Introduction 5 Introduction Congratulations on choosing the DSP5000C – the world’s first DSP centre-channel loudspeaker. We are confident that it will give a quality to your music that is unprecedented, and bring years of listening pleasure. This manual will enable you to get the most from it. The DSP5000C is a sophisticated product. You should therefore read all the supplied documentation before fully installing the DSP5000C, particularly if you intend to customise its functions.
Description 6 DSP5000C description You will find it simpler to understand how the DSP5000C works if you consider it as a combination of the following components: • digital preamplifier, to select and control up to two digital sources directly, and to provide fixed and switched digital output for other speakers • digital audio processor, whose functions include decoding as well as error detection and correction • digital signal-processor, dealing with tone controls, digital crossover, dynamic bass control,
Description 7 Control The DSP5000C is operated either by commands received from the Meridian System Remote (available from your dealer), or by commands received through the communications cables of a Meridian installation (for example, from the front panel of a 565, 562 or 501). The remote control provides enough keys to allow you to drive a Meridian installation via a DSP5000C, and this is the method to be preferred.
Using DSP5000C 8 Unpacking the DSP5000C In the pack you should find: • 1 DSP5000C digital active speaker complete with grilles • 4 self-adhesive rubber feet to protect furniture • DSP5000C user manual (this manual) • Getting going sheet • 1 power cord suitable for your territory • composite system cable M5 (phono + DIN to phono + DIN, 8 metres) • composite system cable S5 (phono + DIN to phono + DIN, 6 metres) • hex wrench (3mm), for drive units If any of these items is missing, please contact your dealer
Using DSP5000C 9 Installing your DSP5000C General precautions Before carrying out any installation, you should ensure that the DSP5000C 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 DSP5000C, or to any other component in your system, when the AC power supply is switched on.
Using DSP5000C 10 Calibration and Test are intended only for use by the factory or by service engineers. Connections For details of making all connections, see Connecting DSP5000C, on page 40 You will need to make four types of connection to the DSP5000C: • digital audio • communications • master–slave • AC power Digital audio connections will need to be made to other components in your system.
Using DSP5000C 11 As a Left – Right or a Surround pair The locations chosen for a pair of DSP5000Cs are crucial to getting the best possible acoustic result. For two-channel stereo, the two speakers should ideally be equidistant from the main listening position, and the same distance apart. Since it has a horizontal format, the DSP5000C can be mounted on a strong shelf or on a suitable stand – about which your dealer can advise.
Using DSP5000C 12 Starting off with DSP5000C First install the DSP5000C, using the information in the Getting going sheet. When it has been used for a while, you may wish to change the setup in order to fine-tune it to your requirements. To achieve this, refer to the setup section of this manual, beginning on page 28. 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 DSP5000C 13 Standby The entire Meridian system is designed to be left connected to AC power at all times. • The Standby state ensures that the components operate at maximum efficiency from the moment when you start listening. It is perfectly safe and consumes a negligible amount of power. However, when you are not going to use your system for some time (when you are going on holiday, for instance), we would advise you to disconnect it from the AC power supply.
Using DSP5000C 14 Basic operation of DSP5000C Note DSP5000C is factory set for the most common installation, one using the full features of a Meridian 500-Series CD player and 565 Digital Surround Processor. For a Centre, we call this a Type 6 installation. For more details, see Appendix 1 on page 52. Selecting sources To switch from CD to another input, say Radio: 1. Press Radio In Type 1, this will select RD on a Meridian 562/5.
Using DSP5000C 15 Display DSP5000C displays information to help you operate it.
Using DSP5000C 16 1 Here 1 is the number of the track currently playing on the disc. If the disc includes significant index points, the display will be like this: 3.4 3.4 here means track 3, index point 4. In theory, with the right disc, we could see displays of track and index up to 99.99. Index point 1 is never displayed.
Using DSP5000C 17 Mute To mute the sound: 1. Press Mute The display now shows that the sound is ‘attenuated’: Att. To demute (restore the sound level): 1. Press Mute The Mute key toggles between mute and demute. The system may also be demuted by selecting another source, or adjusting the volume. The menu system The DSP5000C offers a number of user choices which are normally accessed less frequently than, for example, source and volume.
