1. Introduction
The IR Extender and the Repeater Box are two perfect devices for controlling
source equipments over long distance. Through the built-in IR receiver of
IR Repeater and CAT5 cable, users are able to control up to ve source
equipments at the same time that can reach up to a distance of 250 meters
with existing remote controls. There is no space limitation with the devices,
which means even if the source equipments are placed in a different room
or different floor from the display, the performance stays the same. The IR
extender and the repeater box grant users a great convenience, allow users to
control and display their desired source instantly. If however, users only wish to
control the sources within a room area then the IR Repeater Box will be enough
to control up to 2 sources.IR Extender Box is design for long distance and extra
sources control over IR Repeater Box.
2. Applications
TV exhibitions at consumer electronic stores
Home theater installation
Lecture room display
Home entertainment
