i have torq and a trigger finger...usb 2.0

will i have any latency issues with a cord this long? or should i keep it within a couple feet.

reason being is that im moving and thinking about having my gear set-up differently. instead of having all my gear on two desks right next to each other, was planning on having two desks, but one behind the other so i can just sit in my chair and spin around between dj gear and computer

wonder if its worth it

I don't think you'll have any issues.

Yeah you'll just about be ok with 15ft - latency isn't the problem seeing that an electric signal propagates through a copper wire at about 2/3 of the speed of light (so it can do 15ft in about 15ns, hardly something you're going to notice). The problem comes with signal reflections in the cable, which become more significant with longer cables... because of this the USB standards specify a maximum cable length of 5 metres (about 16ft)

Was going to reply with much of the same information posted by Stu Cox, but I wasn't sure about the max cable length per USB specs (was about to go look it up XD)

I'm an electronic engineer (well, will be when I graduate from Uni...) and I did look it up haha

Are there issues with regular audio cords? I have a 25 foot cord from my computer to my mixer, I can't hear any difference but just curious.

i had about a 10ft rca cable going from my mixer to my external soundcard for recording purposes a while back...and when i had my computer speakers going, there was about a half second delay from my speakers coming out of my master than the computer speakers.

maybe it was my wires, but i couldnt tell you. i would more like to know would getting better quality cables stop that delay from occuring?

^^ that has to do with the latency of your sound card and has nothing to do with the cable.

exactly.

the length on your cables is not the source of you latency issue if we are talking USB or audio cables. the length of you cable will only come into effect when you are talking about electromagnetic interference causing signal loss. otherwise, as our resident electrical engineers have so accurately pointed out, we are talking about nothing more than mere nanoseconds or factions there of.

Yep, your main issue with that length of audio cable will be noise, which actually becomes worse exponentially with length of cable as the longer it is the more noise it picks up (and actually generates itself, as it's a resistive material) across the length of it, but also the signal level drops, reducing the signal to noise ratio.

There's no set maximum length for an audio cable, but the longer your cable the more you should think about noise reduction - using balanced XLR leads and high quality shielded cables, trying to avoid bringing it too close to power leads (and definitely not wrapping it around a power lead), not allowing it to loop or coil, etc.

+1 hehe! compleeting end of next month;majoring in Telecommunications..i also dont think 15ft wud b an issue.

What causes delays in club sound systems then?

Latency from amps/compressors, etc?
