 Audio Volume?!
Hey guys, I've got a problem maybe someone here can help me with. I have a pretty good set of headphones I paid 65$-70$ for a couple months ago. Now this headset has three cables on the end. I'm pretty sure it's Right, Left and Center. The problem though is that my sound card doesn't have 3 inputs, just one for mic one for headset and a blue one. I plugged in the center wire to my sound card but it's not nearly as loud as I would have expected. The quality is pretty good but just not LOUD. So, do I need a better sound card or is my headset the problem? Thanks in advance!

 Re: Audio Volume?!
Can you maybe give us the model of the headset so we can ponder your problem better

 Re: Audio Volume?!
This might help get you a little bit of the way if the headphone has colored plugs: http://en.wikipedia.org/wiki/Sound_card#Colour_codes(the blue input is conventionally for line-level input)

 Re: Audio Volume?!
Ok so here are my headphones: Zalman Theatre 5.1 ... http://www.biline.ca/headphones.htmI looked on the back and I have a pink plug (mic i know, but also, people say my mic isn't very loud, even with everything maxed out), I have a black one (center), gray (front?) and dark gray (rear). So my question I guess is which one should I plug in? I have been plugging center since I got it.. Also, If I got a better sound card and could plug all these in, would my sound be louder? Thanks guys!

 Re: Audio Volume?!
What kind of sound card do you have? Normally, you can amplify the sound at a driver-level (or software-based emulator level).

 Re: Audio Volume?!
I'm jsut wondering why you bought a surround sound headset without having a surround sound card. My solution would be to pick up a cheap sound card like this http://www.newegg.com/Product/Product.aspx?Item=N82E16829126005 if you are strapped.

 Re: Audio Volume?!
Whatever you do, don't go to radioshack and buy a 3-to-1 3/8" jack connector and try to connect the channels together. Depending on the circuitry in the headphones, this could really damage them or worse, your soundcard.
(There's a sound reason behind this but instead of boring you with it I'll just tell you that my neighbor tried something like that and blew up both)

I require more than anecdote, fomenta [I typed formenta because I can't read. Clearly there's no "r" in his name, but I'm too dumb to realize that. Please stab me in the face. Also, I just got owned by a wordfilter.]!

A high impedance input allows the source to provide the full-range signal while minimizing the amount of current (and power) transmitted. Connecting three high impedance inputs in parallel creates a single input with an impedance of much less. I'll include the derivation because I get to write siemens: Code: Headphone Speaker Impedance: 50 ohms. Headphone Speaker Conductance: 1/50 siemens = 0.02 siemens.
Conductance of 3 Headphone Speakers in Parallel = 3 x 0.02 = 0.06 siemens. Impedance of 3 Headphone Speakers in Parallel = 1/0.06 = 16.67 ohms.
The impedance dropped to (1/3) of its original spec'd value. The current required (and thus the power required) to drive the speakers will be 3 times what it was before you bridged the channels.
Most output buffers on quality sound cards should be able to drive such a low impedance without damaging themselves (sound quality aside), but for less-than-optimal on-board audio setups, I'd be weary.

 Re: Audio Volume?!
Thank you. ♥
Also, is it regular for you to write seimen? If so, you and Joe Momma should become penpals.

 Re: Audio Volume?!
Montreal, you need a atleast a 5.1 card. If your onboard(or w/e you're using) doesn't have 6 holes then ur F'd. Time to go buy a new soundcard

Oh, it all makes sense now. Alright, so if I get a new soundcard, it's gotta be 5.1. Got it. I don't know why I got these, I don't even like them....
