Analog Inputs
Mic Inputs 1–8
These are balanced, three-conductor XLR con-
nectors for microphone-level analog inputs.
Gain is controlled by the corresponding Input 
Gain Control knob (located on the front panel 
of 003 Rack+). The source (Mic, Line, or DI) is 
chosen using the front panel Line-DI switch.
An unlit Line/DI switch means the mic (XLR) in-
put is active.
Line/DI Inputs 1–8
The combination Line/DI (“Direct Input,” “Di-
rect Inject,” or “Direct Interface”) inputs accept 
both balanced 1/4-inch balanced TRS connec-
tors (for outboard effects and other line-level 
sources) and unbalanced 1/4-inch TS connectors 
(for guitars and other instrument level sources).
Gain is controlled by the corresponding Input 
Gain knob (located on the front panel of 
003 Rack+). The source (Mic, Line, or DI) is cho-
sen using the Line-DI switch. 
An enabled (lit) Line-DI switch means the 
Line/DI (1/4-inch) input is active.

The XLR connectors on Inputs 1–8 are 
wired specifically to match the impedance 
of microphones. Do not use these XLR con-
nectors for line inputs; use the 1/4-inch con-
nectors instead. 
If you have an instrument connected to the 
front panel DI 1 input and you have a line 
or DI input connected to the rear panel 
channel 1 Line/DI input, the front panel DI 
1 input takes precedence over the rear panel 
channel 1 Line/DI input.
