B) Press
DIG OUT CALIB
soft key.
C) Adjust
DO 100%
to determine the maximum peak digital output level with refer-
ence to full-scale.
7. Set the DO RATE (Digital Output sample rate).
[32], [44.1], or [48kHz]
48kHz is preferred because its samples are synchronous with the peak con-
trolled samples in the processing.
Selecting a 32kHz output sample rate will automatically set 15kHz as the
highest available audio bandwidth.
DO RATE
will also affect the available range of test tone frequencies. When
DO RATE
is set to 32 kHz, the highest
TONE FREQ
setting is
15000 Hz. When
DO RATE
is set to 44.1 or 48 kHz,
TONE FREQ
range ex-
tends to 20000 Hz.
8. Set the DO SYNC (Digital Output Sync) mode to internal or external.
[internal] or [external]
The
internal
sync setting synchronizes the output words to the 6200 internal
clock. All inputs are subject to sample rate conversion.
The
external
setting synchronizes the output rate to the input rate. If a valid
AES/EBU signal is present at the
AES/EBU SYNC INPUT
on the rear panel,
it will be used for synchronization. If lock is unavailable at the SYNC
INPUT
, or if the
SYNC INPUT
exceeds ±4% of the selected output rate, the
AES/EBU INPUT
is used. If
both
the
SYNC INPUT
and
the
AES/EBU INPUT
exceed ±4% of the selected output rate, the unit automatically switches to in-
ternal
. The unit automatically returns to
external
sync after 1 second of con-
tinuously valid AES/EBU signal lock at a valid sample-rate. Furthermore,
external lock is only permitted when the output rate matches the sync (or
AES/EBU input) rate.
DO SYNC
may be
external
while
INPUT
is
analog
. In this case the analog
input provides the audio while the SYNC
or
AES/EBU
input provides the
sync for the digital output.
9. Set the SYNC DELAY through the processing.
[off], [24 ms], [30 fps], [29.97 fps], [25 fps], [24 fps], and [96 ms]
The 6200 can add time delay to make its input/output delay one frame, using
a variety of different standards. The selections are off
(approximately 14ms
delay), 24 milliseconds, 30 fps, 29.97 fps (NTSC color video), 25 fps (most
PAL video), 24 fps (film), and 96 milliseconds.
10. Set the desired output word length.
[16bits], [18bits] and [20bits]
The largest valid word length in the 6200 is 20 bits, limited by the sample
rate converters. (Internal word length is 24 bits.) The 6200 can also truncate
