Crest Audio CA20 Power Amplifier High-Output Professional Touring PA Amplifier

Crest Audio CA20 Power Amplifier High-Output Professional Touring PA Amplifier

The Crest Audio CA20 Power Amplifier is a high-output professional power amplifier designed for large-scale live sound reinforcement, touring systems, stadium events, and heavy-duty rental applications. Built with Crest Audio’s renowned engineering standards, it delivers exceptional power, reliability, and long-term performance in demanding professional environments.

At the core of the Crest Audio CA20 Power Amplifier is a robust toroidal power transformer and an overbuilt power supply system designed to handle extreme current demands. This ensures stable, clean power delivery even when driving large PA systems or subwoofer arrays at high sound pressure levels.

The amplifier is engineered with massive aluminium heat sinks and dual variable-speed cooling fans, providing efficient thermal management under continuous heavy load conditions. Its rear-to-front airflow design helps maintain optimal operating temperatures during extended performances and touring use.

The Crest Audio CA20 Power Amplifier delivers powerful output across multiple impedance levels, including 1000W per channel at 8 ohms, 1800W per channel at 4 ohms, 2500W per channel at 2 ohms, and up to 5000W bridged at 4 ohms. This makes it suitable for high-demand sound reinforcement applications requiring maximum headroom and output.
