Install Speaker 10 Master

This active loudspeaker features a woofer with a coaxially integrated tweeter.

It is powered by 24V and connected to an Audioserver or Miniserver Compact via Tree Turbo. Through the Master Client Interface (MCI), it can transmit the audio signal to up to 20 additional Client Speakers. It also supports wireless music streaming via Bluetooth.

For optimal sound, the speaker must be installed in a suitable enclosure or a closed ceiling or wall.

Connect the 24V DC power supply and the Tree Turbo data lines to the speaker as follows:

To a Master Speaker, up to 20 Client Speakers can be connected in a line via the Master-Client Interface (MCI):

The audio signal is transmitted digitally from speaker to speaker. The system compensates for differences in signal transit time and therefore only works with the wiring shown in a linear configuration.
On the MCI data lines, there must be no branching or parallel connection to additional speakers!
When only a few speakers are used, the power lines can also be run in a linear fashion.
When using many speakers in a line, voltage drop becomes the limiting factor. This can be addressed by using wires with a larger cross-sectional area, shorter cables, or additional 24V power lines. It is essential to always connect the grounds of different power lines.

The connection cable must be secured to the metal bridge of the speaker basket with the cable tie for strain relief:

Mounting the Speaker:
Ensure that there are no loose foreign objects in the mounting opening to prevent any background noise.
Insert the speaker into the opening and screw it in place at the front.
The retaining clips will fold out inside and secure the speaker tightly.
Make sure that the speaker fits snugly all around.
Attach the front grille, which is held magnetically.


After connecting and switching on the power supply, the speaker starts in about 30 seconds and is then ready for pairing via Tree Turbo.

Speaker Installation Planning

Loxone Install Speakers require installation in a closed enclosure or a cavity, such as in ceilings or walls, to fully develop their sound volume.

Suitable mounting enclosures for drywall or concrete installation are available in the Loxone Shop.

While a mounting enclosure is not necessarily required for completely enclosed surfaces, speakers must be mounted in a rear mounting enclosure for open surface structures, like acoustic ceilings.

The acoustically necessary volume for installation depends on the speaker size and type:

Speaker Type Minimal volume Recommended volume
Install Speaker 7 7.2l 9l or more
Install Speaker 10 14.5l 18l or more
Install Sub 10 18l 22.5l or more

Larger enclosures or cavities may also be used, provided they are closed.

Speaker Quantity

In main living areas, at least two speakers should be used to achieve good sound quality. For small rooms or ancillary spaces, a single speaker is usually sufficient.
Depending on the room size, we recommend planning the following number of speakers per room:

Ceiling installation

Plan the speaker installation positions to be evenly distributed throughout the room. A minimum distance of 50cm/20″ from walls should be maintained to avoid sound reflections.

In ceiling installations, the stereo effect is barely noticeable and can often be neglected. Therefore, a full stereo signal is later assigned to each individual speaker via the connection to the Audio Player block (Downmix).

Wall installation

At the most frequently used listening position, at least two speakers should be arranged to achieve a good stereo effect.
The left-right assignment of the speakers is made later through the connection to the Audio Player block.

Programming examples

Example 1:

A Master and Client Speaker line on the same Audio Player function block

A room with limited space

3 Client Speakers are connected and paired with one Master Speaker

1 Audio Player function block:

The speakers always behave identically in terms of selected source and volume.

Example 2:

A Master and Client Speaker line on different Audio Player function blocks

Small restaurant with a bar, the two areas are acoustically adjacent

5 Client Speakers are connected and paired with one Master Speaker

2 Audio Player function blocks, 1x for restaurant, 1x for bar, both combined in a fixed group:

Both areas can sensibly only play the same audio source. However, the volume at the bar can be changed or muted independently of the restaurant.

If different audio sources are to be played simultaneously in two or more rooms, an additional Master Speaker must be used per room.

Example 3:

2 lines consisting of 1 Master and 1 Client Speaker each

Two separate living spaces

One Client Speaker is connected to each respective Master Speaker per room and paired

1 Audio Player function block per room:

Both rooms can be operated completely independently in terms of source and volume.

LED Status

Status LED Description

Device was selected in Loxone Config and is identifying.

Connection to Audioserver or Miniserver Compact is okay, but the device has not yet been paired or is offline.

Device operational, paired and online.

Device cannot connect to the Audioserver or Miniserver Compact via Tree Turbo.

SD card cannot be read. Check SD card.

Diagnostic Inputs

Summary Description Unit Value Range
Amplifier limit If the temperature of the amplifier reaches a critical point, the volume of the zone is reduced. This may be due to overloading or excessively high ambient temperature. - 0/1
Online Status Install Speaker 10 Master 1 Indicates whether the device can be reached by the Miniserver.
Diagnostics for Air devices
Diagnostics for Tree devices
Diagnostics for Extensions
Digital 0/1
Temperature Shutdown If the CPU temperature reaches a critical point, the outputs of the device are switched off. This can be due to short-circuits, overloaded switching loads or too high an ambient temperature. Digital 0/1


Summary Description Value Range Default Value
Serial Number Specifies the serial number of the device.
For Extensions: Enter 'Auto' to automatically pair an extension with unknown serial number.
This can only be used if there is only one Extension of the same type.
Save into the Miniserver, in order to pair the Extension.
Afterwards the program must be loaded from the Miniserver to transfer the actual serial number of the Extension into the program.
- -
Monitor Online Status When selected, you will be notified via System Status or the Mailer if the device is no longer available or goes offline. - -
Maximum Volume Determines the maximum (physical) output power of the amplifier in percent, thus limiting the maximum possible volume for this output. The volume values from 0-100% of the Audio Player or App are scaled accordingly. 0...100 100
Gain Increases or decreases the volume of this output in percent. Adjusts the volume of outputs used with different speakers or in different environments, making it possible to achieve equal volume levels. Is scaled and limited with the specified maximum volume. -20...20 0

Safety Instructions

Installation must be carried out by a qualified electrician in accordance with the applicable regulations.

Install the speaker in a way that the electronics on the back are protected from contact, damage, dirt and moisture.

This device must not be used as part of safety-critical systems.
