Sennheiser Evolution G2 100 Frequency Range Question at DVinfo.net

Josh Laronge · October 20th, 2007, 10:09 AM

I have a Sennheiser Evolution G2 100 kit in frequency range C. I want to get another one of these systems. Should I get the new one in frequency range C or in a different range? Are there any pros/cons of owning the same or different ranges?

These are used for event work. Thanks for sharing you knowledge.

Dear Josh,

If you get another set in the same range, then you will have some options that you would not have if you purchased a different range.

If one receiver goes out, then you can use the other receiver. This does not really have any practical advantages, only it would be helpful in determining if the problem was in the transmitter or receiver. The same would apply if a transmitter goes out.

You could use one transmitter, transmitting to two separate receivers.

However, if you choose another range, and you could not find a clear channel in one range, the other range may be usable.

Be sure to go to Sennheiser's website and check out which frequencies and ranges are available in your areas.

In 2009, our normal TV channels (analog) are scheduled to go off the air, as specified by the FCC. Then, the FCC is expected to sell off this frequency spectrum. When this happens, it may be more difficult to find an open frequency in a particular range.

So, I would first check Sennheiser's website. If there is another range, in your area, or the areas that you expect to use the equipment, has many open channels, I would get that range.

If Range C is currently wide open in your areas, then getting another Range C set is probably ok also.

In my opinion, there is no clear answer, as it is hard to predict the future due to the expected changes. Which channels will be open in any given area can not be predicted.

Thanks Dan.
You confirmed what I had thought but wasn't sure about. I had checked Sennheiser's site for the frequency ranges (bravo to them for having this chart) and C is fine for where I do most of my work. I'm going to go with getting another C because of the extra options it affords me.

To be honest with you with Block C of Sennheiser being 740 - 772 MHz, I'd be a bit concerned. This block falls smack in the middle of the range the FCC wants to reuse/sell. Just recently AT&T announced it was purchasing 700 MHz (how much of 700 MHz I never could quite figure out from the press releases), but none the less. I think Block C of Sennheiser and pretty much anything above block 27 for other wireless companies will be a crap shoot. Obviously things aren't fleshed out and there remains a lot of doubt as to how much this will affect the wireless community, it is none-the-less important to consider when buying gear. It might simply mean you'll have a tougher time finding free open frequencies, or it could mean that you might have to have it changed to block A, or B. I don't want to scare you off from buying block C, but certainly consider these things when buying new wireless.

I have one set of C now and haven't experienced interference yet. In my area the chart shows stations spread equally across all 3 ranges so I can't really go by the chart to pick.

I wasn't aware this was possible. Is this something Sennheier does? Do you have any information about it? It seems like a great idea if the frequency range becomes too crowded in the future.

I have no clue what Sennheiser plans to do. Zaxcom and Lectro have said they will change out boards (for a fee) if the proposal causes issues. As I said, right now nobody really knows what is going to happen. Sennheiser G2 units are inexpensive enough that it's not like spending the $2500 or $4000 US that Lectro and Zaxcom units cost. But, still if I was planning on buying new gear I still would consider that things might change in a few years.

Hi all,

FYI - don't look for Sennheiser to help with "swapo-chango" frequency changes for our existing units. Here's the latest on their official position.

Good luck, Michael

Hi Michael,

Unfortunately, we no longer can re-frequency Evolution Wireless systems. I suggest going to our website to find a local dealer where you can purchase systems in the frequency you are looking for: http://www.sennheiserusa.com/dealerLocator/

Hey, Thanks for this Michael.

With the complete set selling for $500 it's really not a huge deal breaker that they won't re-frequency them. I'd imagine that it might be almost $500 to re-frequency a $4000 set anyway. Also, just because the FCC plans to resell the frequency range doesn't automatically mean these units will be no good (and no one will really know for sure for another 14 months). While there's no dispute (except maybe by Sennheiser) that these are not the best wireless system available, they do a great job for the price.

Righto - so even if the available frequency channels drops from 90% to 50% in a given area, that shouldn't really be much of a problem (famous last words...)

Bob Grant · October 24th, 2007, 10:50 PM

I think you'll find if you spend a bit more money on the 500 series you get the choice of all the banks in the one unit.

Dan Keaton · October 25th, 2007, 09:30 AM

Der Bob,

Sorry, but I do not think that is correct, if I understand that you meant that all of the frequency ranges could be purchased in one Sennheiser 500 unit.

Even with the Sennheiser Wireless 500 series, you have to select a range.

In the United States, the Ranges are, in Sennheiser's terms, A, B & C.

Steven Davis · October 25th, 2007, 09:36 AM

Josh, read my thread http://dvinfo.net/conf/showthread.php?t=99304 It may answer a lot of questions you have about this system. I learned the hardway that online frequency checks are not perfect.
