Selecting the audio source
WARNING
Danger of hearing damage!
Before switching to a different audio source, first set the volume on
the headphone amplifier to a low level. Different audio sources and
different listening material (e.g. different pieces of music on different
CDs/sound carriers) can have widely varying signal levels. In the
case where you switch to a higher level audio source from a lower
one without first reducing the volume level this can lead to high vol-
ume levels in the headphones and could damage your hearing.
▷
Set the volume on the headphone amplifier to a low level (see
page 22) before switching to a different audio source.
▷
Use the Input selection rotary switch to select your connected
audio source.
The Input selection LED lights up white, indicating the selected
audio source.
