introduction

The Myryad MDP 500 Digital Preamplifier­Processor has been designed to offer a
combination of high quality audio and video
performance with simple yet elegant styling.
The MDP 500 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 MA 240 and MA 360
two and three channel power amplifiers.

The MDP 500 decodes Dolby Digital
and Dolby Pro Logic1(MPEG decoding is
an optional extra which may be retro-fitted).
It also functions as a high quality stereo
preamplifier. The 7.1 channel input is
equipped with comprehensive volume
control facilities and ensures that the MDP
500 will remain compatible with new multi­channel formats as they appear. The MDP
500 also has several music modes that may
be used to enhance a normal stereo signal.

The MDP 500 accepts 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 n S-Video monitor output
without OSD (On Screen Display) for
highest quality video performance.

The MDP 500 has two main modes of
operation. In the normal operation mode
the MDP 500 automatically senses the type
of the incoming signal and selects the best
mode for that signal. The user can override
the automatic selection and select different
post-processing modes for the incoming
signals. These modes feature a mono down­mix, stereo, Dolby Pro Logic and four
music modes: Natural, Concert, Club and
Party. The user can bypass the digital section
of the MDP 500, if desired, and connect,
for example, a high quality stereo source
to the Left and Right channels of the 7.1
channel input.

The MDP 500 is supplied with a compre­hensive learning remote control handset
which is pre-programmed to control the MDP
500 and all other Myryad products. It can
also control up to 6 other products, either by
recalling one of its internally stored code sets,
or by learning the codes of the product’s
own remote.

Options for system integration are provided
by 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. The MDP 500 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 PREAMPLIFIER AGAIN.
IF THE LIQUID IS ANYTHING BUT WATER AND
/OR ALCOHOL,THE PREAMPLIFIER SHOULD
BE EXAMINED BY A QUALIFIED SERVICE
TECHNICIAN 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

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
MDP 500 only to a grounded wall socket.

UK version only: The mains plug is supplied
fitted with a 5A fuse. It should only be
replaced with a fuse of the same rating (5A)
which complies with BS1362.

2 Power switch

Press the bottom of this rocker switch to
switch the preamplifier ON and the top to
switch it OFF. When the POWER switch is in
the OFF position all power is disconnected
from the preamplifier. In this condition the
MDP 500 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 MDP 500 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 MDP 500 is not going to be
used for an extended period of time. Always
switch the MDP 500 to STANDBY before
switching the POWER off.

3 Analogue inputs

Connect the analogue 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 audio inputs is
fed to an A-D converter that converts the
signal to digital format. The signal can then
be Dolby Pro Logic decoded or post-processed
with music modes. Then the signal is fed to
D-A converters and thence to the 7.1 Channel
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.

Any ANALOGUE stereo source selected for
listening on the MDP 500 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 inputs.

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 signals, 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 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 down­mixed to feed the composite video MON
OSD output for displays which do not have
S-Video inputs.
