‘GENERAL’ TAB SETTINGS
Sample Rate
Choose the desired Sample Rate for recording and
playback. The UltraLite-mk3 can operate at 44.1
(the standard rate for compact disc audio), 48,
88.2, 96, 176.4 or 192KHz. If you have a S/PDIF
device connected to the UltraLite-mk3, make sure
that it matches the UltraLite-mk3’s sample rate.
☛ Mismatched sample rates cause distortion and
crackling. If you hear this sort of thing, check the
sample rate settings in your hardware and here in
MOTU Audio Console.
S/PDIF at 4x sample rates (176.4 or 192kHz)
At the 4x sample rates (176.4 or 192kHz), all analog
I/O remains active, but S/PDIF digital I/O is
disabled.
Clock Source
The Clock Source determines the digital audio
clock that the UltraLite-mk3 will use as its time
base. The following sections briefly discuss each
clock source setting.
Internal
Use the Internal setting when you want the
UltraLite-mk3 to operate under its own digital
audio clock. For example, you may be in a situation
where all you are doing is playing tracks off hard
disk in your digital audio software on the
computer. In a situation like this, you most often
don’t need to reference an external clock of any
kind.
Another example is transferring a mix to DAT. You
can operate the UltraLite-mk3 system on its
internal clock, and then slave the DAT deck to the
UltraLite-mk3 via the S/PDIF connection (usually
DAT decks slave to their S/PDIF input when you
choose the S/PDIF input as their record source).
If you would like help determining if this is the
proper clock setting for your situation, see
“Connecting and syncing S/PDIF devices” on
page 22.
Figure 5-1: MOTU Audio Console gives you access to all of the settings in the UltraLite-mk3 hardware.
