Cloud Electronics CA2250 2-Channel Power Amplifier, 2 x 250W, Power Sharing (100V/4/8Ω)
DETAILS
The Cloud CA2250 is a high-efficiency, 2 x 250W Class D power amplifier, designed for commercial and multi-zone audio installations.
With the ability to drive both low-impedance (4Ω) loudspeakers and high-impedance (70V/100V) loudspeaker systems, this amplifier is ideal for applications in retail, hospitality, leisure, and industrial environments. Its advanced power-sharing capability allows the total 500W output to be intelligently distributed across its two channels, providing maximum flexibility in system design.
Built for energy efficiency and reliability, the CA2250 features transformerless outputs, ensuring a lightweight and space-saving design. The Automatic Power Down (APD) mode reduces energy consumption to less than 2.5W when idle, while a remote standby/wake-up function offers external control over power management. The amplifier also includes comprehensive protection features, such as thermal monitoring, overcurrent protection, and DC offset detection, ensuring consistent and safe operation in demanding environments.
