NAD CI 980 brings a new generation of high performance amplification for custom installation and distributed audio systems. The CI 980 utilizes the latest high efficiency switching amplifier technology and the all-new design is built to be small, light, and very energy efficient, without compromising the superb musical sound quality of NAD. The CI 980 has 8 channels of clean, low distortion power set up in a 4 stereo zone configuration. Boasting 50 watts per channel, the CI 980 is designed to drive low impedance speakers and long wire runs.

Reliable, Flexible, Easy
Reliability, flexibility, and ease of installation of the CI 980 is unsurpassed. It has a very space-efficient design and will fit into standard racking units with rack ears and Phoenix speaker connection blocks. The amplifier is fully protected from short circuit and overheating, and automatically restores operation after a condition is rectified. The CI 980 is incredibly flexible, with selectable local or global inputs and the ability to bridge channels to create a single high-power channel.

No worries, No hassle
NAD’s primary objectives in the CI 980 design were system reliability and simple installation. The 2U rack height and included rack ears make excellent use of precious rack space, while the highly efficient amplifier produces very little heat, allowing multiple CI 980s to be used in a single rack. Thermostatically controlled forced air cooling ensures a long trouble-free service life. Phoenix speaker connection blocks make installation a snap, and a selectable local or global input further simplifies wiring. The bridging feature allows any pair of channels to become a single high power channel, adding to the CI 980’s flexibility.

Efficient With Low Noise and Distortion
Choose between a DC trigger or a signal-sensing turn on with auto shut-off to make integration easy. The signal sensing circuit 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.

Well-protected, Energy-saving
The CI 980 voltage is universal, which is important in marine and avionics installations. The amplifier is fully protected from short-circuiting and overheating, plus operation is automatically restored after the condition is rectified. Indicator lamps for each zone show protection status and amplifier clipping. With <0.5W Standby consumption and highly efficient power delivery, the CI 980 is bound to impress with its energy efficiency.

Award-winning Sonics
When it comes to sound, NAD is in the top tier of all amplifier brands, consistently winning awards for both performance and value for money. The CI 980 offers warm, expansive and intensely musical sound, designed to drive real world speaker loads, not just simple laboratory test loads. The CI 980 brings out the best performance from any speaker for a remarkable listening experience. It is also extremely quiet with inaudible residual noise in no signal conditions, important when using efficient speakers in small spaces. Musical, practical, efficient and reliable, the CI 980 is everything you could wish for high quality distributed audio.
