BluOS Streaming for AV Integration (Section 1 of 3)
At the core of the CI S2 is BluOS, NAD’s advanced streaming platform developed for reliable, high-performance multi-room audio. BluOS supports high-resolution playback and provides access to a wide range of streaming services, internet radio stations, and networked music libraries. Designed for responsive control and long-term stability, BluOS allows installers to deliver a consistent user experience across single zones or larger distributed audio systems.

Two-Zone Streaming with Flexible System Design (Section 2 of 3)
The CI S2 is designed as a two-zone streaming solution, allowing installers to deliver independent audio streams from a single compact component. Each zone can be assigned its own content, volume, and output path, making the CI S2 ideal for distributed audio systems that require greater flexibility without added hardware. With analogue and digital connectivity supporting a wide range of amplifiers and system topologies, the CI S2 enables efficient zone expansion while keeping system design streamlined and easy to manage.

Compact Form Factor for Custom Installation (Section 3 of 3)
The CI S2 features a compact 1U, 1/3-rack- width enclosure, allowing for 6 stereo zones in a 1u rack space. The CI S2 can be combined with other NAD CI Modular Series devices and mounted in the rack using ChassisLink for simple tool free mounting. This space-efficient design supports clean rack layouts and simplifies installation in projects where space and access are limited.
