About Ashly CA Series Power Amp

While the CA Series CA1.04 4-Channel 1000W Class D Power Amplifier is engineered to excel in performance installations such as theaters, school auditoriums, and houses of worship, it's also perfectly suited for commercial installations. This powerful and reliable amplifier can easily handle power-hungry subwoofers, delivering a clean, crisp sound even at 2 Ohms.

The CA1.04 amplifier is equipped with a new D-MAX design, allowing you to run multiple CA amplifiers on a single 20A service. This innovative design, combined with Ashly's proprietary technology, ensures ultimate efficiency and power management. The amplifier's dynamic power factor correction continuously tracks current to maintain accurate monitoring and control, reducing current demand and increasing efficiency when current and voltage are in phase.

One of the standout features of the CA1.04 amplifier is its use of Silicon Carbide (SiC) semiconductors. These cutting-edge semiconductors switch on and off far faster than traditional silicon, resulting in an amplifier that delivers superior audio fidelity and efficiency. This means you can expect a precise, high-quality sound without unnecessary power consumption.

The CA1.04 amplifier also boasts a unique SailFlow architecture for optimal cooling. This innovative design directs airflow over the areas that generate the most heat, ensuring reliable and stable operation even under heavy loads. The amplifier runs cool without the need for heavy heat sinks or noisy fans.

With the ability to operate stably at 0.2 ohms, the CA1.04 amplifier is built to push hard and keep on pushing. It can power up to sixteen 8-ohm loudspeakers from a single 4-channel amplifier and deliver 70V and 100V power with no reconfiguration required. The amplifier also offers both XLR and Euroblock connectivity, making it a versatile choice for any setting.

In summary, the CA Series CA1.04 4-Channel 1000W Class D Power Amplifier is a powerful, efficient, and reliable choice for both performance and commercial installations. Its innovative features and superior technology ensure it delivers clean, high-quality sound every time.
