Cloud Electronics CA8125 8-Channel Power Amplifier, 8 x 125W, Power Sharing (100V/4/8Ω)
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.
