Details

The Cloud Electronics CX-A450 4 channel amplifier exhibits low levels of noise and distortion, and utilises the highest quality components for outstanding sound quality and rugged durability.

Plug in VCA modules are available for applications where remote level control is required.

In its basic state, the Cloud CXA450 is suitable for low impedance music systems only, but individual channels can be converted to 70V or 100V by installing optional transformer modules. (See related products)

  • 4 channel, 4 x 50W
  • Optional modules for remote level control of any channel, VCA-5
  • Optional equaliser modules for Bose loudspeakers can be fitted to any channel
  • Optional 4 x 40W 70V/100V transformer module - fitted internally -CXL-4160
  • Optional external 40W 70V/100V line transformer module also available CXL-40T
  • Input routing operations simplify terminations when some channels share a signal
  • Comprehensive protection circuitry including dynamic clip protection
  • LED indicators for signal, clip and protect
  • Forced cooling vari-speed DC fan
