The Autrix sends the bass setting status value back to the appropriate zone using these communication

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!

The input gain of the appropriate audio input can be controlled via these communication objects. The data
point is intended for steppwise modification of the input amplification. When the value 1 is sent to a
communication object, the system switches to the next highest value. Accordingly, the value 0 switches to
the next lowest value.
