MENU SYSTEM
Saving Audio Processing Favorites
The 4x1 Switcher w/ Audio Decoding, allows any of five audio processing modes
to be associated with a selected input.
For example, you may want to associate the Multichannel Stereo audio
processing mode with the optical (TOSLINK) input. On the other hand, you may
want to set the Dolby Pro Logic II (PLII) audio processing mode when using the
analog L/R inputs, in order to create discrete multichannel audio when using a
surround system. These two examples will be illustrated.
Available Modes
Mode Description
DIRECT
Audio playback without any processing (default setting).
The input signal is the same as the output signal.
STEREO
Multichannel audio is down-mixed to two-channel audio
and routed to the Front Left / Front Right speakers.
MCH STER
Mixes the SL and FL channels to the Front Left Speaker;
Mixes the SR and FR channels to the Front Right Speaker.
If the Center channel is present, then the Front Left, Front
Right, and Center channel will be used to produce a stereo
image. If the Center channel is not present, then only the
Front Left and Front Right speakers will produce the stereo
image.
MONO
If the Center channel speaker is present (or enabled), the
audio is played only through the Center channel (the Front
Left and Front Right speakers will be muted). If the Center
channel speaker is not present (or disabled), Front Left
and Front Right signals will be combined and played out of
the Front Left and Front Right speaker.
PLII
Transforms two-channel stereo into high-quality
5.1-channel surround sound.
NOTE:
PLII (Dolby Pro Logic II) Mode processes the stereo signal
source into five separate full frequency channels.
