  1. As long as you keep your paddles well away from the router antennae, you should be OK. Don't forget that sometimes where you point the null of the P180 paddles is more important than where you aim the front of them. Always check the status of the receiver LEDs with all transmitters switched off but the WiFi stuff switched on. That'll show you any potential issues.
  2. Fair enough. I figured if the PSU was borderline, the slight increase in loading when it was doing more work upon receiving a valid signal might tip it over the edge which would then cause unexpected behaviour with the receiver. As with all troubleshooting, divide and conquer is the way to go - substitute each component that you can and see if the problem stays or goes away. It's either a fault in the receiver itself or in the PSU. If you can rule out one of those, you'll be a step nearer to identifying the fault.
  3. It doesn't sound like a common fault. Mains power supplies are often the most failure-prone part of equipment so I'd be inclined to start by looking there. Do you have access to another PSU that you could try with the receiver? It's 9v at 500mA. If your current one is struggling, it might explain parts of the receiver shutting down.
  4. Sounds like you might need to check whether you're in RF1 or RF2 mode. If you had more than one mic switched on and were mixing modes, you'd get exactly these symptoms. In virtually all cases, you'll want (everything) to be in RF1 mode. Do you have any other equipment close to the receiver that transmits anything on any frequency? Bluetooth music steaming, wireless lighting control, mobile phone etc? If so, move them several feet away. There are lots of RF issues to be aware of when using wireless mics - they're never plug & play, no matter how cheap or expensive they are. I've seen several people on here adamant that their equipment was faulty only to discover it was something like them leaving a spare transmitter sat on top of the receiver! Keep everything that transmits well away from your receiver antennae.
  5. These Line6 receivers won't be damaged by phantom power but some other receivers can be. It doesn't provide any benefit so it's good practice to not apply phantom unless it's actually needed e.g. for condenser mics and active DI boxes.
  6. What happens if you connect a wired mic to the Korg input? It might have been a typo, but you'll need an XLR to TRS not TS cable to connect (anything) to the Korg. I suspect part of the problem may be that you're using a lavalier mic - because these are used so far away from the mouth, you need a lot more gain than you do with any other type of mic. The input on the Korg will likely be expecting someone singing at close proximity in to a handheld type mic which will produce a vastly higher signal level.
  7. The outputs of the receiver are designed to operate at exactly the same level as a microphone so you can treat them just as if there were a direct connection to a microphone. In a conventional live setting, that means connecting the XLR output to the mic preamp input of a mixing console. (This is all explained in the manual.) Don't worry about only seeing one light on the meter - that's normal. These mics have a huge amount of headroom so it's almost impossible to overload them. You'd have to be really screaming to light all of the meter LEDs! There's no level adjustment in the transmitters because they have such a large dynamic range, that they don't need it. Same as how a wired mic doesn't have a built-in level adjustment. Your best option with the Kronos would be to use a balanced XLRF to 1/4" jack cable. Set the Kronos switch to mic level. The preamps in there won't be particularly high quality but you shouldn't hear any difference between connecting a wired mic to those inputs and using the Line6 mic. Don't worry about phantom power - you don't need it with radio mic receivers (and indeed some will be damaged if you connect phantom to them). I wouldn't recommend using the jack output from the V75 receiver. It's the same level (I believe) as the XLR but unbalanced. If for any reason you do ever use it, you have to use a two pole jack (TS), not three pole (TRS), as the ring is used for digital communications with other Line6 products and will introduce noise if it's connected to an audio input.
  8. Having a cluster of antennae close together at the back of the rack is a bad idea, and not just because it looks messy. Each antenna, although fitted to a receiver, also functions as a transmitter, albeit at a very low power level. (It's the nature of receiver electronics that a small amount of signal is sent back to the antenna.) This means that each receiver is surrounded by a cluster of additional transmitters which is bad news for RF performance. Also, as frequently demonstrated on this forum, antennae being located at the back of the receivers is rarely the optimum position for them as good line of sign is generally limited and proximity to other equipment is likely. Getting them up in the air and away from other equipment is always beneficial, even if just using the included antennae rather than the P180s.
