Installing 562
Introduction
The Meridian 562 Control Unit and 562V Multimedia
Controller are part of the 500-Series of advanced high-fidelity
equipment.
The 562V Multimedia Controller is a version of 562 that
incorporates an additional video switching board. This manual
describes the operation of both units.
In purchasing a Meridian 562 Control Unit or a 562V
Multimedia Controller, you have acquired a refined piece of
equipment that will continue to bring you listening pleasure for
many years. This manual will enable you to get the most from
it.
Owners of 562 can have the unit upgraded later to the ‘V’
version.
About this manual

About the 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 requirements, and with the ability to
add to it or change it at a later date should those
requirements change. The 500 Series is also compatible with
the existing Meridian 200 and 600 Series components.
Each Meridian 500 Series component is housed in a matching
slim line case. Full access to all functions is provided from the
front panel controls and from the Meridian 509 or System
handsets.
The Meridian 500 Series includes a sophisticated
communications link, to ensure that any configuration of units
will work together as a fully integrated system.
Installing 562
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. Any unit can be designated as the controller
for the system, allowing you to position the other units out of
range from the handset beam if desired. It also allows all the
units to be switched off from the front panel of any unit in the
system.
Unpacking the 562/V
On opening the carton, you should have found the following
parts:
• Meridian 562/V Control Unit
• Power cord
• This manual
• 500-Series communications lead
If any of these items is missing, please contact your dealer.
We suggest that you retain the packing carefully as it
provides maximum protection for the unit in transit.
Installing your 562/V
General precautions
Before carrying out any installation, you should ensure that
the 562/V is marked with the correct voltage for your local AC
supply. Should this not be the case, do not proceed – but
contact your dealer.
6
As a general rule, you should not make any connections to
the 562/V, or to any other component in your system, whilst
the AC power supply is connected and switched on.
Customising features
The 562/V is very flexible. You have the opportunity to
significantly customise its functions. In the end this gives you
a preamplifier that exactly suits you.
The Meridian 562/V is not a product that you are likely to use
stand-alone, you are quite likely to be using some other
Meridian components and getting the best out of the system
will require a little thought.
The section ‘Customising 562/V, an overview' on page 12
describes the options in detail. Obviously, when you have set
up 562/V to your needs, you will be aware of the differences
from the standard configurations.
We recommend that you first get to know the 562/V using one
of the standard setups, and by working through this manual.
Do not be afraid later to experiment with customising – we
have given you a simple way to get back to where you
started! (See page 16).
562/V as provided has nine standard configurations that we
call Type settings. Each Type gives a different set of options;
this feature is described fully on page 16. There are many
more than nine possible configurations for 562/V, but these
were chosen to give good starting points for customising.
By selecting a Type you automatically reset all custom
settings for 562/V to that default.
Installing 562
562/V has five operating modes (not to be confused with
setup Types):
•
Normal
•
Standby
•
Type
•
Config
•
Gain
Normal and Standby are the everyday operating modes: the
basic operating instructions refer to these.
Type, Config and Gain are used to make choices about the
way 562/V works. These are described later in the section:
‘Configuring 562/V, an overview' on page 12.
Connections
There are four types of connection that need to be made to
the 562:
• power
• analogue audio
• digital audio
• communications.
In addition 562V requires you to make connections of:
• composite video
• S-video
• video control via SCART
Audio connections need to be made to other components in
your system. Communication connections have to be made to
most of the other Meridian components in your system in
order for them to act as one system. The connections to your
7
562/V are very important and care should be taken in
deciding which connections to make.
Connection details for a wide variety of systems are described
in the sections following page 30.
Siting
We recommend the following guidelines for location.
• The 562/V should not be placed on top of a power
amplifier.
• If you intend to use a moving coil LP input keep the lefthand-side of the 562/V as far as possible from other
mains-operated equipment. See help item on page 50.
• Avoid sites where it would be subjected to direct sunlight
or where it is near a heat source, e.g. a central heating
radiator
• Avoid sites where the 562/V could be subjected to strong
magnetic radiation, like near a power amplifier.
• Not too close to a television, or where connecting cables
may be subject to, or cause, interference.
Tip In common with all digital products, the 562/V emits
some radio-frequency signals. For this reason, try to keep all
power cables and network leads away from audio, antenna
and loudspeaker cables. Some time spent laying out the
cables carefully will repay you with the best possible
performance later.

amount of power. However, when you are not going to
use your system for an extended period of time, e.g. when
you are going on holiday, we would advise you to
disconnect it from the AC power supply.
Checking
Before turning on the power, check once again that you have
made all the connections correctly and that you have not
disturbed any existing connections in the process.
Switching on
The power switch is located directly next to the power inlet on
the right-rear of 562/V.
1. Turn on the power switch at the rear of the unit. A small
point on the display should now be illuminated.
•
If there is no display
Check the integrity of your power connections, including any
fuses in your supply. If the standby point is still not illuminated
and the rest of your system is functioning, contact your dealer
for help.
Standby
The entire 500-Series is designed to be left connected to AC
power at all times.
1. This standby state ensures that the components operate
at maximum efficiency from the moment you start
listening. It is perfectly safe and consumes a negligible
Basic operation of 562/V
Note 562/V can be used with or without Meridian digital
loudspeakers like D600, DSP5000 or D6000. When it used
alone as the main system control unit it is normally the
‘System Controller’ and operates exactly as described below.
Systems including digital speakers always designate the
speakers as System Controller and there are some functional
differences. The section ‘Using digital speakers with 562/V' on
page 36, describes how the operation differs from the
following description.
Selecting a source
1. press Source until the input you require is indicated
2. release Source
Selecting a source will bring 562/V out of standby.
Putting the 562/V in standby
1. press Off, the coloured key on the 562/V
or
press Standby on the Remote Control
Using 562
Coming out of standby
To start up the 562/V from standby
1. Select a source from the front panel or using the Remote
Control. Tapping Source once brings the 562/V on with
the last-used source selected.
or
If the 562/V is part of a Meridian system, bring any
component out of standby. For example start up a
Meridian CD-player.
Adjusting the volume
The standard 562/V does not have a volume control. If you
want a variable output, making it very like a conventional
preamplifier, then you need to fit the optional DAC module.
Ask your dealer for details.
When used in a system based on Meridian digital speakers
which is operating in 500 communications mode, the volume
keys on the front of 562/V will operate the speaker volume.
If you have a DAC option fitted, or are using digital speakers
in 500 mode you can adjust the volume on the front panel of
the 562/V.
9
To decrease the volume
1. press , the left hand volume key on the 562/V
or
press the bottom red key on the Remote Control
As you adjust the volume setting, the display will change to
show the current source and volume level. For example:
would indicate that you were listening to
a Compact Disc at a volume setting of
65. The volume level displayed will count up or down and
ranges from 1 to 99. Each step is 1dB.
CD65
If you have selected a different display, the display will then
revert to your selected information.
Subjectively a volume increase of 9dB is equivalent to a
doubling of loudness. Each volume number represents about
a 11% change in loudness; nine steps to double loudness. In
a traditional preamplifier using a rotary volume control the
mid-way position offered between 20dB and 30dB of
attenuation. On 562/V 20dB attenuation is at volume number
79, 30dB at 69. For normal to high-level listening you should
expect volume numbers in the region 60 to 90. For this
reason 562/V starts at power-up with volume number 65.
To increase the volume
1. press , the right-hand volume key on the 562/V
or
press the top red key on the Remote
Note When 562/V is set up for use with D600, DSP5000 or
D6000; volume, balance and mute are handled by the
speaker and 562/V will not respond to the Remote control.

