If the microphone to be used is provided with pre-cut leads, they must be revised as follows :
(i) Cut leads so that they extend 7/16" beyond the plastic insulating jacket of the microphone cable.
(ii) 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 information provided with
the microphone you select. Use the minimum head required in soldering the connections. Keep the
exposed wire lengths to a minimum to avoid shorting when the microphone plug is reassembled.
