Sennheiser UI 770 Wideband Active Interface Amplifier PC and Phone Switch
UI 770 is a universal wideband interface box which allows the user to connect a PC, standard phone, handset, a EPOS headset and even a dictaphone for voice recording. With the UI 770 you can 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 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. Features include dynamic volume control to prevent sudden noises, sound clarity to enhance the caller's voice, compatibility with both wideband and narrowband headsets.
