INTRODUCTION

The Myryad MXD6000 Digital PreamplifierProcessor has been designed to offer a combination of high quality audio and video performance with simple yet elegant styling. The MXD6000 forms the heart of a high-end home cinema and audio system and should be used with high quality power amplifiers such as the Myryad MXA 2150, MXA 3150, MXA5150 and MXA 7150 two, three, five and seven channel power amplifiers.

The MXD6000 can decode a wide variety of discrete surround material including Dolby Digital1, Dolby Digital Surround EX1, DTS2, DTS-ES Matrix and Discrete2, DTS Neo:6 2 and a proprietary mode “Surround 6.1” – together with the ability to down-mix any source to mono or stereo. It also functions as a high quality stereo preamplifier and any stereo analogue source can be sampled at 48kHz for further digital processing, or at 96kHz for the best sound quality without any further processing. The 7.1 channel input is equipped with comprehensive volume control facilities and ensures that the MXD6000 will remain compatible with new multi-channel formats as they appear – as well as providing a “pure analogue” bypass input for audiophile analogue sources such as DVD-Audio and SACD.

The MXD6000 also has several music modes that may be used to enhance a normal two channel stereo signal. These modes include Dolby Pro Logic1, Dolby Pro Logic II 1, DTS Neo:6 2, and two “music” modes: Natural, and Party.

The MXD6000 can accept up to six digital input sources, eight line-level input sources, plus a tape loop and two additional record outputs. It has six composite and S-Video inputs, composite and S-Video monitor outputs, composite and S-video record outputs and an S-Video monitor output without OSD (On Screen Display) for highest quality video performance. In addition there are Zone B stereo analogue audio and composite video outputs which can convey a separately selected programme to a second room.

The MXD6000 automatically senses the type of the incoming digital audio signal and selects the best mode for that signal. The user can also bypass the digital section of the MXD6000 and connect, for example, a high quality stereo source to the Left and Right channels of the 7.1 channel input.

The MXD6000 is supplied with a comprehensive learning remote control handset which is pre-programmed to control the MXD6000 and other Myryad products. In addition to the MXD6000 it can also control up to 7 other products using a combination of the pre-programmed Myryad codes and either recalling one of its internally stored code sets, or learning the codes from a product’s own remote.

Options for system integration are provided by Smart My-Link input/output connectors to interface with other Myryad products, by the three 12VDC trigger outputs to control external equipment and by communication with a PC or home automation system via the RS 232 interface.

INSTALLATION AND SAFETY NOTES

This preamplifier generates a modest amount of heat and thus requires ventilation. Do not place it on a rug or other soft surface into which it could sink. Do not allow papers or cloth to obstruct the ventilation grille in the top cover. The MXD6000 should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided.

CAUTION: TO PREVENT A FIRE OR SHOCK HAZARD, DO NOT PERMIT THIS PRODUCT TO BECOME WET. IF LIQUID IS ACCIDENTALLY SPILLED ON IT, IMMEDIATELY SHUT OFF ITS POWER AT THE WALL SOCKET AND UNPLUG THE AC POWER CORD. ALLOW SUFFICIENT TIME FOR COMPLETE EVAPORATION TO OCCUR BEFORE OPERATING THE UNIT AGAIN. IF THE LIQUID IS ANYTHING BUT WATER AND/OR ALCOHOL, A QUALIFIED SERVICE TECHNICIAN SHOULD EXAMINE THE UNIT BEFORE IT IS USED AGAIN

Do not remove the cover, or attempt to modify or repair the preamplifier yourself. Refer all servicing to a qualified technician.

REAR PANEL CONNECTIONS

CAUTION:

BEFORE MAKING ANY CONNECTIONS TO YOUR MXD6000 MAKE SURE THAT IT IS SWITCHED OFF AT THE REAR AND THAT ITS POWER CORD IS DISCONNECTED (EITHER AT THE WALL SOCKET OR AT THE REAR OF THE MXD6000). ALL EQUIPMENT BEING CONNECTED TO THE MXD6000, EITHER DIRECTLY OR INDIRECTLY, MUST ALSO BE SWITCHED OFF BEFORE ANY CONNECTIONS ARE MADE.

Failure to follow these precautions may result in excessive ground currents flowing briefly into the MXD6000 which can permanently damage internal connections and will invalidate your Warranty.

1. Power inlet

Before making any connection, check that the mains voltage or range of voltages printed on the rear panel includes your local mains supply voltage.

Plug the female (socket) end of the power cord into the power inlet on the rear of the preamplifier. Plug the male (plug) end of the cord into a "live" wall socket or a suitable heavy duty extension cable. Connect the MXD6000 only to a grounded wall socket.

