Monitor Audio Launches The IMS-4 Music Streamer

June 5th, 2020

From the Monitor Audio press release:

Today, Monitor Audio is delighted to officially launch its new IMS-4 Music Streamer. Featuring BluOS™ technology and Apple AirPlay 2, the IMS-4 is a versatile music streaming solution designed for custom install projects requiring premium sound quality. 

BluOS™ technology allows the IMS-4 to stream to four separate zones and its BluOS Controller app offers complete flexibility: streaming from music services, easy access to music libraries and voice control through a smart device. 

Accessed through the app, or one of the many supported integrated control systems, multiple IMS-4 Music Streamers can be integrated with other BluOS devices to provide up to 64 zones of music. 

Each zone can perform together in perfect sync or play different streams to different zones.

Lossless music can be played at up to 24-bit/192kHz to every room in a home network and, through BluOS, IMS-4 can deliver millions of Master Quality Authenticated (MQA) recordings, which captures and recreates the sound of the original studio performance. 

Apple AirPlay 2 provides the IMS-4 with even greater flexibility as Siri allows users to request the track they would like to hear and state the room they would like it to be played in. Like BluOS, Apple AirPlay 2 lets the music be enjoyed separately or in sync throughout the home. 

The IMS-4 music streamer’s discreet design (1U of rack space) ensures it can be easily incorporated into any custom installation project. Analogue and digital inputs allow the addition of a cable box  or other non-network sources and makes them available in every zone. The IMS-4 even includes  a system interrupt to let doorbells and fire alarms be heard. 

Monitor Audio recommends that the IMS-4 is partnered with an installation amplifier such as its  IA150-8C. Integrated with Crestron, Control4 and RTI, the IMS-4 is compatible with other BluOS enabled devices.

Michael Hedges, Monitor Audio’s technical director, said, ‘The IMS-4 is an exciting new addition to our extensive range of industry-leading custom installation solutions. I am sure our customers will love its ease of installation, flexibility and powerful performance.’
