Selecting a Wordclock Source 125
D24—Owner’s Manual
When the sampling rate is 88.2 kHz, the 44.1K and 96K indi-
cators both appear, as shown here.
If an acceptable wordclock signal is not found, the D24 will not operate and the LOCK
and FS indicators do not appear. In this situation, you must either select another word-
clock source, or correct the selected external wordclock source. This condition also
occurs when the external wordclock is disconnected or the device supplying it is turned
off.
5Press the [SETUP] button again to leave setup.
The SETUP indicator goes out.
When the timecode source is set to REMOTE IN, the wordclock source is also set to
REMOTE IN (the EXT indicator in the WC window lights up) and the D24 is automat-
ically configured as a wordclock slave. When the timecode source is set to a different
source, the wordclock source reverts to its previous setting. See “Selecting a Timecode
Source” on page 135 for more information.
Higher sampling rates offer improved sonic performance, but require more disk space.
A 640 MB Overwrite-type MO disk, for example, can store approximately 120 track
minutes of 16-bit, 44.1 kHz digital audio, compared with 55 track minutes of 16-bit,
96 kHz digital audio.
The sampling rate you choose will ultimately depend on your application and record-
ing system. In general, 44.1 kHz is used for music CDs and MiniDiscs, 48 kHz for some
professional recording applications, and 88.2 kHz and 96 kHz for professional record-
ing, mastering, and DVD (Digital Versatile Disk) applications. Since all devices in a dig-
ital audio system must be synchronized to a common wordclock, the sampling rate will
be the same for each device. So if the D24 is wordclock master and is running at 48 kHz,
when you mix down to DAT, for example, via a digital connection from the mixing con-
sole, the DAT recording will also be at 48 kHz.
If you intend to burn your own CDs, for example, it’s best to use 44.1 kHz, the standard
for music CDs. If you intend to deliver your project to a third party, a mastering studio,
for example, consult them and agree on a sampling rate before you start recording on
the D24. Although it’s possible to convert between sampling rates, using third-party
sample rate converters, choosing the correct sampling rate in the first place is the best
way to avoid this additional process.
When the Varispeed function is used, the sampling rate also changes. See “Using
Varispeed” on page 55 for more information.
