Number of Loxone speakers per room

The number of Loxone speakers to achieve perfect sound depends on your room size. See the table below for an idea of how many to use.

1-15m² 1 Loxone speaker
16-20m² 2 Loxone speakers
21-40m² 2 Loxone speakers
>40m² 4 Loxone speakers

Selection of a suitable backbox

Positioning of the Loxone Speaker

There are 2 types of Loxone Speaker. One is designed to be installed into the ceiling with a backbox behind it and the other is a surface mounted, standalone speakers for wall mounting/placing atop things. Both speakers should be installed in a room to provide the best stereo sound possible under the most used listening area, I.E the sofa in a living room, table in a dining room etc. Because of this, it is a good idea to utilise the ceiling speakers in pairs. To avoid sound reflection, you must ensure that there is at least 50cm between the speaker’s edge and any nearby walls.

Wiring of the Loxone Speakers

When wiring for a Loxone Speaker, there are a few key factors to take into consideration. Distance and nearby interference sources are 2 crucial ones. Please keep in mind that Loxne Speakers have 2 tweeters for stereo sound and thus 4 cores would need to berun to these in order to accommodate for this. For distances up to 20m, a cable with a cross-sectional area of 1.5mm² should suffice with a 2.5mm² one being sufficient for distances up to 50m. For distances over 50m the cable thickness must be adjusted according to volt drop and other factors. It is also strongly recommended that you keep speaker cable – mains cable contact to a bare minimum and place the speaker cables in their own unqiue conduit to assist with preventing interference.

Amplifier

The Loxone 12 channel amplifier allows for operation of up to 12 Loxone speakers or 12 Loxone Wall Speakers. These can be grouped in any fashion allows 2 or more speakers to be run into any room depending on the size of the zone.

MONO / STEREO MODE

The Loxone speakers can be operated in mono or stereo mode. In the stereo mode, the stereo signal is then reproduced in the loudspeaker via the two tweeters. In larger rooms, two speakers are recommended in mono mode and in smaller rooms a speaker in stereo mode is recommended. For the wiring, this means:

  • Loxone Speaker in mono mode
    • A loudspeaker cable and an amplifier channel for each speaker
  • Loxone Speaker in stereo mode
    • Two speaker cables and two amplifier channels per speaker

The following diagram shows 4 different possibilities of audio cabling:

ZONE 1

In this zone you get a mono-sound via a Loxone Speaker. The speaker is switched to mono and connected to an amplifier channel with a loudspeaker cable. The RCA cable is connected to the jack on the Musicserver and with the white or red RCA plug on channel 5. On the amplifier the setting from the switch to LineIN is left for the channel. It is also possible to use a Y-Cinch cable, which combines the signals from the red and white RCA plugs and passes them to the amplifier, so you do not lose a soundtrack.

ZONE 2

In this zone you get a stereo sound over two Loxone speakers. The speakers are switched to mono and connected to a respective amplifier channel with a loudspeaker cable. The jack cable is connected with the jack on the Musicserver and with the white RCA plug on channel 3 and the red on channel 4. On the amplifier the setting from the switch to LineIN is left for the two channels.

ZONE 3

In this zone you get a stereo sound over four Loxone speakers. The loudspeaker is switched to mono and connected to a respective amplifier channel with a loudspeaker cable. The jack RCA cable is connected with the jack on the Musicserver and with the RCA plugs to “BUS In 1” from the amplifier. On the amplifier channel 7 to 10, the setting is switched from the switch to “BUS1”.

ZONE 4

In this zone you get a stereo sound via a Loxone Speaker. The loudspeaker is switched to stereo and connected to two amplifier channels with two loudspeaker cables. The jack cable is connected with the jack on the Musicserver and with the white RCA plug on channel 1 and the red on channel 2. On the amplifier, the setting from the switch to LineIN is left for the two channels.

LINE-IN INPUT DELAYS

When using Line-In inputs, please bear in mind that there will be a delay for these. Unfortunately, there isn’t anything that can be done about these delays as it is caused by the music server processing the signal it is receiving from the Line-In and then distributing it to where it needs to go. Please also note that this isn’t unique to Loxone’s Music Server, but it is a property of every Music Server.
