CA502

The Ashly CA502 is a two-channel, high-efficiency Class-D power amplifier designed for professional sound reinforcement and commercial audio installations. Delivering 500 watts per channel into 2-ohm or 4-ohm loads, it combines efficient amplification, flexible connectivity, selectable gain settings, and integrated protection features in a compact 2U rackmount chassis. It also supports bridged operation and 70 V or 100 V constant-voltage systems in the specified configurations.

From The Manufacturer:

The Ashly CA Series was developed to provide high-power amplification with improved energy efficiency and thermal management. The CA502 uses Ashly's proprietary D-MAX™ amplifier technology, active power-factor correction, and SailFlow™ cooling architecture.

Designed for both performance and installation applications, it supports low-impedance loudspeakers down to 2 ohms, provides configurable input gain, and includes switchable high-pass filtering and clip limiting. Its XLR, ¼-inch, and Euroblock connections make it suitable for a range of professional audio systems.
