I suggest looking at these switches available thru Mike at Tradertrax.com before you buy.
I recently needed to auto switch between three active optical inputs and Mike went to a significant amount of trouble to research my application, configuration and needs. He came up with a 3X1 auto sensing optical switch which also comes with a remote control so that it not only selects the active input but if (as in my case) all inputs remain active concurrently, the end user can select the preferred input with a credit card sized remote control.
The one I purhased was a 3x1 A/V switch from Shin Kin in Taiwan for $85.00+shipping. Mike also has a 4x2 optical switcher for $89.95 from the same manufacturer.
