The Cloud CA Series is a range of versatile multi-channel audio power amplifiers of advanced design, able to drive low impedance loudspeakers, or high impedance (100 V-line or 70 V-line) loudspeaker distribution systems directly. They are ideal for sound reinforcement applications in the retail, leisure, hospitality, commercial or industrial sectors.
Model CA2250 can deliver a maximum of 500 W of audio power, which may be similarly shared between its two channels.

Particular design attention has been paid to the amplifiers’ energy efficiency. The Class D output stages dispense with line output transformers, and consequently offer great savings in weight and size over earlier designs. An automatic, two-stage power-down feature (APD) resulting in power consumption of less than 2.5 W. The amplifiers also include a remote standby/wake up function, enabling them to be placed into standby mode - and subsequently powered up again - by a simple external contact closure. The APD feature can be disabled by a rear panel DIP switch.
 
Safety features of the design include output DC detection, overcurrent protection, and thermal monitoring. A switch on delay provides loudspeaker protection at power-up. All models use variable–speed forced-air cooling.
