CXA4250 power amplifiers has been designed to provide configurable, consistent and reliable high performance audio power amplification for residential, commercial and entertainment applications.

The CXA4250 amplifier is full rack width, 1U format power amplifier that can drive both conventional low impedance (Lo-Z, 4Ω to 16Ω) loudspeakers and high impedance (Hi-Z, 70V/100V) transformer coupled loudspeakers. Full-matrix DSP configuration via built in CXA web app. They provide four analogue inputs, one stereo S/PDIF digital input, and either eight outputs (Lo-Z mode), or four outputs (Hi-Z).

CXA4250 amplifier model output channel counts and power outputs are as follows:
