Console Software31Console SoftwareS/PDIF – The Sony/Phillips Digital Interchange Format is a serial bit-stream thathas a clock signal embedded in the data stream. When recording from an S/PDIFsource, whether via optical cables or RCA cables, Layla3G & Gina3G will utilizethe synchronization clock that is embedded in the S/PDIF while they decode thebit-stream. Layla3G & Gina3G can only sync to S/PDIF clock if the master deviceis set to a sample rate between 30kHz and 100kHz. Otherwise you will get noiseand/or loss of sync.Note: When recording from a S/PDIF port, you must select S/PDIF as theinput clock. For greater flexibility, this is not done automatically. If youfind that your S/PDIF recordings contain pops or skips, be sure that youhave selected S/PDIF as your input clock.ADAT – The Alesis ADAT optical interface can send and receive up to 8simultaneous channels of digital audio data over fiber optic cables. Unlike wirecables, fiber optic cables do not add noise or interference. Layla3G & Gina3G cansend out (or “master”) ADAT clock as well as slave to it. If you want Layla3G orGina3G to slave to an ADAT clock, just set the input clock to the ADAT setting.Layla3G/Gina3G can only sync to ADAT clock if the master device is set to asample rate between 40kHz and 50kHz. Otherwise you will get noise and/or lossof sync.Note: To preserve the high audio quality of Layla3G/Gina3G’s converters itis best to use the Internal input clock setting instead of synchronizing to anexternal ADAT clock, which may add unwanted jitter to the signal.Now let’s take a look at some sample configurations and how you might set themup from a synchronization standpoint.Let’s start with a simple example. Suppose that Layla3G is the only audio deviceused in your system. Since you have no other devices to synchronize with, simplyselect Internal for Layla3G’s input clock. Layla3G will then use its own clock tocontrol its operation.Now a little more complicated set-up: You have two Layla3Gs connected. Simplyset Layla3G #1 to Internal for its input clock. Now connect the first Layla3G to
