BST ADAPT-SPF-SPKF - Female to Female Speakon Adapter

BST ADAPT-SPF-SPKF – Female to Female Speakon Adapter

The BST ADAPT-SPF-SPKF adapter allows two female Speakon cables to be quickly and securely joined together, preserving signal integrity and amplifier power. Designed with two 4-pole female NL4 Speakon connectors, it incorporates a high-strength polymer tube that houses the internal connection of the four conductors, made of 1.5 mm² copper to guarantee continuous current transmission of up to 30 A RMS and 40 A in audio at 50% duty cycle, with a nominal voltage of 250 V AC. Its twist-lock system ensures a firm coupling, preventing accidental disconnections in live and touring environments.
