Fostex PD204 Digital audio input connection, Time code input connection, Sync signal connection

Chapter 4: Basic connections

Digital audio input connection

The PD204 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 XLR-3-31 type connector.

When the PD204 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 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).

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 177).

When the PD204 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 PD204 provides the [WORD/VIDEO IN] connector (BNC type) which is used to lock the PD204 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 PD204 locked to the external de- vice.

External audio signal connection for monitoring

The signal fed to the [AUX IN (L, R)] connectors are routed to the monitor circuit. Using this facility, you can monitor the audio signal from an external device such as a camera.

The balanced XLR-3-31 type connectors are used for the [AUX IN (L, R)] connectors.

<Note>: You cannot record the signals fed to the [AUX IN (L, R)] connectors.