Using DSP5000C 18 perhaps to compensate for a non-central listening position or a highly asymmetric layout. This is certainly not the case. Stereo sound is dependent upon time differences between the signals from the channels. To get the best out of a normal stereo system, you should be in the correct position in relation to the speakers.
Using DSP5000C 19 Tilt control Tilt controls are combination controls that slope the frequency response of the system slowly over the frequency range to make the sound brighter or dimmer. They are less crude than conventional tone controls. The responses of the tilt control in DSP5000C are shown in Appendix 4 on page 58. To review the tilt setting: 1. Press the w or the e menu key until the tilt display shows. The master display will momentarily show t. 0.
Using DSP5000C 20 in 565). This has been done specifically to allow you to tonally match the centre to the left and right main pair which may have a different sound. Bass control The bass control allows you to adjust the bass response in the room. The responses of the bass control in DSP5000C are shown in Appendix 4 on page 58. To adjust the bass: 1. Press the w or e menu key until the bass cursor display shows. The master display will momentarily show b. 0.
Using DSP5000C 21 Phase explained The phase function controls the absolute phase of the digital conversion and is used to compensate for recordings which are out of phase. Experiment with the sound of the setting. If you are not sure, set it to positive phase. Axis To adjust the axis: 1. Press the w or e menu key until the axis cursor display shows. The master display will momentarily show A. 0 This allows you to ask the DSP5000C what its axis setting is without changing it. To change the axis: 1.
Using DSP5000C 22 • tilt to 0.0 • balance to middle You cannot store settings in Normal mode. See page 39. Recalling settings The settings stored in the DSP5000C can be recalled at any time. When the display is normal (i.e. not a tone cursor): 1. Press Store The DSP5000C will respond with rEc. Tip You can now compare the stored settings with the standard ones. Use the Clear key to restore a flat response, then Store to recall the stored settings.
Operation 23 Controlling a Meridian CD player Use of handset to control CD You are advised to operate the system with the MSR. Playing a disc On the MSR, the following keys operate the Meridian CD: To start a disc 1. Press Play To stop the disc 1. Press Stop To make the disc pause 1. Press Pause The Pause indication on the Meridian CD will light up. If the DSP5000C master was displaying track or time information, it will display PSE To start it again (‘unpause’) 1.
Operation 24 To select a track by number, press the appropriate number key or keys. For example, to select track 6 1. Press 6 The DSP5000C will respond with the display – 6 To engage this selection, press Play or wait for a short time. To select track 15 1. Press 1 followed by 5 The DSP5000C will show – 15 Again, press Play or wait for a short time. If you select a track that does not exist on the disc, the DSP5000C will show an error message: Err.
Operation C. 25 6 Press Play to action a programmed sequence. Use with 504, 204 or 604 FM tuner When a 204 or 604 is the system tuner, it can be controlled by the MSR but only if the DSP5000Cs are set up in 200 mode (for example by selecting Type 2. A 504 tuner can operate in both 200 and 500 modes. Select the tuner with Radio. The display will show rd. ## where ## is the volume number.
Operation 26 Operation summary On the remote control KEY FUNCTION Off CD, LP etc.
Customising DSP5000C: overview 27 Customising DSP5000C: an overview DSP5000C is a very sophisticated device, with a number of options which allow you to set up exactly the system you need. Programming of DSP5000Cs should take place after you have set up the speakers and sorted out most of the connections. If you first get the speakers working with some kind of digital input (e.g. a CD player), and with the programming provided (e.g.
Customising DSP5000C: how to 28 How to customise DSP5000C DSP5000C needs no customising to become operational. Once you have your system established, you may wish to review the customising options by reading Customising DSP5000C: an overview (page 27). Customising: general procedure DSP5000C has seven operating modes (not to be confused with Types): • Standby • Normal • Type • Config • Setup • Calibrate • Test Standby and Normal are the everyday operating modes.
Customising DSP5000C: how to 29 master/slave, sources and preamplifiers without losing any other settings you may have made. In this mode, the DSP5000C is 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 affect the way in which DSP5000C responds to certain keys.
