Impedance Matched Speaker Selector
on September 13, 2012
I am a professional Home Theater/Stereo installer. I have a great many customers who have a home theater room, but also a few rooms that they want to run sound to. Unfortunately, most modern AVR's (audio-visual-receivers/amplifiers) do not have the connections or they make the set up exceedingly difficult for non-professionals to figure out how to achieve signal distribution to other rooms/speakers. The SS4 is one of the best and most cost-effective tools to overcome these shortcomings. For instance, if you purchase an AVR with 7.1 sound, you will be able to assign the rear surround speakers of your amplifier to another task like providing sound to other rooms. However, if you simply tap into the speaker posts on your receiver, you are likely to fry your expensive receiver by not matching the impedance of the speakers which you are trying to power. Add a jumper set of wires from the receiver to this selector and you will be able to run up to 4 additional pair of speakers throughout your house without having to buy a separate amplifier. You should use the largest gauge wire for the jumpers possible - usually 12G or 14G. Then all of your runs to your other speakers should also be given the largest gauge wire possible, at least 14G. This will minimize the diminution of volume from splitting the power from your amplifier from a single set of posts to several sets of speakers. The box (SS4) will take care of protecting your amplifier. I like this piece of equipment for it's essential protection functions, ability to turn on/off speakers on a room to room basis, its' ability to provide sound to multiple rooms from an AVR that does not have that capability, and finally its' cost which is exceptional. If you have any questions feel free to contact me for more information.
