Sample rate
Choose the desired overall sample rate for the 8pre
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 its move
handle to indicate that it cannot be played.
Clock Source
This setting is very important because it
determines which audio clock the 8pre will follow.
If you do not have any digital audio connections to
your 8pre (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
8pre, or if you are not sure about the clock source of
your setup, be sure to read “Syncing optical
devices” on page 20 and “Clock Source” on
page 26.
If you are slaving the 8pre and AudioDesk to
SMPTE time code via the 8pre itself, choose
SMPTE and follow the directions in “Setting up for
SMPTE time code sync” on page 62.
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 8pre
hardware and AudioDesk. For example, you might
have MIDI instruments, samplers, microphones,
and so on connected to the analog inputs of the
8pre. If so, you will often be mixing their live input
with audio material recorded in AudioDesk. See
chapter 10, “Reducing Monitoring Latency”
(page 45) for complete details.
Optical input and output
To make a 8pre optical input or output available in
AudioDesk, choose ADAT from the optical input
and/or output menu. If you won’t be using the
optical connectors, turn them off. Note: this
settings can only be accessed in the MOTU Audio
Setup application.
Phones
This 8pre setting lets you choose what you’ll hear
from the headphone jack. For example, if you
choose Main Outs 1-2, the headphones will
duplicate the main outs. Or you can choose any
other output pair. If you choose Phones, 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: this
settings can only be accessed in the MOTU Audio
Setup application.
BE SURE YOU HAVE ENOUGH VOICES
Go to the Setup menu and choose Configure Audio
System> Configure Studio Size. Then check to make
sure you have enough mono and stereo audio
voices to cover the 16 channels of input and 12
channels of output provided by your 8pre —
although the number of channels may depend on
how your 8pre is configured:
■ 8 channels for analog input and output
■ Zero or 8 channels for optical, depending on
whether you have optical turned on or off
For example, if you are using analog only, you only
need 8 voices. If you are using analog and optical,
you need 16 voices.
TRIMMING THE MIC/INSTRUMENT INPUTS
The 8pre mic/instrument inputs provide trim
knobs on the front panel. To calibrate an audio
input:
1 Record-enable a track in AudioDesk.
