Infineon MA12070 Class D

[Toku]

Toku, I think the amps do not come with connectors and cables to the inputs? Any idea what are the specifications for the connectors? My amp modules is shipped and on the way to me.

I contacted the shop in advance about the connector cable and confirmed that it was not included.
I searched on Aliexpress and ordered from the shop below.
The standard of the connector is JST XH 2.54. It is the same size as the 3e audio amplifier board.

Love the dual mono build.

I hope Infineon makes a analog MA12070X model.

But the they do, its the one without a "p" in the end.

TnT i believe the X at the end is what infineon will add to modules that are tweaked with GaN Fet.

Aha - so MA12070Xp for one with i2s input. 🙂

Only 18W at 8 ohm speakers.😕

Only 18W at 8 ohm speakers.😕

Well this is measured at very low THD level.
By the way: 18W is only ~3dB less in comparison to the specified 35 watts. So you will not really notice in real life.

Well this is measured at very low THD level...

That should be OK. It should not be measured with 10% distortion as is often the case now.

Is this filter necessary for PBTL application of this board?

Hi Zek


i guess this filter is included at this board. look at post 103.

i see no reason to use no filtering.

That s true Toku. Indeed it uses Ceramic caps and I have to admit that the amplifier sounds great

Wich amp ic produse better sound for long listening ? I'm considering tpa3255, ma12070, irs2092 etc.

Without any doubt, DrMordor TPA3255 Module with LLC PSU outperforms all the amp I have tested.

This is a must have ! even my Hypex Ncore double Mono is kneeling next to it !

 

[TNT]

What is better do you think?
