Band Zoning
W8LM band zoning is from the bottom upwards as follows:
Low-mid frequencies
Bottom 4 cabinets in the lower zone
The rest of the cabinets in the upper zone
High frequencies
Bottom 4 cabinets in the lower zone
Up to 4 cabinets in the middle zone
The rest of the cabinets in the upper zone
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). The old U.S. standard was never XLR, it was XRL!
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.
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”.
