2nd wireless Sennheiser

I want to get a second wireless senn unit as well, I don't think that should be a problem, would it?
 
We have two Sennheiser's one range "A" and the second is range "B". They also make other frequency ranges "C" and so on. If you want to make sure you wont have interference when using both transmitters use two different frequency ranges. That's why we have the frequency ranges.
 
We recently did a wedding in a church where we had to put both transmitters on the groom.
One "A" range set at 518.150 was transmitted to our on cam receiver. The other which was a "B" range, at 630 to 662 MHz was used to transmit through our receiver which was connected to the church's sound board for amplification through the churches speaker system (so they could hear the bride and groom recite their vows). The church had a "C" range and a lav on the preacher to transmit to their receiver which was connected to their sound board. No interference problems at all.
 
If you are going to buy a wireless Sennheiser, I would highly recommend the Evolution G2 100 series that includes an SKP 100 G2 plug-on transmitter for a handheld mic. We use them for interviews and our clients love it. They think they are going to be on the news at 10:00 or "Twenty/Twenty"! They transmit for about 400 ft. and you can hear the rustle of the bride's dress as she goes up to the altar even though the mic is on the groom.
 
You can run several transmitters of the same range set on different frequencies simultaneously... the reason that the frequencies are set in channels is because those individual frequencies are already predetermined to NOT cause intermodulation distortion... i.e. no interference. When you tune your Sennheiser MANUALLY like a radio dial you are taking a chance... tuning it by changing preset channels is totally safe.
 
Are you quite sure that if you locate the transmitters next to each other and they are in the same range but on different frequencies that the RF's wont collide? How many MHz do you have to be apart to avoid this when your transmitters are right on top of each other?
