Cloud Electronics CA8125 8-Channel Amplifier

The CA8125 is a high-performance 8-channel Class-D power amplifier delivering 125 watts per channel (1 kW total output) for both low-impedance (4-8Ω) and high-impedance (70V/100V) loudspeaker systems. Designed for commercial installations, it provides exceptional audio clarity, energy efficiency, and flexibility, making it ideal for retail, hospitality, leisure, and corporate environments.

Each channel can be configured independently, allowing tailored zoning, routing, and power distribution to suit different spaces or speaker loads. The amplifier's transformerless design ensures clean, efficient performance with minimal distortion, while Automatic Power Down (APD) reduces power consumption to less than 2.5W in standby mode.

Built with reliability in mind, the CA8125 features comprehensive protection circuitry including thermal, DC, and overcurrent safeguards, plus variable-speed forced-air cooling for optimal performance. Its universal 100-240V power supply, remote standby control, and compact Class-D design make it a powerful and dependable choice for any multi-zone professional sound system.
