Recording digital audio
Selecting recording source
Using the "Rec source sel" item in the "SYS SETUP" menu of the MENU mode, you can select
the recording sources for each track pair (1-2, 3-4, 5-6, L-R) (see page 146 for details about
the "Rec source sel" menu item). By default, "Digital" is selected for track pairs 1-2, 3-4 and
5-6, while "ST BUS" is selected for track pair L-R. In this condition, you can record digital
inputs 1 through 6 to tracks 1 through 6, while you can record the stereo-mixed signals to
the stereo L/R tracks. Note that the maximum number of recordable tracks depends on the
Fs/Bit setting (see page 85).
Before executing recording of digital audio, you have to make the following settings besides
track arming. Note that time code is recorded according to the time code generator mode
setting (see the next page).
Selecting the system clock
To record a digital signal, set the system clock of the PD606 to "DIGITAL" for synchronizing
with an external device (by default, the system clock is set to "INT (Internal)").
When the unit receives a correct digital audio signal and locks to it, "DIGI" is shown on the
Home screen. If the unit does not lock to the incoming digital signal, "DIGI" flashes.
If you want to synchronize the unit to a video or word clock, set the system clock to "VIDEO"
or "WORD" appropriately.
You can select the system clock via the quick setup mode or the "Sync clock" item in the "SYS
SETUP" menu of the MENU mode (see pages 75 and 181).
Selecting the sampling frequency/bit length
You can select the Fs (sampling frequency) and bit length for recording.
<Note>:
When the "Rec source sel" item is in the default condition and correct digital
signals are fed to channels 1 through 6, the "INPUT" area on the display looks like the
one on the left below ("Digital" is shown and "1" through "6" are highlighted). When
correct digital signals are not fed, analog signals take priority and the "INPUT" looks like
the one on the right below ("Analog" is shown and "1" through "6" are not highlighted).
<Note>: If you set the record sources of all pair tracks (1-2, 3-4, 5-6 and
ST-LR) to "Digital" using the "Rec source sel" menu item, when correct
digital signals are fed to digital inputs 1 through 8, the "INPUT" area on
the display looks like the one on the right. In this condition, the stereo-
mixed signals are not recorded to the stereo L/R tracks because digital
input 7-8 signals are recorded to the L/R tracks.
<Note>: The sampling frequency of the digital input signal must match the Fs/Bit setting
of the PD606. You can set the Fs/Bit via the “Record FS&Bit” item in the “SYS SETUP”
menu of the MENU mode (see pages 76 and 144).
