Monitor outputs dropped mid show

I submitted a support ticket (#TLT-793-38278) for this issue last night, but wondered if anyone else had seen this problem, or possibly have some suggestions for potential user errors I should investigate.

Problem & Setup: I was using my GLD112 (v1.3) tonight at a festival and lost all 5 aux monitor sends during one of the bands. The meters showed signal on all 5 auxes post-compressor but there was no signal post-fader. The faders for all 5 auxes were turned up (around -30). Aux faders were not muted. Aux faders were not on a DCA.

Recalling the festival starting show file did not fix the problem. Rebooting the console and then recalling the festival starting show file fixed the problem.

    I am unaware of any possible user settings that could cause this problem, where a recall did not behave the same as a reboot/recall.
What else could get changed in the reboot?

Monitors were run connected to the AR2412. Only a single AR2412 was connected, no other external devices were connected to the GLD112 except an Apple Airport Extreme connected to the control network. Nothing was on the wireless network except an iPad running GLX Mix. The iPad was turned off (sleep mode) at the time the monitors went dead. Main speakers were working fine, only the monitors were affected. USB stick was in the GLD.

Anyone else seen this?

Did you confirm that there was no signal post fader from within the console or do you just mean nothing came out of the output sockets? The behaviour is exactly as if the master faders were assigned to a DCA that was turned down. I know you checked that, but maybe the error was DCA related, or maybe the fader itself was acting like it was turned down.

Were you mixing monitors from FOH? If so, did the other mix buses keep working?

Chris

Ah, you mentioned the mains kept working. Were you using any other auxes for anything except the monitors?

Chris

Thanks Chris for the help.

I used the touchscreen meters to look at the aux signals immediately before and after the fader. There was signal before the Aux1 through Aux5 faders, and no signal after the aux faders. he faders were ‘up enough’ for the show volume (-30 DBFS).

I only had 4 DCAs setup, none of then are connected to Auxes except my ‘Master DCA’ which controls L,R,M, and an Aux for subs.

Today I made a new fader layer and put all 16 DCAs on it and reconfirmed that none of the DCAs are connected to the monitor axes except my one ‘Master DCA’ fader which was not connected to Aux 1-5, only Aux6 which I use for subs. Actually, there were no subs at this gig so I can’t comment on whether Aux 6 was also dead.

Again, recalling the show file didn’t fix the problem, but a reboot followed by the recall fixed the problem.

To calrify, the subs were on Aux 6. Aux 1-5 were the ones that went dead.

Do you know that aux 6 was working, even though you didn’t have any subs? If it was, lets see what’s different…

Your sub aux would have been post fader, whereas your monitor auxes would have been pre fader.

Obviously the monitor auxes were patched to output sockets. Given that you weren’t using subs, did you have aux 6 patched to an output socket?

Hi Mark,

i had the same problem. I finding it:

  1. IP45/46 pressed button MIX, fader set to 0
  2. Aux1 fader set to 0, from Aux1 nothing signal
  3. Aux2 fader set to 0, signal OK, sound fine

I test all, copy aux2 to aux1, … nothing.

than i random pressed button MIX on aux1 and fader was on -40 (?), pressed button MIX on aux2 fader was on 0 (?). ??? I pressed again mix button on IP45/46 - fader on 0 and aux1 fader on 0, aux2 fader on 0. ???

i play with button mix on input IP45 and mix button on Aux1,2. It is not the same ?

then i control: mix button on aux1 to 0, fader on ip45/46 to 0. sound fine :slight_smile:

Chris, Aux 1-6 were all patched to sockets. Aux 1-5 were pre-fder, 6 was post fader as you suggested. However, since I didn’t bring subs I didn’t have anything being sent to the subs, so there was no signal present anywhere on Aux. Unfortunately, not any useful new diagnostic info here, but a nice try, thanks again. :frowning:

As a full disclosure, this was my first concert on my new GLD112, but I am not a newbie. I have over a decade working regularly on digital consoles.

For fun, I’ve attached my show file which was saved at the time I noticed the monitors went dead, in case anyone wants to look at it.

OK, I guess we can’t upload show files.

Try uploading it here:

Thanks Chris, the show file is there now: https://community.allen-heath.com/groups/gld-libraries/documents/.

Nothing too fancy about the show, 6 auxes, 2 mono and 4 stereo busses, 0 matrixes, LR+C, some preset channel libraries.

Note, the posted show file is for a GLD112. I have no idea what would happen if loaded to a GLD80. Maybe the Bank 1 faders are ignored, maybe it won’t load.

Nothing looks like it should cause a problem, though I’m not liking the editor as much in 112 mode.

I enjoyed the bass EQ =D.

Chris

Yep, with no subs the EQ was a tad ‘bad’. The evidence that reloading the show file didn’t fix the problem, but rebooting and then reloading worked, points to either some ‘safe’ setting or a software/firmware problem.

The only thing similar I’ve seen was an iLive that wouldn’t pass signal to LR from most channels. Three people checked it wasn’t user error, rebooted, etc. It worked again after the bus structure was reconfigured.

The problem you have seems to be at the output fader though.

Chris

I didn’t have the same problem but a screen freeze after i changed the Bus-Settings in a loaded show (not standard show)
Lucky that the freeze happened before soundcheck! Just rebooted the console and had no further problems! But i think a problem like yours can cause by changing the bus-settings without using a standard show! So best will be if it isn’t too complicated to generate a new show from a standard template after a big Firmware update!

I didn’t change the bus configuration mid show, It was working, and then stopped. All I did during the show is ride LR+M mix faders and muck with EQ, comps, & gates, comps on the busses, and FX feeds.

FWIW, I, like many others, have had the screen freeze twice in the shop while reconfiguring the system. I’ve only had it for a week.

I can rebuild my show file, it will take a few hours. I hate to just stab in the dark like that, but I guess it’s good practice. The hard part isn’t building the setup the hard part is documenting what I’ve done already, I’ve made a lot of customizations. Maybe I can load my show file in the editor (offline) and use that as a reference to reprogram the board.

A&H’s official response : “There is not a known issue that would account for this, if the problem persists please contact your local dealer to arrange for a service of the desk and the audiorack, as the fault could be with either of these.”.

Frankly I’m disappointed, I consider this MI-level support. It doesn’t even appear that they looked at the show file. Behringer appears to be providing better support for the X32. As another aside, The same day I got the GLD112 I bought an X32 Rack as an emergency backup console to take to gigs, and for occasional small gigs with no FOH space. Kind of a pity to need to carry an X32 as backup to for the GLD.

I still have my 01V96. It’s been rock solid for a decade. Never had a single problem at a show. Was planning on selling it, maybe not now.

Disappointed,

Well the GLD is still a NEW Product… and sure there will be some more firmware updates to come for a more stable software and more functions! The Workaraound of the GLD is way faster than all the other boards! Even a X32 Standard isn’t that fast, same for X32 Rack! If you will wait so many years like your 01V96 grew now than i’m sure you wan’t have any problems with the GLD!

I’m sorry that i can’t help you but A&H will work on this if this will be a software/firmware bug! sometimes a Hardware problem can be the reason!

The only thing similar I’ve seen was an iLive that wouldn’t pass signal to LR from most channels. Three people checked it wasn’t user error, rebooted, etc. It worked again after the bus structure was reconfigured.

Chris,

By reconfigure, do you mean ‘rebuild the show file with the same bus structure’, or ‘change some random bus settings’,…
