Wireless Groups and Channels Explained | Shure

When setting up multiple wireless microphones, it's imperative that each one is on a clean frequency. This will prevent interference and audio dropouts. Join Yuri from Shure as he explains how using Groups and Channels can solve this problem and why it's so important to coordinate your frequencies, especially when operating systems that are not in the same group.

excellent explanation

Hi Yuri, Quick question, I have a Shure ULXP4 and it wouldn't show Mic signal on the LED meter. It's locked into identical Group/Channel on both Transmitter and Receiver but when I speak into the mic, no signal. Tried different groups and channels but to no avail. Please help!

HI Yuri. If I already have an AKG Receiver (fixed 864.375mhz - ism 2) is there a way to set Group / Channel on the BLX-1 863-865mhz Beltpack Transmitter to match that ? Then I can buy the Shure bodypack. Thanks.

So my question is, more and more I see different brands of IEM and wireless mic pop up at shows.... Shure PSM, Sennheiser, etc etc.
How would one handle that, turning them all off and scanning and sync'ing one at a time? Only channel, because group is irrelevant?

Hey there. If working with multiple channels of wireless (whether only ours or multiple manufacturers) I recommend using our free wireless workbench software to find available frequencies for each device instead of using groups and channels. Unfortunately groups and channels don't have any consistency across different manufacturers or even different Shure wireless product lines. More info here: www.shure.com/en-US/products/software/wwb

@@shurecreators so if I have a series of PSM300's and some Sennheiser G4 out there, I can put them all in the software without need to network ,right?

[@shurecreators]

@@lookmanostrings Yes! Though G4 is not currently in the Wireless Workbench System, so for that you can create a "Generic Device" in the software with the frequency range of the G4 units you have and then it will find open frequencies for them.
Also if you only have those items, you won't have anything networked to do a frequency scan, but you can download a scan from our scan library at whatever location you're at.
That being said, If you'd rather use groups and channels instead since that will ensure your devices do a scan of the room, you would start with one transmitter/receiver - find a group/channel and then sync the transmitter and leave the transmitter on and do the same process with the others (each time leaving the transmitters on after you've found a channel for them). That way for every scan you're doing, the devices will find the transmitters that are already on, avoid them and find a clean channel.
