Meridian AC12 Accessory User Guide

Meridian AC12 is a versatile audio connectivity device designed for Meridian systems. It allows you to connect recent Meridian sources with SpeakerLink output to older Meridian Digital loudspeakers that lack SpeakerLink, or to integrate non-Meridian sources like PCs with SpeakerLink loudspeakers. The AC12 also enables multichannel SpeakerLink setups with both SpeakerLink and non-SpeakerLink loudspeakers, providing flexibility for various system configurations.

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 selfcontained; it does not need a power supply or mains connection.
