[jcga]

Ah, OK power amp firmware, not HFD sorry

 

[ds23man]

Firmware, not hfd. Check at downloads on any fusion product page.

Has anyone used an amplifier module separately from DSP/dac? Is it possible to unscrew it and just use for a stereo amp? Is it an ordinary nc252mp module there or a special one with different gains/inputs, etc?

It is proven that some resistance in front of a tweeter may decrease distorsion. To many, this sounds less "fun".

This explains why I've been unable to enjoy some really expensive tower type speakers, the tweeters where distorting heavily much earlier than the mids. Even at relatively low levels.

I can accept some distortion in the bass region, just sounds a bit "more".

So what you are saying is that the speaker manufacturer got their driver levels completely wrong?

 

[KaffiMann]

Yes, I really think so.
It was the last time I went into one of those fancy hi-fi shops, and it's been at least 10 years since. I had a listening session planned and got to listen to a number of different speakers. Quite literally made me run away from several known brands and never return.

Edit:
Heavy distortion on several of the tweeters.

Yikes!

I did that exact thing with the lower powered version, and it works perfectly. Carefully study the application notes for the standalone amp module to ensure you connect the input cabling correctly.

Grear, so the gain is the same as in application notes?

 

[Logic800]

In my case I referred to the NC122MP notes, so best check yours, which I assume would be the 250 series. Another point to note is that the module is naturally in standby, and needs two pins shorting together either permanently or via a switch to power it up, again, refer to the notes for details.

Seems to be rolled back to 1.41.

Did you mean the file isn't listed but can be downloaded by direct link?
I don't see a link in the Downloads section:

Phone problem?

Hi, I'm late to the party, just a few simple questions...
I need a solution to run linear phase crossover for a 3 way system. Is there a product for me by hypex or similar?

I believe a fir convolution can be used to linearize phase of fusion amp's filters. For example, Rephase can generate such filters and Roon or Jriver can apply them.
