c If PMT Order is selected, you must set the PMT order for each audio (None,
AUD1 to AUD64). You cannot select the same PID for both audio devices. If
you select the same instance of an audio PID for one of the audio devices, the
other audio device PID instance will automatically increment by one. For
example, Audio 1 is set to AUD1 and Audio 2 is set to AUD2. If you change
Audio 1 source to AUD2, the Audio 2 source will automatically change to
AUD3 to resolve the conflict.
3 There are two audio settings. The Audio Setup area allows you to configure the
two balanced audio outputs on the rear panel (Audio 1 and Audio 2), known in
the Web GUI as 1 and 2, respectively.
a From the Audio Mode drop-down list, choose the output mixing.
Select Stereo (Left and Right are passed directly through to Left and Right),
R-Mono (Right is passed to both the Left and Right), L-MONO (Left is passed
to both the Left and Right), or Mixed (Left is passed to both the Left and
Right, and Right is passed to both the Left and Right).
b From the AC3 Compression drop-down list, choose the mode to use if the
output is compressed Dolby Digital audio. The selections are Line Mode,
Custom 1, Custom 0 or RF Mode. RF Mode is recommended for analog cable
modulators.
c From the Left Attenuation drop-down list, choose the volume adjustment for
the Left audio channel. You can select a value in the range from -6.0 dB to
+6.0 dB, in increments of 0.5 dB.
d From the Right Attenuation drop-down list, choose the volume adjustment
for the Right audio channel. You can select a value in the range from -6.0 dB
to +6.0 dB, in increments of 0.5 dB.
4 Click Apply.
