delay Compensation
There is a delay of four samples between MADI input and output.
For conversion of all 64 channels (@ 1 FS) of a MADI signal two
ANDIAMOs may be daisy-chained. To ensure phase locked opera-
tion of all audio channels the delay between two ANDIAMOs will be
compensated then.
Delay compensation becomes active, if an ANDIAMO ‘sees’ another
ANDIAMO at its input. The ‘second’ ANDIAMO will switch to ID 02.
Indication of ID 2: LED <bank selection> heartbeat (see
„Bank Se-
lection / Signal Routing“ on page 26
).

To ensure proper detection for delay compensation no other device
must be connected in between two ANDIAMOs.