Muting the sound
Tape Copy
The mute facility cuts off the sound by setting the volume
level to zero, but the signal will only be muted if you are using
the DAC option, or if 562/V is used with other Meridian
components like digital speakers or surround decoders.
562/V can be arranged to feed any one of the standard
sources to the tape outputs independently of the source to
which you are listening. Where possible the tape signal will be
available on both the analogue and digital tape outputs. In the
case of the 562 Multimedia Controller, the corresponding
video signal is also sent to the VCR tape outputs, allowing
Tape Copy of a video + sound combination.
To mute the sound
1. Press Mute on the 562/V or the Remote Control. The
output will mute and the display will change to:
Mute
To restore the sound
1. Press Mute a second time, either on the 562/V or the
Remote Control.
The volume level and display will be restored.
or
Use the Volume keys.
Changing the display
The 562/V has three display modes. To change the display:
1. Press Display.
The 562/V will cycle through the displays:
• Source and first volume number
• Source only
• Display blank
Note Depending on whether you have fitted the DAC option,
or on whether you have connected both analogue and digital
outputs of your source products, there may be circumstances
where some combinations of different sources may not be
listened to and copied simultaneously. This is explained in
detail on page 35.
To change the copy setting:
1. Press Copy.
The 562/V will cycle through the options:
• CSrc, meaning Copy Source – i.e. what you are
listening to
• CAtt, meaning Copy Attenuate. Tape outputs are
muted.
• C CD, then a series of options to copy specific
sources.
Note Copy can also be used to provide a second independent
output from 562/V for 2-room or simple Multiroom
applications.

Customising 562/V, an overview
562/V is a very sophisticated device with a huge number of
options to allow you to set up exactly the system you need or
to experiment with new possibilities.
Programming 562/V is a straightforward process and you
should not be timid about experimenting. Although the setup
is stored in non-volatile memory called EEPROM, the
EPROM (which you cannot change) contains default Type
settings and you can return to these at any time.
Restoring default settings
1. Switch off any power amplifiers that are connected to
562/V.
2. Switch off the 562/V using the power switch on the back.
Customising
3. While pressing the Off key on the 562/V front panel,
switch the power on again. The display will read:
Type
4. Release the Off key
At this stage you can change the Type from 1 – 9 using
the ▲ and ▼ Volume keys; see details on page 16.
5. Switch off the 562/V using the power switch on the back.
6. After half a second, switch the 562/V power on again.
Caution Some power amplifiers are very susceptible to small
surges that may result from the process of switching a
preamplifier on and off. Some – like the Meridian 205, 555 or
605 incorporate DC-offset protection that may be triggered by
this process. Meridian active or digital loudspeakers are
inherently proof against these surges and need not be
switched off. In general digital products like power amplifiers,
recorders etc. will be unpredictable when they have the digital
signal interrupted.
562/V has three setup options; Type, Config and Gain. These
together with Normal and Standby give the 562/V five
operating states. The following sections give an overview.
Type: an overview
Type just described, restores one of the default settings. No
further actions are possible.
13
Config: an overview
Config mode is used for setting fundamentals of options and
control. Consequently in Config the outputs of 562/V are
muted while you make the necessary choices. The choices
available in Config are outlined in the following sections.
Config: control settings
In Config you can make selections that effect the way 562/V
responds to certain keys. The main choices of this kind are:
• whether you use 500 or 200 communications protocol in
the system. See page 20.
• whether the 562/V is to auto-configure, or you will
determine the controller in the system. See page 36.
• The ‘address’ of the product.
• whether or not there is an internal or external DAC fitted.
• choices on how the volume control works.
• how the product treats the handset ‘Menu’ keys
• whether the unit has video switching
• whether there is a Meridian CD player in 200 mode. See
page 22.
Details of these are described in the sections referred to.
Config: sources and inputs
In Config you can make selections to do with sources, e.g.
• how many inputs will be active
• which sources you can select
• which key on the remote control selects which source
• the Logo for that input on the 562/V display
Customising
• the physical input connection to 562/V including by
implication whether they are analogue or digital.
• the secondary analogue input for any digital source
• the comms type of the source, i.e. whether it is a Meridian
controllable source like CD or Radio
• the address for that source product
In addition, for a 562V Multimedia Controller, you can make
selections that tie the video and sound sources together, e.g.
• which video inputs is selected for each source
• the status of the ‘function select’ outputs for each source
to control the TV monitor.
Gain: an overview
Gain mode is quite different from Type or Config in that the
preamplifier actually functions in this mode. In Gain the front
panel controls operate normally – with the exception of the
Volume keys. Copy does not function in Gain.
Gain is used to adjust the level of analogue sources fed to the
A/D converter.
Digital inputs have a fixed sensitivity defined by the digital
data. Analogue inputs however should have their levels
adjusted so that the best use is made of the dynamic range of
the Analogue–to–Digital converter built in to 562/V. Best
results will be obtained if the analogue gain for each input is
set to provide the largest signal that does not cause
overloading or clipping.
The ‘flat response' analogue inputs like Radio, Video etc.
have four choices for sensitivity; 0.5V, 1.0V 2.0V and 2.5V for
full-scale. Phono inputs using the optional Moving-Coil or
14
Magnetic (MC or MM) module in input A1, also have four
settings.
Note An important feature of Gain is that you can adjust the
analogue input and output settings while listening to the
music. When you feel you have the correct combination of
settings you can revert to Normal which protects the settings.
Note The input sensitivities for the 562/V digital preamplifier
are not expressed in the same way as those for analogue
counterparts. Caution should therefore be used in comparing
these sensitivities. The input level for the 562/V, in common
with other digital equipment is expressed in terms of full-scale
in the digital signal – i.e. more equivalent to the input overload
point of an analogue preamplifier. See specifications on page
48.
How to customise 562/V
562/V needs no customising to become operational. Once
you have your system established you may wish to review the
customising options in the section ‘Customising 562/V, an
overview', page 12.
Although the 562/V comes configured as a standard digital +
analogue – digital preamplifier, there are a very large number
of different configurations possible. This section tells you how
to change the configuration.
Customising
Customising, general procedure
562/V has five operating modes (not to be confused with
setup Types):
•
Normal
•
Standby
•
Type
•
Config
•
Gain
Normal and Standby are the everyday operating modes: the
basic operating instructions refer to these.
Type, Config and Gain are used to make choices about the
way 562/V works. These are described in the section:
‘Configuring 562/V, an overview' on page 12.
How to change to Type, Config or Gain
To change to Type, Config or Gain you use the same basic
procedure.
1. Switch off any power amplifiers that are connected to
562/V.
2. Switch off the 562/V using the power switch on the back.
3. While pressing the specific key for the operating mode
you want on the 562/V front panel, switch the power on
again.
562/V will display a message to inform you which mode it
is in.
15
4. Release the key
At this stage you can make the adjustments required.
In step 3, the front panel key is:
Type – press and hold Off.
Config – press and hold Display.
Gain – press and hold Mute.
Normal – do not use any key!

