High-Density Rack-Mount Power for Custom Multi-Room & Architectural Audio Systems

Designed specifically for custom integration in homes, commercial spaces, and marine installations, the Naim CI-NAP 108 is an 8-channel, rack-mountable power amplifier engineered to drive architectural loudspeakers without sacrificing Naim’s signature musical refinement.

Occupying a compact 1.5U chassis, the CI-NAP 108 provides robust amplification for up to 8 independent audio streams or high-density speaker zones, making it the ideal partner for the CI-Uniti 102 network streamer or high-end AV processors.

Key Features & Performance Innovations

High-Power Audiophile Output: Delivers 150 Watts RMS per channel into 8 Ohms and 260 Watts RMS into 4 Ohms, effortlessly driving demanding in-wall, in-ceiling, or outdoor speakers.

Versatile Routing Architecture: Equipped with 10 stereo RCA analogue inputs (8 dedicated local zone inputs plus 2 global L/R bus inputs) and 10 loop-out RCA outputs for easy daisy-chaining to additional power amplifiers.

Simplified Euroblock Wiring: Features dual Euroblock speaker terminals per channel, allowing fast, parallel speaker wiring in custom installation racks.

Precise Gain Calibration: Includes independent rear-panel gain level controls for each zone, ensuring ideal volume matching across various room sizes and speaker sensitivities.

Energy-Efficient Operation: Employs music-sensing auto-standby functionality (engaging after 20 minutes of silence) to drop power draw down to just 0.5 Watts.

Temperature-Controlled Cooling: Features a near-silent internal fan system designed to maintain thermal stability in enclosed rack environments.
