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.

To wire the microphone cable to the plug provided, proceed as follows: 
 
1.  Remove the retaining screw. 
 
2.  Unscrew the housing from the pin receptacle body. 
 
3.  Loosen the two cable clamp retainer screws. 
 
4.  Feed the microphone cable through the housing, knurled ring and washer as shown 

Figure 2.

5.  The wires must now be soldered to the pins as indicated in the above wiring tables. If 

a vise or clamping tool is available it should be used to hold the pin receptacle body 
during the soldering operation, so that both hands are free to perform the soldering. If 
a vise or clamping tool is not available, the pin receptacle body can be held in a 
stationary position by inserting it into the microphone jack on the front panel. The 
numbers of the microphone plug are shown in Fig. 3, as viewed from the back of the 
plug. Before soldering the wire to the pins, pre-tin the wire receptacle of each pin of 
the plug.

6.  Be sure that the housing and the knurled ring of Figure 2 are pushed back onto the 

microphone cable before starting to solder. If the washer is not captive to the pin 
receptacle body, make sure that it is placed on the threaded portion of the pin 
receptacle body before soldering. 

 
7.  If the microphone jack is used to hold the pin receptacle during soldering operation, 

best results are obtained when the connections to pin 1 and 3 are made first and then 
the connections to pins 2 and 4. Use a minimum amount of soldering and be careful to 
prevent excessive solder accumulation on pins, which could cause a short between the 
pin and the microphone plug housing. 

 
8.  When all soldering connections to the pins of the microphone are completed, push the 

knurled ring and the housing forward and screw the housing onto the threaded portion 
of the pin receptacle body. Note the location of the screw clearance hole in the plug 
housing with respect to the threaded hole in the pin receptacle body. When the 
housing is completely threaded into the pin receptacle body, a final fraction of a turn 
either clockwise or counterclockwise may be required to align the screw hole with the 
threaded hole in the pin receptacle body. When these are aligned, the retaining screw 
is then screwed into place to secure the housing to the pin receptacle body.
