Are you operating the router at 5GHz ONLY? Switching to wi-if at 5gHz usually yields much better results but remember this is a wii-if issue and depends greatly on local conditions. The mixer itself isn't playing any part in this kind of problem. Are you keeping the router above "head height" so you maintain good line of sight?

You lose power in the sub compared to what?

No, they can only be used with the new receivers.

Sounds like your tuner has an issue. I know there were some Korg units that had an issue like this. But never heard of it with Boss

You are running in RF1 mode, correct? That's the mode we use for all of our artist units. Does this happen in more than one venue?

OK ... the transmitters work fine but how about the receiver? Are you getting normal audio output from both the main and tuner outs?

Have you tried plugging directly from the tuner output of the G90 directly into the amp? Do you get normal output from the main output? Btw. All firmware updates require using an XD-v75 as it can connect through a computer via USB. Upgrades are free via Line 6 monkey. ( see support tab)

Why would anyone be so dumb as to pack refurbished units but not bother to flash them with the newest firmware?

Probably just a little glitch in production. . Although lots of precautions are taken, there will always be a few units out of every 10s of thousands that will get mis-packed no matter how many inspections they go through.

Yes ... the mix out contains all input sources to the box.

I think you have normal operation. You made a test yourself and did hear 100hz from the top speaker, right? The top speaker is designed to come on only on low frequencies.

I assume that Tom is plugging into the back (power amp module) as he is using an external mixer. I would recommend setting the feedback button to green for music otherwise you will probably hear some artifacts that sound like clicking. The Feedback manager in both Stagescape and Stagesource work to tame the frequency peaks in the system (mic/mixer/speakers) and have a limit as to how much protection they will provide. Typically they will make the situation 2-4 times better that without. But once you cross that line you will experience feedback again. The best thing you can do for free to prevent feedback is to sing and play very close to your mics (within 1 inch). This is because when you are very close to your mic you won't need as much "gain" in the channel to get the volume you require. And anytime you double the distance to your mic you lose 6 dB of potential gain before feedback. So if you move from 1" to 2" away from your mic you will increase your chances for feedback times 4. Likewise moving from 1" to 1/2" will give you 4 times improvement. Don't be afraid to put your lips right on the windscreen. Also I should point out that the likelihood of getting feedback is inversely proportional to the size of your venue (especially with respect to ceiling hight). This is pretty self evident when you think about your own experiences. You probably never get feedback when you play outdoors and you know how tough it is in small rehearsal rooms or clubs with 8' ceilings. The tight space simply reflects way more sound back into your mic, which is what causes feedback in the first place.

Hey Brian Line 6 has a policy that prohibits us from commenting on unreleased products for obvious reasons. Sometimes thing get very close to happening and then they are never released. As far as "glitches". There are no known factors. Sometimes some units develop hardware issues and those are repaired or replaced under the warranty. Sometimes problems are system problems and are cause by hookups with other gear or are caused by local power issues. I don't believe anyone has been left out in the cold. Anyone thinking they have a hardware issue should open a service ticket and get it checked out. That's the official way to get involved with Line 6. For anyone posting an issue here on the board they should expect that it will only be discussed by other users and not the factory. As far as the difference between posting an idea here and on ideascale, when you post on ideascale every idea is catalogued and seen by the product development team. That might happen here or it may never be seen.

Yes you could use the power amps in the XR8600. You just plug from the Mains outs in the Stagescape to the jacks marked "power amp in 1&2" on the XR8600. You woud need XLR to 1/4" cables. How are you hooking up your powered subs at the moment. You should probably run from Stagescape's Mains out to the subs and then from the outputs on the subs up to the power in jacks on the XR8600

An easy test would be to power on the speaker by itself with nothing connected and check for hiss/hum/clicks. There will always be some amount of hiss and it should follow turning up an down on the level controls. That would be normal operation. Then plug in the cables and check again. If there is an increase in noise then the problem is not in the speaker itself but somewhere else in the system. Usually it will turn out to be bad cables.

My best guess is that the input jack has become damaged. I would suggest that you consult with GC as to weather that is covered.

The audio signal will be fine. You will just miss out on the additional features of the receivers.

It sounds like you lost line of sight between the transmitter and the receiver. The optimum position for the antennas is about 6-8 feet above the floor. Also if the performer is holding the transmitter at the bottom and thereby covering the antenna, your range will be reduced. Instruct them to hold the transmitter from the middle up.

Yes, on the ring

You didn't mention ... But have you swapped cables?

Please read post #2

I could work great but you would have to make some modifications. The transmitter would need a power supply. I'm not aware of anything that could drop in directly. My suggestion would be to find an external wall wart supply (such as the DC-1g) and hard wire it to the battery terminals. The maximum input to the belt pack is +8dBu so you would have to make certain you don't send a signal stronger than that. So that basically means if you feed the transmitter from an RCA output you should be fine. But if you feed it from an XLR (or TRS) output you should put a 15 or 20 dB pad in the line (Hosa ATT-448). The antennas supplied with a G50 are 1/4 wave and cannot be used remotely from the receiver. But you can use the antennas that come with the G-90/V75 in their place. Or you could just use G35 receivers and play them on top of the speakers so that they are in line-of-sight.

It's difficult to make exact suggestions without a site visit but I can pass a few suggestions that should apply. Our antennas work well in the horizontal plane but are essentially dead on the top and the bottom (think doughnut). So you don't want to set them too high. Using the P180 units ... they could be focused down to the area of interest. There are also excellent antennas available from RF venue http://www.rfvenue.com/rf-venue-24-ghz-microphone-helical-antenna. This helical antenna can be focused for a longer distance and mounted nearer the receiver. As far as cable, 100 feet is the theoretical max forth smaller LMR-195 cable. But in never like to run at the max. I would recommend using LMR-400 for that length run. Check the antenna white paper in our knowledge base for more ideas.

Likely the sensor switch is stuck. This happens sometimes because all XLRs don't fif the same. You can free it by gently pushing it with a toothpick.
