Title: Sennheiser Wireless Transmitters and Receivers

Wonder how something like this would work for wireless board feeds and remote microphone placement?  I have found that boards are now being placed all over the place since they can be controlled remotely with an iPad or phone.  Makes gettting a board feed a bit more difficult.  In one venue here, the board is actually behind the stage.  If the quality of the sound is up to par, a pair of these systems might be a reasonable way to get a board feednwithout having to run cables all over the venue. Same facility if you want to use remote mics without running cables.   Compared to Electrosonics gear (industry standard), this stuff is quite reasonable.

Wow, this is really interesting. I really want to test this out... would be awesome to be able to cut a few cords- especially with regards to clamping somewhere up above the crowd or something.

e: Lol, I'm dumb- immediately after I wrote this I realized that you'd still need to power the clamped mics somehow. Still, it would be nice to not be tethered to the board. Thanks for posting, going to consider picking one up.

This is nteresting in terms of a soundboard feed. I’d imagine sound engineers would be more willing to just plug one of these in and forget about it rather than deal with cables and it’s a lot less aggravation in terms of other venue staff objecting etc...

Yeah, need to look into freestanding phantom power modules.  Happily, I have a pair of battery powered Schoeps that I could just plug these units into.  Would be nice to be able to use my other condensers though.  Dynamic mics would work of course.  Something like a Beyer M201 might be decent if it was placed well.

Mackie makes a battery powered phantom supply box that isn’t too expensive.  You would need to figure out how to clamp everything since you would then have your mic, the wireless unit and the box to hang.

Or you could pair them up with something like the K6s in the Yard Sale - those are battery powered.

And then there is the Denecke PS2 which would power two mics if you had them mounted together.  Again, pretty reasonably priced compared to some other options.

Wireless miking has inherent reliability problems that make it essentially a last resort for professionals. And modern wireless mikes contain wideband companders (noise reduction circuits based on compression before sending, and re-expansion in the receiver) whose dynamic behavior is optimized for its primary application, which is speech transmission.

I owned a professional Sennheiser wireless setup for a number of years, and used it with a lavalier mike for documentary recordings, where the music was mainly being picked up through conventional, "wired" (as eBay calls it) microphones. But I wouldn't assume that it was particularly suitable for wide-dynamic-range music, except (again) as a last resort. I would rather use a locally attached recorder such as a Tascam DR-10X, and sync its results up later.

If people are seriously interested in trying the wireless approach, I would urge them to borrow or rent the equipment for experimentation and critical listening first, rather than buying it on faith. It probably won't take many trials before the problems show themselves, and then people can weigh the pros and cons more fairly.
