Figure 99. Audio Format Correction
In this table, a left-only signal coming in on the Stereo input is sent to the
Left and Right outputs of the Stereo output group. The -6 dB value divides
up the signal equally into both sides of the stereo pair. Using this gain value
insures that the mono sum is the same as the original signal level.
Audio Group Substitution
The Audio Input table can be used to pre-configure an audio group substi-
tution. In
Figure 100 three stereo audio groups are defined. The source may
have normal stereo for the main program and the Cantonese output, but
the Mandarin channel is not available. In this case, it is desirable to substi-
tute the original stereo audio for the Mandarin rather than leave it silent.
