Clicks or crackles occur on the outputs -
• Check that all cables are of a suitable type, connected correctly and not
damaged. In any multi-wire mode, a broken wire may not prevent the unit
locking but will corrupt the data.
• This can be caused by slaving some, but not all, of the system components
to a Master Clock. Note that if the unit is being driven by an upsampler, it

The Display turns on briefly when a button is pressed, then turns off

• If you are using Word Clock, connect this to Word Clock In. Set the BNC
item to RefCl. Press the SDIF-2 button – the unit should lock and display “b”
(for BNC) followed by the sample rate.
• Check that the Master Clock is switched on, set to the right sample rate and
does not require re-calibration.
• Connect a different piece of digital equipment to test the locking capability of
the unit. If the condition persists, contact your Distributor or dCS.

• If the sample rate is 48kS/s or lower, the De-Emphasis setting may be
incorrect. Press the De-Emphasis button repeatedly until the mode display
shows A (Auto).
• If this fails to correct the problem, the De-Emphasis flags in the data stream
may be incorrectly set (this is rare but it does happen. Press the
De-Emphasis button to cycle through 5, C and - in turn until the correct
setting is found. When you change to a different source, disk or tape, we
recommend setting De-Emphasis to Auto again.
