CheaperLink

Hacks for easing the use of "legacy" Meridian Digital Active Loudspeakers over structured wiring. The name is a reference to SpeakerLink, Meridian's own system for this, but it is not electrically compatible at all.

Repository structure

wiring-diagram.svg - a logical diagram of how a system is wired.

hub - Heart of CheaperLink, connects to system controller and exposes RJ45 for each pair of speakers.

bridge - converts CheaperLink back to Meridian Legacy, one for each speaker

test-board - a small cheap hack to test the S/P-DIF to balanced design

R11 - A semi-unrelated clone of the Meridain 511 Slave Patch Box, which is used to connect multiple speakers together on comms to a central star hub rather than daisy-chaining them.

libraries - contains symbols and footprints specific to this project, mainly mechanically imported from LCSC or drawn by my own fair hand.
