Bosch PLM-8M8-US Plena Matrix 8-Channel DSP Zone Mixer

The PLM-8M8-US Plena Matrix Mixer is a Bosch DSP zone matrix mixer for public address and background music systems. It belongs to Bosch's public address range.

It takes 4 microphone or line inputs, 3 music sources, and call station or emergency inputs, and routes them across 8 independent output zones, each feeding a PLM amplifier over Amp Link. A Windows PC GUI or iOS app configures the system over Ethernet, and RS485 ports connect call stations and wall control panels directly.
