About Ashly CA Series Power Amp

You can rely on the CA Series CA504 4-Channel 500W Class D Power Amplifier for superior performance in professional installations, including theaters, school auditoriums, and houses of worship. This robust amplifier is engineered to handle power-intensive subwoofers with ease, even at 2 Ohms, delivering a performance that outshines amplifiers with double the rated power and cost.

The CA504 is not just for performance spaces. Its 70 & 100V direct-drive capability and a host of integration-friendly features make it a perfect fit for commercial installations. This amplifier is built to withstand high-demand scenarios, delivering long-lasting, loud, and clear audio output.

The new D-MAX design of the CA504 allows you to run multiple CA amplifiers on a single 20A service. This innovative technology combines smart amplifier design, ultra-fast switching power supply with Silicon-Carbide semiconductors and diodes, and intelligent power management for ultimate efficiency. The Dynamic Power Factor Correction feature ensures current and voltage are perfectly in phase, reducing current demand and boosting efficiency.

Unlike traditional silicon semiconductors, the CA504 uses Silicon Carbide (SiC) semiconductors, which switch on and off faster, enhancing both audio fidelity and efficiency. This advanced technology eliminates the "switching loss" associated with traditional silicon, resulting in a cleaner, more precise sound and improved power usage.

The CA504's unique SailFlow architecture ensures efficient cooling. Instead of allowing air to flow randomly, SailFlow directs air specifically over the areas that generate the most heat, keeping the amplifier cool and ensuring reliable, stable operation under heavy loads.

The CA504 is capable of stable operation at 0.2 ohms, and can power up to sixteen 8-ohm loudspeakers from a single 4-channel amplifier. It can deliver 70V and 100V power with no reconfiguration required, and its XLR and Euroblock connectivity options make it versatile for various installations.

In summary, the CA Series CA504 4-Channel 500W Class D Power Amplifier is a powerful, clean, and reliable choice for both performance and commercial installations.
