I just bought a Tascam US-122 mk-II USB audio interface, and I'm having an odd problem with it. When I plug my electric guitar directly (no amp) in to the line/guitar jack and set the switch to guitar mode, I get some popping/crackling static noises while I play. Not severe, but I can hear them on recordings. If I set the switch to line-in mode and turn up the gain, I don't get any unwanted noise. Is this a common problem with these things, am I doing something wrong, or is my unit defective?
Thanks

I just tried it, but I didn't have any luck.
The whole setup is fairly close to my laptop, although if I move further away it doesn't seem to make any difference. I'll try again later though.
I made a short recording of the problem. Notice the popping at the beginning of each note and the crackling at the end of the last note.

Do you solve it, Klorgnum?
do you have another guitar to test the interface with? also switch out cables, see if that helps any.
but really you're gonna want to mic up an amp or use a modeler anyway, in which case you'd be using line-in or the XLR ins.

when the SIG/OL indicators light up (-30db) the noise starts, when light off noise stops.
I thought it was a power problem and I buy a usb powered hub, but no luck.
Yes I try other cable and a mic instead of my bass guitar.
thanks.
Psygoo: You have the same problem, but when it's set to line in? You should probably just return it to the store, if you can.
thanks.