UK version only:

The mains plug is supplied fitted with a fuse. It should only be replaced with a fuse of the same rating which complies with BS1362.

2. Power switch

Press one side of this rocker switch (the side nearer the edge of the rear panel) to switch the preamplifier ON and the other (towards the audio connectors) to switch it OFF. When the POWER switch is in the OFF position all power is disconnected from the preamplifier. In this condition the MXD6000 cannot be powered up from the

front panel or the remote control.

When the POWER switch is in the ON position (and the power cord correctly inserted and plugged into a live wall socket) the MXD6000 will power up in standby mode (see FRONT PANEL CONTROLS, STANDBY on page 5).

It is recommended that the POWER switch is turned OFF if the MXD6000 is not going to be used for an extended period of time.

CAUTION: ALWAYS SWITCH THE MXD6000 TO STANDBY BEFORE SWITCHING THE POWER OFF, TO AVOID LOUD NOISES THROUGH THE LOUDSPEAKERS.

3. Analogue stereo inputs

Connect the analogue audio output cables of the appropriate devices to these sockets. Always connect these inputs, even though you may intend to listen only via the digital inputs (for example in the case of a CD or DVD player). This ensures that a signal will always be present at the record outputs.

The signal from ANALOGUE stereo inputs is fed to an A-D converter that converts the signal to digital format. The signal can then be processed using Dolby Pro Logic, Pro Logic II, DTS Neo:6 or other modes. The signal is then fed to D-A converters and thence to the 7.1 channel line outputs. The selected signal is also fed to the three ANALOGUE record outputs.

[A-D = Analogue to Digital; D-A = Digital to Analogue]

4. Tape input/output

These connectors are suited to any type of tape recorder, including high-quality "3- head" types which allow you to monitor the signal off the tape whilst it is being recorded. Connect a stereo cable from the TAPE REC output sockets of the preamp to the LINE IN or RECORD IN sockets on your tape deck. Connect a second stereo cable from the TAPE PLAY input sockets of the preamp to the LINE OUT or PLAY OUT sockets on your tape deck.

The TAPE loop allows you to monitor the quality of an Analogue recording whilst the recording is taking place. It can also be

used for connecting devices such as equalizers into the analogue signal path. Note: if an equalizer is used it must be bypassed when listening to Pro Logic sources to ensure correct decoding.

Any ANALOGUE stereo source selected for listening on the MXD6000 will automatically be fed to the TAPE REC output sockets for recording. Recordings cannot be made from a source connected to the digital inputs or the 7.1-channel input

5. Composite video inputs

Connect the composite video output cables from your video sources to these inputs. Be careful to use inputs with the same name for the composite video, S-Video and analogue audio cables from a single source (e.g. cables from a VCR should go to the VCR S-VIDEO, VCR COMPOSITE VIDEO and VCR ANALOGUE inputs).

The composite video signal is selected from these sources, and the signal is fed out from the COMPOSITE VIDEO record (REC) and monitor (MON) outputs. On Screen Display information is added to the monitor (MON) output.

6. Composite video record and monitor outputs

Connect the composite video input of your VCR to the COMPOSITE VIDEO “REC” output. Connect the composite video input of your display device (TV) to the COMPOSITE VIDEO “M-OSD” monitor output. The On Screen Display (OSD) information is present on this output only. You can also use the

“M-OSD” output even if no composite video source is connected. The selected S-Video signal is down-mixed to this output and so can be used for monitoring. The OSD can be switched off on the “M-OSD” output using the Display setup menu. Alternatively you can connect your display device to the “M-HQ” high-quality output. This by-passes the OSD circuitry so you cannot view the OSD – and

it will not give any down-mixed output from S-Video sources – but it will deliver slightly better video quality.

7. S-Video inputs

Connect the S-Video output cables from your video sources to these inputs. Be careful to use inputs with the same name for the composite video, S-Video and analogue audio cables from a single source.

S-Video signals are of higher quality than composite video signals. Therefore if your source devices have S-Video outputs it is recommended that you use them, together with the S-Video inputs on your display. S- Video inputs are also automatically down-

mixed to feed the composite video M-OSD output for displays which do not have S-Video inputs.

8. S-Video record, monitor and high quality monitor outputs

Connect the S-Video input of your VCR to the S-VIDEO REC output. Connect the S- Video input of your display device (TV) to the S-VIDEO MON output. The On Screen Display information is displayed in this output, but may be switched off using the Display setup menu. The MON HQ output displays the selected source without routing

it through the On Screen Display circuit thus giving the best possible video quality. If a composite video source is selected, the S-Video outputs will carry only a black-and- white video signal.

