This is a Neutrik “combo” input connector that ac-

cepts either a balanced male XLR connector or a 1/4" 
balanced or unbalanced connector. Professional mics 
usually have XLR connectors, while consumer or semi-
pro mics often have 1/4" connectors.

The mic input signal is routed through the mic input 

section, mic EQ, and then to the main mix bus.

These RCA jacks accept a stereo line-level signal from 

a CD player or other line-level playback device, such as 
an MP3 player.

These RCA jacks accept a stereo phono-level signal 

from a turntable (when the line/phono [4] switch is 
pushed in), or from a line-level playback device such as 
a CD player or MP3 player (when the line/phono switch 
is out). Check that your turntable has a phono-level 
output and a moving-magnet cartridge.

If you connect a turntable with phono-level outputs 

to the line/phono inputs [3], push this switch in to 
select the phono-level input stage, which includes an 
RIAA preamp for proper re-equalization of the incoming 
phono signal.

If you are connecting a line-level playback device like 

a CD or MP3 player, leave this switch out to select the 
line-level preamp.

Do not press it in if you have a line-level 
signal connected.

These terminals are provided to connect a ground 

wire from your turntable(s) to the d.2 Pro. Most turn-
tables provide a ground wire to connect to the preamp 
for the purpose of eliminating “hum” in the audio signal. 
Simply turn the ground terminal on the d.2 Pro counter-
clockwise to loosen it, wrap the end of the ground wire 
clockwise around the terminal, and hand-tighten the 
ground terminal for a secure ground connection.

These 1/4" TRS jacks provide a balanced line-level 

output signal from the stereo FX Send bus. Use these to 
connect to the inputs of an external effects processor. 
You can also use an unbalanced 1/4" TS connector.

These 1/4" TRS jacks accept a balanced line-level 

signal from an external effects processor. They will also 
accept an unbalanced 1/4" TS connector.

If you are using a stereo effects processor, connect 

its left and right outputs to the corresponding left and 
right FX return jacks. If it is a mono effects processor, 
connect its output signal to the left FX return jack, and 
it will appear on both the left and right main mix bus. 

These 1/4" TRS jacks provide a balanced line-level 

signal from the main mix bus, prior to the rotary main 
level control [32]. Use these to connect to a pair of 
powered monitor speakers (or to the inputs of an ampli-
fier powering the monitor speakers in the booth). If you 
only have one monitor speaker, just use one of the booth 
outputs and push in the booth stereo/mono switch [34] 
in the control section on the top panel.
