B400S Four-Zone Stereo Network Music Player

Bluesound Professional B400S – Rackmount Four-Zone Stereo Network Music Player

B400S Overview

The Bluesound Professional B400S is a versatile 4-zone network music player engineered for commercial audio installations. Housed in a compact 1U rack-mountable chassis, it leverages the robust BluOS platform to stream and distribute high-resolution audio content from local storage and a wide array of streaming services, including those tailored for business environments such as SoundMachine, Custom Channels, QSIC, SiriusXM Music for Business, and Tunify.

Each of the four stereo zones operates independently, allowing for distinct content and control per zone. Alternatively, zones can be grouped into user-defined configurations, either within the B400S or across other connected Bluesound Professional devices on the network, facilitating flexible and scalable audio
