METERS
These five-segment LEDs indicate signal level for
either the input or output channels 1–8. These
meters are calibrated at –42 dB, –18 dB, –12 dB,
–6 dB, and 0 dB, respectively. The 0 dB LED seg-
ment lights red if clipping occurs at the Input or
Output depending on whether IN or OUT is se-
lected.
IN/OUT Button Toggles whether the Meters
show the signal levels for either the Input or the
Output channels.
IN LED Indicates that the Meters are showing the
the signal levels for the Input channels assigned
in the Pro Tools Hardware Setup.
OUT LED Indicates that the Meters are showing
the signal levels for the Output channels as-
signed in the Pro Tools Hardware Setup.
MONITOR Controls
HD OMNI provides onboard monitoring from
mono up to 7.1 surround. Use the front panel
MONITOR controls to select the monitoring
path and adjust monitoring levels. You can con-
figure the following monitoring options:
• Control Room Outputs (MAIN and ALT as
configured in Pro Tools)
• MUTE, ALT, and CUE to Headphones
• Headphone Output
• SETUP
SETUP Enables (or exits) Setup mode. The
SETUP button LED is lit when in Setup mode
(for more information about Setup mode, see
Chapter 5, “SETUP Mode”).
CUE Enables (or disables) a dedicated stereo Cue
mix from Pro Tools that is sent to the head-
phones. The CUE button LED lights when en-
abled. When CUE is disabled, the headphones
monitor the same mix as the Control Room out-
puts (see also “CUE 1–2” on page 42).
Input/Output Meters
The front panel METERS only display the
eight analog/digital Input or Output chan-
nels assigned in the Pro Tools Hardware
Setup. Unassigned channels are not dis-
played on the front panel METERS. The
output METERS only show signal level from
Pro Tools output channels. They do not dis-
play signal levels for direct monitoring.
A signal that meters at 0 on the HD OMNI
will not necessarily clip; use the on-screen
meters in Pro Tools to determine whether a
signal is clipping.
