Manual Default Stereo
The
Manual Default Stereo Program B
matrix used by this profile is set for stereo
program signals. The program matrix settings are displayed in the following
Tool
Box

Figure 62: Manual Default Stereo Matrix Settings
You will notice that the
Phone
and
Aux
inputs are set for mono audio sources
and are being sent to both
Encoder 1
and
2
(the left and right channel encoders).
Each of the analog outputs,
CH 1 Out
and
Ch 2 Out
, are receiving incoming
audio via
Decoders 1 & 2
respectively.
Inputs 1
and
2
are set for a stereo
program audio source.
Input 1
is being sent to
Encoder 1
and
Input 2
is being
sent to
Encoder 2
.
PPM 1
is monitoring left channel program sound and
PPM 2
is monitoring the
right channel.
Important Stereo Connection Note:
If you are using the
Manual Default Stereo
profile (or a custom stereo profile you
have created), and you are connecting using two POTS lines, if for some reason
you lose one connection, the bandwidth of the single remaining connection will
be split to provide two channels of audio (audio quality will be reduced if this
occurs). If the bandwidth of this POTS connection drops below 21,600 bps,
audio will default to provide mono audio on the left channel only. This will
continue until the bit rate increases to 21,600 bps. At this bit rate two channels
will be returned. This will occur automatically.
