Coaxial digital audio inputs
Connect the coaxial digital output cables
of your source devices to these inputs. The
digital inputs can be freely associated to any
analogue audio sources (see menu option
for further reference), but the MDP 500
is supplied set up as above.
If you re-assign any of the digital inputs to
different analogue inputs, record this in the
blank column provided.
8
Optical digital audio inputs
Connect the Optical Digital audio cables to
these inputs. These inputs can also be freely
associated to any analogue audio sources
(see menu option for further reference), but
the MDP 500 is supplied set up as shown in
the table above.
9
Channel inputs
7.1
(left front,
centre, right front, left surround, right
surround, left rear, right rear
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 Rear and Right
Rear channels are provided for future
surround formats (see below). The 7.1
CHANNEL inputs may be used with mono,
stereo, 5.1 channel or 7.1 channel sources.
You can also use these inputs as an “Analogue
Direct” input if you want to bypass the digital
section of the MDP 500. In this case it is not
possible to use the record outputs.
10
Channel outputs
7.1
(left front,
centre, right front, left surround,
right surround, left rear, right rear
and subwoofer)
Connect these outputs to the line inputs
of your power amplifier(s), such as the
Myryad MA 240 and MA 360 two and three
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.
The LEFT REAR (LR) and RIGHT REAR (RR)
outputs are for compatibility with future
surround formats. These outputs carry the
analogue signal that is fed to the LEFT REAR
and RIGHT REAR 7.1 CHANNEL INPUTS
to allow the MDP 500 to be used with
an external 7.1 channel analogue source
connected to the 7.1 channel inputs. It will
be possible in the future to fit the MDP 500
with a hardware upgrade which will allow
it to decode 7.1 channel digital sources.
At the time of writing this manual there is
no 7.1 channel source material (e.g. DVDs)
on the market.
11
Record outputs
The REC outputs carry the signal from which-
ever 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.
12
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 MON output. The On Screen Display
(OSD) information is present on this output.
You can also use the COMPOSITE VIDEO
MON output even if no composite video
source is connected. The selected S-Video
signal is down-mixed to this output and can
be used for monitoring.
13
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
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.
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
My-Link input/output
When the MDP 500 is used in a system
with other Myryad M-Series products, all
may be joined together via the My-Link.
TheMY-LINK output of the MDP 500 should
be connected to the MY-LINK input of the
next product and its MY-LINK output
connected to the MY-LINK input of the next
and so on in “daisy-chain” fashion. This
inter-linking provides two main benefits.
firstly, when the MDP 500 is switched out of
(or into) STANDBY, either using the front
panel switch or the remote control, all the
other linked Myryad products will switch
out of (or into) STANDBY at the same time.
Secondly, only one linked product with its
own Infra Red receiver (e.g. a CD player, but
not a Power Amplifier) needs to be “in line
of sight” of the remote handset. The My-Link
will carry the remote command from any
IR receiver to all the other products that are
linked together.
Finally, the MY-LINK may be used to interface
with various proprietary multi-room control
systems. Contact your Myryad dealer or
Myryad Systems Ltd. for details or visit the
Myryad website at www.myryad.co.uk.

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 MDP 500 is switched
out of STANDBY and turned off again
immediately when the MDP 500 is switched
into STANDBY again. The TRIGGER outputs
may also be programmed to be activated
under other conditions (see menu section,
page 13).
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.

Standby switch
When the preamplifier is plugged into a live
wall socket and the POWER switch is turned
ON, it will power up in "standby" mode
and the LED (Light Emitting Diode) in the
STANDBY button will glow red. In this mode
the internal circuitry of the MDP 500 is
powered up but inactive.
When the STANDBY button is pressed 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 and
the LINE outputs will be muted for a few
seconds. During this delay period the blue
LED in the STANDBY button will flash to
indicate this mute condition. When switched
out of STANDBY for the first time the AUX 2
input will be selected by default.
When the STANDBY button is pressed again
the preamplifier will be returned to standby
mode and the LED in the STANDBY button
will glow red again. Always switch the MDP
500 to STANDBY before switching the
POWER off at the rear.
CAUTION: WHEN IN STANDBY MODE THE
INTERNAL CIRCUITRY OF THE MDP
500
IS
STILL LIVE, SO ALL SAFETY PRECAUTIONS
MUST BE FOLLOWED.

Display
Located behind this window is a high quality
blue Vacuum Fluorescent Display (VFD)
which indicates the operating condition of
the MDP 500 – including the selected input,
operating mode and volume setting. Also
behind this window is the Infra-Red detector
which receives the commands sent to the
MDP 500 from the remote handset.
3
Volume control
The volume control adjusts the sound level
of the signal fed to the 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). When first switched on the
volume sets automatically to –20, which is
a typical listening level. If the volume is set
below –20 then this will be remembered
when the MDP 500 is switched into STANDBY
and re-instated when it is switched on again.
However, 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.

Source select
5
and
6
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 output
sockets for recording. The display shows
which input has been selected. The SOURCE
5
and
6
buttons scroll through all the
sources except TAPE. TAPE and 7.1 CH
inputs are selected by the TAPE MONITOR
and 7.1 CHANNEL input buttons.
When any of these inputs is selected, the
MDP 500 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.
The signal source selected by the SOURCE
5
and
6
buttons will be fed to the TAPE REC
output sockets, irrespective of whether the
TAPE button is engaged or not. Thus, if you
have a "three-head" tape deck that permits
off-tape monitoring you can use the TAPE
button to switch back and forth between the
source signal and the off-tape signal, to check
its quality, whilst the recording is in progress.
Pressing the TAPE button does not affect
the operating mode of the MDP 500, which
continues to be the mode applying to the
input source currently selected.
NOTE: IF THE TAPE BUTTON IS ENGAGED WITH
NO SIGNAL SOURCE CONNECTED TO THE TAPE
PLAY, OR WITH NO TAPE RUNNING, THEN YOU
WILL HEAR ONLY SILENCE.
6
Mode button
The MODE button is used to cycle through
the available music modes that are be
available when a 2-channel analogue or
digital source is selected. These are: STEREO,
MONO, PRO LOGIC and MUSIC and they
are described in the following table. When a
multi-channel digital source is selected the
MDP 500 will automatically use the most
appropriate multi-channel processing.
