INTRODUCTION
The 291-95 is a small shelf-top infrared repeater assembly designed to reject interference from Plasma Displays from
entering the IR signal line. The 291-95 is the first non fixed-installation version of Xantech's Plasma Series IR product line.
These Small IR Receivers are intended to be placed on a shelf, ledge or mantel in close proximity of a Plasma or LCD
Display. Its small package allows it to even be placed on the top ledge of most Plasma Displays. Besides showing great
immunity to Plasma emissions, the 291-95 (as wells as all Xantech Plasma-Friendly Receivers) work well in the presence
of Sunlight and Fluorescent lighting. Their wide-bandwidth reception allows it to be used with a much wider assortment of
IR Controllable products than the competition assuring the 'job will get done' the first time around without un-wanted
service calls.
