I hope you are scanning for clear frequencies EVERY time you use the units, especially gigging... and manual channel selection would be a continued gamble, unless you are using some other way to frequency coordinate. The G90 and G10 can frequency scan. Make sure you are all running the same RF mode... see below docs. Unfortunately, Line 6 badly needs to update their tech documents to explain how to support interoperability between their own 2.4GHz products if they expect bands to want to try more than one wireless unit. These docs are very dated. The also need to greatly improve the scanning process as 2.4GHz is a very busy spectrum.

Our band now has G75 with two transmitters (for bass) and both guitarists have G10s. We have had some collision dropouts unless we followed an order of frequency coordination... At soundcheck, setup and scan best frequency on the G70 with G10 off. With G70 freq set, turn on G10 and scan/setup. Once set, if you are turning off before turning back on, make sure you turn the G70 before turning on G10 each time. Autoscan on the G70 and follow this process every time you gig.

On a G75, you can only scan with the receiver/base. There is no way to scan with the TB516G transmitter.

Since these Line 6 systems are all using 2.4 GHz, you should be assessing the RF environment in the location you are trying to use it EVERY time. You must run the channel auto-scan every time to look for clearest open channels. If you are running multiples Line 6 systems, you need to scan for each, leave it active and repeat the process and scan the next until each has the clearest open channel. I don't see this stated in many of the comments from those complaining of drop outs. Just checking if your iPhone or some other wifi device has clear signal is not going to help you and any active wifi device too close to your Relay is going to impact both. With the proliferation of wifi control of mixing systems, there are more devices competing with bandwidth. If you have other wifi devices iPad, iPhone that you use to manage your PA or monitor mix control, if you can, move them to 5.8GHz. You cannot compare to a UHF based system or even Europe vs North Amerian without understanding how crowded the 2.4GHz is where you are trying to use. I use my G75 professionally for 50 plus shows a year with two transmitters, I scan for open channels on both EVERY time, at every location (twice, once for each) 98% of the time I have no issues, but there are some venues where the 2.4 GHz is so crowded near the stage there is just too much interference to use reliably. I don't understand why Line 6 doesn't make it clear that it must be done EVERY time and make the interface even easier to complete this process. I read that the Relay G10 scans for an open channel every time you start it to use. They all should do this. I have been asking that Line6 improve the interface on the G75 since the unit was released to make that the first thing you do every time you turn it on. This is from 2010... and still applies. http://line6.com/support/page/kb/_/live-sound/relay-digital-wireless/24ghz-wireless-faq-r242

Pushing this issue back up. The last firmware update was in January 2017. This user interface needs to be improved and focused towards real life road use.

The steps to complete a Channel Scan on the Relay G75 receiver are more complicated than they should be. In order to not have dropouts in a live show, the channel scanning procedure is something that HAS TO BE DONE at EVERY venue/gig, with more than one TB516G transmitter this is an onerous process. At 50+ shows a year, this is 50+ times to have to quickly do and configure. Especially since unlike the G55, there is no indicator of wireless interference on the receiver display unless you do a channel scan. This is a professional digital wireless system, it should be setup to work that way. Please correct and improve the menus on the next firmware update to make this task logical and easier to complete. The Scan menu selection should be it’s own menu item, not buried and near the top of the list.

Thanks as well for the Best-Tronics Pro Audio Cables recommendation. I ordered a few of these L6G70R-II Right Angle 1/4†to Straight Locking 1/4†Cable but with Neutrik NP2RX-B right angles instead of Switchcraft or the Neutrik gold silent switch they normally offer. They seem to be a great company.

The instructions for channel scanning is incomplete in the Relay G70 & G75 Advanced Guide and in the Relay G70 & G75 User Manual There is no mention of the channel scanning process and how to use properly. I searched through other digital wireless manuals and in the XD-V75 User Manual, on page 14 I found instructions for a similar process. I assume it works the same way. This should be updated in the G75 user manuals to correctly provide instructions, as you know this really critical to an error free experience of using digital wireless systems. Also, the steps to get to the Channel Scan on the G75 are more complicated than they should be. The channel scanning procedure is something that should be done at every venue, with more than one TB516G this is an onerous process. Especially since unlike the G55, there is no indicator of wireless interference on the receiver display unless you do a channel scan. I would like this improved on the menus on the next firmware update to make this task easier to go through.

I replaced my Relay G55 with a Relay G75. The G55 was in a 1/2 rack soft case which worked great. The G75 is an odd sized amp-top design, not sure why it wasn’t also designed as a 1/2 rack, but any protection case ideas? Is Line6 planning on releasing a case for the G75

The TBP12 transmitter body packs are prone to the battery door opening due to their design. This was one of the reasons that drove a redesign on the TB516 G body pack (and is stated in many product reviews as an improvement). That alone should drive your decision. I play upwards of 50 shows a year, and just replaced my G55 with a G75 after getting tired of having intermittent shutdowns on multiple body packs due to the door opening inside my strap pouch. With multiple instruments having to shut down each body pack during a show to switch basses was doable, but I am also looking forward to the ease of scene switching on the G75 and the different output levels.

I use two http://neotechstraps.com/wireless-pouch.html for both my TB516G’s and before that two TBP12’s. They work great.
