SPEAKON ASSEMBLY:  You  will  need  a  pair  of  Neutrik  Speakon

®

  NL4FC 

connectors. You will also 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 fittings. See 

Figure 8.
2. Slide the cable tension clip (D) and the speakon coupler (E) through the 

cable end. See Figure 9.
3. Insert each wire with the brass fittings into the top of appropriate slot of the 

connector insert (B) as shown in Figures 9 and 10. Use a 1.5-mm Allen key to 

tighten the connection. See Figure 10.
4. Be sure to properly match the positive (+) and negative (–) leads of each 

wire. See Figure 11.
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.
