WIRING A MALE XLR CONNECTOR
Pans 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 1/2". (No. 8412 cable illustrated here.)
Cut tracer cord, unbraid shield, cut cotton strain
relief cords.
Strip approximately 1/4" of insulation from center
conductors, tin, and trim to approximately 1/8" ex-
posed wire. Then twist shield, positioning it in the
correct orientation to mate with the insert. After tin-
ning the shield, cut it to the same length as the center
conductors.
Solder the center conductors to their respective pins,
using just enough solder to fill the end of the pins.
Yamaha's wiring standard dictates that the black lead
mates with pin 3 and the white (or red) with pin 2
(see footnote on page 10 of this section). Then solder
the shield to pin 1 . Clean any solder splashes and inspect
for burned insulation.
Slide the insulating collar forward, up to the flange of
the male insert. The outer cable insulation 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 firmly grip the cable. Then slide the collar
back into the shell.
Slide the shell forward, orienting its internal keying
channel with the raised lip (key) on 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 cable (No. 8451). The clamp should be turned
around for heavier cable (No. 8412) to provide clearance.
Insert the clamp screws and tighten fully.
