6.5.2 Pair 1 and Pair 2 Controls
These controls configure the audio pair and specify the output route.
•
Mute:
When selected, applies a mute to the audio output pair.
•
Mute on V bit:
When selected, applies a mute to the audio output pair when the valid-
ity bit (timeslot 28 in the audio 32-timeslot subframe) is not set to zero, i.e. when
defective samples are detected.
•
2 Channel:
When selected, configures the pair as separate L/R channels.
•
Stereo:
When selected, configures the L/R channels as a stereo pair.
•
Non PCM:
Enables routing of non-PCM data with the Source L / Non-PCM selection.
If in Non-PCM mode and a PCM source is selected, it will bypass the sample rate
converters and be routed to the output but the Procamp and Audio Delay controls will
have no effect.
If set to PCM mode and a Non-PCM source is selected, silence will be embedded.
•
Invert L / Invert R:
Inverts the signal (PCM sources only).
•
Gain L / Gain R:
The slider bar may be used to independently adjust the channel
audio gain over a range of +12 dB to -72 dB in 0.1 dB steps (PCM only). The preset
value is 0.
•
Left/NonPCM:
Routes the Left (PCM) or Non-PCM channel data to the option
selected in the window. Options for the channel include a dis-embed path, a tone or
silence.
•
Right:
Routes the Right (PCM) channel to the option selected in the window. Options
for the channel include a dis-embed path, a tone or silence.
