The wiring diagrams included in this section repre-
sent the basic wiring necessary for the most common
types of microphones and other audio inputs. Some
microphones may require extra jumpers or a slight
variation on the diagrams shown.
It is virtually impossible to keep completely up to date
on changes that other manufacturers make to their
products, thus you may encounter a microphone that
differs from these instructions. If this occurs please

Installing the Connector:
1) If necessary, remove old connector from micro-
phone cable.
2) Slide Rubber Boot onto microphone cable with the
large end facing away from the microphone. (See
illustration above.)
3) If necessary, slide the 1/8-inch black shrink tubing
onto the mircrophone cable. (This tubing is needed
for some cables to ensure the cable fits snugly in
the rubber boot.)
4) Use the resistors and connector included with this
kit to configure the TA5F to your particular micro-
phone. A length of .065 OD clear tubing is included
if insulating the resistor leads or shield wire is
necessary. (Remove rubber strain relief from con-
nector backshell by pulling it out of the backshell.)
5) Slide the Strain Relief over the TA5F Insert and
crimp as shown to the right. Then insert the TA5F
Insert and Strain Relief in the TA5F Latchlock.
Screw the TA5F Flex Relief onto the TA5F Latch-
lock.
6) If needed, position and shrink the 1/8-inch shrink
tubing on the microphone cable, then slide the Rub-
ber Boot down over the TA5F connector.

Note: If you use the dust boot, remove
the rubber strain relief that is attached to
the TA5F cap, or the boot will not fit over
the assembly.
