Correcting Format Differences
The Input tables can be used to rectify format differences in sources. For
example, a VTR or Disk server that may have many different programs
with different audio channels but is always connected to the Maestro as a
stereo pair of channels. It is standard in many facilities to use the left
channel only for mono programs.
The Audio Input table can be used to correct this format difference as
shown in
Figure 84 :
Figure 84. 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
the signal equally into both sides of the stereo pair. Using this gain value
will insure that the mono sum is the same as the original signal level.
