Open Duplex

Open Duplex is a technology that allows simultaneous communication between two active parties on an intercom system.

With Open Duplex, both the speaker and microphone on the stations are active at both ends at the same time, effectively making one-at-a-time intercom communication obsolete, and allowing for free-flowing, clear and reliable communication.

After years of active development Vingtor-Stentofon has achieved a world’s first effective Open Duplex capabilities at output levels of up to 95dB. Whilst Open Duplex is not new, it has never been successfully implemented at levels above 95dB, strengthening Vingtor-Stentofon as the global leader in critical communication.
