The transformer is shown for simplicity but can be effected by electronic solutions. Materials Cable (I recommend Mogami, Belden, or Canare) Solder Neutrik XLR connectors (models NC3MXX, NC3FXX (silver) or NC3MXX-BAG, NC3FXX-BAG (black)) Heat Shrink Building the XLR Cables Step 1: Measure and Cut the Proper Length of Cable First, measure the length of cable that you need and cut your cable down to the proper size. Replace damaged connectors on lighting cables that are commonly used for movie and stage lighting, as well as interior building lighting. The circuit assumes a low-Z microphone feeding into a hi-Z amplifier using a transformer for impedance coupling. (Connect one of the L or R pins to shield in the mic plug.) Easy to assemble, simple to use, reliable and robust. Figure 3 shows how to connect an unbalanced mic into a balanced input. Simulate this circuit – Schematic created using CircuitLabįigure 1 and 2 show how to "unbalance" a balanced microphone for an unbalanced input. For an unbalanced microphone one of the mic wires needs to be connected to shield. In this configuration the microphone capsule is wired to L and R and neither is connected to screen. The XLR connector is now a standard for balanced microphone connection. Then with the female XLR connector firmly in the vice, hold the end of the cable and solder the black wire onto the 3 (middle connection as shown), then the red wire on to the 2 connection, and finally the shield wire onto the 1 connection. Originally manufactured as the Cannon X series, by 1950 a locking mechanism was added (Cannon XL) and by 1955 a version surrounding the female contacts with a synthetic rubber polychloroprene insulation using the part number prefix XLR. First manipulate the 3 wires so that they line up with the connector leads.
