i originally posted this in the archive section under the active cable post there, but this is probably a better spot to get help on the subject...
so i've been slacking today at work and looking at actives and such. in my hunt to see if you could make your own...i discovered
thislooking at this
the BUF634 in the middle can be used inside the feedback loop of op amps to increase output current, eliminate thermal feedback and improve capacitive load drive. It seems like a cable with this attached going from the cap to the body would boost the cap enuf to have it be away from the body.
so you'd end up with a cable with this in the middle
which really doesn't seem like it'd be that bulky if you could make your own active cables for less than $100.
i guess what i really need to know is what is it that actives do. they have to be more than just cable. and it seems like if a person had enuf electrical skills they could make their own. are there any active cable specs out on the net? even user manuals might help that came with the cable/mics. if i could figure out what it is they do exactly, it might be easier to figure out what i should be looking for to make my own. any specifications or schematics would be helpful too.
if its just a cable, why wouldn't any cable work...could you just have a regular cable and have them be "passive" cables. seems like if the booster didn't introduce noise that they'd work.
