Chapter 3 · Bring Audio into Config
Zones, Central Control and Presence
One speaker that plays music is a good start. But customers remember a building where the music follows them, where a shared space plays as one, and where one control manages the whole house. In this lesson, you will connect zones, add central control, add good night functionality and make audio react to presence. This is where audio becomes part of the building.
By the end of this lesson you will be able to:
- Group audio zones so a shared space plays one source, with separate volume in each zone
- Set up central control of all audio in a building
- Program audio to start on its own when someone enters a room
- Turn off all audio throughout the house when the last person goes to bed
The situation
An open-plan kitchen and dining area has speakers at both ends. The customer wants them to play the same music. But while cooking, they want to turn down the kitchen end only.
The customer also wants one control that stops all the music in the house, especially at bedtime. They loved one thing in the show home: the music started on its own when they walked into a room.
These are three different behaviors: grouped zones, central control, good night functionality and presence. You will build all three in this lesson.
Why a shared space needs grouping
In an open space with more than one speaker zone, the zones must not play on their own. Otherwise, two different sources mix in one room, and it sounds wrong. The solution is to group the zones. They share one source, but each zone keeps its own volume.
How you do this depends on the speakers:
- Master and Client speakers: A Client always plays the source that its Master chooses. So the grouping happens automatically.
- Separate Audio Player blocks/zones, or passive speakers: Use an Audio Player Fixed Group to make them play together.
Build an Audio Player Fixed Group
The Fixed Group combines the sound of several Audio Player blocks into one shared experience. This must be done manually as it is not created when using Auto Configuration.
Create Audio Player blocks
Create an Audio Player block for every zone in a shared space. For example, one block for the kitchen and one for the dining area.Insert Audio Player Fixed Group block
Add an Audio Player Fixed Group block on to the programming page.Assign Audio Player blocks
In the Audio Player Fixed Group configuration select the Audio Player blocks you want to link. Now they will always play the same source.Connect Touch to T5
Control the volume for the whole Fixed Group or individual Audio Players by connecting a LOXONE Touch T5 to the T5 input. Volume can also be controlled in the App.Rename Fixed Group block
If necessary, rename the Fixed Group block. Unlike the individual Audio Player blocks, the Fixed Group block is not automatically named.
Control all audio with Audio Central
You can control audio centrally, in the same way as lighting. The Audio Central block controls all linked audio zones at once. With one action, you can stop the music in the whole building, or change the volume in all zones.
Central blocks only have inputs. They pass their commands down to the linked zones. Central blocks must be on their own programing page, and this page must be set as a Central Room type. This makes them appear in the Central tab of the app.
Make audio react to presence
This is the behavior customers remember: they walk into a room, and the music automatically starts playing. There is no switch and no app. This works because the Audio Player block has a presence input, in the same way as the lighting.
To make audio react to presence, simply connect the room's presence sensor to the P input of the Audio Player block. Now, when presence is detected the music will automatically start/resume playback. If no audio was previously played or queued, then the first favorite (Fav) will play.
Add Central Control using Auto Configuration
You can use Auto Configuration multiple times when commissioning or configuring a building. Each time you use it it builds on what was previously done and does not replace the existing configuration.
Follow these steps to update Audio and add Central Control with comfort functions to the existing audio configuration that was done using Auto Configuration.
Start Auto Configuration
In the Tools ribbon menu click Auto Configuration.Select Basic Functions
Click Next twice to get to the Basic Functions screen. Select Audio for the rooms you want to auto configure.Select Comfort Functions
Click Next to get to the Comfort Functions screen. Select Central Functions and Good Night.Finish Auto Configuration
Click Configure and then click Finish once Auto Configuration creates the audio logic for your project.Confirm configuration
Confirm that Auto Configuration has created additional function blocks which add presence logic.Save to the Miniserver
Rename the function blocks as necessary for the visualization and save to the Miniserver.
What the customer controls in the App
In the LOXONE App, the customer can do much more than play and pause. They can:
- Browse playlists, internet radio, Spotify and their own music library
- Group zones together at any time, so the same music plays around the house
- Change the volume of each zone inside the group
- Set a default source for a room
- Play two different Spotify streams in two rooms at the same time
When the system is set up, the customer does not need you for any of this. This is part of what makes a LOXONE audio system easy to live with.
