The NAD CI 8-120 DSP manages to step up power output for distributed audio systems with demanding speaker loads or extra long cable runs, squeezing all this into a 1u chassis for ultimate rack economy. This 4 zone amplifier is a reliable workhorse that delivers audiophile quality and big power. NAD CI amplifiers will redefine the way you view distributed audio systems.

Full Disclosure Power

 IHF Dynamic Power in bridged mode is 4 x 350 watts per channel @ 4 ohm. To put it simply, the CI 8-120 will drive almost anything you need in your multi-room audio system.

Hybrid Digital Amplification

The CI 8-120 DSP uses a customized version of the proven Hypex UcD output stage to deliver great load invariant power with extremely low distortion and noise floor. Every detail of this design has been carefully executed to bring out the best possible performance. 


The CI 8-120 is network ready for simple set up, via the custom WebUI. This allows fast set up, of inputs & outputs, setting gain, stereo/mono and bridging of channels, creation of DSP profiles using the 5 band Parametric EQ, plus high and low pass filters to allow the dialing in of the audio in each zone and optimize performance.
