HIGH QUALITY DISTRIBUTED AUDIO
Designed by our Engineer Emeritus, Bjørn Erik Edvardsen, the CI 940 represents NAD’s newest generation of high performance amplification for custom installation and distributed audio systems. The CI 940 can easily provide the instantaneous peak current required for good bass response by utilizing multiple discrete high power output devices. The power supply features a custom toroidal transformer that maintains very low impedance for lowest noise and amazing damping factor.
Power and Performance
The CI 940 has 4 channels of clean low distortion power set up in a 2 stereo zone configuration. Boasting 35 watts of continuous power per channel, the CI 940 is designed to drive low impedance speakers and long wire runs. Vanishingly low distortion and near absence of noise allow the music to emerge from a ‘black’ background that enhances stereo perspective and allows the subtle details of the music to be heard clearly.
