D-108 Owner’s Manual (Digital Recording)
Setting up a digital input track
1. Select the desired track using the “Setting digital
input tracks” menu in SETUP mode.
You can select any track from tracks 1–8 to assign to L or
R. You can also select [adat] instead of tracks 1–8 to
digitally record all eight-track data from an external adat.
When you finish setting the parameters in SETUP mode,
be sure to press the EXIT/NO key or the STOP key to exit
SETUP mode.
Selecting a recording track
1. Press the RECORD TRACK select key of the
recording track to set that track in ready mode.
Starting and quitting recording
1. Locate the top of the Program.
2. Make sure that [DIGITAL] and [EXT SYNC] indicator
lights up on the display. Hold down the RECORD
button and press the PLAY button to start recording
on the D-108.
3. Start playback on the external digital device.
Check to see if the level meter of the D-108 is moving,
responding to the input signal.
4. When recording is complete, stop the D-108 and
the external digital device.
Caution: Do not connect or disconnect an optical cable to
or from the DATA IN jack of the D-108 while a track is assigned
as digital input. Otherwise, noise may be induced to the D-
108, affecting the connected digital device.
Note: While a track is assigned for digital input, you cannot
use the same track for analog recording via the corresponding
input jack. When you finish digital recording, set the “Setting
digital input tracks” menu to [L: -, R: -] (no assign).
However, in other tracks not assigned for digital input, it is
possible to record analog signals. For example, if tracks 1
and 2 (L: 1, R: 2) are selected for digital inputs, then digital
signals in tracks 1 and 2, and analog signals in other tracks
can be recorded, thus making it possible to simultaneously
record digital and analog signals on all eight tracks . Refer to
page 51.
When the "Setup of the digital input track" is set to "adat,"
please note that tracks 1 ~ 8 will all be assigned to digital
input and thus, analog signals cannot be recorded in any
of the tracks.
Note: When setting up the digital input track, the tracks to
be assigned to L and R cannot be the same, such as [L: 4]
and [R: 4]. If setup is executed by mistakenly selecting the
same track numbers for L and R, the number setup for the L
channel will be given priority and “
- ” (no assign) will be
setup automatically.
Setting the sampling rate for a recording
program
<Important>
When a digital signal is to be input to D-108, be sure to set
the D-108 sampling rate identical with the external digital
equipment. In the case of adat digital signals or S/P DIF
digital signals, recording is also possible although the setup
sampling rates may not be identical but if digital recording is
executed with the operating clock set to [Opt.] by the
aforementioned [Clock Sel.?] menu, it will be recorded at a
speed different from the true figure. The reason for this is
that when the digital input track is setup in D-108, the word
clock external sync (D-108 will be operated by the external
equipment clock) will be applied to the S/P DIF or adat digital
signals that is input. Also, as the operating clock will not be
by external sync if digital recording is executed with the [Clock
Sel.?] set to [Int.], difference in speed will not occur. However,
as it will operate similar to an FS converter, sound quality
might deteriorate. However, although [Clock Sel.?] is set to
[Int.], when loading from an external DAT or adat, or if the
SETUP mode [Slave mode?] is ON and the [Slave Type?] is
adat or S/P DIF, it will momentarily enter external sync of the
digital input. If digital input and output are both connected,
be careful to avoid creating a digital loop.
* In the case of a S/P DIF digital signal, if the sampling rate
setting is different, 44.1kHz or 48kHz inside the display will
blink to warn that the sampling rate is not correct.
* For details on the sampling rate setup procedure, refer to
"Setup of the sampling rate" menu of the SETUP mode.
* In the following, the explanations will be in the assumption
that this is a digital mixer possible in input of digital signals
whose clock source can be setup at digital IN.
After setting the sampling rate, press the DISP SEL key to
display the REMAIN indication and check the remaining time
available for recording. If there is not enough time for
recording, try to increase the time by using the Erase function
to move the REC END point of another Program forward, or
by saving the song data of Programs that are not often used
to a DAT machine to clear that data from the unit.
• See page 121 for more information on Setting the sampling rate.
Note: A 48kHz sampling rate setting requires more disk
space then 44.1kHz setting. This means that the available
recording time would be shorter.
• See page 70 for more information on the Erase function.
• See page 88 for more information on Saving song data.
When a track is assigned and a correct digital signal is
input, the FD-8 displays [DIGITAL] on the display.
If incoming digital signal is abnormal, the [DIGITAL] and
[EXT SYNC] indicators flashes. Refer to “Setting digital
input tracks” in the “Changing the Initial Settings (SETUP
Mode)” chapter on page 117.
