right, now for experts this may not be technical but to me it is because i have no idea what to do, right, heres an image of what i have in mind:
im planning to connect my 7.1 speakers to a 2.0 system (guitar) AND a 7.1 system (PC), now i want the guitar that is 2 channels to play on all of the speakers at 7.1, now i know this will not be true surround but i want it playing on all speakers, but i want this and at the same time the PC staying 7.1, but in my opinion and im sure this is true, if i do connect it like this, all these channels would get connected to each other cancelling out true 7.1 channels, so what could i do to direct these cables instead of going to every channel, only in to the ones i want them to go (in the pc soundcard each cable going to its set cable not in to all cables)
hope you understand this and could help me out
thanks, plz reply
I'm not sure why you would want to do this since it seems like you are making it harder than it needs to be. The easiest solution would be AlphaBeta's where you simply route the signal via the soundcard. On most good modern soundcards the routing will be all handled in hardware so you'll have extremely low latency.
If you still want to wire them directly, then that diagram you posted is almost completely correct. Essentially at that point where you are connecting it all the audio decoding is done and only pure analog signals are being sent down the wires. Therefore wiring the guitar amp in will make the signal simply go to the speakers, as though you plugged in three regular 2.0 sets. You'll just need to remember which side is which when wiring.
The only difference from the diagram is the fact that the center speaker and subwoofer are sent on the same wire, so you'll have to recombine the stereo guitar signals if you want to have the full sound from those two speakers.
thanks webkraller
right, the reason i want to connect directly to output speakers and not the soundcard because these speakers will be my main speakers and i want to connect everything to them, eg tv, pc, guitar, ps3, xbox 360, now i cannot plug them all to soundcard so i want to connect everything to this adaptor im making
and you say the diagram seems correct, but when the guitar cables are connected to ever 2.0 speakers (7.1) wouldnt they all end up connected as one? cancelling out the true surround sound, for example when connected like this, if a signal from the PC was sent to the back left speaker, it would play not to just left back speaker but on all of them...cancelling out the true surround, im thinkin this because the connection of the guitar to all the speakers would connect them all together...am i not correct?
if i am correct what is there i can do to force the signal in to each designated speaker
hope you can understand my confused little brain
lol
another thing you said about connecting the guitar cables with left and right channels to center/subwoofer, so for this do i have to connect it like this:
(guitar cable) inner cables, black (ground), red (left) CONNECT THIS TO CENTER/SUBWOOFER RED AND WHITE, white (right) CONNECT THIS TO CENTER/SUBWOOFER RED AND WHITE
(center/subwoofer) inner cables, black (ground), red (center), white (subwoofer)
would that be the correct connection?
sorry again for my noobyness
Yes, I believe you are right and you may need to throw some diodes in there to ensure directionality.
If you can, test both ways.
Audio circuits aren't exactly my specialty, and hopefully someone with more knowledge can clear up this matter.
As for the wiring for the center and sub, that looks right to me!
Because the sub only handles such low frequencies, don't be surprised if the output is a little wonky when playing a guitar through it.
Well I did a little digging and from what i've gathered it probably would NOT be a good idea to pop some diodes onto the circuit. The most informative link that i've found and substantiated through other sites is Google Answers: Home audio and diodes, electronics
Perhaps you should rethink your design. Instead of constantly active connections, why not assemble the inputs into a sold state switching mechanism?
i could do a switching mechanism but i never done that
but i do learn quick and im sure i would be able with the right research and info ill find
another thing, this circuit i will be making, i want this to be on a circuit board, do you know anywhere i can buy blank circuit boards for this type of circuit?
As for the circuit board question, this doesn't seem like it will be a terribly complex circuit and so I'd probably recommend doing it on protoboard. Its basically a board with evenly spaced holes on it for thru hole components. You can then solder the components directly onto the board and make your own traces quite easily. You can pick that up at every hobby electronics store and probably quite easily online as well. Sometimes people call breadboards protoboards but the ones i'm talking about are just boards with copper squares or circles on it.
After you successfully make the design and then want to revise it for real PCB then i'd suggest BatchPCB. http://www.batchpcb.com/ Great site. Usually takes a little long but its worth the wait for the price.
right as i wasnt so happy with the switch idea (its a good idea but not ideal for me) i asked around, and found out its electric resistors that i need per each channel cable before connecting the cables together, just so everyone knows
hello, right i ave updated this design could someone please check if this is correct?
by the way have a look at the resistors at the center/subwoofer bit, does that work correctly?
because im not sure how resistors work if they can be connected either way, because as i read up apparently they work with the current flow, so when it runs throught the resistor it cannot come back right?
