Does anyone have a wiring diagram for the "Network" connectors on the back panel of my 1989 M20 active speakers. (There are two marked "left" and "right" very similar to these shown on a M30 https://www.meridian-audio.info/viewphoto.php?compid=183 )

The Meridian specs indicate they are 2x 6way audio and data. The sockets look to my amateur eye as if they take a British Telecom 631A plug with a side mounted hook but I could be wrong. https://m.media-amazon.com/images/I/617bmEc1D-L._AC_SL1464_.jpg

The RCA connector on one speaker has broken off again (in my move from USA to Europe) and combined with the purchase of a new TV (LG OLED55C9PLA which does not have RCA outputs) I'm wondering if I can use these Network connectors to get sound out of my TV and if so, how to wire them up?

My TV has HDMI and optical outputs. I've got spare HDMI cables I can cut open and splice to the appropriate network cable.

Thank you in advance for any replies.

Audio over HDMI and optical both are digital signals. Your legacy M20s are strictly analog. They predate the advent of Meridian's first digital active loudspeakers. The way forward would require a DAC with a built in volume control at minimum and a repair of the broken off RCA jack on the one loudspeaker.

The RCA socket is soldered to the input circult board, This can break in shipping if not protected properly. It is however, easily repairable by a skilled technician for not too much money.

Although I am interestd to find out those BT phone socket labled Network were every used?
