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 6
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:

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.
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 7
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
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 left-
hand-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.

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.

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.
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.
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

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.
To increase the volume
1. press ,, the right-hand volume key on the 562/V or
press the top red key on the Remote
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:
CD65
65. The volume level displayed will count up or down and ranges from 1 to 99. Each step is 1dB.
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.
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
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.
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:
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
Tape Copy
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.
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

3. While pressing the Off key on the 562/V front panel, switch the power on again. The display will read:
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 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.
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 14
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
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 15
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.
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!
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 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.
205 or 605
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 16
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.
Making changes to an existing setup
Config and Gain are configuration editing modes, they do not reset on entry. Type however performs a full reset of all parameters.
To make any changes to your custom configuration:
1. Change to Config or Gain – whichever is appropriate,
2. make the changes you want,
3. change back to Normal.
Customising using Type
Type is a mode used specifically to setup 562/V into one of nine factory-preset configurations. Type resets the following for all nine Types.