How to change back to Normal
To revert to Normal .
1. Switch off the 562/V using the power switch on the back.
2. After half a second, switch the 562/V power on again.
Customising with Type
A full customising process
A full customising process will generally involve using all the
configuring modes of 562/V. A full procedure is as follows.
1. Change to Type and select the configuration closest to
your requirements.
2. Change to Config and make choices about:
• keys, displays, inputs.
• control options
3. Change to Gain and make choices about:
• analogue input sensitivity.
4. Change back to Normal.

Customising 562 using Config
Selecting Types
1. Switch off any power amplifiers that are connected to
562/V.
2. Switch off the 562/V using the power switch on the back.
3. While pressing the Off key on the 562/V front panel,
switch the power on again. The display will read:
Ty.1
4. Release the Off key
5. Use the front-panel and Volume keys to move the
selection between Types 1 – 9.
6. When you have the Type you want displayed, wait one
second for 562/V to action the choice.
7. Switch off the 562/V using the power switch on the back.
8. After half a second, switch the 562/V power on again to
restore Normal mode.
Customising using Config
In Config you can review and change settings to do with
communications, control and the hardware options you have.
In Config you also make choices about the number and types
of sources, what the display shows when you select them etc.
The 562/V is initially programmed to Type 1 and all Types set
up the source configuration as shown in the previous Tables.
How to use Config
1. Switch off any power amplifiers that are connected to
562/V.
2. Switch off the 562/V using the power switch on the back.

In Config mode:
1. Press Display until you see a display like:
SA=1
This means the system address is 1. The Meridian 500
comms system allows for up to eight systems operating on
the same network. Unless you are setting up a Multiroom
system, or are advised to do so by Meridian support
personnel, we suggest you leave this on address 1.
Note This setting has no meaning in 200 comms mode
Setting the product address for 562/V
In Config mode:
1. Press Display until you see a display like:
PA=1
This means the product address is 1. The Meridian 500
comms system allows for up to eight products of the same
type operating on the network. Unless you are setting up a
Multiroom system, or are advised to do so by Meridian
support personnel, we suggest you leave this on address 1.
Note This setting has no meaning in 200 comms mode
Note When customisation is complete, switch the power off
and then on again to restore Normal mode and to save what
you have done.
NDAC
This means there is no internal DAC (digital–to–analogue
converter) option fitted and that you have not fitted an
external DAC.
For guidance on this question see Page 35.
2. Use the and , Volume keys to choose between:
• DACT, either an external DAC (like the Meridian 203,
263 or 563) is connected between the digital tape
output and the DAC socket (used as an input), or, an
internal DAC option will be configured in Tape mode.
This mode guarantees that any source can be copied
to the analogue tape outputs irrespective of the
listening source or secondary inputs.
• DACV, internal DAC option only. The internal DAC has
a variable output, that appears on the DAC socket.
Use this setting if you want 562/V to function as an
analogue-output preamplifier with volume control from
the remote control and front panel.
• DACF, internal DAC option only. The internal DAC has
its output fixed at 2V and the output that appears on
the DAC socket. Use this setting if you want a fixedlevel analogue copy of the main digital output.
• DACH, internal DAC option only. The internal DAC has
a variable output, that appears on the DAC socket. In
this case the output level is controlled only by the
Customising 562 using Config
volume keys on the front panel of 562/V, and this
setting is ignored by the rest of the installation. Use
this setting to drive headphones from the DAC output.
Setting the Volume mode for 562/V
In Config mode:
1. Press Display until you see a display like:
VolM
In the 500 comms system there is provision for two volume
controls, main and secondary.
2. Use the and , Volume keys to choose between:
• VolM. Volume main means that the volume control in
the DACV option (above) will follow the main system
and respond to the red keys on the remote. Shifted
(secondary) volume commands will be passed on to
another product.
• VolS. Volume secondary means that the volume
control in the DACV option (above) will follow the
second volume control in the system and respond to
the shifted volume command on the remote. An
example of an application of this would be where
562/V is not the controller – as for example in a D5000
system – and you want to change the 562/V variable
output from the remote control.
For further details on shifted commands see the manual
supplied with the remote control.
If in doubt choose VolM.
22
Setting the Menu mode for 562/V
In Config mode:
1. Press Copy until you see a display like:
N
In the 500 comms system there is provision for the menu key
(remote control) instructions to be passed on by the
controller, either because it does not use menus, or because
a shifted menu command has been created.
N means that menu instructions received from a
controller (like a D5000) will be ignored.
For further details on shifted commands see the manual
supplied with the remote control.
Setting a Video version
In Config mode:
1. Press Copy until you see a display like:

b.
is the network operating in 200 mode?
If the answer to a and b is yes, choose CD?Y otherwise pick
CD?N.
Setting up sources
For each of the twelve source selection keys on the Remote
control you choose a display Logo and a primary physical
input connection – and by implication – signal type. In addition
for digital sources you may set up a secondary analogue input
connection that 562/V may use for the analogue tape copy
signal. (This is necessary if you do not have the DAC option
fitted or externally connected – see page 35).
In the case of the 562V, for each of the twelve source
selection keys on the Remote control, you choose the video
input and monitor control (FNSEL) outputs.
Normally as shown we set the CD key to give a CD display
with the D1 (Digital 1) input selected. You may however wish
to display CDR for your main CD player and to connect it to
D2 or one of the analogue inputs. In a 562V, selecting CD
leaves the video switching unchanged, since CD has no
associated picture we choose, in this case ‘last valid
selection’. See page 27.

