D24—Owner's Manual
Since the output of the Time Compression and Pitch Change function
is recorded to the specified virtual track, you must assign the virtual
track to a main track in order to play the result. See "Using Virtual
Tracks" on page 51 for more information.
The D24 does not support MMC when it's configured as an MTC or
SMPTE/EBU timecode slave. See "MMC Hookup Examples" on page
180 for more information.
Make sure the D24 is set to the correct MMC device number. See
"Setting the MMC Device Number" on page 179 for more informa-
tion.
External disk drives must be turned on before the D24, otherwise they
won't be recognized. See "Using External Disk Drives" on page 154
for more information.
When a high-resolution digital audio signal is transferred to a
lower-resolution system, care must be taken to ensure that the digital
audio samples are truncated correctly. See "Digital I/O &
Wordlength" on page 189 for more information.
The WORD CLOCK OUTPUT transmits the internal wordclock signal
only when the WORD CLOCK 75 TERM/THRU switch is set to TERM.
See "Wordclock Connections" on page 123 for more information.
The WORD CLOCK OUTPUT transmits the wordclock signal received
at the WORD CLOCK INPUT only when the WORD CLOCK 75
TERM/THRU switch is set to THRU. See "Wordclock Connections" on
page 123 for more information.
When the timecode source is set to SERIAL IN, only command infor-
mation is received via the SERIAL I/O port. A timecode connection
from the timecode source to the D24's TIMECODE INPUT is also
required. See "Selecting a Timecode Source" on page 135 for more
information.
When the timecode source is set to REMOTE IN, the wordclock source
is also set to REMOTE IN and the source selected using the Wordclock
function is ignored. When the timecode source is set to a different
source, the wordclock source reverts to its previous setting. See
"Selecting a Wordclock Source" on page 124 for more information.
Try adjusting the brightness. See "Setting the Display Brightness" on
page 171 for more information.
See "Ejecting Troublesome Disks (emergency use)" on page 174 for
more information.
