1 General description:
The Autrix is an Audiomatrix with integrated amplifier stages. With the Autrix music can be distributed into
varies areas. Scope of application is from private homes to office buildings.
Basically due to the modulare structure, there is the possibility of various expansion options.
The basic version is available with the following technical features:
Input: 4 stereo audio input (NF signals)
Output: up to 8 speaker output (8 Ohm)
2 stereo audio output (NF signals)
The AUTRIX is directly connected to the KNX building bus. So the controlling can be made by the installed
switch range/visualisation.
The device can also be controlled directly over the front panell located on front of the device.

Speaker Audio OUT Audio IN RS232 KNX Option Net
3.1 Loudspeaker connections
Only speakers with the following features can be connected to the AUTRIX:
Capacity: min. 30 W
Impedance: 8 Ohm
The speaker cabling is connected to the Autrix via srew terminals. These srew terminals allow the connection
of cabels up to 2,5 qmm.
3.2 Audio Output (NF)
In addition to the amplifier outputs the Autrix also sends unreinforced audio signals. These signals can be
connected to external amplifier.There are two of those audio outputs available:
Audio signal of zone 1 (stereo)
Audio signal of zone 2 (stereo)
These NF-signals are logically connected to the same KNX communication objects, as the amplifier output.
3.3 Audio Input (NF)
Up to 4 onsite audio devices, are connected to the 4 audio NF inputs (stereo RCA sockets) of the Autrix.
These audio input signals are then available for all integrated amplifier stages (up to 8 amplifier).
3.4 RS232 Port
Not available in current version.

3.5 KNX Port
The connection to the KNX bussystem occurs by screw terminal type Hartmann/PTR BU9502, which is
included in the scope of delivery.
The power consumption of the KNX connection is listed in the data sheet.
3.6 Option
The ports are not occupied and irrelevant for the operation at the KNX system.
3.7 Power Supply
The power supply is send to the Autrix via a power cord (IEC60320-C13), which is included in the scope of
delivery.
4 KNX Object description / general functions
4.1 General describtion
The Autrix comes with several data interfaces. Which means that the device can be activated over several
protocols. Normaly the device is destined for the connection to the KNX builduíng bus. This section
describes the controlling of the Autrix over the KNX communication objects..

Via the communication object 1 the amplifier board can be switched ON or OFF. Object 2 sends back the
status. Even after switching off the amplifier boards the Autrix can still receive or send telegrams.
Switching off the amplifier board is recommended, if the autrix will not be in use for a longer period of time
(for example: nighttime, vaccation etc.).

status
1.001 ON/OFF
Via the communication object 4 the master mute can be switched ON or OFF. Object 5 sends back the
status. If master mute (value 1) is set, all amplifiers are on silent.
The value 0 sets the amplifier back to the state before the muting.
Switching off the amplifiers via the master mute is recommended, when all amplifier outputs need to be set
to silent momentary (for example incomming phonecall, announcement etc.).
4.5 Alarm - overheating

Alarm overheating
status

In case of overheating of the system this object will be sent with value 1.
At the end of the alarm (temperature back to normal) the status will send the value 0.
During the period of the alarm the Autrix M4 is switched off automatically. Afterwards the Autrix M4 needs to
be turned on again (through KNX Bus or trough the front panel oft he device).

The input signals for the amplifiers (audio zones) are selected via these communication objects. There are 4
input signals available. By sending the value 1 to a communication object, it will be switched to the next
higher input number. Equivalent the value 0 switches to the next lower input number.

The input signals for the amplifiers (audio zones) are selected via these communication objects.
There are 4 input signals available. Sending…….
….value 1 connects the amplifier n with the audio input 1.
….value 2 connects the amplifier n with the audio input 2.
….value 3 connects the amplifier n with the audio input 3.
….value 4 connects the amplifier n with the audio input 4.
Value 0 would clear the routing.

Via these communication objects the amplifier mute can be switched ON or OFF. If the amplifier mute (value
1) is set, the equivalent amplifier is set on silent. Value 0 sets the amplifier back to the state before the
muting.
The master mute (see previous chapter) is always higher ranking than the amplifier (zone) mute. If master
mute is set, all zones (amplifiers) are muted. But the master mute does not overwrite the communication
object of the muting of the individual amplifiers. So if the master mute is set to vealue 0, again this data point
is relevant to mute or unmute the individual zone.
