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. This secures compliance with the Noise of work Directive from EU (EU Directive 2003/10/EC) and will result in a reduced maximum output level for the user.
