Need Source for Line Level Switch - Trigger Controlled

[kevkmartin]

I have an application in which I need to switch between 2 line level sources. 
 
In this case, I do NOT want an auto-sensing switch (Such as the Speakercraft LL-One), but rather a switch that will respond to an external trigger voltage (preferably 12v).
 
It will be located in a wiring closet, so no "physical switch", requiring a button press, can be used.
 
I found the Sonance A2L/S online - but it appears to be discontinued.  Does anyone know where these may still be available?
 
Can anyone recommend an alternate product with the same functionality?
 
Thanks for your help!

A relay can't be used for this?  I'm not sure I'm understanding the entire picture.

No, not a relay.  I guess a few relays could be rigged up, but there must be an existing device.
 
I have two devices, both with RCA outputs (L and R).
 
I want to connect both of these devices to two INPUTS on the "Black Box".
 
The "Black Box" also has one set of RCA OUTPUTS, and a 12V trigger.
 
When no voltage is supplied to the trigger, the "Black Box" should route INPUT A to the Output jacks.
 
When trigger voltage is supplied, the "Black Box" should route INPUT B to the Output jacks.
 
This would be the exact product I need.. .If it were available:

Lol you realize that a lot of audio switching gear uses relays inside like this:  http://www.mouser.com/Electromechanical/Relays/_/N-5g31?Keyword=nec+ea2&FS=True

Of course I realize that.  Aesthetically, I'd rather find a "finished product".

Understandable, but hard to beat the price.  And you said wiring closet so should be easy to hide it. 
 
How did this situation come about outside the bounds of an A/V receiver?

I found a solution...
 
The Niles AVS-2.
 
Everything is working great.  I do think I am going to have to add a small Line Level pre-amp to the equation, so I can balance the audio level of the two sources.

You wouldn't want a preamp...that is a quick way to start adding distortion and make the quieter signal too loud (per se)
 
You want a mixer....you use that to control and adjust the gain and levels to make them equal before cascading into the power amp.
