To wire the microphone cable to the plug provided, proceed as follows:

Remove the retaining screw.

11 

Unscrew the housing from the pin receptacle body.

21 

Loosen the two cable clamp retainer screws.

31 

Feed the microphone cable through the housing, knurled ring and 

41 

washer as shown Figure 2.

Before beginning the actual wiring, read carefully the circuit and wiring 

information provided with the microphone you select. Use the minimum 

heat required in soldering the connections. Keep the exposed wire 

lengths to a minimum to avoid shorting when the microphone plug is 

reassembled.             

ALTERNATE MICROPHONES AND INSTALLATION

For best results, the user should select a low-impedance dynamic 

type microphone or a transistorized microphone. Transistorized 

type microphones have low output impedance characteristics. The 

microphones must be provided with a four-lead cable. The audio 

conductor and its shielded lead comprise two of the leads. The third 

lead is for transmit control and fourth is for receiving control.

The  microphone  should  provide  the  functions  shown  in  the 

schematic below.

If the microphone to be used is provided with pre-cut leads, they must 

be revised as follows.

Cut leads so that they extend 7/16" beyond the plastic insulating jacket 

11 

of the microphone cable.

All leads should be cut to the same length. Strip the ends of each wire 

21 

1/8" and tin the exposed wire.