9. Coaxial digital audio inputs

Connect the coaxial digital output cables of your source devices to these inputs. The digital inputs can be freely assigned to any analogue audio or audio-video sources (see Source setup menu for further reference), but the MXD6000 is supplied set up as follows:

Digital audio input	Assigned to input	Re-assigned to input
COAX 1	AUX 1
COAX 2	AUX 2
COAX 3	SAT
COAX 4	TUNER
OPTICAL 1	CD
OPTICAL 2	DVD

If you re-assign any of the digital inputs to different analogue inputs, record this in the blank column provided. You may assign a digital input to more than one analogue input if desired.

Note: The “SPDIF” digital interface is very sensitive to the quality of connection when using 96kHz sample rate sources.

Always use a high quality digital coax interconnect if 24bit/96kHz operation is desired.

10. Optical digital audio inputs

Connect the Optical Digital audio cables to these inputs. These inputs can also be freely assigned to any analogue audio or audio-video sources, but the MXD6000 is supplied set up as shown in the table above.

Note: The “SPDIF” digital interface is very sensitive to the quality of connection when using 96kHz sample rate sources.

Always use a high quality optical interconnect if 24bit/96kHz operation is desired.

11. 7.1 Channel inputs (Left Front, Centre, Right Front, Left Surround, Right Surround, Left Back, Right Back and Subwoofer)

Connect the audio line outputs from any multi-channel analogue source such as a DVD-Audio player or Super Audio CD (SACD) player to these inputs using up to eight interconnect cables (or four stereo cables) as necessary. The Left Back and Right Back channels are provided for future surround formats. The 7.1 CHANNEL inputs may be used with any mono, stereo, 5.1 channel or 7.1 channel source.

You may use these inputs as an “Analogue Direct” input if you want to bypass the digital section of the MXD6000 (use Left Front and Right Front for a stereo source). The record outputs are not active when the 7.1 channel input is selected.

12 7.1 Channel outputs (Left Front, Centre, Right Front, Left Surround, Right Surround, Left Back, Right Back and Subwoofer)

Connect these outputs to the line inputs of your power amplifier(s), such as the Myryad MXA 2150, MXA 3150, MXA 5150 and MXA7150 two, three, five and seven channel power amplifiers. The SUB output will normally be fed to the low-level Line Input of an active subwoofer. Alternatively it may feed a separate power amplifier and passive subwoofer.

If the setup has only one rear speaker, its amplifier should be connected to the Left Back output.

13. Record 1 & 2 outputs

The REC outputs carry the signal from whichever ANALOGUE stereo source device is currently selected (except the source connected to the TAPE PLAY input or the 7.1 CHANNEL input). These outputs may be connected to the inputs of any recording device, or the signal may be used in a multi-room set-up to feed power amplifiers in other rooms.

14. Digital output

Connect the optical input of your digital recording device to the DIGITAL output. The selected digital source is fed to this output in optical digital format.

15. Zone B audio and composite video outputs

These connectors carry the stereo analogue audio and composite video signals selected for Zone B. The MXD6000 allows you to feed separate audio or audiovideo programmes to two different areas, or zones, in your home. To feed video and audio to a second zone (Zone B), connect a composite video cable (with RCA plugs) to the “ZONE” composite video output and a pair of audio cables to the “ZONE OUT” audio connectors. The “ZONE” audio

output is always stereo (unless you are playing a monophonic source). See “Zone B operation” section on page 13 for full details of how the second Zone operates.

16. Smart My-Link® input/output

When the MXD6000 is used in a system with other Myryad M-Series products, all may be joined together via the Smart MyLink®

The output of the MXD6000 should be connected to the Smart My-Link® input of the next product and its Smart My-Link® output connected to the Smart My-Link® input of the next and so on in “daisy-chain” fashion. This inter-linking provides three main benefits.

Firstly, when the MXD6000 is switched out of (or into) STANDBY, either using the front panel ellipse or the remote control, all the other linked Myryad products will switch out of (or into) STANDBY at the same time. Note: there is a short processing delay (about 1.5 seconds) between the MXD6000 switching into STANDBY and the Smart My-Link® control pulse switching the other linked units into STANDBY.

Secondly, only one linked product with its own Infra Red receiver (e.g. a Myryad CD player, but not a Power Amplifier) needs to be “in line of sight” of the remote handset. The Smart My-Link® will carry the remote command from any IR receiver to all the other products that are linked together.

Finally, the Smart My-Link® may be used to interface with various proprietary multiroom control systems. Contact your Myryad dealer or Myryad Systems Ltd. for details or visit the Myryad website at www.myryad.co.uk.

