Introduction

In choosing the 566 24-Bit Digital to Analogue Converter you have

acquired a component that combines major advances in digital audio and

engineering design. The 566 24-Bit Digital to Analogue Converter provides

three digital inputs and one optical input, and uses the latest 24-bit dual-

differential delta-sigma digital to analogue converter, combined with

balanced Class A output amplifiers, to give extremely low distortion.

This guide is designed to enable you to obtain the best possible results

from the unit, whether your requirements are simply to convert the output

from a compact disc transport, or to work with inputs from several digital

sources.

If you have just purchased the 566 24-Bit Digital to Analogue Converter,

you should first turn to the section Setting up the Digital to Analogue

Converter, page 11, which explains how to unpack and install the Digital to

Analogue Converter correctly.

The Meridian 500 Series

The Meridian 500 Series is a unique system of digital, analogue,

and video components designed to meet the demand for

absolute quality, ease of use, and lasting value.

The flexibility of the Meridian 500 Series is such that you can

assemble a system as simple or as complex as you need,

perfectly suited to your musical and environmental requirements,

and which can be added to or changed at a later date should

your requirements change. The 500 Series is also compatible

with the existing Meridian 200 Series and 600 Series

components.

Each Meridian 500 Series component is housed in a matching

slim line case. Front panel controls provide access to the most

important functions, and the full range of functions is available

from the Meridian System Handset using a simple and intuitive

control interface.

500 Series communications

The Meridian 500 Series includes a sophisticated

communications link, to ensure that any configuration of units

will work together as a fully integrated system.

The 500 Series communications system allows you to control

any combination of units using a single handset, and ensures

that your commands from the handset are interpreted

unambiguously. It also allows all the units to be switched off

from the front panel of any unit in the system.

Professional features

The 500 Series also provides features for professional users,

including RS232 computer control and balanced connections.

The following pages give examples of four suggested

configurations to illustrate the flexibility of the Meridian 500

Series.
