I have a question for anyone who may have the Logitech Z-10 Interactive speakers (or similar).
They say they connect audio information from the PC via USB. If so, how does the sound card work; i.e., there is all manner of clever audio stuff going on, which ends up at the line output of the card. This is then normally connected to an amp/speaker system. How does USB bypass this process, but still use the facilities of the audio card?
Aww…come on guys, doesn’t anyone know how they work??!! I think one of you should buy some and provide me with a report:-))
Other stuff on USB makes sense because a lot of it relates to data that is floating around the computer’s buses (memory sticks in particular); but I thought (wrongly?) that sound data started out that way, but was processed by the sound card to emerge from its line/speaker terminals (so “basic” sound may be there, but not the processed sound).
I mean, if I saw that you could connect a monitor via USB, I’d have to ask how the clever graphics card stuff ended up on the USB system; isn’t sound similar?
Oh, Arthur S, I think you need to tell your wife they are an essential upgrade to keep your system safe...can't argue with that!!
I understand the "active" part; typically, one of the "speakers" also includes an amplifier powered via the mains adapter. Indeed the ones I am using currently do just that. The difference is that my current ones are plugged into the output from the sound card, so all the clever sound things will end up in the amp/speaker (actually a waste, as my curent ones are of poor qualtiy, hence the interest in new ones).
My problem is understanding how the clever sound stuff gets into the USB system, rather than (as well as?) the sound card's line output.
Nicam etc, also has digital processing (which I am happy with), but again the output of the digital processor goes into the TV's sound amplifiers (or to an external AV amp) and hence to the speakers. A clear and understandable path.
phono: I take it that you ONLY connect your speakers to your USB port (and a mains adapter I guess). Did the speakers come with any software?
If so, it definately looks like the sound is in the USB somewhere!
Hmmm...my simple question looks a bit more complex after all!
