In this guide we’ll show how to make a Sound Devices 788T 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 “43) Timecode: Frame Rate”
- Select your frame rate
How to make the 788T accept external Timecode:
- Enter Menu
- Go to “44) Timecode: Mode"
- Choose "Ext TC"
For the 788T you need a TC-IO cable.
Connect it to the 5-pin timecode connector.
Now the 788T 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 either video sync or wordclock. The 788T can read both sync signals.
- Enable external Genlock on 788T:
- Enter Menu
- Go to “5) Rec: Sync Reference”
- Choose either "Video Sync Input" or "Wordclock Input" depending on the setting in your Lockit.
For the genlock sync you need an extra cable - the SYNC-OUT
Connect it to the Sync Word/Vid In BNC socket.
Once the 788T has recognized the external sync source, the Input LEDs will stop flashing and the display will show a sync indicator on the right side. There will either be a "W" for Wordclock or a "V" for Video sync.
