| I have never heard of it. Out of curiosity, what does this mean? The pulse width is controlled digitally? Sounds like a good idea to me. |

I've got two of the Spherex 5.1 XBox amps, which use the DDX-8001. I was able to piggy-back a board that has a micro and USB interface. So far I can control the volume from a VB.net application. Working on the biquads next.
The current version of the chip is the STA-30813, successor to the STA308. ST has sold a lot of these chips and they are used in many home theater systems. I wish I knew which ones so I could buy them to re-use the amplifier boards. The JVC model TH-S2 uses the STA308 and I know that at least one budget RCA amp used the same chip.
These are very nice amps, and with 10 digital biquads you can build some nice crossovers and do a lot of EQ. |

the DDX-8001 has 8 channels,The AMP board I used is a 6 channels AMP+2 channels Phone AMP
Just use the DDX-8001 ,you can achieve all the functions. |
