CA1.04 4-Channel Power Amplifier

The Ashly CA1.04 is a four-channel Class D power amplifier designed for professional sound reinforcement and commercial audio installations. It delivers 1,000 watts per channel at 2 or 4 ohms and 500 watts per channel at 8 ohms. With direct 70V operation, bridged 100V capability, efficient cooling, and installer-friendly connections, it is suitable for high-output loudspeaker systems and distributed audio applications.

From The Manufacturer:

Ashly's CA Series combines high-efficiency D-MAX Class D amplification with its SailFlow cooling architecture. Designed for demanding performance installations, the series provides high output power, selectable gain, flexible input connectivity, and support for both low-impedance and constant-voltage loudspeaker systems.

The CA1.04 is the four-channel, 1,000-watt-per-channel model in the series. Its features make it suitable for venues such as houses of worship, theatres, auditoriums, stadiums, and commercial installations.
