EURORACK MX2004A
AC Power In. For connecting the mixer to the power supply unit (PSU). Always connect mixer and
PSU before you connect the PSU to the mains supply.
POWER switch. Once the PSU is connected to the mains supply, you may switch on your EURORACK.
Allow one minute after powering up for the system to equilibrate before setting input gains.
PHANTOM switch. When using condenser microphones, +48 V DC can be switched globally on or off
for all microphone channels.
+ Care should be taken not to plug microphones into the console (or stagebox) while the phan-
tom power is on. Also, mute the monitor/PA speakers when turning phantom power on or off.
Let’s now have a look an all the inputs and outputs on the EURORACK. Most of them are balanced.
Unbalanced equipment may be connected to balanced inputs/outputs. Either use 1/4" phone connectors or
connect ring and sleeve of 1/4" TRS connector (or leave pin 3 of XLR plugs unused).
Main outputs (XLR)
Balanced XLR, wired pin 1 ground/screen, pin 2 hot (+ve), pin 3 cold (-ve). Maximum level is +28 dBu.
MAIN OUTPUT LEVEL switch
Level to the XLR main outputs (+4 dB) will be lowered to microphone level, if you depress . E.g. you
can route the lowered output signal directly to the microphone inputs of another console.
Main output
Unbalanced 1/4" phone connectors, wired tip = signal, sleeve = ground/screen.
Alt 3-4 output
Unbalanced 1/4" phone connectors, wired tip = signal, sleeve = ground/screen.
Let us now move onto the front panel of your EURORACK MX2004A.
Mono input channels 1 to 8
Mic inputs
Balanced XLR, wired pin 1 = ground/screen, 2 = hot (+ve), 3 = cold (-ve). Remember the PHANTOM
switch .
Line inputs
Balanced 1/4" TRS connectors, wired tip = hot (+ve), ring = cold (-ve), sleeve = ground/screen.
Stereo input channels 9/10 to 15/16
Four stereo pairs. Balanced 1/4" TRS connectors, wired tip = hot (+ve), ring = cold (-ve), sleeve =
ground/screen.
Stereo aux returns 1/2
Two stereo pairs. Unbalanced 1/4" phone connectors, wired tip = signal, sleeve = ground/screen.
Aux sends 1/2
Unbalanced 1/4" phone connectors, wired tip = signal, sleeve = ground/screen.
2-track in/out
RCA connectors for use with tape recorders etc., signal = main mix.
Control room outputs
Will feed a pair of speakers (via an amp, of course unbalanced 1/4" phone connectors, wired tip = signal,
sleeve = ground/screen.
Phones outputs
Will feed headphones. 1/4" TRS connector, wired tip = left signal, ring = right signal, sleeve = ground/
screen.
8.2 Connections
You will need a lot of cables for different purposes—see the following figures to make sure you have the right
ones. Unbalanced equipment may be connected to balanced inputs/outputs. Either use mono 1/4" phone
connectors or connect ring and sleeve of 1/4" TRS connectors.