Setting up Gain
Customising using Gain
In Gain the 562/V operates as a preamplifier and you can
adjust the input levels whilst listening.
How to use Gain
1. Switch off any power amplifiers that are connected to
562/V.
2. Switch off the 562/V using the power switch on the back.
3. While pressing the Mute key on the 562/V front panel,
switch the power on again. The display will show:
Gain
4. Release the Mute key, the display will show the normal
Standby condition:
.
5. Now use the 562/V normally until you are happy with the
selections described in this section.
6. When customisation is complete, switch the power off and
then on again to restore Normal mode. In Normal mode
the settings you have made will be retained and cannot be
changed without going back to Gain.
29
Setting the sensitivity for analogue
inputs
Analogue inputs to 562/V are converted to digital signals in a
precision Analogue–to–Digital (A/D) converter. The best
results will be obtained if the largest possible signal is fed to
the A/D converter. To allow this to happen we have provided
adjustable analogue input sensitivity.
By setting the sensitivity you also arrange for all sources to be
approximately equivalent in volume when you switch between
them.
To help you set the inputs we have provided a red light on the
front panel labelled ‘Level'. The Level light illuminates when
the peak input signal is 3dB below (about 70%) full scale.
To change the sensitivity of analogue inputs
In Gain:
1. Choose the first analogue input you want to adjust, e.g.
select Radio. (For LP see page 40.)
2. Use the and Volume keys on the front panel to select
levels of 0.5V, 1V, 2V or 2.5V.
3. Use the 562/V to listen to a wide range of material – in this
case try a few radio stations. Set the sensitivity to the
lowest voltage that you can. A good setting is the lowest
one where the Level light flashes rarely or never.
4. Repeat this process for the other analogue inputs.
5. When customisation is complete, switch the power off and
then on again to restore Normal mode.
Here are some guidelines:
• Meridian 204; use a sensitivity of 1V.
Setting up Gain
• Meridian 504; use a sensitivity of 2V.
• Analogue inputs from fixed-level digital sources like CD
players, D/A converters, digital tuners etc.; use 2.5V.
• Inputs from tape recorders or VCRs; start with 2V.
The strongest reason to have the maximum input fed to the
A/D converter is to have a good loudness match between
analogue and digital sources. The 562/V signal path
analogue–analogue has a full 16bit dynamic range. It will be
most unusual for an analogue signal to have this dynamic
range. For example FM radio is equivalent to 13bits and vinyl
LPs only achieve the equivalent of 11bits. If you are
particularly concerned not to overload the A/D converter then
experiment with lower sensitivities (i.e. bigger voltage
numbers). See also page 40.
Audio connections
There are four types of connection that need to be made to
the 562/V.
• power, see page 8.
• analogue audio, see page 30.
• digital audio, see page 33.
• communications, see page 32.
In addition 562V may require connection of:
• composite video, see page 42.
• S-VHS video, see page 42.
• monitor control, see page 33.
30
Analogue audio connections
Analogue connections are made:
• from analogue sources to the analogue inputs of the
562/V
• from analogue outputs of 562/V to your power amplifiers,
active loudspeakers or analogue recording devices like
tape-recorders.
Analogue high-level inputs
Analogue inputs should be connected using high-quality
screened cable. For advice on the type of cable we suggest
you consult your dealer and the manual supplied with the
source equipment.
Warning. We strongly recommend the use of well-screened
coaxial cable. Certain ‘audiophile' cables are not screened.
Screened cable will minimise RF interaction with your system
and will give more predictable results.
1. Make analogue connections from each of your sources to
an appropriate analogue input on 562/V. Take care to
connect Left and Right correctly. The normal conventions
are:
• left channel is the top one of a pair.
• right channel is marked red.
The analogue inputs to 562/V are labelled A1–A7. These
inputs are electrically identical and can have their sensitivity
adjusted in Gain. An exception to this is if you have fitted a
phono option, in which case A1 will have sensitivities
Setting up Gain
31
appropriate to Moving Magnet (MM) or Moving Coil (MC)
cartridges.
Turntable connection
Meridian has a range of suitable digital interconnects
available as accessories. We recommend you do not use
cables intended for analogue connection since these do not
usually have the degree of shielding or an impedance of 75Ω.
Cable intended for UHF applications like antenna down-lead
is also unsuitable since it does not shield adequately in the 1–
30MHz region.
1. Connect the pickup connections to the 562/V input
labelled A1 and be sure that in Config the logo chosen is
‘LP’.
2. Connect the turntable or tone-arm ground wire to the
technical ground socket next to the A1/LP input using the
4mm plug included with 562/V.
3 Adjust the input sensitivity in Gain as described on page
29.
In the case of LP inputs, the gain choices are 0dB, 2dB, 8dB
and 14dB. The following table relates these settings.
Warning. We strongly recommend the use of well-screened
coaxial cable. Certain ‘audiophile' cables are not screened.
Screened cable will minimise RF interaction with your system
and will give more predictable results.
Digital audio connections
Digital connections are made:
• from digital sources to the digital inputs of the 562/V
• from the digital outputs of 562/V to your digital power
amplifiers, digital loudspeakers or digital recording devices
like DAT, DCC or CDR.
Digital connections should be made with high-quality 75Ω
screened cable.
For advice on the type of cable we suggest you consult your
dealer and the manual supplied with the source equipment.
Warning. We strongly recommend the use of well-screened
precision coaxial cable. Certain ‘audiophile' cables are not
screened. Screened cable will minimise RF interaction with
your system. Unscreened cables for digital connections may
cause illegal levels of RF interference.
Digital input connection
1. Make digital connections from each of your digital sources
to an appropriate digital input on 562/V. The digital inputs on
562/V are labelled:
• D1 to D5 for the five cable inputs.
These inputs are identical in performance and are assigned in
Config.
Digital output connections
1. Make digital connections from each output to the
equipment you have chosen to follow it.
• Main and Tape for the two cable outputs.
Connections
These outputs are functionally different. The second Digital
output is intended for a digital recorder since it follows the
Copy source.
Video connections in 562V
Setting up Audio-Video installations is a relatively new and
complex subject. We suggest you read the section of this
manual called "Setting up a video system" on page 42. If you
are in doubt or confused about these connections contact
your dealer or Meridian technical support.
Video connections are made:
• from video sources to the video inputs of the 562V
• from the video outputs of 562V to your monitor, TV or
projector and to any VCRs.
Video connections should be made with high-quality 75Ω
screened cable.
For advice on the type of cable we suggest you consult your
dealer and the manual supplied with the source equipment.
Meridian has a range of suitable video interconnects available
as accessories. We recommend you do not use cables
intended for analogue connection since these do not usually
have the degree of shielding or an impedance of 75Ω. Cable
intended for UHF applications like antenna down-lead is also
unsuitable since it does not shield adequately in the 1–30MHz
region.
32
Warning. We strongly recommend the use of well-screened
precision coaxial cable. Certain ‘audiophile' cables are not
screened. Screened cable will minimise RF interaction with
your system. Unscreened cables for digital connections may
cause illegal levels of RF interference.
Video input connection
1. Make video connections from each of your video sources
to an appropriate video input on 562V. The video inputs on
562V are labelled:
• V1 to V6 for the six composite inputs.
• S1 and S2 for the two S-VHS inputs.
Note The composite (phono) and S (mini-din) signal paths in
562V are completely separate. You cannot therefore switch
between them. If a source uses a composite input, then the
composite monitor or VCR outputs must be connected and
selected on the target equipment. Similarly using S inputs
requires connection and selection of the S monitor and VCR
outputs.
Video output connections
1. Make video connections from each output to the
equipment you have chosen to follow it.
• There is a Monitor output for both the composite and S
paths. Connect a suitable cable from the Monitor outputs
you are using to the appropriate video inputs on the TV,
monitor or projector.
Connections
• There are two VCR video outputs for the composite and S
paths. Connect a suitable cable from the VCR outputs you
are using to the appropriate video inputs on any VCRs.
Note The composite (phono) and S (mini-din) signal paths in
562V are completely separate. You cannot therefore switch
between them. If a source uses a composite input, then the
composite monitor or VCR outputs must be connected and
selected on the target equipment. Similarly using S inputs
requires connection and selection of the S monitor and VCR
outputs.
Monitor control connections in 562V
The 562 provides two switching outputs to allow automatic
selection of the monitor inputs.
These control signals switch between 0V and approximately
+11V dc and have a source impedance of 1kΩ – they are not
therefore intended to directly operate relay switching although
an auxiliary box could do so.
The control voltages are arranged to meet the SCART Peritel
standard. See page 33.
1. Connecting a simple insulated single-core wire from one
of the ‘Function Select’ outputs of 562V to pin 8 of a
SCART input on the TV, monitor or VCR will usually allow
that input to be automatically selected or de-selected by
the 562V, with obvious ergonomic benefits. Normally this
involves fitting an extra flying lead to a standard SCART
cable. Your dealer should be able to provide this.

