Set up Timecode Output - :pulse

Set up Timecode Output

Your :pulse is designed to send timecode data to other devices, such as your sound mixer/recorder or other Timecode Systems products. By using the same timecode, the devices can all have synchronised time and user bits (metadata).

There are two different ways of outputting timecode data to sound mixers:

  • via the TC port with a TCB-20 (5-pin to 5-pin LEMO) cable.
  • via the TC/SYNC port with a TCB-10 (BNC to BNC) cable. This method requires the Sync Output mode to be set to LTC, and as the port is being used for timecode, it cannot be used for sending a word clock signal.

 

Timecode output via TC

  1. Use a TCB-20 (5-pin to 5-pin LEMO cable) to connect your sound mixer to the TC port on your :pulse.
  2. Set your sound mixer to receive external timecode. Refer to the manufacturer's instructions for more information.
  3. Switch on your :pulse unit (see Switch :pulse On and Off).

    If your :pulse is a slave in a BLINK network, it will receive timecode settings from the master in the network and send them to the sound mixer.

    If your :pulse is a master in a BLINK network, it will send timecode settings to the sound mixer/recorder. The timecode settings are either set manually for the :pulse in the TC Generator menu, or come from an external source, depending on which master mode the :pulse is using.

  4. This step only applies if your :pulse is in Int-Gen TX or Ext-TC/C TX mode. To set the :pulse's internal timecode settings, apply the following settings in the TC Generator menu:
    • Set T/C - set the timecode that will be sent to the sound mixer/recorder.
    • Set U/B - set the user bits (metadata) that will be included in the timecode data that is 'stamped' on the sound mixer/recorder's recording.

 

Timecode output via TC/SYNC

If you don't have a TCB-20 5-pin to 5-pin LEMO cable, you can set your :pulse to output timecode via the TC/SYNC port. But where possible, we recommend that you use the TC LEMO port for timecode output instead.

  1. Use a TCB-13 BNC to LEMO 5 cable to connect your sound mixer/recorder to the TC/SYNC output port on your :pulse.
  2. Set your sound mixer/recorder to receive external timecode via its TC 5 pin LEMO input. Refer to the manufacturer's instructions for more information.
  3. Switch on your :pulse unit (see Switch :pulse On and Off).

  4. Access the Sync Generator menu and set the Set BNC O/P Mode to LTC. This sets your :pulse to output timecode via the TC/SYNC port. The sound mixer/recorder should now receive timecode from the :pulse.

If the sound mixer/recorder does not receive timecode from the :pulse, it may need a High output signal. To set this, access the Sync Generator menu, select the Set BNC O/P Level option, and change it from Normal to High. (If the BNC output was already set to High, change it to Normal).

Remember to repeat this synchronisation process every day - if the :pulse is not resynchronised, the sound mixer's audio recording will start to go out of sync. This is because the sound mixer will use its internal clock to set the start time of its audio recordings. As the sound mixer's internal clock is unlikely to be as accurate as the :pulse's clock, it may suffer from drift, resulting in the timecode and recording being out of sync.
