Audio connections – Layla24
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 audio data between
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, 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.
