In summary, Io Audio Technologies' Speakerlatch™ cable and chassis connectors bring dependability to speaker level connections with crucial safety and performance upgrades. They feature a “twist-to-lock” locking mechanism that guarantees a proper connection and virtually eliminates the possibility of accidental unplugging. Additionally, all four contacts are hidden inside the reinforced plastic housing, making it impossible for the user to inadvertently touch energized parts. These cable connectors also feature distinct keying patterns that prevent the user from connecting a speaker level line into anything other than a Speakerlatch panel mount connector. Speakerlatch connectors all carry UL approval to provide safety assurance.
