If you can change the PG58-QTR to a  PG58 with an XLR cable end  (maybe by just replacing its cable?), any of the Behringer preamps or mixers will work fine.  That's what I would do.  I suspect that 1/4" plug on mics only work for karaoke machines.

 

The mixers have 1/4" inputs (as well as XLR inputs), but they're "line level" inputs -- they don't go through the mic preamp.  You might be able to get enough gain, though, to drive the DP's "Line In" input.

If I understand, I need a XLR cable (with male and female connectors) to go from the microphone into the mixer.  What kind of cable would I need to then go from the mixer into the line-level, 1/4 inch input in the back of the digital piano?  Would it be line-level 1/4 inch on both ends of the cable or would it have to be XLR on one end?  As I understand, the signal or whatever, from the microphone, has to be converted into a line-level impulse to enable the vocals to go through the piano's amp. and to the speakers.  Is the signal coming out of the mixer line-level.  The piano has two line-level inputs in back and one can be used for another instrument, like a guitar.  Ultimately, the signal has to be made into a line-level impulse.  With respect to vocals, one guy on the Internet talked about using a voice processor (TC Helicon Live Voice) or a "D.I. box", that would make the signal line-level.  Anyway, thanks again for the input--no pun intended.

Charles, thanks for the info.  

I have a Shure PG58-QTR Dynamic Vocal Microphone, with a 15' XLR to 1/4 inch cable.

I plugged in a mic. cable directly into the input in the back of the PX-350 and got only very faint sound.  Can anyone name something specifically, that I can purchase that will boost the sound for vocals to solve the problem?  

Using the Line Level Inputs on the back of the keyboard, is there a way to plug in a microphone, say with some kind of a voice processor or D. I. box (whatever that is),  and use the keyboard's speakers and amp., in lieu of having a separate PA with external speakers and amp., and also to record vocals with the accompaniment?
