Introduction

The digital surround controller provides an extremely
comprehensive range of digital signal processing options for
decoding both analogue and digital audio signals and
processing them for multi-channel reproduction. These are
referred to as DSP presets, and are designed to provide the best
results with a range of different types of music and film material.

In addition to selecting built-in DSP presets, the digital surround
controller allows you to create your own presets based on the
standard ones. For example, you may want to add more delay to
the rear speakers to create a more spacious sound. You can
store your modified preset with a name of your choice, and
recall it for use at a later date.

This section gives information about each of the built-in DSP
presets, and gives recommendations for the best preset to
choose for different types of material.

Multi-channel digital sources

The 561 Digital Surround Controller supports the three
alternative multi-channel digital formats currently available,
which encode up to 8 different channels onto a digital signal:
Dolby Digital (AC-3), DTS, and MPEG Audio. It also supports
Meridian’s own MLP format.

Dolby Digital

Dolby Digital, previously called AC-3, is the preferred sound
format for DVD video, and is widely used on LaserDisc
soundtracks. It is also the audio standard for US digital
television.

DTS

DTS uses a carefully designed audio compression technique to
encode five channels of audio onto a digital signal. The DTS
format is used to encode multi-channel film soundtracks on
LaserDiscs and DVD video discs.

DSP presets

Introduction

9

In addition, a high data-rate version of DTS can be used to
compress five channels of CD-quality audio into the same space
as two channels of unencoded sound, allowing a DTS music CD
to provide over an hour of five-channel music, at a quality
indistinguishable from conventional CD.

MPEG Surround

MPEG Surround is the preferred audio format for DVD in PAL
territories, and along with Dolby Digital is a contender as the
standard for music and performance videos on DVD worldwide.
In addition, it is widely available in US satellite broadcasts.

THX

THX versions of Dolby Digital, MPEG Surround, and DTS are
provided to give a better match between the original soundtrack
and typical domestic listening conditions.

MLP

MLP (Meridian Lossless Packing) is a format designed for DVD
audio which allows multiple audio channels, of up to 192kHz
24-bit quality, to be stored on a DVD without losing any
information. It can also be used to store four-channel audio on a
standard CD without any loss of quality.

Multi-channel sources encoded onto
two channels

Several systems have been developed for encoding multi­channel sources onto a standard two-channel analogue signal
so that they can be reproduced by a conventional stereo
system, or decoded with special equipment for multi-channel
reproduction. The 561 Digital Surround Controller provides
decoding of the two most important of these, Ambisonic and
Dolby Surround. Although the channel separation cannot be as
good as with the digital multi-channel formats, the 561 produces
excellent results with these formats.

Pro Logic

The Pro Logic preset is recommended for decoding Dolby
Surround encoded video and LaserDisc soundtracks, and films
on television. Such materials are usually identified by a Dolby
Surround symbol on the packaging, or displayed on the film
before the programme.

10

Introduction

TV Logic

TV Logic provides user-adjustable steering, and is
recommended for use with TV broadcasts that are not surround
encoded, where Pro Logic may give reduced intelligibility.

THX Cinema

THX Cinema enhances Pro Logic to replicate the sound of a
dubbing stage or theatre, whether or not the other equipment in
your system is THX approved.

Ambisonic

Ambisonic decodes material specifically encoded for surround
sound reproduction, using a two-channel stereo-compatible
encoding. Recordings encoded in Ambisonic format are
available on CD from several sources including Nimbus Records
and York Ambisonic. Some radio broadcasts are also broadcast
in Ambisonic format.

Conventional stereo sources

The digital surround controller can also accept a conventional
two-channel source, such as music on compact disc or a video
soundtrack, and by analysing the information in the signal
separate the two-channel recording into multiple channels to
give better reproduction and a more stable spatial image.

Four alternative DSP presets are provided for reproducing
material originally designed for a conventional stereo pair of
speakers, and which preset you choose largely depends on your
own personal preferences.

All four presets use similar procedures to extract the surround
component of the original recording, which is delivered to the
rear surround speakers, and side surround speakers if present.

Music

Music uses a special technique developed by Meridian to divide
the sound between the left, right, and centre speakers and give
a wide, spacious sound. We recommend this option for large­scale music, such as orchestral and choral music.

Introduction

11

Trifield

Trifield uses a different processing technique to give a stable,
three-dimensional image, with the ability to adjust the width of
the image. Because of its precision we recommend this option
for solo, chamber, or vocal music.

