APPENDIX A: COMPOSITE CABLE
To assemble a composite loudspeaker cable:
1. Cut the bulk cable to the desired length, including fanout length.
2. Strip the outer jacket to the desired fanout length.
3. Remove excess binder.
4. Strip 0.7 inch (18 mm) of the jacket from each of the two signal pairs.
5. Unwind each shield, then twist to form a third conductor.
6. Trim the foil shield and rod fillers of each signal pair so they sit flush with the jacket.
7. Strip each conductor of the two signal pairs by approximately 0.16 inch (4 mm).

8. Tin exposed conductors and then solder to the XLR connector using the following wiring scheme.
Composite Cable Signal Pinout (XLR)
Type
XLR 3-pin (Balanced Audio)
and Weidmuller (RMS)
Two pair; XLR 5-pin
(Balanced Audio and RMS)
CAUTION: When wiring cables for the MDM-832 AC outputs, it is extremely important that each pin in the con-
nector be wired correctly, to avoid damage to the loudspeaker. In addition, make sure that audio pins are wired
correctly; polarity reversals for audio signals affect system performance. RMS connectors are polarity insensitive.
NOTE: For RMS connections in systems with XLR 3-pin audio connections, terminate the second audio pair
with Weidmuller RMS connectors according to the RMS Connector Assembly Instructions (PN 28.033.060).
For RMS connections in systems with XLR 5-pin audio connections, terminate both signal cable shields to pin 1.
