Question: I am running a pair of AKG blue lines (ck91 or 93's) into the PS-2 to the Sony bit mapper. Is there a cheap way to increase the gain I see on the deck levels? (going line in as opposed to mic in) Is there a bench mark test for the three settings on the blue lines? The AKG powers from 9 volt to 48 volt, and I believe the PS-2 only runs them at 9 volt. Any advice welcomed. thanks. Does increasing the voltage supply to the mics enhance the performance?

adding more volts will not give you better performance from these mics

For a while, I ran the 391's into a ps-2 and then to a mod SBM-1. usually, the PS-2 phantom power supply will supply 48V. however, I do know that they made 9V version, so you might have that. regardless, you're question is about gain. The cheapest way to do this is with line transformers. I got a pair at Radio shack for maybe $20. I know Hosa makes some nice ones as well, probably slightly more expensive, but probably better transformers as well. I think I calculated that my RS transformers provided about 12dB of gain. here's a link to a Karl Denson show from the archive that I recorded with this method:

After a few months of running this, I got a Beyer Dynamic MV-100, for phantom power and gain. and I didn't like it as much as the ps-2 > transformers, so I went back to the transformers. the transformers are definitely a nice cheap option for clean gain. I'm sorry I can't reccomend the exact model number for the hosa ones, but I'm sure if you did a search on here for "line transformers" you could find it pretty easily.
hope this helps.

The Hosa line transformers are Mit-176. I also started out using a ps-2 into line tranformers and I got nice levels with them.

frank at cascademedia has the best prices on these. just got me a set of 176's. modded then to have right angle rca's
-
I, too, used to run PS2 > Hosa MIT-176 > modSBM-1. Worked great.

How about putting a pre between mics and sbm-1? Maybe one with phantom power so you can eliminate
the ps-2...

that works too. He did mention that it needed to be an inexpensive solution, and line transformers are certainly the cheapest way to add gain. that's why I think no one has mentioned a preamp yet.

Thanks for info everyone. The line transformers seem the best at low end, what would you guys run if i went with a pre and can't afford a v-3 at the moment. Also, clarification on the voltage issues, it doesn't matter if you power these with 9 or 48, same result?
Appreciate it.

I ran the blue lines with a MP2>Mod SBM1 with good results...sounded great....that combo gives you a nice warm sound...before the MP2 though I ran the AT CP8201 transformers with the B18 (phantom power boxes) into a mod sbm1 and I thought that the only difference was that the transformer based recordings (vs the MP2) were a little thinner on the low end....not bad...just a slight difference....and when you tape a bassy ass rock show...sometimes thinner on the low end is a good thing, because the MP2 can overemphasize at times...
