OPTIMOD 6300 DIGITAL
C) To send "two-channel mode" and "stereophonic mode" bits indicating the
6300's current operating mode, set M
If this parameter is set to O
not indicated'). This is probably the safest available mode if you are un-
certain whether downstream equipment can respond appropriately to
these bits.
22. Set up response to AES3 user bits (optional).
The 6300 can pass AES user bits from its input to digital output #1. The default
behavior is to block these bits because they may cause downstream equipment
to respond in unexpected ways. Because the vast majority of audio applications
make no use of User Bits, we recommend keeping the 6300's U
set to B
(default setting), which configures the User Bit channels of both
LOCK
Digital Out 1 and Digital Out 2 to contain all zeros.
Setting the 6300's U
of Digital Out 1 to be filled with the bits received from the User Bit channel of
the signal feeding the 6300's Digital In. We recommend such setting only if your
facility requires it and all three of the following conditions are met:
 The sample rate of your digital source (feeding 6300's Digital In) is no higher
than 48kHz
 6300 DO1 SYNC setting = I
 6300 IN>MODE setting = O
Unless all of the above conditions are met, the user bit passthrough may lose
data.
To enable the 6300 to pass user bits from its digital input to its digital output,

the field to P
ASS
Unless you are sure that downstream equipment will correctly format
these bits, set AES U
User bits can only be passed if the 6300's digital output is set to AES, not
SPDIF.
23. Set the Processing Delay for a given signal path (optional).
[minimum], [30 fps], [29.97 fps], [25 fps], [24 fps], [33-50 ms in 1 ms increments]
You can set the delay through the AGC+LIMIT and MB+LIMIT signal paths inde-
pendently. This feature is usually used in sound-for-picture applications to add
time delay so that the input/output delay through a given processing path is ex-
actly one frame, using a variety of different standards. The selections are
M
INIMUM (depends on processing structure in use; typically between 20 and 23
ms), 30 fps, 29.97 fps (NTSC color video), 25 fps (most PAL video), and 24 fps
(film). You can also set the delay in 1 millisecond increments.
