To display a track’s peak level:
 Control-click (Windows) or Command-click
(Mac) a track’s Volume indicator to step
through the different indicator modes (Volume,
Peak, and Channel Delay) until the indicator
displays peak (pk) level.
Calibration Mode
(Pro Tools HD Only)
You can use the Calibration mode in Pro Tools to
adjust the input and output levels for your audio in-
terface so they match those of your mixing console
and other audio devices in your studio.
HD I/O has one set of adjustable trim pots for its
inputs. Additionally, the reference level for the in-
put can be set to +4 dBu or –10 dBV. For more in-
formation on calibrating HD I/O, see the HD I/O
Guide.
192 I/O has two sets of adjustable trim pots for its
inputs, and two sets of adjustable trim pots for its
outputs. Additionally, the reference level for the
input can be set to +4 dBu or –10 dBV. For more
information on calibrating 192 I/O, see the 192
I/O Guide.
There are no input or output trims on the following
audio interfaces: HD OMNI, HD MADI,
192 Digital I/O, 96 I/O, and 96i I/O. Some
Pro Tools audio interfaces that do not have output
trims (such as the 96i I/O) offer software-control-
lable input levels, adjustable from
Setup > Hard-
ware
(see the guide for your particular audio inter-
face).
Connecting a Sound Source
Depending on your Pro Tools audio interfaces,
you can connect different types of sound sources
(such as musical instruments, mics, and mixer out-
puts). See the User Guide for your Pro Tools sys-
tem. For additional information, see the documen-
tation that came with your sound source.
If you connect a sound source to a Pro Tools input
that was not previously configured to accept input,
you may need to reconfigure you hardware in the
Hardware Setup dialog (see your User Guide).
You may also need to reset your I/O signal paths in
I/O Setup (see Chapter 7, “I/O Setup.”).
Recording with a Click
If you intend to work with MIDI or Instrument
tracks in your session, or if the audio you’re work-
ing with is bar and beat-oriented, you can record
your tracks while listening to a click. This ensures
that recorded material, both MIDI and audio,
aligns with the session’s bar and beat boundaries.
When your track material lines up with the beats,
you can take advantage of some very useful editing
functions in Pro Tools, such as quantizing MIDI
and audio events or clips, quantizing individual
MIDI notes, and copying and pasting measures
and song sections in Grid mode.
Material that is recorded without listening to
a click can still be aligned to bar and beat
boundaries in Pro Tools with Beat Detective
(see Chapter 30, “Beat Detective”), or by us-
ing the Identify Beat command to determine
the tempo (see “Identify Beat Command” on
page 790).
