Cloud Electronics CXA21K

The Cloud CXA21K is a DSP-enabled Class-D amplifier which can drive both low impedance (2Ω to 8Ω) as well as high impedance (70V/100V) loudspeaker circuits.

The CXA21K provides an output of 4 x 500W at 2/4ohms, 2 x 1000W at 4/8ohms (BTL) or 2 x 1000W at 70V/100V line (BTL).

The outputs can be flexibly configured as follows:
2 x stereo Lo-Z zones
4 x mono Lo-Z zones
2 x mono Hi-Z zone
1 x mono Hi-Z zone + 1 x stereo Lo-Z zone
1 x mono Hi-Z zone + 2 x mono Lo-Z zone

The built in web browser / wireless access point enables the amp to be set up, adjusted and controlled remotely via an App or over a network. This access facilitates effortless customisation of even the most detailed audio/voice systems and management of multiple DSP configurations and tuning features, such as multi-zone setup, input mixing, priority and ducking, restriction, input and output EQ, S/PDIF output routing, high-pass filter, speaker management and presets, delay, Wall mounted controller configuration, Sine generator, and much more.

Four analogue inputs are available via RCA Phono and Euroblock style connectors.

The energy efficient Class D design also benefits from auto standby after 15 minutes of no input signal (time adjustable in the App).

The amp can be placed on a table top or mounted into a 19” equipment rack with the included rack ears.

  • 2U, 19” rack mounted chassis
  • Full-matrix DSP configuration via web app (built-in)
  • Hybrid power distribution in both Lo-Z and Hi-Z Powered
  • Power Efficient, Class-D technology
  • Flexible power sharing across output channels (Hi-Z only)
  • S/PDIF digital input/output
  • Configurable GPIO
  • ErP and Energy Star compliant
  • Warranty: 5 Years