  9. Any system that doesn't use the 2.4GHz band will work here. Sennheiser (Evolution G3 / G4) / Shure (UHF-R) are the usual suspects; other brands are available. Your local hire company will be able to help - depending on which country you're in, you may need to use a licensed band as you may not fit 10 systems in to free spectrum.
  10. The output is almost certainly current limited as the mic capsules only need a couple of milliamps.
  11. Strangely that's a feature you'll only generally find on very low end and very high end systems; rarely in the middle ground. Yes, pretty easy to make so one can only assume it's a marketing decision.
  12. Have you checked with the V75 bodypack in RF1 mode? They usually default to RF2 whereas the V30 will, I think, only work in RF1.
  13. Line 6 doesn't use the the same wifi tech - it doesn't actually use wifi at all. It operates in the same 2.4G band as wifi but that's where the similarity ends. There's no relationship between Line6 channel numbers and wifi channel numbers - Line6 uses up to four fixed frequencies per channel - totally different to wifi. You're right that wifi scanners won't see Line6 traffic - because it's not wifi - there are no SSIDs or any other identifiers that wifi equipment is able to detect.
  14. That may be your undoing here. Forget everything you know about WiFi - although these mics operate in the same frequency band as WiFi devices, that's where the similarity ends. They're not WiFi devices, they don't use the same channels / frequencies and they won't appear in WiFi scans. To try to address your other points in order... Dropouts are usually caused by other devices emitting RF near to the receiving antennae. Laptop / phone / Bluetooth device / spare transmitter / microwave / DMX transmitter or a whole host of other devices. Keep anything that produces RF (irrespective of what frequency) several feet away from the antennae. It doesn't really matter which channel you use. The RF2 frequency allocations are designed to fit around certain WiFi channels so that they can coexist. Details of which L6 channels work with which WiFi channels are in the manual. If you don't really need WiFi interoperability, use RF1 - it's far more robust but will slow down nearby WiFi. The P180 paddles can be useful if there are potential sources of interference nearby as you can point their nulls towards it to minimise pickup. I'd suggest they're almost always more useful than the P360 paddles which you'd probably only use if surrounded by mics. The UHF band extends from 300MHz to 3GHz so yes, these are UHF devices. I don't think cables are supplied with the paddles. Buy the proper Line6 cables - yes they're expensive. RG59 or similar won't work well at all. Position the antennae so they have clear line of sight to the transmitter which usually means getting them up above head height. One or two bodies in the way won't be a problem but several rows of audience members might be if they're too low. There is a small amount of gain available in the paddles but that's only there to overcome losses in the cables. RF signals at 2.4G can be amplified just the same as any other RF signal. Assuming you're talking of the handheld mic, the heads are interchangeable so you could fit a super cardioid head.
  15. IEM transmitters aren't likely to be adversely affected by the proximity of other receivers. I would check that you're using compatible and legal frequencies.
  16. The receivers automatically detect the mode that the transmitters are using so you're correct - no changes needed there. Please tell me your IEM transmitters aren't as physically close to the L6 receivers as they appear on your diagram? Even if they're on a different frequency band, you still need several feet of separation between any transmitters (antennae) and your mic receivers (antennae) in order to avoid swamping their inputs.
  17. First of all, there is no relationship whatsoever between WiFi channel numbers and Line6 channel numbers. There's no point trying to avoid WiFi by choosing corresponding channel numbers. Secondly, you're currently using the mics in RF2 mode - this is a less robust mode that is more prone to interference from WiFi. I'd suggest changing them to RF1 mode which is significantly more reliable. If you still have problems after that, you'll need to look at the positioning of the receivers/antennae in relation to the stage and the positioning of the IEM transmitters/antennae in relation to the L6 receivers. Proper RF signal distribution / combiners are also important - a cluster of antennae near each other is a recipe for trouble. Finally - I'd suggest reading the manual cover to cover - all of this and a huge amount more is covered in detail in there. RF systems are never plug & play - you need a decent understanding of them to get the best out of them.
