Here is a thing, we have 6 QU16 of which 2 maybe 3 are exhibiting interesting faults.
One is when going from say Mix 1 to Mix 2 the settings of the faders stays on Mix 1, which has caused a few issues.
Two is when going into the faderflip from mix the faders stay where they were making the graphic sound a bit rough.
Now when back in the unit nothing can be reproduced but we have had feedback from several of our engineers saying it has happened to them on site along with jumping fader issue which is described further back in the forum.
The ‘cure’ of hard wipe the desk then re-calibrate the faders has been done, engineers shown and training done but the desks still are doing their thing on site.
Anybody else having this issue? Any fixes? Any cures? Our best guess is the main processor is having a real problem communicating with the faders motors.
Thanks you for your ideas but we had this discussion about power with the show techs and engineers and no other equipment suffered a power related problem (video, audio, Lighting, computers) We did have a brief go in the warehouse with power supply and no problem repeated.
We have sent the desks out on other shows, with reluctance it must be said, to other countries, off generators and similar and still the problem occurs.And then back at home…
We brought these desks as they seem to have many functions for the price but now to add a UPS of quality to sort out a what we see as a design problem makes them not worth the money.
And today yet another desk has been reported as playing up. I’ll let you know the details.
I have to suggest that as a reasonably large operator (6 desks implies some sort of scale) that I’d be wanting to pop a simple camera over the desk to record entire gigs, in the hope of capturing the issue on video.
Thanks for the information on how to act on forums.
Now, we brought these desks to do a job of work not to fault find for manufacturers. If I have to rig a camera on every desk along with a UPS and other diagnostic recording equipment to find a fault on every show I would lose valuable time on the rig/de-rig.
I just would like to know why these desks ore misbehaving.
The firmware is the latest from the site, we are not using the desks with dSnake as the usage is stand alone smaller rooms and so far we have not run the desks with Qu-pad.
We will try the reload of the firmware and let you know.
It appears from the video that the desk is being shut down (crashed) by powering down simply by hitting the power button without doing the Home > Shut down > OK to shut down procedure…BUT…
Since the camera zooms to just the techs LH and it is not showing what his right hand is doing the “crashing the board” scenario is not for sure. IF the desks are being crashed instead of following the proper power-down sequence there is always the chance that something in the OS may be corrupted.
Just a possibility, but worth investigating. Also, when re-loading the firmware it is advisable to get a fresh download rather than jst re-loading what’s on the computer from the last download. But you know that, I presume. Just mentioning it for other interested readers.
Lastly, the USB stick for firmware transfer should be a proper one and freshly formatted. Again I presume you’ve done this and include the recommendation for other interested parties.
I did have a online chat with most of the technicians who have reported faults and some had powered down but on the whole the desk had been left on for from setup until the show when the problems occurred.
Following the power down procedure all the time cannot be done in the real world can it? There are instances were power is out of the operators control.
It still seems that the customer is doing the R&D for Allen and Heath as I have had no reply from Allen and Heath direct on these issues.
Power down can be done correctly in the real world.
There are occasions when the power is outside your control, but they are actually pretty rare. If you find that power is frequently an issue then I’d recommend an inline UPS. Just a little one.
Following the power down procedure all the time cannot be done in the real world can it? There are instances were power is out of the operators control.
I have found no reason why the manufacturer suggested operational procedures cannot be followed in the field or in studio. The path from here seems clear:
File a proper support ticket
Do a fresh firware download and install.
Train your staff to use the proper power down protocol.
Yes, there will be times when someone else pulls the plug on you or the generator goes down, but there really is no excuse for constantly crashing the desk by not following proper procedure. It takes all of an extra 5 seconds to treat your equipment properly.
I am having the same problem. Did they ever get back to about the problem with the console . I’m having same problem I shut down properly . Running current firmware . After rehearsal I’m gonna do a hard reset . My main channel page got stuck to my graphic eq and slammed all graph faders down to match my main channel page
