The Naim Audio CI-NAP 108 is an 8-channel rack-mountable power amplifier ideal for custom integration systems, particularly complementing Focal in-wall and in-ceiling speakers. It supports multi-room audio by controlling multiple speakers across different zones or amplifying up to eight separate streams via local inputs. Key features include independent level controls per channel, signal-sensing auto turn-on with standby after 20 minutes of no signal, temperature-controlled fan for cooling, universal 100-240V power supply, and rack-mount hardware (1.5U). It offers flexible connectivity with 10 RCA inputs (8 local mono unbalanced zone inputs, 2 bus inputs), 10 RCA outputs (including 8 zone outputs and 2 bus outputs for daisy-chaining), 8 pairs of Euroblock speaker connectors for paralleling, and 3.5mm 12V trigger in/out. Designed for home, commercial, maritime, and AV setups, it pairs excellently with the CI-Uniti 102 streamer for complete systems.
