CH C1 - C1 D;A Controller (with SYNC_IO Board) + D1 SACD;CD Drive (with SYNC_IO Board)

Simple D1 - C1 connection
More generally, when a C1 has no SYNC_IO board, it can only clock itself to the incoming audio stream (clock source is AUDIO IN)
when playing a CH-LINK, AES EBU, COAXIAL or OPTICAL input. The same applies for multichannel setup when CH products have no
SYNC_IO board. In such case:
• D1clock source: INTERNAL
• C1 clock source (for this input): AUDIO IN
If in this configuration (clock source = AUDIO IN) the C1 is not able to lock (open padlock) on an incoming S/PDIF audio stream
but properly detects its sampling frequency (a valid Fs is displayed instead of “Fs UNKNOWN” in the upper left corner of its
display), it probably means that the S/PDIF source does not comply with AES standard and/or has too much jitter. To overcome this
problem, set the clock source as “SRC” for this input. It will add an asynchronous sample rate conversion stage that has a wider
locking range.
4.5.3 C1 D/A controller (with SYNC_IO board) + D1 SACD/CD drive (with SYNC_IO board)
When both the C1 and the D1 are equipped with a SYNC_IO board, optimum performance are obtained when the C1 DAC is the
clock master, and the D1 drive is the clock slave. Audio stream goes from the D1 to the C1, but clock goes the other way. Schematic
below shows to connect such system:
