SPDIF cannot be used to handle status bit because the specification does
not allow it.
B) To enable the 6300 to change its operating mode in response to AES status
bits received at its AES input:

Navigate to S
ETUP
> N
ETWORK
&R
EMOTE
> AES S
TAT
B
ITS
.

Set I
N
>M
ODE
to O
N
.
Unless you are sure that upstream equipment will correctly format these
bits, set
I
N
>M
ODE
to O
FF
.

Make sure that the equipment driving the 6300 is formatting its output as
AES3. SPDIF will not work.
C) To send “two-channel mode” and “stereophonic mode” bits indicating the
6300's current operating mode, set
M
ODE
>O
UT
to O
N
.
If this parameter is set to
O
FF
, then the 6300 will output “0000” (“mode
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
SER
B
ITS
control
set to B
LOCK
(default setting), which configures the User Bit channels of both
Digital Out 1 and Digital Out 2 to contain all zeros.
Setting the 6300's U
SER
B
ITS
control to P
ASS
DO1 will cause the User Bit channel
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
NPUT

6300
IN>MODE
setting =
O
FF
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,
navigate to
S
ETUP
> N
ETWORK
&R
EMOTE
> AES S
TAT
B
ITS
> AES U
SER
B
ITS
and set
the field to
P
ASS
or
B
LOCK
as desired.
Unless you are sure that downstream equipment will correctly format
these bits, set
AES U
SER
B
ITS
to B
LOCK
.
User bits can only be passed if the 6300’s digital output is set to AES , not
SPDIF .
