2 Connect the AES/EBU or S/PDIF input on the
enclosure to the AES/EBU or S/PDIF output of
your DAT deck. Route the digital input to
Pro Tools inputs in the Hardware Setup dialog.
Connecting Effects Units
The 192 I/O, 192 Digital I/O and 96 I/O let you
connect analog or digital effects units to your
Pro Tools system, and use them as inserts or
make them the destination for effects sends and
returns. (The 96i I/O supports a single pair of
hardware inserts using channels 1–2. See the
96i I/O Guide for more information.)
Five inserts are available on each audio channel.
Each insert can be a hardware insert (or software
plug-in), and can be mono or stereo.
When using a hardware insert, you must con-
nect the device to matching inputs and outputs
on your system. For example, a stereo insert
could use outputs 7–8 and inputs 7–8 for the
sends and returns, respectively. Routing the
physical inputs and outputs of the interface to
Pro Tools inputs and outputs can be done in ei-
ther the Hardware Setup dialog or I/O Setup di-
alog. From I/O Setup, inserts can also be defined,
and their channels mapped to audio interface
channels. (For more information, see the
Pro Tools Reference Guide).
You can also connect effects units to your sys-
tem by using any analog or digital inputs and
outputs as Auxiliary Inputs and Outputs for ef-
fects sends and returns. Once an effects unit is
attached this way, you can send a variable
amount of a track’s output to the effects unit us-
ing a send in Pro Tools.
Ten separate send controls on each Pro Tools
track allow you to route audio to any of the
available outputs connected to your system or
through any of the 128 internal busses in the
Pro Tools Mixer. Outputs can be returned to
Auxiliary Inputs for automated mixing or pro-
cessing.
When you are using an effect in this send and
return type of configuration, make sure the
unit’s internal mix or balance between direct
(unprocessed) and wet (effected) signal is set so
that only the processed signal is returned to
Pro Tools. On most effect units, a balance set-
ting of 100% (completely wet) is the appropriate
setting.
If you’ve been using an effects unit in an instru-
ment setup, such as a guitar effects rack, you’ll
probably find the balance to be below 50%. If
the unit has separate dry and effect level knobs,
turn dry level control off. If you don’t do this,
the dry, unprocessed signal will be present in an
effect’s output along with the desired processed
sound, and you’ll have trouble accurately con-
trolling the effect balance in your final mix.
You can route any of the physical input or
output pairs to any of the input and output
channel assignments in the Pro Tools
mixer. (The 96i I/O does not support input
mapping, however.) For more information
see the Pro Tools Reference Guide.
