Multi-room audio: everything you need to know

Multi-room audio has gone from an expensive fantasy to an affordable reality for pretty much everyone. You no longer need to trail wires or install complex control systems to be able to send your favourite tunes all around your home, controlled by the touch of a button or even just the sound of your voice.

There are more wireless speakers at your disposal than ever, from multi-room specialists such as Bluesound and Sonos, to hi-fi brands like Arcam, Bang & Olufsen and Audio Pro, and tech giants such as Amazon, Apple and Google.

What is multi-room audio?

20 years ago a home multi-room system would have meant a lot of wires (albeit nicely hidden, no doubt) and a fair chunk of cash. High-end custom installers can still offer a top-notch no-stress system, but a more simple, wireless solution is now within the reach of all of us.

Whether you want to start a new music system from scratch or upgrade an existing hi-fi set-up, multi-room means adding one or more (more than one, really...) wireless speakers or wireless devices to your home. These then communicate with each other and can be controlled via an app on your phone, tablet or computer. And now even by your voice. You can then create different rooms of music and either play the same track in unison, or play different music in different rooms.

You can stream music from services such as Apple Music, Spotify and Tidal (provided you have subscriptions to each), play your own music from a network-attached storage device (NAS) or computer, or stream music straight from your phone.

Brands such as Sonos, Pure and Yamaha were some of the first on the multi-room scene, but have since been joined by - well, everyone, with systems from brands as ubiquitous as Bose, Denon, LG, Panasonic, Samsung and Sony, and most recently, the emergence of tech kingpins Amazon, Apple and Google.

What do you need to get started?


It's worth remembering most multi-room speakers can now function as standalone wireless speakers, so you don't have to buy more than one speaker to get started. But it's not really multi-room until you do, though, is it?

Multi-room ranges now include wireless speakers, smart speakers, soundbars, AV receivers, stereo amplifiers and network streamers. There are also components that can connect an existing hi-fi system to a multi-room system, such as the Sonos Connect.

Brands such as Denon, Sony and Yamaha also bring their AV electronics into play, giving their home cinema amplifiers multi-room smarts so they too can join in on the audio streaming action.

How do multi-room systems work?

There are two main ways multi-room systems work: by creating their own mesh network or by using your wi-fi.

Sonos, one of the early pioneers of more affordable, consumer-friendly multi-room systems, forms its own mesh network. This means having initially connected to your home internet, the speakers form their own internal network.

This way, you're not using your home wi-fi when you're streaming music and that tends to make the system more robust.

Most other multi-room systems connect and communicate using your home’s wi-fi network. This means they are reliant on the strength and stability of your network and will have an impact on your network bandwidth.

All the brands mentioned here have their own app that you use to control your music across your multi-room system. Sonos has its excellent Sonos Controller, Bluesound has its BluOs Controller app, Denon its HEOS app, Yamaha uses MusicCast, B&O uses BeoLink, and so on.

In the majority of multi-room cases, you’re tied into a single brand’s ecosystem – brands want you to buy into their systems, after all – so you can’t mix a Sonos speaker with a Bluesound speaker, for instance, to create your multi-room system.

But you don’t have to stick to a single brand if you don’t want to.

Want to mix and match your multi-room system? The options are to either go through the DTS Play-Fi app, or stream via Apple AirPlay 2 or Google's Chromecast built-in streaming options.

Bear in mind that there are two subtle distinctions of multi-room: ones where you can stream multiple sources to multiple devices and rooms (such as Sonos or DTS Play-Fi), or single sources to multiple devices and rooms (AirPlay 2 and Chromecast).

DTS Play-Fi

Instead of creating their own app and multi-room ecosystem, brands can simply sign up to use DTS Play-Fi’s app. DTS Play-Fi is an app that lets you stream music across selected products from manufacturers such as Arcam, McIntosh, Klipsch, Onkyo, Pioneer, Martin Logan, Polk and Rotel. You can stream hi-res music using the app, and mix and match brands to your heart’s content – although DTS recommends a maximum of 32 connected devices before the performance starts to suffer.

AirPlay 2

AirPlay 2 is the long-awaited update to Apple’s proprietary streaming protocol, one that will allow you to stream music from your iOS device (iPhone or iPad) to more than one product. There’s no separate app to download – the iPhone or iPad itself will be the controller and you’ll be able to stream music over your home's network. Along with Apple’s HomePod smart speaker carrying the feature, Sonos, Naim, Libratone, B&W, B&O, and Dynaudio are just a handful of the audio brands that have confirmed AirPlay 2 support in selected products, meaning you should be able to connect different brands' products together to play music.

In each case, you’ll need to download the dedicated app used by each brand to connect and control your system.
