Most intercoms impose physical constraints upon its users, whereby a person must stand close to the station in order to be heard clearly.

The software algorithm developed by Zenitel allows the station to automatically adjust the gain on the speaker’s voice, effectively maintaining a constant volume level to the receiver, regardless of the speaker’s distance from the station. The station is capable of handling audio from a distance of up to 7m.

This implementation drastically increases the stations usability and improves safety, as not only are the speaker’s hands free, but they are also no longer restricted to the remain within a close proximity of the station.
