Connecting speakers to a receiver?

Tech Dude

I know of a building that has a sound system, with over 30 speakers on the ceiling. In the sound system, there are many speaker cables, but one going into the receiver. How could there be so many speaker cables, but only one or two going into the receiver? What device is used to do that? Also, there were microphone jacks in the wall, with about 4 going into one input. How do they set it up that way?

Answer
Sounds like amature wiring. The speaker cables are probably spliced together before reaching the speakers.

The microphone jacks all being connected to one input will work, but the quality will be lacking if more than one microphone is used at a time.

With over 30 speakers in the ceiling all in the same set of outputs, there is likely to be impedance problems, which can result in fuses being blown if the wrong amplifier is used.

Its probably not worth fixing if it's broken. I would reccomend consulting a professional about replacing the system. Equipment for a large system like that is not going to be available at consumer electronics stores.

When i connect speakers to my system and microphone ..i'm getting noise thorugh the speakers ..?

surendrana

how do i make sure that this shud not come when both are connected .i.e speakers and microphone
in fact connected speakers and microphone to my system..

Answer
What it is doing is that the mic. is taking the sound from what your computer is making, and it is taking it and pushing it through the speakers. I had the same problem, what I did is I moved the speakewers away from the mic. Or you might have to unplug the mic if you want to use your speakers, but that is worthless. I hope that will help you.
