Sounds like a compatibility problem going to the unbalanced circuit to me--I don't know Oktava's output circuit, so I can't make a specific recommendation.  Does the PS2 have output capacitors on all leads of the 5-pin (except ground of course)?

That might be it. I remember something I read a long while ago about the Oktava circuit being quasi-balanced. ???

So if it has to do with the signal balancing...is there any way to fix that??

What I'd really like is to just sent this off and pay someone to fix it for me..

i don't think there is anything "wrong" with the ps-2 or the cable(especially since they work with your other mics), you may just not be able to use those mics the way you want to running them into a single miniplug

Would a normal PS-2 with dual XLR outputs and an XLR to 1/8" adapter have the same problem?

I'm guessing that getting this PS-2 to work with my mics is impossible?

Well, I won't need it to work with any other microphones except the Oktavas. Would that make things easier?

I don't remember this cable specifically but i built one other similar with specs i got from the person and it was pinned out this way and it was for a ps-2 as well but with a RA mini xlr. a simple multimeter could tell you this info with a continuity test or send it to me

Shield - Pins 1, 2, and 4
Ring - Pin 5
Tip - Pin 3

I'm confused...what exactly is the purpose of the continuity test? Is it to see if the cable is working correctly?

just tells you if you are passing signal, for exapmle you put one end of the multimeter tester in say pin one on the mini xlr and the other on the shield of the mini plug, you should get a signal, so follow the steps for each pin, so you should get a signal from the shield of the mini plug to pins 1,2,4  then on the tip of the miniplug to pin 3 and ring to pin 5,(thats assuming the same pinout) seeing that it works for the other mic not sure why it would be wired "wrong" though

Ok so then it would seem that mshilarious's explanation is the most likely, a compatibility problem going to the unbalanced circuit. My question is then, is there a way to change the wiring in the PS-2 so that it works with the Oktavas...regardless of whether or not it will still work with other mics?

My other option is to just put it up in the Yard Sale and buy a recorder with XLR inputs.

maybe like i mentioned earlier we could add a ground to the miniplug body like the mbho's need, would be a easy mod, whether it does the trick or not ?

Guess I'll go ahead and list this in the YS.  :-[

don't give up on it yet
place an ISO in the YS to have some one trouble shoot the issue
you might need to send the PS-2 and the Oktava's
but it would be worth it for you...
