Technolink TC-37 Speaker Selector & Input Expander - Multi-Room Audio System for Home Theater & Music Distribution | Perfect for Whole House Audio Setup

This audio system add-on combines a three-way source selector and a stereo speaker switch accommodating two pairs into one compact unit. If your stereo system has fewer source inputs and speaker outputs than you need or want, this model can solve both problems at once. Now you can connect and select between two speaker pairs where before there was only one. One AUX level input port (whether labeled CD, TAPE, AUX or whatever) can now handle three sources. That mini-system, compact office stereo or home theatre system you’ve always wished could do more now can. Add those outdoor speakers you’ve wanted on the patio, connect your TV’s audio without having to unplug something else, or add a way to hear your MP3 player thru your office stereo. Better yet, do all these things at once! See the installation manual PDF (link below) for more info.
