I’m setting up some modifications to the PA system at cat’s cradle in Carrboro, NC. We have (4) I-tech 4X3500 amps powering VTX V20s and G28s - each amp powers 2-3 tops and 1-2 subs (guess is that this distributes power/current/heat across all 4 amps, rather that subs on their own amps). I have the original show file from the initial set-up. It’s currently being run as a full range system, but want to allow the option to run the subs on aux instead.
I had no trouble hooking a laptop with Performance Manager to the amps with a network switch, receiving the current configuration and saving it as a new performance file. I modified the file with a new set of amp preset files that split the amp inputs so that the sub channels are discreet, and saved again as a new performance file. Loaded it to amps from performance manager, hooked up the lines and it worked - subs ran from separate channel that tops.
Then the trouble began.
I tried to show the head engineer how to load the full range presets via the amp control panel (so that he could switch from one to the other without having to rely on the laptop - we haven’t run cat-5 from FOH yet to facilitate control) and it seemed to erase all presets - the amp displayed -40 dB levels on all four channels, which was the first indication that something had gone wrong. I checked performance manager - and all the amplifier preset information was gone (as I recall). So I loaded up the original performance file and sent it to the amps to get them back to the state they were before I made changes.
Help, please.
I plan to keep working with it, and can provide the Performance Manager file(s) if someone can figure out what I did wrong. All I want to be able to do is be able to have a “full range” and “subs on aux” preset on each amp, and be able to switch between either via amp directly and/or using performance manager.
Is this a firmware issue?
Should I use different software - audio architect?
Surely there’s a simple ‘one click’ method of switching between full range and subs on aux that other venues use?
I also have other questions about our Harmon-JBL system, but can start a new thread if that’s more appropriate.

Are you saving the file on a separate preset on the amp or an amp file?
It's been awhile since I have touched either Audio Architect or Performance Manager but I recall saving amp files.

I’m creating new presets for the amp using ‘PRESET MANAGER’ button on the amp panel window within Performance Manager, working offline. As a precaution, I also saved the amp files for each from within the amp panel window - so that i could load it from a USB drive, and as an extra layer of backup. I then saved the whole performance file and I’m assuming it saves the amp presets As well, but maybe not?
