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
Mic inputs:
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
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.
RCA sockets for use with tape recorders etc., signal = main mix. Use
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
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