17. RS 232 control interface

You can connect the MXD6000 to a home automation system through this interface. Contact your Myryad dealer or Myryad Systems Ltd. for details or visit the Myryad website at www.myryad.co.uk.

18. Remote trigger outputs – 1, 2 and 3

You can connect the DC trigger inputs of any audio or other equipment to these TRIGGER outputs. The TRIGGER outputs may be activated when the MXD6000 is switched out of STANDBY and turned off again immediately when the MXD6000 is switched into STANDBY again. The TRIGGER outputs may be programmed to be activated under other conditions (see Trigger setup menu section, page 11).

OPERATING YOUR SYSTEM

FRONT PANEL

CONTROLS

1. Standby

When the preamplifier is plugged into a live wall socket and the POWER switch is turned ON, the display will read “Myryad MXD6000 Initialising” after about 3 seconds. This display will remain for around 5 seconds before the display goes blank and the LED (Light Emitting Diode) in the display will glow red. The MXD6000 is now in standby mode, with its internal circuitry powered up but inactive.

When the STANDBY ellipse is touched the preamplifier circuitry will be activated and the last used INPUT and last used MODE automatically selected. The LED in the STANDBY button will change to blue, the display will briefly read “Myryad MXD6000 Initialising” and the LINE outputs will be muted for a few seconds. During this delay period the blue LED in the display will flash to indicate this mute condition.

When the STANDBY button is touched again the preamplifier will be returned to standby mode, the display will briefly read “Myryad MXD6000 Shutting down” and the LED in the display will glow red again.

CAUTION: always switch the MXD6000 to STANDBY before switching the POWER off at the rear to avoid loud noises through the loudspeakers.

CAUTION: WHEN IN STANDBY MODE

THE INTERNAL CIRCUITRY OF THE MXD6000 IS STILL LIVE, SO ALL SAFETY PRECAUTIONS MUST BE FOLLOWED.

The TRIGGER outputs deliver +12V DC with a maximum current of about 40mA from each of the three trigger outputs.

CAUTION: THE TRIGGERS SHOULD ONLY BE CONNECTED OR DISCONNECTED WHEN THE POWER SWITCH IS OFF, OR THE UNIT IS DISCONNECTED FROM MAINS POWER.

2. Display

Located behind this window is a high quality blue Vacuum Fluorescent Display (VFD) which indicates the operating condition of the MXD6000 – including the selected input, operating mode and volume setting. Also behind this window (and located to the left of the standby ellipse) is the Infra-Red detector which receives the commands sent to the MXD6000 from the remote handset.

3. Volume control

The volume control adjusts the sound level of the signal fed to the 7.1 CHANNEL line outputs. It does not affect the signals fed to the TAPE REC sockets so it can safely be adjusted whilst making a recording.

The volume setting is indicated in the bottom right of the VF display, for example “vol: -35”. The display indicates the preamplifier gain in dB (decibels) referenced to THX standard gain (-2.5dB). When first switched on the volume is set automatically to –20, which is a typical listening level. If the volume is set below – 20 this will be remembered when the MXD6000 is switched into STANDBY and re-instated when it is switched on again. If the unit is switched to STANDBY with a volume setting higher than –20, it will be reset to –20 when switched on again to protect against excessive sound levels.

The volume control range is from -90dB to +15dB when all channel level adjustments (e.g. in the Speaker level or Audio setup menus) are set to zero or negative values. If any of the trims is set to a positive figure, the maximum volume setting is reduced by the same amount to prevent inadvertent digital overload.

When the volume level is being changed (using the front panel control or the remote), there may be small “ticking” sounds at each volume step. These will be more noticeable at higher volume settings. These noises are quite normal and have no effect upon the sound quality once the volume control has been set.

4. Source select • and ‚

These buttons scroll up or down through the inputs to select the source (audio or audio-video) that is fed to the main outputs for listening and viewing. The same signal will also be fed to the TAPE REC and REC 1 & 2 output sockets for recording. The display shows which input has been selected.

The SOURCE buttons scroll through all the inputs except TAPE. TAPE and 7.1 CH inputs are selected by the TAPE MONITOR and 7.1 CHANNEL buttons – see below.

When an input is selected, the MXD6000 will automatically switch to the operating MODE last used with that input, or to the correct digital decoding if an active digital source is assigned to the input.

5. Tape Monitor

When you press the TAPE MONITOR button you can hear the output signal from a recording device connected to the TAPE PLAY sockets on the rear panel. This is a "toggle" function switch: you press it once to engage and press again to disengage. The TAPE MONITOR input also disengages if a new source is selected either from the remote or front panel. Pressing the TAPE button has no effect on the other source select buttons.
