3. GENERAL DESCRIPTION
Consisting of one Base Unit and two Sub-Units, the NF-2S system is designed to relieve problems
in understanding face-to-face conversations through a partition or face masks. Since the Sub-Units’
built-in magnets allow them to be easily attached to both sides of a partition, they can be used even
in locations without ample mounting space.
4. FEATURES
• Provides full, intuitive support for simultaneous two-way conversation thanks to DSP signal
processing and wideband audio output, while eliminating dropouts in sound output.
• Compact and lightweight Sub-Unit design facilitates installation.
• Magnetically mounted Sub-Units are easily installed, eliminating the need for brackets and other
metal fittings.
• Allows easy connection of commercially available headsets as a replacement sound source for
either of the pair of Sub-Units.
• External control input terminal of MUTE IN allows easy muting microphone for Sub-Unit or Headset
which is connected to input A.