For further explanation we suggest you read the section of
this manual called "Setting up a video system" on page 42. If
you are in doubt or confused about these connections contact
your dealer or Meridian technical support.
Communications connections
Communications connections are only made to other Meridian
equipment. The following sections describe the major points.
To connect to other Meridian 500 Series
equipment
1. Connect one of the COMMS sockets on the rear panel of
the 562/V to one of the COMMS sockets on another 500
Series unit, using the 500 Comms lead supplied.
2. Connect all the 500 Series products together in this way to
form a chain (not a loop). The order in which they are
connected is not important.
If the system is to operate in 500 mode, then, configure the
units with the following automatic setup procedure.
1. Switch all the units to standby.
2. Press Clear on the handset.
Each unit will display:
Auto
One unit will then be designated as the controller and display:
Con
Connections
All the other units will be configured as non-controllers and
display:
Ncon
The system is now set up and ready to use.
If for any reason the automatic setup does not give the
configuration you want, you can restore the default operation
by selecting a Type or by setting the controller status in
Config as described on page 20.
Connecting to Meridian Digital speakers
1. Connect the phono plug on the end of the M-lead to the
digital output of the 562/V.
4. Connect one of the two DIN plugs on one end of the Mlead to one of the COMMS sockets on the back of 562/V.
Note There are usually two DIN plugs on an M-lead. Take
care to chose the correct one and do not force the plug. The
second plug is used to connect to any 200 Series products in
the range.
Connecting digital recorders; CDR, DAT
or DCC
1. Connect a digital output on the recorder to one of the
digital inputs on 562/V as described on page 33.
2. Use Config to connect that input to one of the source
keys, see page 27.
3. Connect the second digital output of 562/V to a digital
input on the recorder.
34
Connecting analogue tape recorders
1. Connect the analogue output on the recorder to one of the
analogue inputs on 562/V as described on page 30.
2. Connect one of the tape outputs of 562/V to an analogue
input on the recorder.
Connecting video recorders to 562V
1. Connect the analogue output on the recorder to one of the
analogue inputs on 562V as described on page 30.
2. Connect one of the tape outputs of 562V to an analogue
input on the recorder, or via a SCART cable if one is used.
3. Connect the chosen video output of the VCR to one of the
video inputs of 562V. If you are using composite video
choose V1–V6, if you are using S-VHS choose S1 or S2.
4. Connect one of the VCR video outputs of 562V to a
selected video input on the VCR. You can use S-VHS or
composite, this connection does not have to be the same
as the input to the VCR. (But there must be a complete
signal path with input to 562V)
Connecting a video camera to 562V
1. Connect the analogue output on the camera to one of the
analogue inputs on 562V as described on page 30.
2. Connect the chosen video output of the camera to one of
the video inputs of 562V. If you are using composite video
choose V1–V6, if you are using S-VHS choose S1 or S2.

Making recordings
The 562/V is ideally suited to making many types of
recordings, in particular both analogue and digital recorders
can be used at the same time.
General caution for making recordings
As you will know by now, 562/V is a complex and powerful
control unit, there are however a few things you may need to
understand about how it works in order to make the recording
you want.
Recording is made using either:
• the Tape outputs for analogue signals, or
• the digital tape output.
In both cases the signals routed to these outputs are under
control of the Copy key.
Why can there be any problems making
recordings?
The difficulties you may encounter are due to the following:
• 562/V accepts digital and analogue signals
• 562/V has outputs for analogue and digital recorders (e.g.
cassette, VCR, DCC, CDR etc.).
• 562/V has only one analogue to digital converter
• 562/V (as standard) does not have any digital to analogue
converter
35
Always works OK
The following list shows the copy procedures that always work
irrespective of the main listening source (as opposed to the
copy source).
1. the source you want to copy is available in analogue form
either as the primary or extra input, and you want to make
an analogue recording. (See page 26 for setting up extra
inputs).
2. the source you want to copy is available in digital form
either as the primary or extra input, and you want to make
a digital recording. (See page 26 for setting up extra
inputs).
Conditionally works OK
The following list shows the copy procedures that only work in
some circumstances.
1. the source you want to copy is available in analogue form
only, and you want to make a digital recording. This
process only works if either:
• the Copy source is also the main source selected by
the Source key (in effect you are using Copy–Source.
Copy–Source means ‘record what I am listening to’ –
except of course Mute and Volume do not effect the
recording!
• the main listening Source is digital, freeing up the
analogue–digital converter for the Copy process.

