Meridian AC12 User Manual

Introduction
The AC12 allows you to connect up a system consisting of both
the latest Meridian SpeakerLink products, and earlier Meridian
products using Meridian Comms over either 5-pin DIN connectors
or BNC connectors.
The AC12 is a passive component and so is completely self-
contained; it does not need a power supply or mains connection.
