Why the SC311m and not the... 

RP311v2: Like the SC311m, the RP311v2 a 1 zone system. Amplifier, streamer, DAB+/FM tuner and line input are the same. However, the SC311m has the power supply built in, a line output, a digital TOSLink input, Bluetooth, WLAN, 2 more trigger inputs/outputs and the USB-C sockets.

Features of the SC311m

Streaming Client

Streaming is the number one source of music today. The trivum Streaming Clients can play all important music formats and enable a wide selection of music sources: Internet Radio (TuneIn), Spotify Connect, Deezer, Qobuz, Tidal, Sound-Machine, NAS, AirPlay, Text2Speech or WebURLs.

DAB+/FM Tuner

In addition to the streaming client, a DAB+/FM tuner is available. We don't want to do without the built-in tuner, especially for waking us up in the morning: Radio reception via DAB+/FM is always guaranteed, regardless of whether the internet is available. This gives you the certainty that music will actually come out of the speakers in the morning. 

Analog line input

This universal input can be used for e.g. CD players, turntables, computers and many other devices. The connected source can be heard in the zone served by the SC311m. The music signals are not passed on to other trivum SoundSystems via network. 

Audio extender solutions such as the trivumXT:LINE are ideal for bringing the sound from a distant source, e.g. from the television, into the technical room. a> and trivum XR:LINE an. When planning the cabling, a separate CAT 6/7 cable should be provided from the TV to the technical room so that the TV sound can be heard in other rooms or in the garden via the trivum Multiroom SoundSystem.

Digital TOSLink input

With this, e.g. the TV sound can be played back via the trivum SoundSystem.  

Bluetooth receiver

Thanks to the built-in Bluetooth receiver, the SC311m can be connected to any Bluetooth device. This makes it easy to play music - even from the smartphones of visitors who do not want to be given access to the WLAN in the house. Young people and children in particular use Bluetooth almost exclusively with their smartphones.

Analog line output

Sometimes 2x30 watts of output power are not enough: for example with wall speakers or when large floorstanding speakers are to be used. An external amplifier can then be used via the line output. Or you connect the normal loudspeakers to the amplifier output of the SC311m and the active subwoofer via the line output. In these cases, the built-in DSP helps with a high-pass filter for the normal speakers and a low-pass filter for the subwoofer.

Connection options for the USB-C sockets

The 2 USB-C sockets (MDAT and SDAT) are supported with software V10 (free update). Matrix devices, i.e. SC344m and SC311m, can be connected to each other via USB-C cable. 4 stereo sources (streamer, tuner, AUX) can be forwarded digitally from one device to a connected device with no time delay. In the revised setup, it can be determined very precisely which sources should be used where. The Matrix devices can, for example, access TV or microphone signals from other Matrix devices without any delay. The setup supports configuration with colored information about detected cables. There is also a new Connected Spaces feature that acoustically connects multiple zones without the need for grouping.


The SC311m has WLAN support. We recommend using the LAN connection. Connecting multiple SC311ms via WiFi is not recommended

Operation / Control

Thanks to the intuitive app, the system is very easy to use - both on smartphones and in the web browser or on the trivum TouchPads. Thanks to the trivum t3OS operating system, the trivum SoundSystems are simple and at the same time very flexible. It includes many additional functions that make the SC311m a powerful center in every house. 
Check out the operation right now in our Demo area on.

Sound and amplifier performance

The built-in digital stereo power amplifier with 2x30 watts sinus delivers more than enough power for built-in loudspeakers. The wattage specified for the speakers must be well above 30 watts. Because the watt value for the speakers indicates the maximum load on the speaker. If a loudspeaker is specified as 120 watts, this means that it can be operated with a maximum of 120 watts. Normal room volume is below 1 watt. Thus, 30 watts of amplifier power is more than enough power for multi-room built-in speakers.

Built-in speakers are often not perfectly tuned. This is due to the type of installation or placement. That's why every trivum amplifier has a built-in DSP (Digital Sound Processor). Thanks to the DSP, the frequency response can be meticulously adjusted. There are no fewer than 5 parametric equalizers, high and low pass, bass enhancement and of course bass, treble and balance per amplifier. This even makes it possible to equalize invisible flat panel speakers.

KNX Integration

Like all trivum Multiroom SoundSystems, the SC311m is also fully integrated in KNX. Simple KNX buttons can thus control the music in the room. 4 keys are enough! If a KNX visualization is available or planned, it can take over the music control. This is very easy, easy to use and brings real added value in the visualizations such as the GIRA QuadClient, Homeserver or GIRA G1/X1.

In addition to the possibility of controlling the music functions via KNX, each trivum Multiroom system also offers an independent KNX visualization. In addition to music, you can also control light (RGB, RGBW, tunable white), heating, roller shutters, etc. in the trivum app. Simple timers, presets and scenes are also part of the trivum visualization. Take a look at the KNX visualization in our Demo Area at.

Control4, URC or RTI integration

The SC311m can be integrated into the media control of RTI, URC and Control4 systems. The drivers, which are available free of charge, enable the integrator to integrate the completely individual media control. This allows the trivum Multiroom System to be controlled and further automated with the remote controls available from RTI, URC or Control4.

Paging / Text2Speech

The built-in paging function enables various announcements: either by microphone (connected to the line input) or by the Text2Speech function: Any text you enter is converted into speech and then played back as an announcement. Announcements are started by KNX or by actions and can be played in selected or all zones with predefined volumes. If necessary, also with a gong in front of it. The paging can also be used as a doorbell - or at the touch of a button "Kids please come up. Dinner is ready". 

Display of e.g. microphone announcements

Audio signals that are present at the analogue or digital input can be mixed in with the current music (e.g. a streaming service) with a microphone button in the music control. This can be activated per zone in the configuration. This is ideal for commercial use: microphone announcements are easily possible with background music playing.  


If there is more than one line input (the SC311m has 2: analogue + digital), the mix function can be used to listen to several players at the same time. The ratio of the line inputs to each other can then be set for each mix preset. A function that is used in conference rooms with multiple microphones. 

Background Music

Background Music makes it easy to listen to the same music - without grouping zones. This is ideal in commercial installations with many different areas. 
Background music is provided by a dedicated zone and all other zones can source music from that zone.


Each trivum Multiroom System has the option of defining macros and starting them via an action or a KNX event. A macro is a sequence of macro steps. A step can be a TCP, UDP, HTTP, MQTT, KNX, Delay or again a trivum action command. 

NodeRed / MQTT

To support IoT applications, every trivum multiroom system includes a simple NodeRed and MQTT interface. This allows you to connect the trivum Multiroom System to the whole world of IoT technology.

trivum API

Many functions of the trivum Multiroom System can be addressed via the trivum Developer API. This means that you have full access to the system with simple HTTP requests. You get full zone status information back instantly upon change in XML format. This allows you to integrate the trivum Multiroom System into your own visualization or media control.
