Crest Audio CA18 Power Amplifier High-Power Professional Touring PA Amplifier

Crest Audio CA18 Power Amplifier High-Power Professional Touring PA Amplifier

At the core of the Crest Audio CA18 Power Amplifier is a heavy-duty overbuilt power supply paired with a high-performance toroidal transformer. This combination ensures stable, high-current delivery, allowing the amplifier to perform consistently even under intense load conditions in demanding sound systems.

The amplifier delivers 950W per channel at 8 ohms, 1700W per channel at 4 ohms, 2400W per channel at 2 ohms, and up to 4800W in bridged mono mode at 4 ohms. This makes it suitable for powering large full-range speaker systems as well as high-output subwoofer arrays in professional touring and installation setups.

Advanced thermal management is achieved through massive aluminium heat sinks and a twin-tunnel cooling system with rear-to-front airflow. This ensures efficient heat dissipation during continuous operation, helping maintain optimal performance during long events and tours.

The Crest Audio CA18 Power Amplifier includes external configuration switches for stereo, parallel, and bridged mono modes, along with ground lift and input sensitivity controls. These features provide maximum flexibility for integration into a wide range of professional audio systems.

Each unit undergoes rigorous burn-in testing before shipment, ensuring long-term durability and reliability in critical live sound environments. Its rugged construction and proven performance make it a preferred choice for rental companies and touring professionals worldwide.
