Cloud CXA21K 4-Channel Digital Power Amplifier, 4x 500W @ 4 Ohms or 100V Line

The Cloud CXA21K 4-Channel Digital Power Amplifier has been designed to provide configurable, consistent and reliable high performance audio power amplification for residential, commercial and entertainment applications.
The CXA21K amplifier is full rack width, 2U 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. They provide four analogue inputs, one stereo S/PDIF digital input, and either two or four outputs (Lo-Z mode), or one or two outputs (Hi-Z or Lo-Z BTL mode).
