New Module by Lars Clausen

I'm looking forward to testing this module. Lars intended it to be a new level of high end class d.

You can look forward to my experiences with it as I plan on sharing them on the forum.

Lars Clausen is responsible for this module, and I'd like to stress that it is independant of LCaudio.

Regards,
Chris

The distortion graphs only show for power output up to 100W@8ohms and only show up to 10kHz. However, the amp is advertised as being able to deliver 400Wrms@4ohms, and 650Wrms@2ohms. I would be interested in seeing the distortion graphs at the rated power output, and I would like to see frequency response to 20kHz, not 10kHz. At this point it looks like LCAudio is trying to hide something when they advertise high power and high bandwidth (120kHz) capabilities, but don't show any measurements under these conditions to show how the performance actually is.

I look forward to your results.

Did any of you get any clear answer to:

-Is the same output filter being used at all different switching frequencies?

-What is the standard switching frequency?

-Is the 120kHz bandwidth achievable at all switching frequencies?

-Under what conditions does it perform 120kHz? (power, harmonic distortion, phase distortion, noise...)

[classd4sure]

I think at heavier loads the switching frequency drops and at light loads it's highest.


I think the given graphs demonstrate the advantage of this by showing it''s level of "lowest distortion for certain conditions" which is also presumed to be for example 10W at 4 ohms, which I think even with speakers of 102db efficiency I use alot more than 10watts on average.

Aside from that I do think it would be important to see how it fairs across its full rated frequency and power response for various rated loads.

Sorry guy, I did the same 3 months ago for a multichannel amplifier...Mine is rated at 200W into 8 ohms and 350W at 4 ohms. Variable dead time, so that's mean low dead time at lo power and higher at higher power...Only thing, I dont have micro-processor to watch reliability...But never blow any module as for now. I will sell lot of these module soon, I have over stock...The pic is prototype with fews production module, unfortunately I did not have complete module on hand, all sold!

Oh s**t! I just saw the price...350$ USD!!! Wait guy, I will sell my module for 60$!

This looks great!

I have to admit, I got a little teary eyed when I say the "Quality Policy" - I wish every company do the same. And I know without a doubt that Lars will stand by this policy.

The risc controller looks very interesting.

And SMPS would always be welcomed for those of us who look for pro-sound solutions.

I can hardly wait for Chris' reviews.

Yeah, it seems hand make soldering.. :lol:

What does LC Audio have to do with this? This is a Lars Clausen product from NewClassD, which is a subsidiary to Dexa Technologies, and thus has nothing to do with LC Audio.
