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.
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.
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.
Using 562 Starting off with 562/V 8 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.
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.
Using 562 10 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.
Using 562 11 Information reviewed in standby To move the sound to the left 1. Press and hold Display. 1. Press Left The display will show the current balance, e.g. The display will show the version number of the microcontroller software, e.g.: ← 1 1.1 The number indicates the dBs advantage given to the left. To move the balance back again Advanced operation using the Remote Control Balance control 1.

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.
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.
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.
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.

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.
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.
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.
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.
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.
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.
Connections 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.
Connections 36 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.
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.
Connections If you have DSP5000s or D6000s with software version 2.0 or greater, then move to the following section, ‘500 mode digital speakers’ and follow the instructions for D5000. 200 Mode digital speakers Note If you operate the speakers in 200 mode, then all Meridian 500 Series products must be set to 200 mode. See the instructions that came with each product. In general it will be necessary to select a Type in the same way as 562/V and if in doubt choose Type 2. Do the following: 1.
Connections 2. 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. 3. Setup the speakers according to the manual, selecting a Type that expects a preamplifier (like 562/V). • D6000 version 2.x start with Type 1. • DSP5000 version 2.x start with Type 1. 4. Set the 562/V to Type 1 (see the instructions on page 16). 5. Set other 500 components to Type 1. Note There are usually two DIN plugs on an M-lead.
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.
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.
Setting up AV systems 42 • 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.
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.
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.
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.
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.
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.
