Cloud Electronics CA2500 2-Channel Power Amplifier, 2 x 500W, Power Sharing (100V/4/8Ω)
DETAILS
The Cloud CA2500 is a high-performance, 2 x 500W Class D power amplifier designed for professional multi-zone audio installations.
Capable of driving both low-impedance (4Ω) loudspeakers and high-impedance (70V/100V) loudspeaker systems, it offers flexibility for a wide range of applications, including retail, hospitality, commercial, leisure, and industrial environments.
Engineered for efficiency and reliability, the CA2500 features transformerless outputs, ensuring a lightweight yet powerful design. An Automatic Power Down (APD) mode reduces energy consumption to less than 2.5W when idle, while a remote standby/wake-up function provides external control for power management. The amplifier also integrates essential protection features, including thermal monitoring, overcurrent limiting, and DC offset detection, ensuring longevity and stability in demanding installations.
Cloud Electronics CA2500 Key Features:
- 2 x 500W Class D amplification with selectable 70V/100V-line or low-impedance (≥4Ω) operation
- Per-channel input routing and output mode selection for flexible configuration
- Balanced line-level inputs with per-channel gain controls
- Automatic Power Down (APD) for energy efficiency, with global disable option
- Remote power control input for external standby/wake-up functionality
- Variable-speed forced-air cooling for optimal thermal management
- Integrated protection circuits, including thermal, overcurrent, and DC offset safeguards
- Universal power supply (100-240V AC) for global compatibility
