because one extra mid frequency band and two extra high frequency bands drive
the upper zones of the line array.
Our standard W8LC presets configure the DX1 to produce these extra bands. This
requires 6 outputs; 1 x LF, 2 x MF, 3 x HF.
How do I patch my racks to take advantage of
standard W8LC controller presets?
Standard W8LC presets configure DX1 outputs for the following controller-
to-amplifier patches:
DX1 system controllers outputs are configured and patched as follows:

DX1 controllers have fully balanced inputs and outputs and MA series amplifiers
operate with pin 2 hot. Racks will therefore be pin 2 hot – assuming that I/O panel- to-
DX1 input and DX1 output-to-MA series amplifier input cables are wired 1-to-1 (X),
2-to-2 (L), 3-to-3 (R).
Standard balanced & screened XLR cables (typical spec = 70 ohms/1000m, 150pF/m
core-core, 300pF/m core-core+screen) should be used between the panel and the DX1
input and between DX1 outputs and MA series amplifier inputs. Good EMC practice
requires that XLR cable screens should be connected at both ends.
W8LC loudspeaker pin-out and cabling information appears later
Please note that the D-Sub connector on the rear of the DX1 is for loading Martin
Audio control presets only. It does not facilitate PC equalizer control "on the fly".
