MOTU AUDIO SETUP

‘ULTRALITE’ TAB SETTINGS

Sample Rate

Choose the desired Sample Rate for recording and

playback. The UltraLite can operate at 44.1 (the

standard rate for compact disc audio), 48, 88.2 or

96 kHz. If you have a S/PDIF device connected to

the UltraLite, make sure that it matches the

UltraLite’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 Setup.

Clock Source

The Clock Source determines the digital audio

clock that the UltraLite 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 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 system on its internal

clock, and then slave the DAT deck to the UltraLite

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 21.

Figure 5-1: MOTU Audio Setup gives you access to all of the settings in the UltraLite hardware.