to–analogue converter on the digital source to provide an
extra analogue input.
Never works OK
The following list shows the copy procedures that do not work
as expected.
1. the source you want to copy is available in digital form
only, and you want to make an analogue recording.
The standard 562/V does not have any means to convert
digital signals to analogue.
Overcoming copy difficulties to digital
recorders
There is no ready solution to the fact that 562/V only has one
analogue–digital converter. We advise caution when making
digital recordings from analogue sources. The simplest
strategy is to listen to the recording on Source, and use
Copy–Source.
Overcoming copy difficulties to analogue
recorders
To obtain reliable copy functions for digital sources onto
analogue recorders you have the following options:
1. If the digital source (e.g. CD, DCC, MD or Laser disc
player) has both analogue and digital outputs, connect
both. Use the digital connection as the main one and the
analogue as an extra. See page 26 for details on setting
up main and extra inputs.
2. If the digital source does not have both analogue and
digital outputs (e.g. CD transport), use an external digital–
3. If you have several digital-only sources, or the digital
source supports only one output, then connect an external
DAC. The digital signal to the DAC is taken from the digital
tape output of 562/V. Connect the analogue output of the
DAC to the DAC sockets on 562/V. Set the DACT option
in Config as described on page 21. Note: this option is not
available if you have an internal DAC fitted.
4. Upgrade 562/V to have the internal DAC option fitted.
Consult your dealer.
Making video recordings
The 562V is ideally suited to making many types of video
recordings.
Note The VCR input must be connected in the same format
as the source being recorded, so if the source is composite,
the composite VCR output must be connected to an
appropriate input on the recorder.
Recording a TV broadcast
The method you choose to record a TV broadcast will depend
on the connections in your system. The following basic
options exist.
1.
Make the recording in the usual way using an RF feed to
the tuner section of the VCR from an antenna system or
a remodulated RF output from a satellite or cable box..
Connections
2.
If you have a separate TV, satellite or cable tuner and
you want to use their direct video out:
• Connect these sources to the 562V as described on
page 34. Setup the 562V using Config as described on
page 20.
37
• Check that the VCR video outputs and the analogue audio
tape outputs are connected to the VCRs.
Note Both recorders need to be connected in the same
format i.e. composite or S-VHS.
• Make the recording using the Copy function of 562V
using either Copy-Source if you are watching the
programme, or Copy-TV.
Recording a simultaneous broadcast
When recording a simultaneous broadcast, we normally want
to combine in the recording the picture from one source – e.g.
TV with the sound from another – e.g. FM radio.
To make a recording of a simultaneous broadcast, you first
define a new ‘phantom’ source with the right properties.
1. Choose an unused source from the twelve available
logical sources (keys on the remote control).
2. Using Config set it up to use the signals you want; e.g. the
current TV-video and Radio-audio connections. For more
details on Config see page 20.
3. Watch the broadcast by selecting that source.
Using D600, DSP5000 or D6000
speakers with 562/V
Please note, the following systems must be operated in 200
Mode!
• systems using D600
• systems using D6000 with software versions less than
2.0. (To see the version of your D6000s put them into
standby and then press Display on the D6000 handset.
The first number displayed will either be 1.x or 2.x.)
• systems using DSP5000 with software versions less than
2.0. (To see the version of your DSP5000s put them into

considerable user benefits.
Providing both VCRs are connected as described on page 34,
you will be able to copy from one to the other using the Copy
feature of 562V.
D600 does not have a software upgrade, the options are to
use 200 mode or to upgrade the D600 to DSP5000B by
changing the electronics panel.
4. Record the broadcast by using Copy.

Technical Information
Additional technical information
Understanding input sensitivity in a
digital preamplifier
There is no variation of sensitivity for digital inputs. The
consumer SPDIF interface defines full-scale in terms of the
digital word coming in.
In a conventional analogue preamplifier the input sensitivity is
normally quoted as that level required to give rated output
when the volume (i.e. gain) is turned full up. In 562/V this
figure is less important than the maximum input that can be
fed to the preamplifier without distortion. This level is
sometimes given for analogue preamps as the overload level.
For the analogue inputs of 562/V, the input sensitivity you
select in Gain (see page 29) is the voltage at which the
analogue–digital converter will overload. For some sources –
e.g. Radio, Tape or Video this can be very closely defined
and the nominal output of the source will be within 3dB of its
maximum. For other sources – e.g. turntables, the maximum
signal is less well defined and some experimentation may be
beneficial. See the section following on ‘How to get the best
out of LP’.
40
Clipping and overload
Input overload occurs for analogue signals that overdrive the
analogue–digital converter. We have fitted a Level light to the
front panel of 562/V. If you are close to overload on analogue
sources this will flash. The threshold for this light is 3dB below
clipping. Ideally you will use a combination of 562/V input
sensitivity and source output that is as much as possible
consistent with this light never – or only very rarely – flashing.
An obvious exception to the ‘never’ rule would be on
interference signals like ignition noise on a tuner or bad
scratches on a record.
How to get the best out of LP
The turntable source is quite unique in the problems it
presents to getting optimum sound quality. Obviously the
turntable itself must be correctly setup and we recommend
you have your dealer check it from time-to-time.
562/V has several adjustments that affect the sound quality of
turntable sources. Here is a starting checklist.
1.
Is the 562/V installed far enough away from
components which contain mains transformers to
ensure that you get no hum induced?
2.
Is your cartridge Moving-coil or Moving magnet. Ensure
you have the right module fitted.
Pickup cartridges tend to have their output specified at 5cm/s
recorded velocity. Normally the maximum velocity found on
Technical Information
an LP is 25cm/sec at the outside and around 18cm/s in the
inner grooves. 25cm/sec is about the maximum tracking
ability of audiophile MC cartridges. Certain moving-magnet
cartridges can track up to 35cm/sec but there are rarely these
velocities to be found.
On the face of it we could adjust the LP input sensitivity to 5
times the rated output of the cartridge. If we do this then as
expected the overload Level light very rarely illuminates. This
kind of setting gives three benefits:
• The maximum digital level for any recording.
• The lowest noise contribution from the analogue–digital
converter.
• The best loudness match when switching from LP to other
sources.
41
However, under many circumstances you may prefer to set
562/V to a lower sensitivity – i.e. larger number in Gain –
because you prefer the sound overall. The reason is that the
analogue–digital converter has such a wide range compared
to the surface-noise of LPs, that you can allow more
headroom (for very short clicks due to dust etc.) without any
noise penalty. This alternative fitting of the available dynamicrange of the LP signal into the 562/V input ‘window’, can give
better sound overall but at the expense of level matching
between sources.
Tip Start at the 2dB setting.
Setting up AV systems

