I've had little faith in the 'Pyle' brand, but it certainly looks like an interesting solution.
 
At some point my kid's going to want to play music in the bedroom.  I'd like to find a reasonably-priced way to do it with our centralized Russound CAV66 setup.  This might be worth trying.
 
Anyone else used any local bluetooth-back-to-WHA setups?

Oh, my mistake. I'm using the switch with the built-in amp, the LSA (Local Source Amp).

I don't know if these switch devices can be used with other control systems, but the LSA has worked well for several years, in 2 locations, with my Nuvo system, where I am not using an AVR. The LSAs amplify the 3.5 mm audio headphone output, from the TVs, switching to the Nuvo input when that voltage is sensed from the KPs.
