Well i think STK is a good choice at all but not this one...
This one haves 0,7%THD ..
This is too much.
Look at this one:
http://www.electronics-lab.com/down...k/STK4048XI.pdf
If you make 2 channels whith this one you will be comletly satisfied...
it have 150W @65V - 0,008%THD.
IT is a HibrydIC Clas AB.
I`m currently searching for a bridging technik for 4048XI..
If someone have one pls tell me. |

I just built the example circuit for the STK4122 II , but only the left channel for now.
Tested it out and its not working at all. Do I need some sort of pre amp? just a pot?
Or do I just have to finish off the right channel :)
btw my Velodyne subwoofer uses STK chips as well, so they must be alright. (although your right, THD is a little high).
thanks
edit: I think my problem is I have no ground on the transformer. Only V+ and V-. hm |
