Shooting a conference presentation with two cameras - two (sennheisser ew series) wireless setups to each camera:

XL2: SIGN four channel mixer capturing moderator with a lav and table of (four panelists) with a Crown pzm.

GL2: Mixpre two-channel mixer to capture panelists with another pzm, and audience questions (directed to panelists) from a handheld.

I've checked available frequencies chart to tune recievers -

I've never run more than two wireless at the same time. Am I asking for trouble?

Will audience full of cell phones interfere?

Any other advice? (I know, get a sound guy....). Not this time....

What state and city are you in?
Will you be shooting in a hotel or building downtown?
Maybe the lav on the moderator could be wired?

I'm in San Francisco - SHooting in a building downtown on a Tuesday night - Room of 40-50 people - Don't think I can hard wire moderator who will be moving, stand up....

Absolutely. One of the major disadvantages of wireless at conferences are the RF hits you take from cell phones. I get them even with Lectro and Zaxcom units. Do your best to keep your equipment away from cell phones, but just be prepared for some interference.

As far as using more than two wireless, I don't think you're really asking for any more trouble using four than you are with two. Just make sure you space your channels out correctly. If you don't you'll end up with intermoddulation problems. A general rule of thumb is to use 100 kHz spacing. I don't use the G2 systems, so I don't know what is available, but just be aware of this when using more than a couple of wireless units.
