Monitor Audio IMS-4 Music Streamer

Monitor Audio IMS-4 Music Streamer

Four-zone BluOS music streamer with 1U rack design, high-resolution streaming up to 24-bit/192kHz, and custom-install flexibility for serious multi-room audio systems.

The Monitor Audio IMS-4 is built for custom-install projects where multi-room streaming needs to be clean, reliable, and easy to integrate. It is a four-zone music streamer using BluOS, designed to sit neatly in a rack while providing high-resolution music playback, wide streaming-service support, and easy control through the BluOS app or supported automation platforms.

This is not a lounge-room hi-fi streamer in the usual sense. The IMS-4 is aimed at installed audio systems where one box needs to feed multiple rooms, keep the interface straightforward, and still deliver proper audio quality. Monitor Audio also notes that multiple IMS-4 units can be combined to create up to 64 zones, with each zone able to play together in sync or run separate streams independently.

Four Zones from One Rack Unit

A neat custom-install solution for multi-room streaming

The big appeal of the IMS-4 is that it can stream music to four different rooms or areas from a single 1U component. That makes it a strong fit for distributed audio systems where tidy rack space, straightforward control, and efficient zone management all matter.

For the right project, that can simplify the whole system. Instead of piecing together multiple separate streamers, the IMS-4 gives you one install-focused unit that is purpose-built for multi-room audio.

BluOS at the Core

High-resolution streaming with strong app control and broad platform support

Monitor Audio uses BluOS here, which gives the IMS-4 access to lossless music streaming up to 24-bit/192kHz, along with wide service support and app-based control. The published spec list includes Spotify Connect, Amazon Music HD, TIDAL Connect, Deezer, Qobuz, Napster, KKBox, Bugs, Taihe Music Zone, SoundMachine, IDAGIO, and Orastream, as well as internet radio options like TuneIn, iHeartRadio, Calm Radio, Radio Paradise, and Radio.com.

That makes it a serious platform for modern multi-room listening rather than just a basic zone source. Monitor Audio also highlights MQA support, Apple AirPlay 2 compatibility, Alexa voice control, and BluOS compatibility with other BluOS-enabled devices.

Built for Proper Integration

Works with control systems and wider custom-install ecosystems

The IMS-4 is clearly meant to live inside a wider installed system. Monitor Audio lists compatibility with Control4, RTI, Crestron, URC, Roon, and ELAN, while also noting that analogue and digital inputs allow external sources such as a cable box or other non-network devices to be made available across every zone.

It even includes a system interrupt so doorbells and fire alarms can be heard through the system, which is the sort of detail that tells you this product was designed with real custom-install jobs in mind rather than just retail streaming use.

Easy to Pair with Installation Amplifiers

Designed to sit behind the scenes and feed the right amplifier stage

Monitor Audio specifically recommends pairing the IMS-4 with an installation amplifier such as the IA750-4. That makes sense, because the IMS-4 is a source and control component, not a powered all-in-one streamer. Its job is to manage the music, feed the zones, and integrate into the wider system cleanly.

For installers and clients, that means much more flexibility. You can build the amplification side around the room requirements while letting the IMS-4 handle the multi-room streaming side of the job.

The Audio Experts Take

The IMS-4 makes sense when the brief is proper multi-room streaming rather than a collection of pieced-together consumer streamers. It is a smart install product for homes where music needs to be available across several spaces, controlled easily, and integrated properly into a rack-based system.

What we like here is that it has a clear purpose. Four zones from one chassis, BluOS at the centre, proper control-system compatibility, and the ability to work with installation amplifiers all make it a very sensible choice for distributed audio done properly. For the right project, it is exactly the sort of product that keeps the system cleaner, neater, and easier to use.