• C, Chroma information
Setting up an A-V system
Understanding video connections
There are four common methods for transferring video
information; these are listed in decreasing order of potential
performance.
RGB
Separate connections are used for red, green, blue, sync and
audio information. In a consumer system, RGB actually
makes sense in very few circumstances:
• For connection between the PAL, SECAM or NTSC
decoder and the tube or monitor. The functions of tube
and decoder are very rarely separated, but it is done to
separate projectors and ‘pro’ monitors from the ‘receiver’
electronics.
• For connection from a camera source which has RGB
outputs, normally only used for broadcast and some
closed-circuit (CCTV) applications.
• To permit differing standards to be viewed on a TV; e.g.
viewing NTSC material on a PAL only receiver.
S connection
The S or Super-VHS system uses an inappropriate 4-pin miniDIN connector for two video signals known as ‘Y’ and ‘C’. A
Y/C connection uses two 75Ω cables to connect the signals:
• Y, combined luminance, blanking and sync
This connection system originated in S-VHS and other highband recorders like Video-8. The reason for this connection is
that these recorders actually maintain the chroma and
luminance information separately on the tape and it is
considered beneficial to pass them directly to the
PAL/SECAM/NTSC decoder in separate form.
Composite
Composite – strictly called CVBS (chroma, video, blanking,
sync), contains the same information as Y and C, but they are
combined with C riding on Y as an HF modulation. The
modulation frequency is 3.58MHz for NTSC and 4.43MHz for
PAL. This connection is made unbalanced at 75Ω and
normally uses a cinch-phono in consumer applications.
CVBS is a highly efficient system. The quality that results
depends critically on the frequency response and accuracy of
the link as well as on the design of the subsequent separation
circuits.
Modulated RF
Modulated RF signals are equivalent to terrestrial
broadcasting and are used in the ‘normal’ RF output
connection of domestic video units like VCRs.
The modulated RF combines the CVBS signal with a subcarrier that carries the sound signal (4.5MHz FCC, 5.5MHz
Euro-PAL, 6MHz UK PAL). The RF mode is the only one that
carries the sound with the picture. In the UK, Hong Kong and
Setting up AV systems
other licensed countries NICAM digital sound is encoded on a
separate carrier at 6.55MHz.
In quality terms, RF modulation degrades the signal due to
noise, distortion and response amplitude and phase errors.
Video signals in sources
This section reviews how the signal is used in the chain to
help understand the trade-offs involved.
Camera
The source of almost all video information. The signals from a
camera are, or may be in:
1. RGB from the detector
2. Combined into Y and C according to the standard
(PAL/SECAM/NTSC )
3. Composite CVBS
4. Modulated RF
Broadcast
All terrestrial and virtually all satellite broadcasts use RF
modulated CVBS with sound. This is an important point to
note, since the source for domestic VCRs includes broadcast
which is originally a fully-combined CVBS signal.
Receiver
All broadcast receivers perform the following processes from
input to tube:
1. Demodulation of RF into CVBS and sound
2. Separation of CVBS into sync, luminance and chroma
43
3. Decoding of luminance and chroma into RGB
Advanced receivers have switched inputs for RF, CVBS, S
and RGB.
VCR normal
The signal recorded on the tape is in a crude CVBS form and
gives approx. 300 line definition. VCR output is usually RF
and CVBS.
VCR high-band
S-VHS or Video-8 formats. These recorders keep luminance
and chroma separate but only relevant if source was Y/C
such as direct from camera or camcorder. High-band
recorders give approx. 400 line definition and have RF, S and
CVBS outputs.
Laserdisc
The signal encoded on a Laserdisc is pure CVBS – but in
digital form so that there is very little loss from the amplitude
and phase errors that plague other CVBS carriers (like
broadcast or cable).
Some Laserdisc players have S as well as CVBS
connections. It should be realised however that this is not
necessarily a benefit. All that happens is that the CVBS signal
is split into Y/C in the Laserdisc player instead of in the
decoder in the monitor. Which is better will depend on the
models, but given that we are starting with a CVBS signal it is
probably better to use the fully-matched decoder in the
monitor/projector to maintain balance and consistency across
sources.
Setting up AV systems
It may be necessary to use an RGB output from LaserDisc if
the disc is recorded in a different format from your normal TV,
e.g. to view an NTSC disc on a PAL or SECAM TV.
Cable
Cable systems are not really different from terrestrial
broadcast. Cable boxes normally produce an RF output that is
inferior to a good antenna, and may occasionally have CVBS
output.
Distortions in video
Video signals have wide bandwidth, the data requires a 7MHz
bandwidth, but because all these signals are analogue and
because the chroma information is encoded as phase
modulation (CVBS and RF), the signals benefit from much
wider band links. Obviously in broadcast and all storage
media the bandwidth is limited by channels; the best carrier
by far being Laserdisc since its frequency response errors are
exactly predictable and can be corrected. Video distortion is
summarised.
• Amplitude distortion of Y component leads to change of
brightness, contrast and grey-scale relationships.
• Phase distortion of Y component causes picture spatial
distortion
• Amplitude distortion of C component changes colour
saturation.
• Phase distortion of C component changes hue of colour
and in severe cases noticeable spatial separation of
colour and Y information.
44
In a decoder the CVBS signal is split to Y and C. In order to
separate C a narrow-band filter is used. This filter introduces
a delay of around 70µs, a delay line is used in the Y channel
to re-align the signals. The effectiveness with which CVBS
can be separated into a good Y/C combination depends on
the design of these filters and compensators. In the case of
any Y/C connection we can see that hook-up must be made
with high-quality cable, clean connections and the same
transmission characteristic for both cables, otherwise the Y/C
integrity could deteriorate. This is one reason why CVBS with
a good link (like 562V) followed by a good separator can often
be better than the standard S routing found in AV receivers.
If the signal is originally in Y/C format – such as in a camera
or a high-band recorder – then it is not possible to encode
that to CVBS and decode it back without some loss of picture
quality.
Distortions on RF links
RF encoded video signals have the benefit of carrying may
channels in parallel. The predominant difficulties that arise in
this method is cross-modulation between channels and the
results are normally noise and patterning distortions.
Differential gain and phase
On a video link, the noticeable error is differential gain of 10%
and phase of ±5°. Most of this budget is used up in the
broadcast system.
A typical A-V receiver uses switching to route signals. These
switches are not necessarily impedance matched and will
misbehave in a system-dependent way – especially when
Setting up AV systems
45
using connectors that are not 75Ω – like mini-DIN. It is not
uncommon for AV receivers to introduce errors that far
exceed the total budget.
In other countries monitors or televisions tend to be supplied
with composite and S-VHS input connections using phono or
mini-DIN connectors.
By contrast the routing system used in 562V is very well
matched, and incredibly precise – see the specifications on
page 48. Using 562V invariably improves the picture quality
since it has superior drive capability.
An important aspect of making an installation easy to use is to
decide how the monitor will be switched between its inputs,
and between its internal tuner if it is a broadcast receiver.
Hook-up cables
The quality of cables used in video installations is extremely
critical. Ask your dealer for advice. Meridian have a range of
precision 75Ω video cables.
Monitor switching and FNSEL
Whether your screen is a video monitor, broadcast TV
receiver or projector, it will normally have more than one
input. It is not uncommon for a broadcast receiver to have
one or two video inputs in addition to its own tuner section.
These inputs can be:
• RGB
• Composite
• S-VHS or Y/C
European equipment normally comes with one or more
SCART or Peritel connectors. This 21-pin connector is
standardised, and one SCART connector is capable of
accessing audio in/out as well as RGB or Composite input to
the receiver. There is an additional (non-standardised)
working practise to connect S-VHS using SCART.
All receivers with additional video inputs can be switched to
those inputs, usually using front-panel controls or by remote
control. These methods are less satisfactory unless you can
design your system so that 562 actually carries all the video
signals. (Note: this will not usually the case if you plan to use
the internal tuner in the television).
Some sets now on the market use sensing to detect when a
signal is fed to an AV input, they then switch automatically to
that input. This method is ideal for use with 562V providing
you setup ‘Blank’ (or switching to unused inputs in the case of
S-VHS) for sources which have no picture or which use the
monitors internal TV tuner.
Sets using SCART can be controlled properly from the 562V.
The two Function Select FNSEL outputs can be wired to each
of two AV inputs and cause either (F1 or F2) or none (F0) to
be selected, giving seamless control of the video path from
the 562V.
Planning a video installation
There are three main issues to planning the video side of a
562V installation:
• user convenience
• picture quality
Setting up AV systems
• tape copying
Convenience
User convenience primarily means minimising and making
more obvious the number of operations necessary to get the
system to do what you want.
Maximum user convenience arrives when 562V is able to
switch all the video and audio sources with one button on the
remote control or front panel. The audio path is relatively
straightforward. To achieve the same result for video, there
are three options:
1. All video sources through 562V
46
•
562V blanks its outputs when you want the monitor to
use external sources.
3. Some video sources through 562V, SCART
•
video sources can use different formats
•
only some video signals pass through 562V – maybe
not including video level broadcast and cable.
•
the monitor inputs are switched by 562V using
FNSEL.
Picture quality
•
all video sources use the same format (normally
composite)
Contrary to the popularly disseminated view, it is not
automatically better to use an S-VHS connection, for these
reasons:
•
all video signals pass through 562V – including video
format broadcast and cable. This normally means a
video tuner separate from the TV, but a stand-alone
tuner can give a significant quality improvement.
1. The majority of sources providing S connections, generate
them from an original composite source, therefore the
question is whether the decoder in the source product is
better than the decoder in the TV receiver.
•
the monitor is permanently switched to the video
input.
2. Using an S-VHS connection can cause you to unwittingly
route the signal through two PAL/NTSC decoders.
2. Not all video sources through 562V, auto switch
•
video sources can use different formats
•
only some video signals pass through 562V – maybe
not including video level broadcast and cable –
instead the internal tuner of the TV is used.
•
the monitor automatically switches to the live video
input.
3. The split Y/C signal is more fragile and subject to
distortion of transmission from one unit to another than
the composite format which keeps the whole signal
together in its original form.
The only sources that can potentially benefit from an accurate
S connection to the monitor are:
• Camera or camcorder direct,
• MAC or digital TV broadcasts.
Setting up AV systems
• S-VHS recorder but only for recordings made from
Camera or digital broadcasts.
Providing the monitor/projector has a high quality decoder for
PAL/SECAM/NTSC, then it is usually better to keep all the
signals together in their original composite form, and to
maintain the integrity of that signal using professional studio
techniques in the electronics and cable specifications.

