How to connect surround sound speakers to audio system without such outputs

. Monday, April 26, 2010

It was real easy for me to connect my two Pioneer SSP-02 surround sound speakers to my Aiwa NXS-990 mini hi-fi.. Since the main unit comes with two surround sound sockets, what I need to do is simply connect the speaker male connector to them. And the volume of the surround sound can be adjusted together with the left and right speakers by turning the unit volume knob. 

But what happen if your audio system doesn't come with a pair of surround sound outputs?  Don't despair as I'm going to show you how to turn your system into a decent basic surround sound system with very minimal cost.

Your home stereo system would probably have one left and right speakers connected to the rear of the main receiver unit. To setup a surround sound system, you need to connect the positive ("+") terminal of both the left and right surround speakers to the positive ("+") left and right output channel of the receiver unit. Then, connect the negative ("-") terminal of the left and right surround speakers to each other. This complete the current loop of the surround speakers circuit. Note that your system won't output any surround sound if one of the surround speakers is not connected or if you are modifying a monoaural output system.

If you want to adjust the volume of the surround sound, add in a potentiometer with a range of 25 to 200 ohm and a power rating of 3 W anywhere along the surround speaker circuit.

Now, you have a surround sound audio system in which you can add more "umph" to your movie watching and music listening experience.

If you are interested to further enhance your audio system performance, take a look on how to add a center channel speaker to your stereo system. This center speaker is normally placed between the two left and right channel speakers.
