Found an intermittent possible bug in the PowerCab 212 when daisy chaining two together with a Helix. I was able to reproduce almost 100% for a bit while writing this up, but then sometimes I can’t. ———— Steps: Connect guitar to Helix Connect Helix Line 6 Link out to PowerCab 1 Line 6 Link in using an AES/EBU cable Connect Line 6 Link Out on PowerCab 1 to PowerCab 2 Line 6 Link in Power Helix On, then PowerCab 1, then PowerCab 2. Turn volume up in both PowerCabs to half, and turn up the volume on the Helix to whatever. Make sure both have sound. Turn the volume on PowerCab 1 down to zero and verify PowerCab 2 still has sound. Mute the guitar. Continuing to play appears to negate the issue. Turn the volume on PowerCab 2 down to zero and wait 5+ seconds. Turn the volume on PowerCab 2 back up and wait 5+ seconds. Now try to play guitar. Result? No audio. No signal indicators on the PowerCab 2. PowerCab 1 appears to stop sending signal. Green signal lights appear on PowerCab 1, and turning the volume up works. Restarting PowerCab 2 does not restore audio. You must restart PowerCab 1, and then audio on PowerCab 2 will work again. —————— I tried swapping the order of the PowerCabs in the signal chain and got the same result. Whichever amp is in the middle of the Helix and the other stops sending signal when the volume is set to zero, and nothing comes in to the amp for a bit, but only if the second cab is also set to zero briefly. ————— This is a minor issue, but may you have to restart your PowerCabs between sound check and your show. Or make sure you never set the volume to zero on the amps themselves. Ran into this the first few times I played with the amps live, and thought maybe I had to start them in a certain order. I was playing withy two amps today and investigating a new rattle, and I’ve figured out what’s actually going on for this problem.

So for my own use the best setup I could arrange for sound and feel has been stacking my dual 112+ powercabs. Is it possible for one of the physical volume controls to control power and output to both of the amplifiers. Instead in its current state they both need to be adjusted from each powercab and it would be ideal to override this and function amplifier output from one powercab for both units. This would be helpful and allow for more control from the patches and then the ability to control the total output of the amplifiers on the unit itself , albeit from one unit globally. Any changes for output level outside of the master powercab volume being done on the patch or global settings of the helix. Please inform. Thank you.

Just curious what happens with Line 6 Link and 4 PowerCabs? With 2, it automatically splits the signal into stereo right? If I added a 3rd, does the third get one side? Or does it flip to mono on that one? If added a 4th, does it Go back to stereo? I’m betting no one has done this, and it’s more of a thought experiment. Just thought it’d be interesting to know. I’m trying my bass through my 212 PowerCabs right now, and noticed after my most recent show (using guitar) that I’m getting some rattling in on of the PowerCabs at certain frequencies. Gonna have to crack it open and tape things down I guess. So I set up both of my 212 cabs with my bass and the rattle goes away because I’m turning the Helix volume down to compensate for twice the power. The low end out of two is improved a bit. And obviously the more speakers and power, the better it would handle even more lows. So imagine 4? Have a nice stack of PowerCabs on either side of stage, and maybe 2 more on top for guitar... #drool

I saw some older posts talking about various cables for the Line 6 link. I was wondering if there was any newer info on this. I am currently using a cheap Hosa EBU-010 AES/EBU Digital Audio Cable. I don't have any problems with it, but every time I look at how thin it is, I wonder if using something higher end, such as Mogami Gold AES would work better. Anyone try some of the various higher end cables? Thanks.

Hi I have my dreamrig with JTV, pod hd 500x and the l2m. Is it possible to change the settings of the l2m with link 6 link like changing from PA to acoustic to electirc and so on? If not, maybe a good option for the next ypdate for Pod HD 500x

I've been looking around at the line 6 pod HD500x and the DT25. I really like the idea of going totally wireless so I was wondering if you could use a Relay G series unit in the place of a Line 6 link cable. Is this even possible? [this is my first post, so go easy on me] :) Ben
