In this guide we’ll show how to make a Sound Devices 744T accept external Timecode and Genlock.
Turn on all your Lockit devices, choose one of them to be the Master Clock – then press-and-hold the green button to broadcast timecode and frame rate through ACN and you are set.
Make sure all devices and Lockits run on the same frame rate.
- On the Lockit, press green and red simultaneously to enter menu, then and navigate to “Project Rate”
- On the 788T:
- Enter Menu
- Go to “46) Timecode: Frame Rate”
- Select your frame rate
How to make the 744T accept external Timecode:
- Enter Menu
- Go to “47) Timecode: Mode"
- Choose "Ext TC"
For the 744T you need a TC-IO cable.
Connect it to the 5-pin timecode connector.
Now the 744T accepts the external timecode source. You can enter the Jam menu by pressing Menu and HDD simultaneously to confirm this.
How to set up Genlock:
- In the Lockit Menu set the Sync output to wordclock with the matching sample rate.
- On the 744T, no further adjustments are required. The recorder will automatically lock to a wordclock signal present on the input.
For Genlock sync you need an extra cable - the SYNC-OUT
Connect it to the Sync WORD CLOCK IN BNC socket.
Once the 744T has recognized the external sync source, it will display a "L" indicator on the right side of the home screen.
