When it comes to the CI 940, NAD’s renowned audio performance combines seamlessly with the flexibility and reliability required for custom integration. Containing 4 channels of low distortion amplification, the CI 940 smoothly delivers the right amount of current for strong, but accurate, bass response. Designed to fit into standard rack units, the CI 940 is completely protected from both short circuit and overheating, and will automatically restore operation once a condition has been rectified. Furthermore, easy integration is guaranteed with the option of either DC trigger or signal-sensing power-on with auto shut-off. Complete with a detachable power cable for easy service and upgrades, the CI 940 provides an expansive sonic experience unique in this category of product.

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.

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.
