Problem w/ C2 Level Autocalibrate.

[Nemesis]

Hello
Have a little problem with Level Autocalibrate on my C2.It calibrates alright until
it reach the sub.Then it will try over and over again and stating "Level too low for calibration". This can't be the case, cause it sounds like the sub is gonna blow!
I checked with my RadioShack and the level is way up when it's on the highest before it starts over.This problem arised suddenly from one day to another.
Anyone had this problem,or heard about it?

Hei,

It sounds like your sub has a high pass filter enabled that prevents the C2 from doing proper calibration. Please let us know the brand & model of your sub. This will make it easier to figure out what's wrong...

Hello
My sub is a SVS PB 10.I also use a Velodyne SMS-1.Calibration worked OK with this setup,and I can't remember changing anything before the problem arised.

Well, assuming you didn't change anything, it is possible that something got messed up in the C2 settings. Did you try to unplug the C2 for 1+ minute and try again? Resetting to factory settings and redoing the calibration is also a good start.

I turn off all my HT stuff every night.Sets everything in standby and kills the power with a mains switch for the HT.
It's not a big deal really.I can use my RadioShack meter for the sub,but I felt the Auto calibration was more accurate.
It's midnight here,I'll try some more tomorrow.
Thanks for your help.

Nemesis, are you doing the Parasound auto-calibration before you use the SMS-1? You first want to calibrate before you equalize. Using my Behringer Feedback Destroyer, I set it to straight pass-through so it's essentially turned off and doesn't alter the signal whatsoever in the slightest. If in doubt, I'd even bypass the equalizer (SMS-1) with your cable routing for the calibration part.

Yes, I do recommend a combination of the auto-cal and an RS meter for proper calibration. Auto-cal first, then fine-tune with the meter. But I don't change the sub setting based on the RS meter, only the other channels.

Thanks for the reply.
I used to Autocalibrate before and after the use of SMS-1.As the autocalibrate do not work for the sub now , I will have to rely on the RS meter.
I'll try later today or tomorrow some other filter settings and even bypassing the SMS-1.

Bypassed the SMS-1 and connected the sub direct to the C2.Still the same
problem.When the calibration tries to calibrate the sub,it plays louder and
louder and the C2 at last states "level to low to calibrate",and the bass level from the sub is thunderous before it starts over.

Hmmm... Sounds like the microphone isn't picking up the sound. Have you tried to replace the battery in the microphone with a fresh one? (If the battery is good, then the next step would be to check that the mic cable connection is good. Can you use the mic to calibrate the other speakers?)

Peter

[Nemesis]

I can use the mic to calibrate the other channels.No problem with that.

If you haven't tried a brand new fresh battery, do that... (A long shot, but possibly a weak battery could limit the frequency range of the mic. IMHO that's just as good guess as anything else).

If a fresh battery doesn't help, then I'd look at doing a full factory reset of all the settings...

Tried a new battery earlier tonight,but no help in that. Full factory reset?
Don't know if it's worth it.I'll see if I get some spare time.

Thanks for the suggestions. :T

Somehow I doubt a reset will help. The problem could be a bad mic or a problem with the mic input stage of the C2. If the unit is still under warranty, it might be worth getting it fixed...

True, but Parasound readily states that these processors are like computers. Sometimes after a while you just have to reset and flush out all the electronic "junk".

If you're worried about the trouble of resetting everything after a full reset, you can always use the Halo Control program to save all your settings and then re-upload again when you're done. (if you haven't done this yet, i do highly recommend it, and I believe that a computer and Halo Control are ESSENTIAL for proper C1/C2 setup)

Based on what we're discussing, and if you're not having any other problems with the C2, I'd doubt that there's anything wrong with the C2 itself. Perhaps the microphone?
