ATTENTION!
Listening over headphones at high audio levels can cause
hearing impairments! Also, switching between different audio
sources, connecting and disconnecting the transmitter, and
the transmitter going into standby mode can cause loud clicks
and pops which can impair your hearing! Therefore, always set
the volume control to minimum.

Step 6 Adjusting the analog audio interface level
This step is only required if the analog audio interface is used.
In order to achieve maximum audio volume at the headphones and maximum
dynamics of the digital transmission and to avoid clipping of the audio, it is
necessary to set the analog audio interface level of the transmitter to correspond
with the maximum audio level of the audio source.
This is done by turning the analog audio interface level control knob which will
change the audio level inside the transmitter before it is converted to digital audio
by the transmitter analog-to-digital converter.
While listening over the headphones, turn the input audio level control knob to the
position that yields maximum loudness of the audio at the headphones without
any clipping (distortion). If the level is set too low, the dynamics of the
transmission are not fully used. If the level is set too high, clipping (distortion) of
the audio will occur.
