Introduction

The 558 Multi Channel Power Amplifier provides five discrete power

amplifiers in a single enclosure, and is ideal for multi-channel surround

systems. Two pairs of channels can also be operated in bridge mode, for

over twice the power output.

The 558 Multi Channel Power Amplifier uses a unique feedback topology

and precision local error correction system. It includes two massive twin

wound toroidal transformers, and the unit has full thermal, load, and DC

protection on every output.

Each of the five channels provides either balanced or unbalanced inputs,

and these can be selected individually.

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

from the unit in conjunction with the other units in your system.

Introduction

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 with the ability to add to it or change it 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 remote, and ensures that

your commands from the remote are interpreted unambiguously.

The communications system also allows you to extend your hi-fi

system into two or three rooms, with the ability to control the

sources in one room from the controller in another room.

Professional features

The 500 Series also provides features for professional users,

including RS232 computer control, and balanced connections.

The following pages give a sample configuration illustrating the

flexibility of the Meridian 500 Series.
