Has the transmission mode changed as part of the firmware updating process? If it's changed from RF1 to RF2, that might account for it. Similarly, if one mic is on RF1 and the other is RF2, that will definitely cause problems. Which firmware versions did you update from and to? I've not noticed (although I've not looked for) a newer version than the one that my V75s came installed with.

Shouldn't be a problem - universal power supplies are designed to be able to be used anywhere in the world.

3rd solution (not perfect but might be useful): Antenna A -> RX1 -> RX2 -> RX3 -> RX4 -> RX5 -> RX6 Antenna B -> RX6 -> RX5 -> RX4 -> RX3 -> RX2 -> RX1 You obviously lose a degree of diversity by chaining the receivers in that way but if your signal strength is good, you might get away with it. Edit to add: Either the seller was misinformed or they were lying.

Yep - the Line6 XD-AD8. Which also happens to function as an eight way antenna distro too ;)

Could you fit a less sensitive capsule? If there's something suitable out there, that would seem to be the simplest option.

No - don't turn on the phantom power. That's only used if you're connecting microphones that require it - usually condenser mics. It's not needed if you connect other equipment like a radio mic receiver; in some cases it can cause damage if the other equipment isn't designed to handle it.

Do you mean you tried the Rode mic connected to your Line6 transmitter or connected directly to your Tascam interface? Some basic troubleshooting required here: What happens if you connect a normal microphone (SM58 or whatever) to your Tascam - are the levels OK there? What happens if you connect your Line6 receiver to a different mixer or interface - how are the levels? It's only by going through a process of elimination that you'll be able to determine exactly where the problem lies.

You are plugging in to a microphone input on your interface aren't you? The output on the receiver is set up so that it's roughly the same level as you would get out of a normal wired microphone. Don't worry too much about the level meters - you have to be quite loud for them to light up much.

Trying to use that many 2.4G mics and WiFi devices that all operate in the same band is asking for trouble - it's very unlikely that they'll all happily work together. Would I be right in thinking that your V70 receivers and the X-Air are in close proximity to each other? That's also a really bad idea. If your tablets will work on 5GHz, that would be your best solution although it does mean another bit of hardware to carry and set up. You'll still want a bit of physical separation between the V70 receivers and any WiFi devices though.

If memory serves, the V75s auto-terminate, so you shouldn't put a terminator on the outputs if it's a V75 at the end of the line.

Do you have a phone in your pocket when it's doing this? Anything that operates on the wifi band in very close proximity to the receivers is likely to be problematic.

As a suggestion for a possible future firmware update, how about adding a setting for the type of battery used? I've seen that in digital cameras that use AA batteries so it's not uncommon. It would presumably simply tweak the relationship between voltages and time remaining to give a slightly more accurate picture than the standard alkaline setting. This assumes that such things are done in software rather than hardware of course...

Have you upgraded the firmware in the receiver? My recollection is that until you do so, the receiver won't work with RF2; you'd need to change the transmitter to RF1 mode. Try switching the TX to RF1 to test this out. If it still doesn't work, I'm about out of ideas.

If your G30 TX is on the table alongside your V35 receiver, I'd say that's probably where your problem is. Putting a transmitter (even on a different channel) in close proximity to a receiver is asking for trouble. With analogue systems I'd call it receiver de-sense - the receiver is swamped by the nearby transmitter and can't pick up the more distant one.

Just to clarify a little: You were using the G30 beltpack to send a signal from your mixer back to stage? Presumably the receiver for the comedian's mic was out front next to the mixer? Where exactly was it in relation to the G30 transmitter?

I'm not sure that's entirely true. I've seen a number of people posting that they've had good results on theatre shows (beltpacks) with 14 sets. I've only used six at a time thus far (always RF1; along with 12 G3 transmitters) and have never experienced this distortion issue. I'm still very interested to get to the bottom of it though.

The receiver automatically detects which mode you're transmitting so you don't need to change any settings there. RF2 mode was implemented to allow users to work around the presence of wifi traffic without causing undue interference. RF1 is much more robust but tramples all over wifi. As long as you don't need to avoid any wifi channels, RF1 is a better bet. (Having said that, I don't think you can avoid any wifi channels whilst using as many as 12 channels in RF2 mode anyway).

For the sake of completeness, the Line 6 UK web shop is here.

Yes. I bought a handheld TX on its own from GAK last month; they also do beltpacks. I'm sure Line6 have a web shop too that you can order individual parts from. I've seen them available from other dealers too so it's not uncommon.

An intriguing problem! When you switched that one pack to RF1, were the others still transmitting on RF2? A bit of an unfair test if so as they'll never work correctly like that. Either way, I look forward to hearing the resolution of this one.

I hope your lawyers are commenting to theirs... ;)

There does appear to be more than a passing resemblance...

If you happen to have a multimeter in your toolbox, might be worth metering the PSU output should things go awry again - that would at least start narrowing down the cause of the problem.

There's a Line6 video explaining the process here: https://www.youtube.com/watch?v=up41nyqUnlE
