always wanted a reason to use this bc the iem way works 99% of cases but http://whirlwindusa.com/catalog/digital-audio-networking/e-beam-laser/ebeam

freaking laser beams

I think at one time they offered that with an analog audio IO.
Says it not affected by rain but I still wonder how hard of rain it would actually work in or snow for that matter.

Anyone actually ever used one?

Haven't used it, have heard they have to be exactly aligned - a laser doesn't have much (any) margin for error.

Rain shouldn't be much problem.  If you do the math of how much water is actually between Tx and Rx at any given time - it's shockingly low. 

Large, lazy snow flakes I assume could be more of an issue.

I was thinking that to as in needing a really solid support at each end.
As I was glancing at the specs they mentioned the beam was one meter in diameter at 500 feet.
(I found it kind of odd they used two different measurement standards in the same sentence)

These should do the trick with correct antenna setup.

Getting laser systems up and running takes a while, wouldn't want to have to do it under pressure of a gig. I've only been around it being set up for fairly long distances (10+km) and the beam alignment took a couple days of trial and error to get everything reliable.

WHAt kind of distance can i expect with that LetroSonics system?

Properly set up?  Over your 500 ft needs.

Shoot an email to Karl Winkler at Lectro.

generally the same as most other iem systems of the same tx power rating ... lectrosonics are rock solid and built quite well but just not the budget route by any means but very well made and great audio quality.

I’ve done a downhill gravity car race using PSM1000 with helical antenna at the finish line and beltpacks as recievers further uphill. Worked well, it was easily more than 500ft to the start line.

You can easily get the 500ft you need with a directional antenna setup. You way even be able to get 500ft with the included whip antennas, depending on the RF environment you are working in. The D4 system is 200mW which is at least double the power of any IEM on the market. Also TX sends two channels over the same carrier, so lower IMD than using (EDIT) a pair of IFB rigs.

EDIT: The D4 system operates up in the 900MHz band, which is pretty open, right now.

If you only need a single channel of audio, you can shoot it with a Lectrosonics IFB unit. Those put out 250mW.

If you want to email me I can see about getting a demo unit over.

. Also TX sends two channels over the same carrier, so lower IMD than using stereo IEM rigs.

 Excuse me if I'm misunderstanding your meaning, but the analog stereo iem units I'm familiar with broadcast over one carrier. Stereo operation does not add another carrier frequency.
