Setup guide

Chapter 8: 003 Rack+ Front Panel 67
Monitor Level Control These knobs control the
volume of the Main and Alt Monitor Outputs.
These outputs mirror Analog Outputs 1–2,
which correspond to outputs 1–2 in Pro Tools.
Alternate Input Routing Controls
Aux In to 7/8 Switch This switch routes the Aux
In input pair directly to Inputs 7–8 of Pro Tools,
and does not send it to the Main and Alt Moni-
tor Outputs. This lets you route an alternate in-
put signal (such as a CD player) directly into
Pro Tools without the need to repatch any ca-
bles.
When Aux In to 7/8 is enabled (lit), Analog In-
puts 7–8 are disabled.
3/4-HP2 Switch This switch sets Headphone 2
Output to mirror Output pair 3–4.
Aux In (to Monitor) Switch This switch routes
the Aux In input pair directly to the Main Mon-
itor and Headphone Outputs.
Alt CR (Control Room) Switch This switch mutes
the Main Monitor output and routes the signal
to the Alt CR output.
Mono Switch This switch temporarily combines
Output 1–2 in the Main and Alt Monitor Out-
puts and the Headphone Outputs. This is help-
ful for checking the phase relationships of stereo
material.
Monitor Mute Switch This switch mutes the
Main and Alt Monitor Outputs only, and has no
effect on the Headphone Outputs. Monitor
Mute is automatically engaged when you power
up the unit.
Status Indicators
Host (“1394”) Status Indicator
The Host status LED, marked “1394” below its
LED, indicates that communication has been es-
tablished between the unit and Pro Tools LE
software (or another software application)
through FireWire.
Sync Indicators
The Sync LEDs indicate the current clock source.
When the current clock source is not estab-
lished, the respective LED flashes.
If none of the Sync LEDs are lit, 003 Rack’s clock
source is set to Internal.
There are three Sync LEDs:
W Clk (Word Clock) LED Lights when clocking to
Word Clock.
S/PDIF LED Lights when clocking to the S/PDIF
on the RCA or Optical port.
ADAT LED Lights when clocking to ADAT on the
Optical port.
MIDI Data Indicators
The MIDI Data LEDs indicate the presence of
MIDI data on the MIDI In and MIDI Out ports.
Individual LEDs are provided for each port. Ac-
tive sensing is not indicated.
