WIRING A FEMALE XLR CONNECTOR
Parts identification (as the connector is usually
packaged).
Insert strain relief in rear of shell. Then slip shell
onto cable end, followed by insulating collar. Strip outer
insulation approximately 9/16". (No. 8451 cable illus-
trated here)
Pull off foil wrap. Strip approximately 5/16" of
insulation from the center conductors, leaving approxi-
mately 1/4" of insulation between the bare wire and
the outer insulation. Tin the center conductors, and
trim so that about 1/8" bare wire remains. Then tin the
shield conductor, orienting it with the center conduc-
tors so they are aligned with the proper pins of the
insert. Cut the end of the shield so that it extends 1/16"
beyond the center conductors.
Solder the center conductors to their respective pins,
using just enough solder to fill the end of the pin.
Yamaha's wiring standard dictates that the black lead
mates with pin 3, the white (or red) lead with 2 (see
footnote on page 1 0 of this section). Then solder the
shield to pin 1 . Clean off any solder splashes, and inspect
for burned insulation. Insert the locking tab in the
female insert, as illustrated, with small nib facing front
of connector.
Slide insulating collar foward, up to rear edge of
female insert. The outer insulation of the cable must be
flush with, or covered by the end of the insert. If any of
the center conductors are visible, the cable clamp may
not be able to grip the cable firmly, and the connector
leads will soon fatique. Then slide the collar back into
the shell.
Slide the shell forward, orienting the notch in the
shell with the locking tab in the insert. Secure the insert
in the shell with the set screw. Place the cable clamp
over the rear of the shell, with careful attention to the
clamp's orientation; a raised lip inside the clamp should
be aligned immediately over a lip in the shell for thinner
cables (No. 8451). For heavier cables (No. 8412), the
clamp should be turned around to offset the lips and
provide more clearance for the cable. Insert the clamp
screws and tighten fully.
