LPF-750: Low-pass Filter

The Nortek Security & Control Family of Brands

The Model LPF-750 Low-pass Filter is used on systems when broadband entertainment feed is supplied by a CATV service. The filter removes all CATV channels above the pass band, allowing insertion of locally-generated ChannelPlus modulated channels. In addition, the filter removes cable system noise which degrades the picture quality of the locally-generated channels.

  • Passes CATV channels 2 to 116
  • Allows insertion of TV channels 65 to 69
