In Stock, Available Now




The IMS-4 music streamer’s discreet design allows it to be easily incorporated into any custom installation project. And, its slimline form ensures that it occupies just 1U of rack space.

BluOS allows the IMS-4 to stream lossless music at a quality of up to 24-bit/192khz to 4 zones in a home network. Accessed through the app, or one of the many supported integrated control systems, the multiple IMS-4 streamers can be combined to provide up to 64 zones, with each zone able to play together in perfect sync. It can also simultaneously play different streams to separate zones.

The IMS-4 can access millions of Master Quality Authenticated (MQA) recordings using BluOS technology to allow music to be heard exactly as the artist intended, anywhere in the home.

Analogue and digital inputs allow the addition of a cable box or other non-network sources and to make them available in every zone. The IMS-4 even includes a system interrupt to let doorbells and fire alarms be heard.
