Description
The Cloud CXA21K Digital DSP ‘Power’ Amplifier has been designed to provide configurable, consistent and reliable high performance audio power amplification for residential, commercial and entertainment applications.
This CXA21K amplifier is full rack width, with a 2U format power – capable of driving both conventional low impedance (Lo-Z, 2Ω to 8Ω) loudspeakers and high impedance (Hi-Z, 70V/100V) transformer coupled loudspeakers.
Provides 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).
Product Features:
- Total System Power = 2000W
- Output Power @ 2Ω: 4 x 500W (SE)
- Output Power @ 100V: 2 x 1000W (BTL)
- Output Power @ 4Ω: 4 x 500W (SE) 2 x 1000W (BTL)
- Output Power @ 8Ω: 4 x 250W (SE) 2 x 1000W (BTL)
