LU100WAMP Amplifier is a full featured, wall-mounted amplifier that provides inputs for dry loop 600-ohm telephone page signal and background music source. An automatic level control system limits the output level of the telephone page channel so that differences in the volume of the paging party's voice will be less noticeable. A tone control is provided for optimizing tonal balance for the specific installation. This amplifier includes a built-in night bell that can be triggered by an external contact closure. The night bell mutes the background music, but not pages.
