Mic/processor/board question

Hey electronic deities... :D

I have a Behringer B-1 condenser mic plugged into a Behringer UB 1202 board. The mic needs phantom power, which the board supplies. My question is: I just acquired a Behringer AutoComPro MDX 1400, and was going to use it as a mic processor. Can I plug the mic into the MDX, then the MDX into the board without damaging the MDX with the phantom power? Or should I just leave the MDX out of the loop because of said phantom power? Thanks!
 
The MDX1400 can't power the B-1. So you will need to leave the B-1 plugged into the 1202 and hood up the MDX1400 through one of the "effects loops" on the board.
 
Why, thank ye, kind suh...

I originally had plugged the mic into the MDX, then ran a cable from the MDX into the board. At that point it occurred to me that turning phantom power on would shoot 48 volts into the MDX. I stopped there not knowing whether said 48 volts would fry it. Hence, my question. Now, if you'd be so kind, please explain how to do what you just described (sorry, I'm not an engineer).

Thanks again...
 
Your mixer has an Effects Send (usually marked FX). You connect the output of the send for the mixer channel with your mike into the input of the processor. The output from the processor goes back to the FX in for that same channel. There is usually a level knob for the FX send in the line of knobs controlling the EQ and Padding etc above the main fader of the channel. You will need to use that to get an adequate feed to the processor. If you don't have the manual for the board you can download a PDF file from: http://www.behringer.com
 
Actually, you'll want to place the processor on that mic channel's 'channel insert' using an insert cable (typically a 1/4 inch TRS to two 1/4 inch jacks or RCA jacks for both the send and receive paths). Using an effects send, unless it's set to bypass the channel completely in a 'pre fader' mode, will not work. You'll have a mix of processed and unprocessed audio, which you probably don't want.

Your particular console does not have channel inserts, unfortunately. Also, each channel's efx send is post fader, so you couldn't just send audio from the efx send to the processor and back into another channel input, having the mic channel turned down and it's efx send feeding the Autocom, in which the Autocom will come back into the board on another input channel.

You *could* take the left and right master outs of the 1202, go into the Autocom's left and right inputs and route the left and right outputs of the Autocom into your recording device. Only problem with this method is that all of your audio sources will be processed, plus you won't be able to monitor the processing from the Autocom directly (unless your recording device allows you to monitor in real time, in which case you could take the outputs of the recording device, route them into the 'TAPE IN' of the 1202 and use the 'TAPE TO CTRL ROOM' monitoring option to hear yourself).

In the long run, you'd be better off investing in a good mic preamp with phantom power built in. There's a few good models out there, which I am sure our other folks on the board could recommend some good products at a reasonable price.

You are correct, I was thinking of situations when I had used the effects send to an external reverb unit and that was to be mixed with the unprocessed audio. The purchase of a processor with phantom power would be best and less complicated. The patching needed to use the one you have would created a mess with the risk of unprecidcted results just when you need it least.
