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..

2

Amplifier board ON/OFF

status

1.001 ON/OFF

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.).

The object sends the temperature of the amplifier board as a status to the KNX bus. The correspondent
telegram will always be send, if the temperature has changed by minimum 1 degree.
