Sample rate
Choose the desired overall sample rate for the
896mk3 system and AudioDesk. Newly recorded
audio in AudioDesk will have this sample rate.
Imported audio or soundbites in existing files that
do not match this sample rate will be displayed in
the Soundbites window with a red ‘X’ on their
move handles to indicate that they cannot be
played.
Clock Source
This setting is very important because it
determines which audio clock the 896mk3 will
follow.
If you do not have any digital audio connections to
your 896mk3 (you are using the analog inputs and
outputs only), and you will not be slaving
AudioDesk to external SMPTE time code, choose
Internal .
If you have digital audio devices connected to the
MOTU 828, or if you are not sure about the clock
source of your setup, be sure to read “Making sync
connections” on page 21 and “Clock Source” on
page 37.
If you are slaving the 896mk3 and AudioDesk to
SMPTE time code via the 896mk3 itself, choose
SMPTE and follow the directions in “Syncing to
SMPTE time code directly” on page 22.
Buffer Size
The Buffer Size setting can be used to reduce the
delay — or monitoring latency — that you hear
when live audio is patched through your 896mk3
hardware and AudioDesk. For example, you might
have MIDI instruments, samplers, microphones,
and so on connected to the analog inputs of the
896mk3. If so, you will often be mixing their live
input with audio material recorded in AudioDesk.
See chapter 10, “Reducing Monitoring Latency”
(page 69) for complete details.
Phones
This 896mk3 setting lets you choose what you’ll
hear from the headphone jack. For example, if you
choose
Main Out 1-2 , the headphones will
duplicate the main outs. Or you can choose any
other output pair. If you choose
Phones 1-2 , this
setting makes the headphone jack serve as its own
independent output pair. As a result, you’ll see
Phones 1-2 as an additional audio destination in
AudioDesk’s audio output menus. Note that when
operating at high sample rates, the phones must
mirror one of the other output pairs.
Optical input and output
To make an 896mk3’s optical inputs and/or outputs
available in AudioDesk, choose
ADAT Optical or
TOSLINK from the optical input and/or output
menus. If you won’t be using the optical
connectors, turn them off. Note: these settings can
only be accessed in the MOTU Audio Setup
application. For details, see “Optical input/output”
on page 39.
Main Outs Assign
Use the Main Outs Assign setting to determine
what audio you will hear on the XLR main outs of
the 896mk3. If you would like to treat them as their
own separate output pair, choose
Main Outs .
Return Assign
In AudioDesk’s audio input menus and the Bundles
window, you’ll see an 896mk3 input called
Return
1-2 ( Figure 8-2 ) . This is a stereo feed from the
896mk3 that matches the output of one of its
output pairs. Use the Return Assign menu in
MOTU Audio Setup to choose which output pair
you would like to hear on this return. This can be
used, for example, to record back a final stereo mix
that includes effects processing from the 896mk3
DSP (such as the Leveler) for reference and
archiving purposes.
