Analog Outputs
Main Analog Outputs 1–8
These are impedance balanced, 1/4-inch TRS
jacks for line-level analog audio output connec-
tions. Operating levels for these outputs are
fixed at +4 dBu.
While the Main Analog Outputs do accept un-
balanced connections, this may result in a nois-
ier signal than a balanced-to-balanced connec-
tion.
Monitor Section
Main Monitor Outputs
These outputs support balanced TRS, or unbal-
anced TS, 1/4-inch connections. To monitor
your mix, these outputs can be connected to a
mixing board, directly to a monitoring system
(such as a stereo power amp, powered speakers,
or another stereo destination).
The Main Monitor Outputs play the audio that
is routed to analog outputs 1 and 2 from within
Pro Tools, respectively. These analog outputs
feature 24-bit digital-to-analog converters. Op-
erating levels for these outputs are fixed at
+4 dBu.
Monitor gain level is controlled by the Monitor
Level control (located on the front panel of the
003 Rack+).
Monitor output can be muted and the signal
routed to the Alt CR Output with the Alt CR
switch.
Alt Monitor Outputs
These outputs support balanced TRS, or unbal-
anced TS, 1/4-inch connections. These outputs
can be used to monitor your mix through an al-
ternate, or secondary studio monitoring system,
instead of the system connected to the Main
Monitor Outputs.
The Alt Monitor Out Left and Right play the au-
dio that is routed to analog outputs 1 and 2 from
within Pro Tools, respectively. These analog
outputs feature 24-bit digital-to-analog convert-
ers. Operating levels for these outputs are fixed
at +4 dBu.
Monitor gain level is controlled by the Monitor
Level control (located on the front panel of
003 Rack+).
These outputs are enabled when the Alt CR
switch is enabled (lit).
Aux In
These are balanced, 1/4-inch TRS connectors for
connecting alternate audio sources such as CD
players or tape decks. The signal from these in-
puts can be routed directly to the Main Monitor
Outputs (for monitoring) or to Inputs 7–8 (for
direct input into Pro Tools) from the front panel
of the 003 Rack+.
Operating levels for these inputs are fixed at
+4 dBu.
When the Aux In switch is enabled (lit), Aux In
signal is routed to the Main Monitor Outputs.
Audio in Pro Tools that is routed to Analog 1–2
will not be mirrored at the Monitor Outputs.
When the Aux In to 7/8 switch is enabled (lit),
Aux In signal is routed to Inputs 7–8 and does
not pass directly to the Monitor Outputs.
If you plan on connecting Analog Outputs
1–8 to –10 dBV gear, you may want to
place a transformer-based line level attenu-
ator between the 003 Rack+ output and the
input of the destination device to compen-
sate for level differences.