Customising using Config 30 Customising using Type Type is a mode used specifically to restore the entire memory (except the calibration memory) of DSP5000C to one of eight factory-preset configurations. For all eight Types, Type resets the following: • phase to positive • axis to –1 • balance to central (L 0) • tilt to 0.0 • bass to 0.0 • centre position to 1 • speaker to left master or centre master (Type 6) Depending on the Type selected, the other options are set as follows.
Customising using Config 31 Choosing centre, left or right If you have Typed the speaker with a 6, then the ‘Cen.y’ option is enabled. This tells the speaker that there is a centre in the system and enables the option to make the DSP5000C into a centre. If you Typed the speaker with a number other than 6 then the ‘Cen.n’ option is selected and you do not get the ‘centre’ choice in this section. To change the speaker from centre to left or right, or vice versa: 1.
Customising using Config 32 • source menus Inside Config you can move between them at will. To go to 1. root: press Clear 2. system: press Off 3. source: press a source key – e.g. CD Note In Config, the speaker is silenced. How to use Config 1. Switch off the master DSP5000C, using the power switch on the back, and wait for 3 seconds 2. While pressing the 0 key on the remote control, switch the power on again.
Customising using Config 33 The display looks like this: Cd ?? The first letters tell you which options are available to you, as follows: • 500 tells you that this system operates in Meridian 500-Series mode. All controllable Meridian products must be 500 compatible. Also use this if the DSP5000C is the only controllable preamplifier connected (i.e. the source keys on the MSR will only select between the two inputs of the DSP5000C). • Pr.
Customising using Config 34 System protocols Multiroom systems have protocols which allow you to define the extent to which any room can interfere with the main system. You can choose to have the DSP5000C ignore the Standby state of the associated preamplifier, looking after its own Standby independently. To select this mode while in the system menu: 1. Press Fn - Record The display should indicate 'preamplifier off' like this: ?? P. Toggle this choice with Fn - Record. Setting the Volume mode 1.
Customising using Config 35 Source menus The source menus are used to change what happens when you press a key on the MSR (i.e. what the DSP5000C then displays, and which input it selects). These parameters are already set up by the Type chosen as the start Type, but they can be adjusted using the following menus. Source menu 1 options Source menu 1 controls the display that will be seen on the DSP5000C when a key on the MSR is pressed in normal use.
Customising using Config 36 Source menu 2 options Source menu 2 is used to define which DSP5000C input will be selected for any given source key on the MSR. You get to source menu 2 by using the menu e key while in source menu 1. The display will be like this: cd d1 The first part of the display tells you which key on the MSR you are setting up. The second part of the display tells you which input on the back panel of the master DSP5000C will be selected when this key is pressed.
Customising using Config 37 Source menu 4 options Source menu 4 is used only in 500 mode, and to define the Comms address of the source product. You get to source menu 4 by using the menu e key while in source menu 1. The display will be like this: cd 1A The first part of the display tells you which key on the MSR you are setting up. The second part of the display tells you the address. Normally you should leave this set to ‘1A’ unless advised otherwise by your dealer or Meridian technical support.
Customising using Setup 38 In Normal operation, the settings you have made will be retained and cannot be changed without going back to Setup. Boundary controls The frequency balance of a loudspeaker is changed, particularly in the low-frequency regions, according to its proximity to walls or boundaries. The DSP5000C is designed as a stand mounting system, so the floor boundary is not fixed. It may also be used pulled out from the wall on stands or shelf mounted.
Customising using Setup 39 Centre-channel options The following two adjustments will appear on the master if the ‘Cen.y’ option is selected in Config or if the speaker has been set to Type 6. It appears on the master – whether or not it is a centre. A DSP5000C (or DSP5000) which is configured as a centre responds to these menu settings. Using the centre boundary control The centre boundary control is like the system boundary control, but it can be operated independently of other speakers in the system.
Customising using Setup 40 2. Press Store Limitations of storing Tilt and bass settings are stored by each source independently. Phase, axis and boundary settings are stored for all sources, and the last setting stored is that used for all sources.
Connecting DSP5000C 41 Routing cables Do not route the DSP5000C cables any nearer to TV or radio antenna cables than is necessary. Try to keep any excess cable lengths coiled up, as far from any tuner or television receiver as possible. Where possible, use a dedicated AC power outlet for each DSP5000C. In any case, try not to use the same outlet group for any tuner or TV. DSP5000C is a digital audio product, and its use involves distributing digital audio signals.
