8-CHANNEL AMPLIFIER FOR PROFESSIONAL SOUND SYSTEMS

This eight-channel power amplifier allows custom installation systems to be driven with the sound quality, reliability, and stability for which NAD is legendary. Equipped with state-of-the-art amplifier technology, the NAD CI 8-120 features a continuous power output of 8 x 120 watts into 8 Ω and delivers 4 x 200 watts into 8 Ω in bridged mode. The dynamic power in bridged mode is 350 watts per channel into 4 Ω, allowing the CI 8-120 to drive almost any conceivable speaker configuration required in your multi-room audio system.

However, these hybrid digital amplifiers are not only capable of delivering high current; they are also so compact that they fit into a chassis that occupies only one rack unit. To enable this high level of performance, the CI 8-120 DSP utilizes a custom version of the proven Hypex UcD output stage. It impresses with extremely low distortion and very low noise in the audible range and is specifically designed for the requirements of custom installation, where long cable runs and difficult speaker loads are frequently encountered.

The CI 8-120 DSP is a network-controlled amplifier that the installer can configure and calibrate via a web-based user interface. The interface provides access to multi-channel digital signal processing (DSP), insight into temperature and power status, as well as basic troubleshooting functions such as power cycling, factory resets, and updates.
