quick question - i have a mackie 16 channel, i've noticed both my phone jacks are coming through with unbelievably static. i've had the board for about 2 years now, relatively moderate use, and this is the first time i'm encountering this...do these things require heavy cleaning, could it be dirt causing this, or is it something serious that i need to look into?

i rearranged my studio equipment and that's when i noticed this, my first reaction was maybe the wires (maybe even the board's placement to the PC), then the headphones, but all those checked out ok, which leads to the jacks themselves...any help would be great, i NEED these headphone jacks...
 
do you have an audio wire close to an electrical wire, or mabye its grounding. Try plugging your mixer into a different outlet.
 
thanx, i'll give that a shot tonight...i'm hoping that's what it is, i did change outlets during the move...
 
By static do you mean hum, hiss, white noise, clicks and pops?

Try a little DeOxit in the jack and the headphone level pot. Check the solder joints on the jacks.
 
it seems to be a combination of white noise and a strong hiss...would rubbing alcohol work as a solvent?
 
That doesn't sound like dirty connectors... I think you may have miss-hooked some cables after the move... or broken some... I'd recheck your cable routing and reseat all connectors while monitoring through your phones...

Does you master or tape out buss sound the same? or just the phone jacks?
 
just the head jacks so far, everything else is still crystal...
 
I just rechecked all the connections...it seems fine, I even moved some amps and equipment around thinking it could be some magnetic interference...still nothing. I hear the fuzz more on the right speaker than the left.
 
Don't know what else to tell you... just sounds highly suspect that the problem started after you moved the board.

It could be the headphone amp internal to the board... or the internal connections...
 
I tried moving it around this weekend, still nothing...would rubbing alcohol be safe to use as a cleaner?
