Does anybody make a Mic A/B box?

[pjmuck]

I'm looking for a simple A/B box that will accept two or more mic inputs (preferably with phantom power) that can be output to one or more outputs. The idea being that I'd like to be able to use a single vocal processor that only has 1 mic input on two different vocal feeds (lead and backing vocals), so that clicking on the A/B box switches between the two mics/inputs. Any suggestions?

Definately not a good idea without some active electronicsm since switching differential signals (ESPECIALLY with phantom power) will create a pop that, along with the gain of the mic preamp, could damage speakers in a hurry.

 

Why not just use the mixer's post fader aux bus?

 

To do this properly requires a pair of mic preamps, and switching the single ended line level output rather than trying to do so on a balanced mic level line.

 

I can think of several ways to switch the balanced mic line but none ae what I would call DIY projects.

 

It would probably be cheaper just getting another processor in fact.
