[SOLVED] DJM-750, Master Level control & SPDIF output vs. USB

Hi.  The Master Level control on the DJM-750 adjusts the signal level at the SPDIF output... but it has no effect on the USB REC (output).

Is this intentional, or is this a bug in the initial release of his mixer?  Should not the USB REC and the SPDIF outputs be identical?
