Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Streaming Hardware with Roon Application Is this even possible?

Hi All
I have one Meridian DSP5200HC and nothing else Meridian - I have an Allo DigiOne Signature (inc RPi4 4GB) and a Nucleus+ as Roon core.

I have connected
Allo DigiOne SPDIF out to Speaker SPDIF Digital Input 1 And
Allo DigiOne running DietPi USB port to USB-Serial (pl2303) to Null Modem cable to RS232 on Speaker

Does anyone know if I can play music out through this speaker and control the volume of course. The Allo DigiOne would act as the music source.

I look forward to your thoughts

It's been a long time, but I was able to accomplish this with a pair of DSP5000 speakers.

Here are a couple of references:

"Roon Extension to provide source switching, standby, and volume control for Meridian Audio's range of devices via RS232"

https://github.com/RoonLabs/roon-extension-meridian

Some discussion on the Meridian Roon Extension at the Roon Community.

The RPi4 USB port on your Allo endpoint does not have anything to do with Meridian comms or volume control. You would need at least a MSR (remote) or M controller unit, which would be an expensive way to go. -WRONG!-

I have used DigiOne coax out into these speakers successfully -which I think set a “65” volume level by default- so you could get up to that OK level and control through whatever software you use to play from the Allo.

EDIT: Just because I never learned how to implement the Roon Meridian extension

This setup sounds similar to yours; Allo DigiOne Player, DSP8000 and TRENDnet TU-S9 USB to Serial cable (along with a null modem adapter) --

It works.

Hi,

Unless your Allo DigiOne SPDIF output can be set to mono, I think you might need a processor to use a single DSP speaker.

"Can you set Roon to playback in mono"?

Ok, good to know. I hadn’t thought of that option. Still, worthwhile looking for a second speaker.

Thank you all who considered my post and shared their thoughts

To my surprise and disappointment - the version of the speaker DSP5200HC I inherited seems to have no RS232 port!

Digital SPDIF in/out via RCA
Meridian Comms in/out via BNC
Meridian SpeakerLink in/out via RJ45

Is it possible to control the speaker through the comms BNC ports in the same way?
OR
Would I need a AC12 (expensive) or is there something similar (and cheaper)?
OR
Other ?? would getting a Meridian remote help?

I've never tried serial control over SpeakerLink, but maybe this post (#287482) can give you some ideas --

Something to wire up the RS232 Dtype to the SpeakerLink RJ45

This does work to provide volume and source selection with Roon. I tested it a while back with a pair of DSo33. Also Had the final post in the post reference above. Some how I advertanly deleted my post. Lots of support on Roon community to get it setup.
