The UI 770 is the ideal universal wideband Interface box which allows the user to connect a PC, standard phone, handset, a headset of the Sennheiser contact center or office series and even a dictaphone for voice recording.
With the UI 770 you can easily switch between the headset, handset and PC, adjust the volume of the headset speaker and mute the headset microphone. The UI 770 supports the possibility of limiting the speaker volume by simply setting a switch.
