Keep Your 1/4" Cables! This clever adapter lets you connect to any power amp or speaker cabinet that has a Speakon jack, without cutting off the ends of your 1/4" cables to rewire them. Simply slip the 1/4" end onto your speaker cable and the Speakon (4-pole) end can be plugged into the amp or cabinet. Adapts from NL4FC to 1/4 Inch 2-pole jack, wiring: +1 to TIP and -1 to SLEEVE. The new SPX-Series Speakon Adaptor NA4LJX replaces the NA4LJ. The improved design is more rugged and the rated current has been increased to 20 A.
