Rated 4 out of 5 by from Microphone for dummies- sets up in seconds.I received this mic one day prior to a Wedding I was Djing. I put batteries in in, plugged it in and everything worked. I used it outside at the ceremony, and inside for the reception. No dropouts, no static, and I never even changed channels. Outstanding! Had two vocalists sing live also, and sound was excellent.

I don't know much about wireless mics, but wanted to know w/the 2000 series can you add another mic to the system? Is it as simple as adding the 2nd

mic to the same frequency. What mic (model#) can I use?What about a wireless head piece (model#) that can be used with the 2000 series. By the way, this would be used at a school in it's theater/auditorium.
Asked by: kidflash
No, this type of system will not accommodate an additional microphone that will operate simultaneously with the included microphone. You could purchase a headset mic and use one or the other, one at a time, but not both together. The only systems that will allow multiple microphones on the same receiver are the models that include multiple microphones. I've referenced a couple such products below for your convenience.
