Listening Mode Options and Usage
Listening Mode Options
Stereo
This mode plays a stereo source in its pure, unprocessed form. It is the default factory setting
for any analog signal and any PCM or Dolby Digital 2/0 source coming through the digital
inputs.
It can be used to downmix a multichannel source format into a mixed stereo output signal.
Mono
This mode plays mono source material or stereo that has been mixed to a mono form. It can
be used to downmix a multichannel source format into a single mixed mono output signal.
The audio can be output to the center channel only or to the front left and front right
channels as a dual mono signal.
Two advanced configurations apply only to mono sources and outputs.
Analog Source (applies to Input 5 only) — If two mono signals are input on input 5
(analog), the user can choose whether the source input for the mono decoding mode is
Left Only, Right Only, or L+R (Sum). The default option is L+R (Sum).
Output Channels — This adjustment lets the user select whether mono signals are output
to the center channel (Center Only) or a dual mono signal is sent to the right and left
front channels (Front L+R Only). The default option is Front L+R Only.
Stereo to All
This mode plays stereo or downmixed stereo sources to all stereo channel output pairs in the
system.
If the source is a single analog mono signal and the listening mode is set to Stereo to All, the
following conditions apply:
z
If the mono source is set to left channel only, the audio is output only to available left
channels in the system.
z
If the mono source is set to right channel only, the audio is output only to available right
channels in the system.
z
If the mono source is set to L+R (Sum), the audio is distributed evenly as a dual mono
signal to all available stereo pairs.
Mono to All
This mode plays mono or downmixed mono sources to all channel outputs in the system.
The mono source (Left Only, Right Only, or L+R (Sum)) can be selected using the
SSP 7.1 Setup and Control Software or SIS commands.
Dolby Digital 5.1
This mode is used with Dolby Digital encoded source formats. It produces up to 5.1 discrete
channels (center, left and right front, left and right surround, and a low frequency effects
channel).
