Description

High Quality Distributed Audio

Designed by 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.

Simplicity in Integration

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.

The power cable is detachable for easy service or cable upgrade; the inputs and triggers offer daisy chain outputs. 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.

No worries, No hassle

The 2U rack height and included rack ears make good use of precious rack space. Thermostatically controlled forced air-cooling ensures a long trouble-free service life. Phoenix speaker connection blocks make installation a snap, and wiring further simplified. A bridging feature allows each pair of channels to become a single high power channel.

Award-winning Sonics

The CI 940 is everything you want for high quality distributed audio as NAD is in the top tier of all amplifier brands, consistently winning awards for both performance and value for money. Known for their warm, expansive and intensely musical sound, NAD amplifiers are designed to drive real world speaker loads. The NAD CI 940 will bring out the best performance from any speaker giving you the best possible listening experience. It is also very quiet with inaudible residual noise in no-signal conditions, important when using efficient speakers in small spaces. Energy efficiency is also impressive with <0.5W standby consumption and highly efficient power delivery.
