The CI 940 represents NAD's newest generation of high performance amplification for custom installation and distributed audio systems. Like many award-winning NAD amplifiers before it, the CI 940 is designed by our Engineer Emeritus, Bjørn Erik Edvardsen. 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 good damping factor.
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. Generous dynamic power gives music a relaxed yet lively quality.
Easy integration is assured by the choice of DC trigger or signal-sensing auto-on with auto shut-off. The CI 940 employs a sophisticated music-sensing circuit to prevent the false triggers common with noisy source components or other types of interference noise like RF leakage or ground loops. Rack install is made neat and efficient, since the inputs and triggers offer daisy chain outputs. The power cable is detachable for easy service or cable upgrade. The amplifier is fully protected from short circuit and overheating and automatically restores operation after the condition is rectified. Indicator LEDs for each zone show protection status.
