If the microphone to be used is provided with pre-cut leads, they must be revised as follows.
1.Cut leads so that they extend 7/16” beyond the plastic insulating jacket of the microphone cable (see Fig. 2.)
2.All leads should be cut to the same length. Strip the ends of each wire 1/8” and tin the exposed wire.
Before beginning the actual wiring, read carefully, the circuit and wiring informa- tion provided with the microphone you select. Use the minimum lead required in soldering the connections. Keep the exposed wire lengths to a minimum to avoid shorting when the microphone plug is reassembled.
