Chapter 5: Recording/Playback

Recording digital audio

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 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).

<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.

Selecting the sampling frequency/bit length

You can select the Fs (sampling frequency) and bit length for recording.

<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).

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).
