Connecting Big Ben to a Pro Tools HD rig without using a Sync I/O

On this first page we will deal with connecting Big Ben to a Pro Tools HD rig without using a Sync I/O.

1) Connect a 75 ohm BNC cable between the WC Out connections of Big Ben and the EXT In of each audio interface. (as shown below)

2) Do NOT connect the LOOP Sync connections between the audio interfaces. To best take advantage of Big Ben’s superior clock, each interface must be connected directly to a Big Ben word clock output.

1) Determine the desired sample rate for the entire HD system, and set Big Ben to that Sample rate.

2) In Pro Tools software, Session>Setup> Click on the “Clock Source” field, select the first audio interface, and set its clock source to “Word Clock”

3) Repeat Step 2 for all audio interfaces. Note that selections made for previous interfaces will not be checked; this is normal.

4) Verify on the front panel of each audio interface that Sync Mode is set to EXT.
