Do you get the noise with anything else as the source? Try playing back some recorded music.

Make certain you plug the USB cable in BEFORE you plug in the power supply.

The signal is refreshed/rebuilt each time you hop so the length of the cable is the gating factor not the number of speakers (inside the limits of 9 tops and 9subs)

Yes ... You want to set your projects in your DAW to 48k sample rate. That will match the way they are recorded on the M20d

Not every "reader" of wav files uses the same amount of headroom as a basis for "level". So wav files may appear higher or lower in level depending on what is reading them. Not really a problem. Just load the files into your DAW and then "normalize" them to your DAW.

It's all about how the cable "loads" the digital sending device. In the case of L6 link the ideal load is about 110 ohms. Typical non-AES cables are typically about 40-50 ohm (transmission line impedance ... not resistance). So when you begin to bog down the sending device you begin to get unstable waveforms. Now the system can still read them for a while but as you add distance to that cable then they continue to get worse to the point that they can no longer be read in sufficient numbers for the receiving end to make sense of it. This is not so much about digital or analog but it is more specifically about L6 link and AES/EBU links. Also, generally there is no issue sending analog down AES cables.

Likely not firmware. If it were firmware it would pop up on every unit. Probably a hardware issue that should be seen by the service department. As far as scenes and setups. ... Scenes should load very quickly but setups take a few seconds.

Sorry ... I missed this. You have nothing to worry about for a fair number of years. X2 transmits on an ISM band (as does the XDV's at 2.4G) and the FCC doesn't make the rules for ISM bands

It's not that difficult. If someone wants to send you their recording they just need to save their setup and send it too. You just load them into your mixer and then load the recording files onto an SD card and they will play back.

OK. Try building a new setup. Does it still happen?

I think you'll find your "lagging" issues are related to using a dongle USB Wi-Fi stick. Switching over to a regular router will improve it.

That would be normal if not every speaker was being recognized because of a poor connection. Remember the system sets itself up based on the total number of speakers it sees. So if it started out with say 8 speakers but then it only saw 7 in the chain it would reconfigure itself for a seven speaker setup. Probably the monitor mixes would shift to different speakers.

What firmware is in your L3/S's? You can read it in the update page in the mixer. V1.05 is the most current version and is more stable when using multiple speakers. Every time I have seen speakers re- enumerate it has been because a cable was kicked and there was momentary loss of signal in the L6 line. You may have bad cables or bad jacks on the boxes themselves so you need to carefully check through them.

Are you seeing anything else lit up in the I/O panel (top of the setup page) besides the two sources I see on your screen?

Crackling can occur if you are connected via L6 link and the cables are not AES spec. Usually it's not a problem to use regular mic cables with runs 10'feet and under. So what I would check first is the firmware version of your speakers. Hold the feedback button in while you power up and it will read (quickly) in the LCD window. There was a firmware rev (1.05) that did eliminate clicking that could sometimes happen if more than 3 speakers were hooked together. If you have an older version then you should flash the speakers with the newer version through your M20d. If you have the newest firmware but are hearing clicks then I would check whichever speaker you are hearing the clicks in with your 6' mic cable and with your Bestronics cables and see if if clicks with both. It's possible that the cables do not meet AES specs but you'll need to prove that out. One other thing to check ... does the number in the LCD window flash when you hear a click. If that is the case then I suspect a jack or plug is not making complete contact. If you have the newest firmware and it clicks with any and all cables then it probably needs to get looked at by the service dept

OK. I can't see the PAD settings. If they are the same on both channels then it would appear you may have a hardware issue that requires service.

Sound cards from computers are notorious for creating noise. This is often power related from the computer side. It appears that you are running an unbalanced cable into the L3 so you'll get no benefit from the noise reduction offered by a balanced connection. Does the noise go away if you unplug from the sound card? The fix will most likely be to insert a balancing transformer between the source and the L3.

Are you still running in lo-power mode. If you are not getting signal then you must move up to high power. Are you running in RF1 mode?

Nothing much more you can check. You'll need to send it in and have our service department check it out.

Unfortunately no.

It would seem that the receiver would be suspect but we should rule out a couple of other things first. Try the shorted cable Are the g90, TC and amp all plugged into the same power strip? They should be for best performance. What firmware versions are the Tx's and receiver. If not the newest it certainly wouldn't hurt to get them upgraded. Does the problem continue or was it one time only. One time only could point to some specific incident such as bad AC, or strange interference. While the radio cannot produce interference as audio it can get into cables.

When you power the transmitter on and hear the noise is any cable plugged into it? Plug a cable in and short the tip and sleeve on the open end (wrap some tin foil around them). Do you hear the noise now?

I'm not sure you have a problem. The IDs will change as you plug in additional speakers. When you look on the mixer page is everything in It's proper place? Can you reassign speakers from the panel? Blinking otoh is usually a sign that the connection is not good. So methodically go through your cables and make sure none are damaged. It's also possible you have a bad panel jack so make certain the problem is with an individual speaker I would also recommend that you make sure to have the most recent firmware in all the speakers (v1.05) as it improves L 6 connections. In fact, do this first. Just to make double certain I'd also reinstall the mixer firmware.

There seems to be some strange things happening to the forums. I will check with the web department on Monday and find out.

Modes and venues are the bigger questions. .
