EURODESK MX2442A
7.2 EURODESK MX2442A Patchfield and Plug Wiring Scheme
Most of the inputs (inserts being the major exception) are balanced.
+
Unbalanced equipment may be connected to balanced inputs/outputs. Either use mono 1/4"
jacks or connect ring and barrel of TRS jacks (or pin 1 and 3 of XLR plugs).
Mono input channels 1 - 16
Insert points: unbalanced send and return on a single 1/4" TRS socket, wired tip = send, ring = return, sleeve
= ground/screen.
Line inputs: balanced 1/4" TRS sockets, wired tip = hot (+ve), ring = cold (-ve), sleeve = ground/screen.
Mic inputs: XLR-type connectors, wired pin 1 = ground/screen, 2 = hot (+ve), 3 = coid (-ve), for balanced
low-level operation.
Stereo input channels 17 - 24
Four stereo pairs. Unbalanced 1/4" TRS sockets, wired tip = hot (+ve), sleeve = ground/screen.
Aux sends
Unbalanced 1/4" TRS sockets, wired tip = hot (+ve), sleeve = ground/screen.
Stereo aux returns
Two stereo pairs on balanced 1/4" sockets, wired tip = hot (+ve), ring = cold (-ve), sleeve = ground/ screen.
Subgroup inserts
For inserting into a subgroup signal. Unbalanced send and return on a single 1/4" TRS socket, wired
tip = send, ring = return, sleeve = ground/screen.
Subgroup outputs
Primarily designed for feeding a multitrack recorder. Unbalanced 1/4" TRS sockets, wired tip = hot (+ve),
sleeve = ground/screen.
2-track in-/outputs
RCA sockets for use with tape recorders etc., signal = main mix. Use custom-made RCA cables for the
2-track in/out traffic (center post = signal (+ve), sleeve = ground/screen).
Monitor & control room outputs
Will feed a pair of speakers (via an amp, of course). Balanced 1/4" TRS sockets, wired tip = hot (+ve),
ring = cold (-ve), sleeve = ground/screen.
Phones outputs
Will feed two headphones. 1/4" TRS socket, wired tip = left signal, ring = right signal, sleeve = ground/screen.
Main inserts
For inserting into the main mix signal. Unbalanced send and return on a single 1/4" TRS socket, wired
tip = send (out), ring = return (in), sleeve = ground/screen.
Main outputs (TS sockets)
Unbalanced 1/4" TS sockets, wired tip = hot (+ve), sleeve = ground/screen.
Main outputs (XLR)
Balanced XLR, wired pin 1 ground/screen, pin 2 hot (+ve), pin 3 cold (-ve). Maximum level is +28 dBu.
7.3 Audio Connections
You will need a lot of cables for different purposes. On the next page you will find some figures to make sure
you have got the right ones.
+
All outputs are ground-compensated (decoupled from the mains supply earth) to eliminate the
possibility of ground loops.
+
Please make sure that every part of your equipment is connected to the mains earth. To avoid
any risk of electric shock never disconnect the mains earth from any part of your equipment!
+
Please ensure that only qualified persons install and operate the EURODESK. During
installation and operation the user must have sufficient electrical contact to earth.
Electrostatic charges might affect the operation of the EURODESK!
