NAD CI S2 2 Zone Music Streamer

2 ZONE BLUOS NETWORK MUSIC PLAYER

The NAD CI S2 BluOS Streaming Module is designed to bring reliable, high-resolution music streaming into professional custom installation systems with efficiency and control. Built on the BluOS multi-room platform, CI S2 provides access to leading streaming services, internet radio, and local music libraries, all delivered with stable network performance and intuitive control. Providing Hi Res audio for 2 zones, the CI S2 integrates seamlessly into distributed audio systems. Compact, flexible, and purpose-built for integrators, the CI S2 delivers modern streaming functionality with the sound quality and reliability expected from NAD Custom Install.

BluOS Streaming for AV Integration

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

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

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.
