S TEREO A MPLIFIER/ AUTOMATED S WITCHER
Integrating a Niles IR repeater system with a TV plugged
into the current sensed outlet of a TVA50, and a 12VDC
controlled lift mechanism, provides an inexpensive, yet
elegant solution to system automation. (Figure 5) When the
system is in whole-house mode, music from the main system
plays through the in-wall speakers in a room. The TV is hidden
away in the lift cabinet. With a Niles MS100 Microsensor™
inconspicuously mounted in the lift cabinet, and properly
configured for control of the TV hidden inside, the TV power
ON command from an IR remote control, will turn the TV on.
The TVA50 current sensing outlet will detect the change in
current draw, switch the local room speakers to TV and send a
12VDC Trigger OUT to the lift and automatically raise the TV
out of the cabinet...all from just the ON command for the TV!
Turn the TV OFF, the TVA50 current sensed outlet detects the
change, switches the speakers back to the whole-house system
and cuts the 12VDC Trigger OUT causing the lift to lower the
TV back into the cabinet.
