Chapter 18: Record Setup 347
You can display a track’s input levels in its Vol-
ume/Peak/Delay indicator. Normally, this indi-
cator is set to be a Volume indicator. When you
change it into a Peak indicator, it can function
as a headroom indicator based on the last peak
playback level.
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 au-
dio interface so they match those of your mix-
ing console and other audio devices in your stu-
dio.
The 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.
The 888|24 I/O has adjustable trim pots for its
inputs and outputs. For more information, see
the 888|24 I/O Guide.
There are no input or output trims on the fol-
lowing audio interfaces: 192 Digital I/O, 96 I/O,
96i I/O, 882|20 I/O, 1622 I/O, and 24-bit ADAT
Bridge I/O. Some Digidesign I/Os that do not
have output trims (such as the 96i I/O) offer
software-controllable input levels, adjustable
from Setup > Hardware (refer to the guide for
your particular I/O).
Connecting a Sound Source
Depending on your Pro Tools hardware I/O, you
can connect different types of sound sources
(such as musical instruments, mics, and mixer
outputs). Refer to the Setup Guide for your
Pro Tools system. For additional information,
refer to the documentation that came with your
sound source.
If you connect a sound source to a Pro Tools in-
put that was not previously configured to accept
input, you will need to reconfigure you hard-
ware in the Hardware Setup dialog (see your
Setup Guide). You may also need to reset your I/O
signal paths in I/O Setup (see Chapter 6, “I/O
Setup.”).
Allocating Hard Drive Space
for Recording
The Operation preference for Open Ended Record
Allocation
determines how much of your avail-
able hard drive space is allocated whenever you
record into one or more tracks in Pro Tools.
When this allocation preference is set to Use All
Available Space
, the drive’s entire available space
is allocated. This setting lets you record lengthy
takes, or longer sessions.
However, when allocating all available space,
Pro Tools may take a little longer to begin re-
cording. You can reduce this delay by allocating
a specific amount of time for recording.
You can also avoid recording delays by put-
ting Pro Tools in Record Pause mode before
beginning to record. See“Prime for Record
Mode” on page 372.
