S/PDIF
Next to the
ADAT
connectors is a pair of connectors labeled
S/PDIF
,
IN
and
OUT
. These S/PDIF connectors are used to transmit digital data among
digital audio devices via an electrical signal. S/PDIF data can use the full
24-bit sample width used internally on Layla24.
When connecting devices to the S/PDIF jacks on Layla24, the use of
standard analog RCA audio cables is not recommended. For reliable S/PDIF
operation, 75-ohm coaxial (RG59) video cables are recommended.
Word Clock
Next to the S/PDIF ports are the
Word Clock
connectors. These connectors
allow you to synchronize one Layla24 to another Layla24, Layla, Mona or
to other digital audio devices.
The word clock I/O uses a BNC connector. As with the S/PDIF I/O, a
shielded 75-ohm (RG-59) coaxial video cable should be used. BNC
connectors are widely used in the electronics industry for both video and
computer networking. However computer networks use 50-ohm (RG-58)
coaxial cables and not the 75-ohm (RG-59) cable used by video. For reliable
word clock operation, use only video grade cables with Layla24.
