Hello,
i updated quite a few I-Tech amps from FW 1.2 to FW 2.01 last week. I think having 20 Presets and access to the delay setting directly at the amp is nice improvement...
... but i also have a few questions and i hope that somebody has an answer:

1) After the update to FW 2.01 the TCP/IQ Utility (ver 8.0.0.3) shows "*** No OIF file***" under description. Under version it shows "ITA20112", but the firmware date field is blank. Also the amplifiers are not found if i do a discovery from IQwic (also ver 8.x).
Checking the firmware version at the amp (monitor menu) it says: Display: v.2.0.1.12 and DSP: v.2.0112 .... so i assume the update was succesful. So why the strange message behaviour with TCP/IQ Utility and IQwic?
(the amps seem to work fine.)

2) After loading a preset at the amplifier and then cycling power, the amplifier will sometimes return not to the last setting (before powering down) but to the setting that was loaded before recalling the preset. If it does return to the "right" preset the gain attenuation might be different from what is was before powring down.
Has anyone had similar experiences?
Is there a (software) switch to make sure the amp always returns exactly to the same state after cycling power?

3) Where can i find detailed documentation on all the values and settings that are availbale for the I-Tech fw2 to use with the IQwic surface (all the items that show up under "Edit object control list")?
Especially i am looking for a way to display if the "average power limiter" is working or not (like a gain reduction meter). Is there any way to do this?

Thanks + Greetings from Germany!
Tobi

1) After the update to FW 2.01 the TCP/IQ Utility (ver 8.0.0.3) shows "*** No OIF file***" under description………

*The “***No OIF file***” found statement indicates that the .oif control file used for that version of firmware was not found by the software so it doesn’t recognize the amp.
When you downloaded the firmware there was also included in the zip file a folder that contained the new .oif files. These files need to copied into the C:\Program Files\IQ Systems\IQwic directory.
(You will need at least the IQwic 8.0 software.)


2) After loading a preset at the amplifier and then cycling power, the amplifier will sometimes return not to the last setting (before powering down) but to the setting that was loaded before recalling the preset. If it does return to the "right" preset the gain attenuation might be different from what is was before powering down………

*After trying this many times I haven’t been able to duplicate this issue.

*There isn’t really a detailed description listing available for controllable objects. However a meter can be set up as a “PIP Ouput Gain reduction meter” from the “Edit Object Control List”

Thank you for the quick answer!
Your hint about the oif-file solved that problem.
Also the PIP output gain reduction meter is exactly what i was looking for.  smile.gif

I've tried this with different I-Techs and i think this problem only occurs with no network connected: I load a preset and exit to the main screen. Then i power down the amp, and after powering up again the amp goes back to the preset that was loaded before (like before the preset recall). Same thing happens to attentuator settings sometimes. Any ideas?

Thanks!

Maybe it has something to do with the "Memory Backup Configuration"? With FW 1.2, 1.3 and 2.0 there was a "Memory Backup Enable" in the Object Control List Editor. It is not there anymore in FW2.01.
I've never used this function before, but according to the descritption in the I-Tech Manual this flag could cause the "strange" behaviour.
Is there a way to enable/disable the memory backup with FW2.01?

After getting this further information of the amplifier not having a network connection I have been able to duplicate this issue with firmware version 2.0.1.12 and have reported it as a bug to our engineers.
I will let you know what they come up with as soon as I have an answer.

"Memory Backup Enable" is still in the .oif file but we are now filtering it out in the "Object Control Editor List" as it is something that could cause major issues if it were accidentally set to Off. When the Memory Backup Enable is Off the amplifier will revert to the factory default settings. That is to say there would be no settings like filters, limiters etcetera and the level controls would be turned up so the amp would be passing full range. This is not something that most people want their amp to revert to when they power down their system.

Hello David,
i was wondering if there is any progress on this topic?

As you wrote above most people don't want the amp to revert to something different after cycling power...
Right now it is more or less unpredictable to say what preset will be loaded after powring up the amp. As I described above the amp switches back to some random preset after cycling power (with no network connection).
I would call this bug quite dangerous!

Please let me know if there is a solution to avoid this problem.... if not i think i have to downgrade the firmware back to 1.3 .... i guess i also have to rewrite all my presets, right?

Thank you very much!
Greetings from Germany!

Hi Tobi, David

I have the same issue with the powering down and back up and it's really the reason, why we can't use it on touring. I would be really glad, if we would have a fast solution.

BTW: How do you link the 2 Gain Attenuators in SA?


Thanks

I noticed this too.  If I had the amp just plugged into the switch, it would load fine.  So a temporary work around could be having switches in all the racks.  So this is probably still something related to the network card right?  Similar to that old bug that wouldn't let the amp work right w/o it being plugged into the network?

Hi David, our amps have exactly the same problems as described formerly on this topic, please advise if we need to downgrade all the amps we have, a total of 52, or if we should wait for a solution from the engineeering departement soon. We are starting to have lots of work, so this is a BIG problem, as we rely on the dsp of the amps to do all the systems alignment and tuning.
Also, as a sugestion, it will be a good ideia that you advise your customers in this matter, I wouldn't know about it if I didn't browse this forum ocasionnaly.
Are you going to Frankfurt Musik Messe? I'm going to be there and discuss some details with you.

i would also like to say that i find the bug VERY annoying.  i run 4 itech's @ every gig and it gets very, very annoying having to reset the gain manually at the beginning of the night (instead of the amp remembering it after last power down from the previous night).

please, please, PLEASE fix!

just a quick update to let you know that firmware 2.03 has been released.  when you power cycle an amp now, the amp gain is at the same level it was before it was cycled.  works for me biggrin.gif
