Word Clock
Next to the S/PDIF ports are the
Word Clock
connectors. These connectors
allow you to synchronize one Layla to another Layla or to other digital
audio devices. In addition to a standard word clock signal, these connectors
also allow you to synchronize using the superclock format, which is 256x
the selected sample rate.
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 cables with Layla.
MIDI
The last set of connections to the Layla interface is for MIDI. The MIDI
ports can be used for receiving MIDI time code (MTC), sending MIDI
signals from your digital audio/MIDI sequencing software to external sound
modules, etc.
MIDI cabling is highly standardized and widely available.
