Module burn-in test.upload picture,sound good！

Did you find the triangular output with the ceramic SMD caps also at very low output levels?
If it happens only at higher output levels, then it is probably just the traditional voltage derating behavior of most ceramic caps.
NP0 should not show much drop of capacitance, X7R already poor for large audio signals, Y5...again worse.

Oh,I know Npo/X7r/Y5v,I design mixer and SMPS use different CAP.I only use ceramic cap manfacture by TDK.

My freind mail me they use this module get 600W,Real power out?I never get so much power out with this module(we call sw1400),when I increase iuput singal 1.6vrms,I get 50Vrms/8Ω/1kHz,45Vrms/8Ω/1kHz,I never found it can delive out 600W.
I call him just ago.I know reason.he change my output inductor with double red/grey 39mm toroidal core,400uH inductor and 2u/wama cap.they only use it drive subwoofer.I follow with him! super audio man!

Are you adjust you input sensitivity fit for USBDAC output,They have high level input,about 8Vrms,you module is strongly structure.can you fit together widely digital source.

很漂亮，有卖吗

My friend asked me develop new one.I do it before China New Year coming.upload picture .2OZ PCB,Immersion au，blue silk screen,Use WIMA MKs series CAP in output stage and decoupling 。 brunofix aluminum heatsink。
My friend call it" Genius 500".I have test all paramter.47V﹫4Ω ≤1%THD (about 552W/4Ω )work state indictor( ready/clip/OTP).

Our new module use Tripath Ta3020 will finish.500W/4Ω。

bwaslo · 26th February 2010, 03:05 AM

Willl you be selling the 500W amps also, authlxl?

Not that I really need yet another amp, (in fact I just broke down and bid on the TAS5630 amp in chassis you have on ebay - it's due to end in an hour or so, I couldn't just watch it stop at that price). But 500W, more power is more power...which is always good, right? I notice the heatsink fins on the new amp, does it get warm?

What do you think of the Tripath as compared to the TI chips, is Tripath better?

I have relist on ebay just ago,GENIUS 300 TAS5630 CLASS D AMP - eBay (item 330408770277 end time Mar-07-10 21:23:49 PST)

Thanks!
