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.

7 KNX object description / Input gain
7.1 Explanation
Any number of audio sources can be connected to the 4 audio inputs of the Autrix. Such audio sources must
hand over their signal as an analogue LF signal (normally via cinch socket).
As various audio sources may supply output levels of different strengths, appropriate compensation can take
place on the Autrix. For this, the 4 inputs on the Autrix can be set independently of one another. This setting
is termed input amplification. In the as-delivered state, a medium input gain is assigned to all the inputs. This
presetting can be changed as necessary using the following communication objects. The settings described
in this chapter are intended for first start-up. Normally, the input sensitivity of an input need not be changed
in later system operation.
Please note that a high input amplification can lead to distortion of the music signal!

8 KNX object description / Setting (save/reset)
8.1 Explanation
In the as-delivered state, the Autrix is already assigned with a default sound setting. These settings are
suitable for most requirements.
If necessary, the sound settings can be adapted to construction-side conditions using the named KNX
communication objects.
Such adaptations can be saved permanently in the Autrix via an additional data point. This ensures that,
after voltage returns, the Autrix works with the adapted sound settings.
The data point "Reset" allows restoration of the factory sound settings.
In order to save these permanently to the Autrix, the above-mentioned data point can be used to save sound
settings.
During the saving operation (approx. 5 seconds), the Autrix does not react to bus telegrams.

9 Operating via frontpanel
The Autrix also can be controlled via the frontpanel keyboard, independently of the KNX building bus.
The following functions are available:
- switching the amplifier board On/Off
- volume setting
- routing (assigning an input source to an amplifier zone)
- adjust bass settings
- adjust trebel settings
- master mute ON/OFF
figure: frontpanel
9.1 Power / ON - OFF
Via this button the Autrix can be switched on or off. The green „power“ LED shows the current state.
In off state the Power-LED is also off. The Autrix is than in a stand-by-mode and can be turned on again at
any time. During the stand-by-mode the Autrix can also be turned on again by the KNX-interface.

9.2 Setting an input source for a zone
To allocate a certain input signal to a zone, the following operating steps must be accomplished:
1) selecting the input signal:
for this purpose the „IN“ key has to be pushed/confirmed until the LED line „IN“ shows the required
input-number.
2) selecting the target zone:
for this purpose the „OUT“ key has to be pushed/confirmed until the LED line „OUT“ shows the
required zone number.
3) confirming the selection (input signal/target zone):
for this purpose the „ROUTING“ key has to be pressed. This key works after the toggle principle:
pressing the key several times changes the status between:
- tieding the preselectet output / input
- untieding the preselectet output / input
9.3 Setting the volumne for a zone
To set the volume for a zone, the following operating steps must be accomplished:
1) Selecting the target zone:
for this purpose the „OUT“ key needs to be pressed until the LED line „Out“ shows the required zone
number.
2) Setting the volume:
for this purpose the keys „VOLUME+“ and „VOLUME-„ need to be pressed. Accordingly to which key
is being used, the volume changes in the before selected zone. The currently set value will be shown
in the LED line „IN“.
9.4 Setting the tone control for a zone (bass control)
To adjust the bass for a zone, the following operation steps must be accomplished:
1) Selecting the target zone:
for this purpose the „OUT“ key needs to be pressed until the LED line „Out“ shows the required zone
number.
2) Adjusting the bass:
for this purpose the keys „BASS+“ and „BASS-„ need to be pressed. Accordingly to which key is
being used, the volume changes in the before selected zone. The currently set value will be shown
in the LED line „IN“.
9.5 Setting the tone control for a zone (treble control)
To adjust the trebels for a zone, the following operation steps must be accomplished:
1) Selecting the target zone:
for this purpose the „OUT“ key needs to be pressed until the LED line „Out“ shows the required zone
number.
2) Adjusting the trebels:
for this purpose the keys „TREBLE+“ and „TREBLE-„ need to be pressed. Accordingly to which key
is being used, the treble changes in the before selected zone. The currently set value will be shown
in the LED line „IN“.

9.6 MasterMute / ON - OFF
The use of the function MasterMuste sets the Autrix to complete silence.
Over the „MUTE“ key, it can be turned on or off.
This key works after the Toggle principle:
pressing the key several times changes at a time the status between:
mute (muting) and unmute (cancel muting)
pressing the key several times changes the status between:
- mute (muting)
- unmute (cancel muting)
The actual state is shown at the LED „MUTE“ (icon „crossed out speaker“)
10 Installing and connecting the device
The device is mounted in a 19" rack. A free SCHUKO® socket is required for mounting.
• Connect the bus cable.
• Connect the LF inputs and loudspeaker outputs.
• Connect the power supply cable.
The Programming button and LED and the interfaces are only accessible from the rear side of
the device. If possible, load the physical address and application software into the device before
final mounting.
Because of the fact, that the device doesn´t come with a main switch, it should be secured separately through
a proper and appropriate marked domestic installation fuse located in the electric dirstributor.
