I have no evidence to suggest whether the AC12 is an AC11 in reverse or a small device to colocate with each speaker. We are verging on speculation here smile

Looking at the photos or the processor rears, the AC11 and speaker-link equipped speakers and I am struggling to deduce how this will all wire up.

I think speakerlink is a balanced stereo SPDIF implementation on RJ45, presumably with MHR encryption. And I think it works as both a mono or stereo feed to any DSP speaker (or as a stereo feed between devices) so they can be fed either as a star network or daisy-chained. The speaker will need to be configured to tell it which channel to pluck out as now over conventional SPDIF.

Would some-one with speakerlink installation experience please enlighten me?

This will matter for those installing cabling now.

In the spirit of Spinaltap, I would like to confirm that I am not involved in the corrupt theft of a global sport.
