sample rate since the sample rate is determined by the external clock
source.
• WC (44/48) directs Mobile I/O to clock off of an external Word Clock
Source at single rate (e.g. fs = 32k-50k)
• WC (88/96) directs Mobile I/O to clock off of an external Word Clock
Source at double rate (e.g. fs = 64k-100k)
• WCx256 (44/48) directs Mobile I/O to clock off of an external 256fs
Clock Source at single rate (e.g. fs = 32k-50k)
• WCx256 (88/96) directs Mobile I/O to clock off of an external 256fs
Clock Source at double rate (e.g. fs = 64k-100k)
• ADAT (44/48) directs Mobile I/O to clock off of the incoming ADAT
stream and run at single rate. All 8 ADAT channels are available. You will
generally want to select this source if you intend to use ADAT input.
• ADAT (88/96) directs Mobile I/O to clock off of the incoming ADAT
stream and run at double rate. The bottom 4 ADAT channels are multi-
plexed over the lightpipe to provide 4 channels of double rate audio com-
patible with other SMUX and Alesis 96k ADAT devices. If you are using a
device that provides 4 channels of 96k audio over ADAT optical, you will
want to select this clock source.
• DigIn (44/48 ) directs Mobile I/O to clock off of the selected stereo dig-
ital input at single rate (e.g. fs = 32k-50k). This allows operation of the dig-
ital input without SRC, and from devices that must supply clock.
• DigIn (88/96) directs Mobile I/O to clock off of the selected stereo dig-
ital input at double rate (e.g. fs = 64k-100k). This allows operation of the
digital input without SRC, and from devices that must supply clock.
2. The Sample Rate popup menu allows you to select the sample rate
when you are using internal clock. The Mobile I/O must be running
on internal clock for the Sample Rate popup menu to have any
effect. If the Mobile I/O is running from an external clock source,
you cannot select the sample rate since it is determined by the
external clock source.
