Our 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. Rack install is made neat and efficient, thanks to inputs and triggers that offer daisy chain outputs.
Well protected, Energy-saving
The CI 980 voltage is universal, which can be 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 will impress with its energy efficiency.
Award-winning Sonics
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. You will love the way 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.
