If you have digital audio devices connected to the
896mk3, 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 your host
software to SMPTE time code, follow the
directions in “Syncing to video and/or SMPTE
time code using a synchronizer” on page 23.
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
your host’s audio output menus. When operating at
high sample rates, the phones must mirror one of
the other output pairs.
Optical input and output
To make a 896mk3 optical input or output available
in your host software, choose the appropriate
format (
ADAT optical or TOSLINK) from the
optical input and/or output menu. If you won’t be
using the optical connectors, turn them off.
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 your OS X host audio software audio input
menus, you’ll see an 896mk3 input called
Return
1-2 . This is a stereo feed from the 896mk3 that
matches the signal 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.
☛
Warning: the Return inputs can cause
feedback loops! DO NOT assign this input to a
track that shares the same 896mk3 output pair as
the returns.
Reverb return
The 896mk3 also supplies a return to your host
software that carries the output of its reverb
processor. This return can be used for any purpose
you wish.