  18. All V75 systems come bundled with the necessary rack mount hardware. I suspect it's not (easily) available separately as you wouldn't normally need to buy it again. The "feet" on the rear of the V55 receivers look like they're in the same positions as the V75 but the mounting holes elsewhere are different. The V55 rackmount might be compatible, but certainly no guarantees there.
  19. Correct - it's only the transmitters that need to be changed. I don't know what voodoo the receivers employ but presumably they do listen with a sufficiently open ear to know which frequencies to monitor regardless of which mode is being transmitted. (Perhaps there's one common frequency between the two modes - I'll have to dig out the list of frequencies they use.) More mics shouldn't automatically mean more issues. You can theoretically use 12 together (14 in RF1) so I wouldn't expect you to experience additional problems just from adding another two. Usual RF good practice still applies e.g. being aware of near/far effects and not leaving one mic right next to the receivers whilst the others are at the far side of the stage. It does sound like you're playing in some tricky venues (from an RF perspective). I'm fortunate in that I have some control over what other kit is in use in the venues I use so I can minimise any issues before they arise. Although the L6 kit is great in a sympathetic environment, it may not always be the ideal choice where you have to fit in with whatever else is already in the venue. An enterprise grade access point right above the middle of the stage will always be tricky to deal with!
  20. You did change both mics to RF1 didn't you? The two modes are completely incompatible so you have to run them all in the same mode. There's no relationship between the channel numbers in one mode and the numbers in the other mode. Interesting. Although the L6 channel scan displays 14 channels, they aren't in any way related to the 14 WiFi channels. Sadly the scan is also only useful in RF2 and won't show anything meaningful about the 12 RF1 channels as they use a completely different set of frequencies. (Each RF1 channel uses four different frequencies spread throughout the 2.4G band. Each RF2 channel uses two frequencies.) WiFi is a tricky beast - so many devices are frequency agile and will jump around and/or only transmit intermittently, so unless a scan averages out data over a long period of time, it won't necessarily show useful data. I never actually bother with scans when using the L6 mics - as I routinely use 10+ of them, it's impossible to avoid any existing RF traffic so it comes down to physical placement of equipment rather than channel avoidance.
  21. Maybe something related to their power supplies? Have you tried swapping out their power adapters for known good ones? And swapping those PSUs to known good receivers? Failing that, probably a repair job.
  22. 1. I would always recommend RF1 over RF2. It's more robust; you won't notice the difference in a quiet RF environment, but once you have an audience full of mobile phones in, the extra security it offers will be very useful. It uses four frequencies to transmit duplicated data whereas RF2 only uses two so it's a lot more resilient to interference. 1.5. It's unlikely that your UHF troubles are directly related. You're not leaving a L6 transmitter right next to your UHF receivers / antennae are you? Or clustering all of your receiving antennae very close to each other? 2. There's no gain adjustment but the headroom is enormous. I've never managed to make one clip. Some mics are more sensitive than others so it's technically possible that a real screamer eating the mic might cause a problem but I doubt it. The receiver outputs are set to roughly the same level as an equivalent wired mic output so as long as you treat the mic preamp gain the same as you would with any other mic, you should be fine.
  23. Getting the receiver antennae up high is part & parcel of making sure that's not an issue. I've seen signal strength vary a bit if an actor is tightly surrounded by others but nothing show stopping. Preventing the TX antenna contacting bare skin is, I believe, a good idea although costume practicalities can get in the way of that. The L6 TX antenna is just a bare wire inside that dome so it's perhaps less of an issue than those packs that utilise an external flexible wire antenna.
  24. Bear in mind that you'll have hundreds of mobile phones between stage and receivers, all transmitting wifi and bluetooth in the same band as your L6 mics. I would put the recievers side of stage if you possibly can. They'll almost certainly work fine out front in an empty house but once the audience is in, it may be a different story and there's no way of testing them in those conditions without an audience. The lack of remote monitoring is my only significant frustration with these mics; I'm not usually working with a sound no. 2 who can keep an eye on the receivers.
