Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems SpeakerLink Connections and Config

I don't have SL or DSP but am thinking about it. I have wondered, since the config program doesn't seem to differentiate between the various SL outputs, is it the DSP that tells the controller what channel it wants?

If that is the case, your idea wouldn't work because you can't set the 5k to "sub".

Am I wrong?

Hi Anders,

Each Digital coax or SpeakerLink output had 2 channels of audio data combined in to one signal (SPDIF, AES/ABU respectfully).
So the speaker is receiving two channels. However, the speaker is then configured to either use channel 1, channel 2 or in some instances (such as a daisy chained mono sub) both.

Dependent on application (i.e. which output from processor):
Channel 1 is: Left or Centre
Channel 2 is: Right or Sub

Yes, I understand that. But if I connect one SL cable for L and R, and another for C and Sub, how does the controller know which SL cable gets which pair of feeds? When I fooled around a little with the config program (but no SL hardware) it seemed as if the controller SL outputs were not labeled or numbered.

If that's correct, the DSP must send back a request, "we are L/R" or "we are C/B" based on how the speakers are configured...

I had intended to ask this question anyway, before this DSP sub question came up. Just engineering curiosity...

Hi again,

Forget your assumptions you are just digging a hole for yourself. The SpeakerLink outputs are labelled.



As you can see from the photo, there are 8 RJ45 sockets arranged in pairs with each pair being dedicated to two audio channels.

For any given pair, it does not matter which way round the DSPs are connected other than the MASTER DSP must be in the 'master' row of it respective socket pair.

The user has the choice whether to run each DSP back to the processor or daisy-chain them in DSP pairs.

In a 7.1 system:
a 'home run' system would use 8 RJ45 sockets.
a 'daisy-chain' system would use 4 RJ45 sockets.

The processor is indifferent on how one connects them up.
It has been suggested that 'home run' provides the best SQ, but I could not hear any difference on my system.

Carl