Standby point not lit
Check the following:
1. There is AC power connected to the socket on the rear of
the 562/V
2. The power switch on the rear panel of the 562/V is turned
on
If the 562/V will still not illuminate, check any fuses in your
power supply and the fuse in the inlet of the 562/V. If these
are all intact, contact your dealer.
Audible hiss at high volume settings
The input dynamic range of any recordings you have are at
maximum 16 bit. The reason for this is that CD and other
consumer sources use a 16 bit standard. The analogue
sources you have cannot achieve this kind of range. For
comparison, analogue sources are likely to be of the order of:
• FM Radio, 13 bits
• Reel-reel tape, 13 bits
• Cassette tape, 12 bits
• LP, 11 bits.
Note that there may be a difference between the dynamicrange of the source channel when it is operating, and the
noise you hear in standby. For example LP normally has
lower noise when the stylus is not in the groove; similarly tape
50
will be quieter when it is stopped. CD may also be quieter
when it is stopped, producing so-called ‘digital silence’.
The 562/V has a 16 bit capability from input to output on
analogue sources. When the volume is turned up high you
may hear this dither as a hiss when the sources are stopped.
This hiss is lower than the background noise of your
recordings and is of no consequence.
Poor sound quality
Poor sound quality will usually result from one of the following:
• Driving an analogue input too hard. generally this will be
accompanied by a flashing of the Level light on the front
panel. The solution is to adjust the input sensitivity for that
source in Gain. See page 29.
Hum on LP inputs
The turntable input is the most sensitive on the 562/V. It is
fairly common for installations to have problems with hum.
The most common causes are:
• Tone-arm not connected to the technical ground of 562/V
as described on page 30.
• Tone-arm connected to power ground in turntable. This
connection is not appropriate for 562/V since the analogue
input section of 562/V is not connected to its output (which
is connected to the power ground).
• Magnetic pick-up. If you have another piece of equipment
that incorporates a mains transformer too near the
turntable or the left-hand-side of 562/V this may be the
Help
cause of hum – particularly with MC cartridges. Re-orient
the equipment to see if this fixes the problem.
Hum on other inputs
51
Communications not working between
562/V and other Meridian products.
If you have this problem check the connections carefully.
There is no reason for 562/V to produce hum on analogue
inputs other than LP. Check the source equipment. If 562/V
seems to be the cause of hum consult your dealer.
Are you using a mix of 200 and 500 mode units?
‘TV doesn't work’ using 562V
NOTE 562/V is a digital audio and computing device which
has been designed to very high standards of electromagnetic
compatibility.
• Check all video connections.
• Are you using an automatic switching monitor? If so, are
you producing a blank condition to enable the built-in
tuner?
• Are you using FNSEL on a SCART socket? If so, have
you set F0 to enable the built-in tuner?
Poor picture quality
Picture quality may suffer if you do not attend to the following.
Radio interference
FCC WARNING: This equipment generates and can radiate
radio frequency energy and if not installed and used correctly
in accordance with our instructions may cause interference to
radio communications or radio and television reception. It has
been type-tested and complies with the limits set out in
Subpart J, Part 15 of FCC rules for a Class B computing
device. These limits are intended to provide reasonable
protection against such interference in home installations.
Are you using suitable quality cables with good connectors?
Is there a ground-loop created between any of the
components connected to 562V?
Remember that reception of broadcast or cable signals can
be significantly deteriorated by cross-modulation in the RF
domain. It is unwise to attempt to cascade and mix several
video sources (e.g. LaserDisc, VCR etc.) to an antenna
system.
If this equipment does cause or suffer from interference
to/from radio or television reception then the following
measures should be tried:
1. Reorient the receiving aerial (or antenna) or route the
antenna cable of the receiver as far as possible from the
562/V and its cabling.
2. Ensure that the receiver uses well-screened antenna
cable.
3. Relocate the receiver with respect to the 562/V.
Help
4. Connect the receiver and this product to different AC
outlets.
5. If the problem persists contact your dealer.
