Fostex PD-6 operation manual

• Before activating the jam function, check that the following conditions are satisfied. 1. The [TIME CODE IN] connector is receiving external time code.

2. The time display on the Normal screen is set to “LTC IN” and external time code value is shown.

3. The external time code frame rate matches the [FRAME] select switch setting. Otherwise, if you try to activate the jam function, “Illegal Frame!” is shown on the display and the operation is ignored.

• The following shows the basic jam operation procedure.

1. Feed external time code from a VTR, etc. to the [TIME CODED IN] connector.

2. Set the [JAM] switch to “ON”.

The display shows “—ForceJAM!—” and the internal generator takes over generating time code.

3. Cut off the external time code from the [TIME CODE IN] connector.

• Set the “Jam mode” menu in the TC Setup mode if required (see “TC Setup mode” on page 86 for details).

When receiving external time code, the internal generator can jam to it.

The user bit of the external time code is copied and maintained. Runs the internal generator by the free run mode, and records the current internal generator time as the start time.

Jam function

The jam function of the PD-6 internal generator allows to take over generating time code after the generator locks to the external time code timing.

Using the PD-6 jam function, the PD-6 time code generator can run with extreme accuracy (its own crystal accuracy) after it locks to the external time code. Therefore, you can make PD-6 recording in sync with the VTR even if you disconnect the time code input after the PD-6 generator locks to the external time code. In other words, you can use the PD-6 away from the VTR, which is essential for location recording.

The jam function is available only when the [TC GEN] select switch is set to “FREE RUN”.

The table below shows how the PD-6 reacts depending on the [TC GEN] switch setting when you set the [JAM] switch to “ON”.
