Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems 511 s patch

You can often avoid the use of the 511 patch by diasy chaining the comms leads from each speaker.

The advantage of the patch box is that it is a single hub where all comms leads can orignate from so can be placed near the source where the audio leads also originate from. The 565 actually had a patch box built in.

In a 2-ch system it is not required, in a 3-ch system it is often avoided. With surround speakers though it may be more useful.
