Pro Audio Support

Q:
I can't get 8 channels of TDIF at sample rates higher than 48k on the Tascam X48.
 
A:
Eight channels of double speed sample rate I/O on a single TDIF connection is a new development for TASCAM recorders and mixers. Please ensure that the equipment you are connecting the X-48 to will support this by contacting the manufacturer of that equipment.
