DETAILS

The Cloud CA8125 is an 8-channel Class D power amplifier designed for multi-zone commercial sound systems, delivering 8 x 125W of output power.

Supporting both low-impedance (4Ω) loudspeakers and high-impedance (70V/100V) distributed systems, it is an excellent choice for retail spaces, hotels, restaurants, conference venues, and industrial applications. Its intelligent power-sharing design allows the amplifier’s total 1000W power output to be efficiently distributed across its channels, maximising system flexibility.

With energy efficiency as a priority, the CA8125 features transformerless Class D technology, reducing weight and heat while ensuring reliable performance. The Automatic Power Down (APD) function reduces power consumption to less than 2.5W when idle, and a remote standby/wake-up option allows external control. Advanced protection circuits, including thermal monitoring, DC offset detection, and overcurrent protection, provide safe and stable operation.

Cloud Electronics CA8125 Key Features:

  • 8 x 125W Class D amplification with intelligent power sharing
  • Supports both 70V/100V-line and low-impedance (≥4Ω) operation
  • Balanced line-level inputs with per-channel gain controls
  • Automatic Power Down (APD) reduces idle power consumption to less than 2.5W
  • Remote power control input for external standby/wake-up functionality
  • Variable-speed forced-air cooling for efficient thermal management
  • Comprehensive protection circuits, including thermal, overcurrent, and DC offset safeguards
  • Universal power supply (100-240V AC) for worldwide compatibility

Cloud products have a 5 year commercial warranty as standard
