Topic: HD-P2 channels going out

[poppag76]

Hey all.  Having a new issue with my P2.  I have used two different pre-amps with the same result.  The left channel is signifcantly lower than the right channel, about 30dbs.  Both db pads are on due to the psp2's hotness and have check to make sure it isn't just stupidity on my part.  It sounds as if the the preamp isn't working on the left channel at all but it has happened with two different pre-amps so I has to be either the cable or the P2 and the cables are brand new used twice so I assume its the P2.  Don't really have any time to post samples.  Any ideas?

swap cables, if the right channel is then lower you have a bad cable; if not have the recorder checked

with two different pres and brand new cables I'm inclined to think it's the cables - perhaps a bad soldering job on one pin

Its definately not the cables.  The only common link in these two chains is my p2.  Here are the configurations run with the same result, the left channel fuzzy.

WSP 11/27 and 11/28:  Busman mics->monster cable->psp2->kind cable interconnects->HD-P2

Phish 12/5:  AKG483->kind cables->brick->monster interconnects->HD-P2

As you can see everything is different except for the HD-P2.  Does anyone have any ideas?

Sounds like a question for Busman.

I'm not sure you even read what I listed.  The preamps are different, the cables are different and the interconnects are different.

Have you tried running mics straight into HDP2?  Sounds like you'd get the same results, but maybe worth trying?

^^^I think the cables are full length XLR's and the interconnects are either XLR shorties or RCA's.  At least that's what I'm guessing?

Which contradicts what you said (or more importantly, didn't say) in the first post.

If indeed the only thing in common is the P2 then it must be the P2.
Was it the P2 that had reports of the XLR sockets in the deck having rust problems? I know several TSers reported the problem but I don't recall if it was the P2 or another deck. Most of the reports were of rust on the outside but if that happened it could also have occurred inside. Without opening the deck you probably won't be able to tell. If it is a stock unit still inwarranty call Tascam. If it's been modified or is out of warranty call your vendor or Busman.

Hope you figure out what the problem is without having to spend a bundle to get it diagnosed and fixed.

^^^I think it is the P2 that has that "rust" issue or whatever...  I forgot about that.  Hasn't happened to me.....  but I think that I read that it was on the exterior of the box, like the screws or something....  I also think that the person who reported this lived near the ocean and the possibility of salt in atmosphere or something could have been a possibility of the corrosion. 

That thread about the "rust" is somewhere, but I'm not sure where....  might be worth finding and checking if that person had any other issues besides the rust with his deck.

I've just picked one up where one channel lost around 30db intermittently, seemed to be that the pot on the level control was dirty, cleaning it seems to have sorted out the problem

I was the one who first mentioned the rust and it was just a tiny amount of oxidation on the screws. I would check for a cold solder joint.
