Chapter 4: Basic connections

Digital audio input connection

The PD606 accepts digital signals conformed to IEC 60958 Part3 (AES/EBU) or IEC 60958 Part2 (S/P DIF) format (the format of the digital source is automatically detected).

The digital connection is made via the D-sub 25-pin DIGITAL I/O connector.

To record a digital audio source, follow the procedure below.

1)Connect a digital source to the [DIGITAL I/O] connector.

2)Use the "Rec source sel" item in the "SYS SETUP" menu of the MENU mode to set the record source appropriately (you can set the record source in channel/ track pairs: 1-2, 3-4, 5-6, L-R).

3)Set the system clock to "Digi in" via the quick setup mode or the "Sync clock" item in the "TC SETUP" menu of the MENU mode (see pages 75 and 181).

When the PD606 receives a digital source from the selected channel, the PLL (Phased- locked loop) circuit activates and locks to the input sync signal.

<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).

Time code input connection

The [TIME CODE IN] connector (balanced, XLR-3-31) accepts SMPTE/EBU time code. To record external time code, set the TC generator mode to "Ext Run" (Ext).

By default, the TC generator mode is set to "Rec Run", however, you can select the desired mode via the quick setup mode or the "Gen mode" item in the "TC SETUP" menu of the MENU mode (see pages 76 and 183).

When the PD606 receives "valid" external time code from the [TIME CODE IN] con- nector and the time display mode on the display is set to "LTC IN", you can view the incoming time code value as well as the frame rate (you can switch the time display mode using the [TIME/TC SET] key).

When incoming time code satisfies the following conditions, it is "valid".

1)Time code runs in normal direction and value is continuous.

2)Sync word matches the frame rate.

3)Time code is not dropped out.

•For details about how to jam to external time code, see "Chapter 5: Recording/ playback" described later.

Sync signal connection

The PD606 provides the [WORD/VIDEO IN] connector (BNC type) which is used to lock the PD606 to an external word or video reference.

The connector accepts a word or video clock from an external device (the clock type is automatically detected), which makes the PD606 locked to the external de- vice.
