Introduction
The Meridian 565 Digital Surround Processor is unique in being the first
completely digital surround-sound processor, and it defines the standard
for both music and cinema performance. To achieve this we have
combined the latest techniques in high-precision analogue electronics and
digital signal processing with a careful analysis of all types of recorded
music. The result is a system that produces impressively realistic and
exciting reproduction of music and cinema sound with support for all the
current two-channel and multi-channel audio formats. These include PCM,
Dolby Digital (AC-3), DTS, and MPEG, as well as support for several
proprietary processing modes. MLP (Meridian Lossless Packing) format is
also available as an optional extra.
This User Guide explains how to operate the digital surround processor to
give the best results from your music and cinema sources.
For information about installing and setting up the digital surround
processor refer to the accompanying Meridian 565 Digital Surround
Processor Installation Guide.

Introduction
The 565 Digital Surround Processor is part of the Meridian 500
Series of advanced 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 requirements, and with the ability to add
to it or alter it at a later date should your requirements change.
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 Remote 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 includes features for professional users,
including RS232 computer control and balanced connections.
The following pages give examples of eight suggested
configurations to illustrate the flexibility of the Meridian 500
Series.

Sample configurations
The first step you can take in exploring the benefits of surround
sound is to add a centre speaker to the left and right speakers of
a conventional stereo system. An ideal choice is the Meridian
M60C Active Loudspeaker, which can be connected directly to
the 565.
The digital surround processor takes advantage of the additional
speaker to create a more realistic and stable three-dimensional
image of the original recorded sound for outstanding music and
cinema reproduction.

The next step in creating a surround system for cinema and
music reproduction is to add a pair of rear channel surround
speakers, to provide cinema effects and add spatial information
to music reproduction.
An ideal starting point is a pair of wall-mounting or bookshelf
speakers powered by a Meridian 556 Stereo Power Amplifier.

The ultimate analogue surround system consists of two pairs of
Meridian M60 Active Loudspeakers, in conjunction with a
Meridian M60C Active Loudspeaker. These speakers can be
connected directly to the 565 to provide a complete five-speaker
surround system.
The 500 Compact Disc Transport provides an ideal addition to
the system for music listening.

A THX system is designed to recreate the original cinema sound
in your home. It uses a mono subwoofer to enhance the bass
from the main left and right speakers.
If your main speakers have a good bass response you can
choose to use the subwoofer only for the cinema presets, for a
more natural reproduction of music.

The ultimate Meridian Digital Theatre uses a 565 in conjunction
with four or six DSP6000 Digital Loudspeakers and a DSP6000C
Digital Centre Loudspeaker.
Each speaker accepts a digital input from the 565, and uses twin
digital-signal processors for remarkably distortion-free
performance and a breathtakingly realistic sound.

The 562 Digital Control Unit is the ideal control unit for use with
the digital surround processor for a complete multimedia
system.
It provides direct digital inputs for digital sources, such as the
586 DVD Player and LaserDisc sound, together with precision
Delta-Sigma analogue-to-digital conversion, for conventional
analogue sources such as the 504 FM Tuner or video sound. It
also includes video switching for composite and S-VHS signals,
such as from a satellite receiver, LaserDisc player, or video
recorder.

The digital surround processor can be upgraded to provide fully
digital decoding of 5.1 channel AC-3 sources, to give the
highest-possible sound quality available, combined with
comprehensive support for the flexible AC-3 decoding options
and user features.
The Meridian 519 Demodulator converts the AC-3 signal
provided on the RF LaserDisc output, and provides an optical
output to connect to the digital surround processor. When no
AC-3 signal is present it passes the LaserDisc optical output
directly to the 565.
The 565 automatically selects an AC-3 preset when an AC-3
signal is present.
