RESLOVED> I have recently installed an AHM-32 for a fairly basic matrix mix of the audio in our performing arts venue. This includes routing for the main PA, subs, fills, balcony delays and assistive listening system. I have created a couple of redundant presets and chosen “ALL” in recall scope and clicked “Unit startup preset” and selected the desired preset. The power has gone out in our building a couple of times and upon startup no presets are stored and all routing and configurations are gone. I have tried storing and recalling and double checking all the boxes. I can pull the power and when power is restored, all the presets are completely cleared. Of course I can reload my saved config file, but I am wondering if there is a way to store the configurations to be saved if the power goes off. Thanks.
Hi Juniper,
Would you be able to reach out to us at support@allen-heath.com please? This looks like you might have an issue that requires a bit of troubleshooting. It isn’t normal behaviour for the config to be wiped on a power outage.
Just sharing that this one is resolved - if anyone else has the same issue, please get in touch with support. Thanks!
Edit, April 2026:
Just in case anyone comes across this thread in the future, as someone reached out to us to ask…
The issue in this case was that the factory reset dip switch was in the wrong position and the AHM was factory resetting on every boot. This was a human error in the manufacturing process (The switches are used in the test process after the hardware is manufactured) and not a hardware fault.
If you’re getting similar symptoms where your config is resetting on every boot, look for red text on your System → Status page that says “DIP Switch 1 Set”
The switches can be found on the rear of the unit - remove the IO port cover OR the IO option card (if you’ve got one fitted). The switches are inside the IO port on the right hand side. Make sure they’re all in the off position.
