The Cloud CXA amplifiers provide a tamper-proof, high-quality audio solution with a versatile web application that provides in-depth configuration and control.

The Cloud CXA21K power amplifier has been designed to provide configurable, consistent and reliable high-performance audio power amplification for residential, commercial and entertainment applications.

The CXA21K is in a rack-mountable 2U format and can drive both conventional low impedance (Lo-Z, 2Ω to 8Ω) and high impedance (Hi-Z, 70V/100V) loudspeakers.

It provides four analogue inputs and one stereo S/PDIF digital input for connecting various audio sources.

For outputs, the CXA21K provides a single 2 x 1000W 100V line outputs, and 4 x 500W 2Ω to 8Ω output channels

CXA amplifiers also incorporate automatic power sharing technology that enables power to be shared proportionately as required between pairs of outputs in Lo-Z mode. 

Optional Cloud CDR-3 Wall Panels are available to provide local control where needed.
