almando Multiplay Surround Decoder Installation And Operating Instructions Manual page 14

In the section below there are controls
for the currently active input.
The horizontally arranged buttons
offer the option to switch Dolby Pro
Logic off or on with the desired mode
and thus store it permanently for this
currently active input. After changing
the input or restarting the device, the
last Dolby Pro Logic mode will be used
again.
In the area of the volume control, the
volume value of the currently active
input is shown on the far left. And if the
volume control with the app in the
input settings has been activated for
this input, a volume control and a mute
button are available to the right.
For some inputs - HDMI and SPDIF2
(TV) - it will display a slider below that
allows you to adjust the volume
balance between the ambient and the
spoken sound. For better speech
intelligibility, move the slider to the
right towards the speech bubble. And
if, on the other hand, you want to make
the annoying commentator quieter
during a football game for example,
then move the slider to the left in the
direction of the ambient sound
(represented by a note symbol). This
assumes that the current TV program
is being broadcast in multichannel
audio.
At the bottom, you will find the toolbar
to navigate to the other pages of the
app, which are described individually
on the next pages.
