It's an interated audio procesor (on a A7N8X-E mobo)

and the handbook says:

"MCP-T southbridge integrated audio processor unit+Realtek ALC650 6-Channel audio CODEC"
It has three sockets on the rear panel:

1. S/PDIF output jack
2. Surround L/R audio jack
3. Centre/LFE audio jack

The DeaD Altec Lansing VS2121 set-up did not connect to the centre/LFE jack, but it did have a sub-woofer.

My criticism of the the dead set was that they were to 'thin' at the top end and too 'woofy' at the bottom - good for games perhaps but not audio reproduction i.e. films and music.....

..suggestions please )
