6.4DSP Matrix Mixer
Call stations and wall control panels, are connected to the PLM‑8M8 DSP matrix mixer via CAT‑5 cable using RJ45 connectors. The multi channel DSP amplifiers are connected to the DSP matrix mixer either via Amp Link or via the output Phoenix connectors. All other connected wiring must be of a professional quality and preferable screened.