Connecting DSP5000C 42 Digital audio connections Note A digital audio connection will be made into the D1 input if you use the M5- and S5-leads supplied as directed in the section starting on page 43. Digital connections are made to the master DSP5000C: • directly from the digital outputs of up to two sources such as CD, DAT, DCC, MD, or the Meridian 604 digital FM tuner • from the digital output of an analogue-to-digital converter such as the Meridian 607.
Connecting DSP5000C 43 Communications connections Communications connections are only made to other Meridian equipment. In general, you can follow the instructions given for the other equipment, and view DSP5000C as a DSP5000, D600 or D6000 for communication purposes. The following sections describe the major points. If you have a Meridian 500-Series only system For example; 500 or 506 CD, 562 controller, 504 FM tuner 1.
Connecting DSP5000C 44 If you are using a Meridian 201 or 603 and a Meridian 200- or 600-Series CD player Unless you have an older M-lead (as opposed to M5 lead) you will need to obtain an SP5 adapter. An M-lead has two DIN plugs at one end and this is the end to connect to the preamplifier. The SP5 adapter allows an M5lead to connect to 200-Series products. 1. Connect the phono plug at the far end of the M5-lead (from the master) to the digital output of the CD player 2.
Connecting DSP5000C 45 If you are mixing Meridian 200- or 600-Series with 500-Series components 1. Connect the digital and analogue audio as described in the previous sections. 2. Locate the DIN plug at the source end of the M5-Lead. Connect it to one of the sockets COMMS on the rear of a 500-Series unit. 3. Connect the 500-Series communications together as described earlier and in the 500 User Guide(s). 4.

If the software in your 201 is earlier than 201.7, your dealer will be able to obtain an up-to-date EPROM and fit it. Operating code can always be updated. 3. Make sure that the whole system is set up in either 200 mode or in 500 mode. Note All Meridian products must be in the same mode.
Help 50 Radio interference Note DSP5000C is designed to comply with all relevant international standards concerning local-oscillator re-radiation. Note DSP5000C is a digital audio and computing device which has been designed to very high standards of electromagnetic compatibility. FCC WARNING: This equipment generates and can radiate radio frequency energy, and if not installed and used correctly in accordance with our instructions may interfere with radio communications or radio and television reception.
Help 51 Outside the UK, contact the importing agent for the territory. A list of Meridian agents abroad is available from the above address. No responsibility can be accepted for the DSP5000C while it is in transit to the factory or an agent, and customers are therefore advised to insure the unit. In the USA and Canada, contact Meridian America Inc.
Appendix 52 Appendix 1 DSP5000C types Type 1 setup, Meridian 500 series system using 562 The Meridian 562 allows simple control and routing of analogue and digital sources. All connections from sources are made to 562 which then sends a single digital feed to the DSP5000Cs. Type 1 sets the DSP5000C as a left master, so you will need to make the other a right slave, or adjust left/right on both speakers.
Appendix 53 Type 2 setup, Meridian CD as preamp (via 607), 204 connected The Meridian compact disc player range includes players with built-in preamplifiers, such as the 207 and the 208. To use the analogue inputs of these units, it is necessary to put a 607 (or similar) A/D converter between the fixed output of the preamp section and the D2 input of the DSP5000C. It is possible to control one of the previously mentioned CD preamp combinations and a Meridian FM tuner using Type 1.
Appendix 54 Type 4 setup, 601 preamp or 201 or 603 as preamp via 607, Meridian CD and 204, CD with direct connection In this Type, the CD player is directly connected to D1, and all other sources are mediated through an external control unit or preamplifier. The output of an analogue preamplifier (201 or 603) will have to be converted to a digital signal for DSP5000C. A Meridian 607 converter is recommended. The Meridian 601 preamplifier incorporates an analogue–to–digital converter for analogue sources.
Appendix 55 Type 5 setup, Meridian 500 system not using 562 The CD is connected directly to D1, all other sources are routed directly or via an A/D converter to D2. Type 5 sets the DSP5000C as a left master, so you will need to make the other a right slave, or adjust left/right on both speakers.
