Within the range of Shure ULXD wireless microphone systems, there are different types with different frequency-bands in which they are active.
But, some frequency bands have the same range.

For example:
G50 can be used from 470 to 534 MHz
G51 can be used from 470 to 534 MHz
G52 can be used from 470 to 534 MHz

What is the difference between these types?
Are these different types compatible with each other? Does a transmitter G50 works together with a receiver G51 (and the other way around)?

Here is a current listing of Shure wireless frequency bands for all products in the U.S., http://www.shure.com/files/pro_wireless_spectrum_chart.pdf
I don't see either G51 or G52 listed, only G50.
I am not sure where you are located.

When I do a google search for the other bands I get results that indicate that G51 is specific to Europe and that G52 is specific to Asia.
This is also shown in the ULX-D manual for, frequencies for European countries are shown as x51 bands (G51, H51, K51, P51, R51).  I do not see the same listing for the two x52 ranges listed but these are both in more limited RF power output (1/10 mw) and a Google search did get me Asia specific application info for those bands.

I can't answer about compatibility between units but I would be quite certain that since these units are certified by country for RF compliance it may be problematic to use them in countries where they are not certified.

Lee's response is essentially right on. The various G5_ ranges are jurisdiction specific and have to do with respective certifications as it relates to the spectral mask (occupied channel bandwidth and out of band emissions).

Hello,


Thank you both for your answers!

I found this chart on the web:
http://cdn.shure.com/frequency_chart/upload/666/wireless_compatibility_ulxd.pdf

As you can see, the frequency range of G50, is the same as the range of G51 and is the same as G52. Their ranges are all from 470 to 534MHz.
I only see a difference in the compatible useable frequencies. (group 1, group 2, and so on). Moreover the frequencies of the first 3 groups are the same. The higher numbered groups differ.
If I transmit for example with a G51 transmitter on a certain frequency, can this transmission be received by a G50 receiver set on the same frequency?
If this is possible, I don't see where problems (disturbances or transmissions on illegal sidebands) can appear.
I believe sidebands (on location specific allowed or not allowed frecuencies), do only appear when multiple systems are used together, no?


Regards,
Peter

Henry can better respond to the technical differences, if any, in companding or other processes that may create incompatibility issues between tc and re for different markets. 

The Asia specific units are limited to 10mw max output. 

None of the units are certified for radio operation in countries other than those for which they are specified.  Even if they will work I would not want to accept the fines for operating unlicensed radio equipment in any of the various countries in question.

The difference in wireless bands among same band range (G50 and G51 for example, but NOT G vs. J bands)  are software based, rather than hardware based!

That means that G51 can become G50 for example with a software change, but G band CANNOT become a J band.

To do the change follow this steps:

1. Have your transmitter ready
2. As soon as you turn it ON press EXIT + ENTER fast
3. A password screen will come up asking for a password
4. Use the UP/DOWN arrow keys to select "D" as your password and hit ENTER
5. Under "Band" menu, you will be able to select between G50/ G51
6. Done!

Good luck!

Out of curiosity does this change the output power?

Hi Justin,

I would presume that you're still going to be limited based on the options presented in the menu options.

However, also please note that "ATDAV" is posting without using their Real, Full Name as their Display Name. It's appropriate to respect the Forum Rules by *not* engaging with users who are ignoring those guidelines, other than to admonish them to abide by the rules!

I signed with my name and edited the name on the profile.

You will be able to change the output between 10-20mW

It seems like you have been reading this thread, but failed to note that you must use your REAL NAME per the forum rules.
You will get no response until you do.
