Hello All!
I am new to the forum, and I urge you to help me.

In my system there is a zone processor Meridian 218, it is connected to the main audio system via an analog output.
I use a Intel NUC with ROCK (with iPad as Roon remote)
I recently purchased DSP420 speakers, and would like to connect them to a Meridian 218

As I understand it, for this I need an SpeakerLink to Legacy DSP cable SL-M5 + SPDIF adapter like this ...

Where can I get it?

Replacing the internal board with this would be a better option DSP420 RJ45 PCB SU0359.

I tried to connect the DSP420 speakers to the Meridian 218 digital output via SPDIF, however, in this case I cannot adjust the output volume ...

Perhaps there are other options for adjusting the volume via iPad (Roon Remote)?

I will be very grateful for any help in this matter!
