Suggestions for use beside extra speakers?! Surround Sound, possibly?
Answers: Ohms matter. Impedance, expressed surrounded by Ohms, is the "resistance" (or load) the amplifier "sees". If you were to try and connect more than one speaker per output in that are a few things you should be aware of...
If you were to "daisy chain" them, or more precisely, connect them contained by parallel, the amplifier would "see" 2 (two) 8 Ohm speakers as 1 (one) 4 Ohm speaker. Parallel halves the impedance, which may seem close to a good article, and it can be, at times. First of all the amplifier can output more wattage, but unprotected in mind that it is also more taxing on the amplifier to supply power to lower impedances (i.e. 4, 2, 1 Ohms).
Many consumer geared amplifiers (and receivers) can feel 4 Ohm loads, though they are designed for 8 Ohms, which is way most consumer base loudspeakers are 8 Ohm.
There is another way to flex multiple speakers to the same output which is call "series". When wired in series 2 (two) 8 Ohm speakers become 1 (one) 16 Ohm speaker. It is the conflicting of parallel in that it doubles the impedance.
To telecommunication in parallel:
You can do so contained by by wiring the first speaker as you usually would, and take another speaker cable and connect the second speaker to the first speakers inputs, positive "+" to positive "+" and denial "-" to negative "-". Or you can run two speaker cable to each speaker from the amplifiers output.
To line in series:
First you connect one speaker lead between the positive "+" output of the amplifier to the positive "+" input of the first speaker. Second, take another speaker flex and connect it to the negative "-" input of the first speaker and connect it to the positive "+" input of the second speaker. Third, you help yourself to another speaker wire and connect it to the cynical "-" input of the second speaker and run it back to the refusal "-" output of the amplifier.
Of course all above examples be for 1 (one) channel of the amplifier, right depression for example.
Also there is what is call "Matrix" it is a way to chain in a flipside surround channel into (or out of) a stereo amplifier...
I haven't done this contained by years, and hopefully I remember it correctly (I believe I have)...
It is very much similar to wiring within series, except that you connect the second speakers negative "-" input beside the left channel negative "-" output, assuming you started electrics the speakers at the right channels positive "+" output. It within effect nulls the "center" signal (what both channels would produce within a stereo setup) and you hear just the "left" and "right" audio signal, albeit contained by mono. It's basically what Dolby Pro Logic did formerly the advent of 5.1 digital surround encoding.
If you try any of these wiring setups, be aware of the potential consequences...
over driving you amplifier and ruining it. So read the connected .pdf article below for better insight into the series/parallel business (it's for car audio applications but applicable).
Any question e.mail be or include to your question...
Good Luck
