocked is a straightforward first check for proper thermal management.
What should I look for when buying a used Crest Audio CA Series amplifier?
Check which model in the range the unit is (CA2 through CA18), since the numbering reflects different output levels within the series. Confirm the front-panel AC switch and circuit breaker function correctly and that the cooling fans operate. Rack mounting ears should be intact. Used listings on this page vary by condition and configuration; each carries a 21-day warranty covering major functional faults, and further guidance is in the buying guide at 10kused.com/used-av-equipment-guide/.
