Technical Data; Troubleshooting - AEG AR 4023 DVD Instruction Manual

The term "Dynamic Range" describes the ratio of quietest
and loudest sound. If the dynamic range is very large, you
will experience very quiet and very loud sounds.
This may cause replay problems. Let us assume that you
are watching a DVD in a relatively loud environment. You
can now increase the volume to be able to hear also the
very quiet passages, however with the disadvantage that
loud passages will be unacceptably loud. In this case it
would make sense to compress the dynamic range (i.e.
reduce) and increase the output volume at the same time.
• FULL -2/8: The dynamic range is compressed slightly
(2/8) to full (FULL).
• OFF: The dynamic range is not compressed at all
(default).
Dual Mono
The Audio output is normally in stereo. Here you have
the possibility to choose Mono-output instead of Stereo-
output.
• Stereo: The Audio output is in Stereo (default).
• Mono L: The Audio output is in Mono. In this case the
signal of the "left" stereo channel is transmitted to all
speakers.
• Mono R: The Audio output is in Mono. In this case the
signal of the "right" stereo channel is transmitted to all
speakers.
• Mix Mono: The Audio output is in Mono. In this case
the signal of the "both" stereo channel is transmitted
to all speakers.
