Hello, I purchased this USB to I2S converter to run to the Opus through a Metronome. I am currently trying to get it working without the Metronome. The module has MCK, LRCK, SCK, data, and ground pins. Is it a faulty assumption that SCK is the same as BCK on the Opus? The Metronome has separate BCK and SCK pins and from reading the schematic it looks like SCK should be used as MCK. Is this accurate? Thanks, vlad Edited by user Wednesday, March 21, 2012 5:10:14 PM(UTC)

On the metronome SCK = system clock which is likely the same type signal as the master clock or your USB module. You typically won't supply a master clock to the metronome. On your USB module your SCK may mean serial clock which is the same as the bit clock or BCK on the metronome. I hope that helps you. Edited by user Wednesday, March 21, 2012 5:22:17 PM(UTC)

That's what I originally thought but just silence when connected to the opus and a single note when the metronome is included in the chain. Just to verify, on all dip switches the bit of plastic above the switch does reflect the logic, i.e. + is 1, 0 is open, - is zero, correct? Edited by user Wednesday, March 21, 2012 7:31:07 PM(UTC)

Yes + = high logic 1
O = open
- = Low logic 0
