Connect a bare wire speaker system to xbox 360?




Hereru


I have an old 5.1 surround system (at least I think that's what it is--it has five speakers and a subwoofer) which I'd like to try and hook up to my 360. Problem is, it uses bare wire connectors and spring plugs. Are there any kinds of adapters or any possible way to connect it?

I do not have acces to soldering equipment, nor would I know how to use it.

Thanks in advance.



Answer
From your description it sounds like you have PART of a 5.1 sound system - the 5 speakers (+ subwoofer - the "point 1" part), but if they use "bare wire connectors" with spring clips on the speakers to grab the bare wires (not plugs), then you still need a 5.1 amplifier. The Audio Out from an Xbox 360 will not power those speakers, not with any sort of adapter. However, you need a small plane and the first answer is pointing you to a rocket ship to Mars. That is why there are quote marks (") around the word "adapter" - that is NOT any kind of adapter.
If your "surround system" actually does have an amp, all you need is to find out how it gets its signal - Xbox has a variety of outputs - your challenge is to find a cable system from the Xbox that matches your amplifier's Inputs. If you write back with Additional Details describing those inputs, or if all you really have is 6 speakers, either way let us know and we can go from there... Good luck!

Buzzing sound developed on speaker system twice, any ideas as to cause(s) and resolution?

On the ground floor of our townhouse, I have my computer workstation that includes of a large CPU off to the side and two 22" Samsung LCD displays in a semi-circle arrangement. Behind the displays, I have two speakers. These then are flush against an exterior wall. There is a light switch near the speakers of this exterior wall, and a circuit breaker box to the far right (about 3 feet away) from the CPU and monitors.

About three months ago, I noticed the right speaker developed a persistent hum when turned on. Moving its location did not increase or decrease the hum, it remain constant. Part of me wondered if EM interference had altered the speaker, but part of me also wondered if it had just gone bad.

So I replaced the speakers with a different set of speakers. At first they worked fine, but now, three months later, the left speaker has yet again developed a buzzing hum when turned on. The left speaker does not have the hum.

The fact that two different types of speakers both developed persistent humming on the right speaker now makes me seriously concerned about EM interference. Any ideas as to cause(s) and resolution?

Could the Samsung LCD panels cause it? If so, any fixes?
Could the back wall with its light switch and circuit breaker cause it?
Could something be wired wrong within the wall, and if so, how to test and how to fix?

When we first moved in, the circuit breaker had a slight hum associated with the circuit break for the downstairs (associated with the computer) but that went away after a month. But maybe that's connected to this problem?

Many thanks for any advice!
Correction: three months later, the right speaker has yet again developed a buzzing hum when turned on. The left speaker does not have the hum.

Thanks! :-)
Thanks William -- switching the speaker cables still biases it to the original "right" speaker. So it follows the speaker even if you change their locations or change their wired connections. It does not change intensity if you move the speakers. The intensity only changes if you turn up or down the volume (and thus the electronic feed).

I'm wondering if EM interference magnetized the internal parts of the original right-hand speaker, so that when it has a line-feed in, this produces the buzz when it really should only produce silence. Does that make sense?



Answer
Speakers cannot create a buzz. They can only reproduce what is sent to them. Check the inputs to whatever audio amplifier feeds them. To prove that the speaker is not the cause, switch the left & right speaker wires, while you have the buzz, and observe that the buzz changes sides.
A faulty speaker can develop a rattling buzzy sound, but its loudness would track the volume level and would be absent during quiet passages.
