SPEAKON ASSEMBLY: You will need a pair of Neutrik Speakon
need high-quality two or four conductor speaker cable, a pair of needle-nosed pliers and a 1.5-
mm Allen key to assemble the Speakon connectors to your speaker wire. To assemble the Neutrik
Speakon NL4FC connector, complete the following steps:
1. Strip back 3 /4-inch of the cable casing. Strip off 1
/4-inch from the end of each of the conductors down
to bare wire, and insert the brass fi ttings ( Figure
10).
2. Slide the cable tension clip (D) and the speakon
coupler (E) through the cable end. See fi gure 11.
3. Insert each wire with the brass fi ttings into the
top of appropriate slot of the connector insert (B) as
shown in fi gures 11 and 12. Use a 1.5-mm Allen key
to tighten the connection (Figure 12).
4. Be sure to properly match the positive (+) and
negative (–) leads of each wire (Figure 13).
5. Slide the connector insert (B) into the connector
housing (A), making sure that the large notch on the
outer edge of the insert lines up with the large groove
on the inside of the connector housing. The insert
should slide easily through the housing and out the
other side until it extends approximately 3 /4-inch
from the end of the housing.
6. Slide the cable tension clip (D) along the cable and
insert into the housing (A), making sure that the large
notch lines up with the large groove on the inside of
the connector housing (A). The cable tension clip (D)
should slide easily into the housing until only 3 /8-
inch of the cable tension clip (D) extends from the
back end of the connector.
7. Slide the coupler (E) along the cable and screw it
onto the end of the housing (A). Before tightening,
you may want to test the connector to make sure it
has been assembled properly.
