In Wednesday’s post we took a look at how one can easily expand your interfaces inputs with an ADAT enabled set of mic pres. This is, of course, assuming your audio interface comes with an Optical ADAT connection. If you then go ahead and purchase one of these lightpipe devices, hook it up to your interface, and record enable your tracks you might notice some weird pops and clicks happening that are really annoying. This is the result of confusion on which device (your interface or lightpipe device) is acting as the clock source. Here’s the quick and dirty way to fix things in Pro Tools.

Once your lightpipe device is connected and powered up, go to the Setup menu and choose Hardware

This will open up a box that shows what your current clock source is selected as. Usually “Internal”. Which makes sense, you’re clocking with your audio interface’s internal clock. But if you want multiple digital devices to play nice you’ll need to let this new lightpipe device be the clock source. To do this simply click on the drop down box under Clock Source and choose Optical. Click OK and the problem should be fixed. Easy as pie!

If at some point you power off your lightpipe device, Pro Tools will prompt you that it is reverting back to the internal clock as it no longer sees an external one. You can always switch this back if need be. Enjoy!
