Any update on this thread? I'm looking for TH118 settings for ITHD12K and would love to know what was at the end of the rabbit hole.
Good question.
A little while back one of the other guys was doing a setup and when he measured the output voltage it was VERY close (like within a volt or so) of what the settings said.
HOWEVER a little bit after that I used the same meter (HP400) to measure a ITECH HD that we had in the shop and it was off a fair bit. I check my meters (I have a couple of HP400s and others) kinda often and they are reading the same-or at least close enough for me not to worry.
Not as bad as with the ones with different software-but still off-and a bit more than what Chad had measured.
Some Crown engineers told me (back when I first having issues) that the actual gain of the amp could vary by a couple of dB, and that the limiter had no reference to the output. It was acting like a stand alone limiter in front of the amp. Even though the block diagram says different.
So if the gain of the amp is varying a couple of dB, then that could throw off the numbers in the DSP.
So I am a firm believer in MEASUREMENT.
I have a feeling a change was made in the software (as I have heard through the grapevine that I was not the only one complaining about it)
So make of it what you will.
