Chapter 5: Recording/Playback

Recording digital audio

When recording digital audio, you do not need to make mixer settings described earlier. Instead, you have to make the following settings.

Note that time code is recorded according to the time code generator mode setting (see the next page).

<"INPUT" status indication while recording digital audio>

When a correct digital audio signal is fed to the [DIGITAL IN] connector, the PLL (Phase-locked loop) is activated and begins locking to the input signal.

When the unit locks to the digital input signal, the "INPUT" area on the display looks like the one on the left below. This indicates that the digital input takes priority and you can record the digital signal directly to the stereo tracks (L and R).

Note that the unit cannot adjust the input level when recording a digital audio signal. Adjust the external digital source level.

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 PD204. 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 142).

Selecting the system clock

To record a digital signal, set the system clock of the PD204 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 175).
