Can somebody explain what exactly the Meridian 511 S-Patch box does and why it's necessary?

The 568 manual says you must have it if you run more than two DSP speakers. So if you have a pair of 5000s up front you're okay, but if you slot in a 5000C center channel you suddenly need the 511.

The 565 doesn't seem to have had this "feature".

Any data?

Thanks,
