We have released version 6 firmware for the AD-16. Specific issues addressed in this firmware are:

When the AD-16 is locked to an external Word Clock input, DIP switch 6 now offers the
following functionality:

o DIP6 DOWN – the unit runs at a sampling rate equal to the Word Clock input rate;
o DIP 6 UP – the unit runs at a sampling rate twice the Word Clock input rate.
o DIP 6 should be set UP to run the AD-16 at a 96kHz Word Clock when locking to a 48 kHz word clock.

Settings of DIP switches 3 & 4 now correspond correctly to what is noted in the manual

Word Clock Out is in phase with Word Clock In
CRC byte computed correctly