Super Stereo

Super Stereo provides a form of Ambisonic decoding suitable
for material that is not specially encoded. We recommend this
option for multi-miked or multi-tracked music, such as rock
music.

Music Logic

Music Logic provides user-adjustable steering to give an
exciting sound with many types of music. We recommend this
option for studio-produced music, ie material not produced
using natural soundfield recording.

Special DSP presets

The digital surround controller also includes the following special
DSP presets, for specific applications:

Mono and Academy

The Mono and Academy presets are designed for reproducing
mono materials through a centre speaker, so that any high­frequency hiss or clicks are centrally localised.

Mono is designed for mono recordings, and multi-language
LaserDiscs and video soundtracks.

Academy is designed for early black and white film
soundtracks. It includes equalisation designed to correct for a
high-frequency balance in some old black and white films.

Stereo and Direct

Stereo and Direct are provided for comparison with the other
DSP presets. Direct uses just the main left and right speakers
for traditional two-speaker stereo reproduction. Stereo, in
addition, uses any subwoofers in the layout to enhance the bass
or to protect small speakers.

When not playing, the digital surround controller should be left in
the standby state. This uses a negligible amount of electricity,
but ensures that the components of the digital surround
controller operate at maximum efficiency from the moment you
start.

If you are not going to use the digital surround controller for
several days you should switch the unit completely off at the
back panel, and disconnect it from the AC power supply.

To switch on from standby

● Press Source (front panel), or select a source by pressing the

appropriate source key on the remote; eg DVD.

If the digital surround controller is part of a Meridian system it
will automatically switch on any other unit in the system, such as
the CD player and Meridian DSP loudspeakers.

To select a source

● Press Source (front panel) until the display shows the source

you require.

For example:

DVD

Alternatively press the appropriate source key on the remote;
eg DVD.

After a short delay the display shows the currently selected DSP
preset and volume setting.

For example:

Digital 56

The digital surround controller mutes the sound while you
change source.

By default the following 12 sources are available: CD, Radio,
DTV, TV, Tape 1, Tape 2, CDR, Cable, DVD, VCR1, VCR2, and
LDisc.

Selecting a source

Using the digital surround controller

18

The audio input, video input, and DSP preset associated with
each source can be configured using the Meridian Configuration
program; for more information refer to Configuring the digital
surround controller using a computer, page 79.

To switch to standby

● Press Off on the front panel or the remote.

The display will show:

To mute the sound

● Press Mute.

The display will show:

Mute

To restore the sound

● Press Mute again.

Alternatively, the sound will be restored if you adjust the volume.

The digital surround controller adjusts the volume in precise
steps of 1dB, where 9dB is equivalent to doubling the loudness.
The current volume setting is displayed in dB on the front panel
display, and can be varied in the range 1 to 99dB.

When you first connect power to the digital surround controller
the volume is set to 65, which is similar to the midway position
of the rotary volume control on a conventional preamplifier.

A setting of 87 corresponds to THX reference gain, the level at
which film soundtracks are mixed. For normal to high-level
listening you should expect to use volume levels in the range 60
to 90.

To change the volume

● Press A or V (front panel), or the red A or V keys on the

remote.

As you adjust the volume setting the display will show the
current volume level.

For example:

Music 70

Adjusting the volume

Using the digital surround controller

Each source has a set of DSP presets associated with it, one for
each of the alternative audio formats: two-channel (PCM), Dolby
Digital, DTS, MPEG, and MLP.

When you choose a source an appropriate DSP preset is
selected for the incoming audio format.

For example, if you have selected the CD source and are playing
a conventional CD, the Trifield DSP preset will initially be
selected. You may then wish to choose a different DSP preset,
such as Music or Ambisonic.

You can also change the default DSP preset associated with the
source; see Changing the DSP preset for a source, page 33.

To change the DSP preset

● Press Preset (front panel or remote) to step between the

different DSP presets.

The display shows the current preset;
for example:

Music

You will be able to choose any of the predefined DSP presets, or
any user-defined presets you have stored.

Changing the DSP preset

The following table gives the sequence of DSP presets for each
audio format, followed where appropriate by the abbreviated
name used on the display:

In addition to being able to change the source, volume, and DSP preset,

the digital surround controller provides a sophisticated range of more

advanced adjustments for each DSP preset, to allow you to change the

characteristics of the sound to the settings you want.

This chapter explains how to change these advanced parameters, and

how to store them permanently so they are available whenever you want

to use them.
