• Condensation can occur in the device due to rapid, drastic changes in ambient temperature—when the device is moved from one
location to another, or air conditioning is turned on or off, for example. Using the device while condensation is present can cause dam-
age. If there is reason to believe that condensation might have occurred, leave the device for several hours without turning on the
power until the condensation has completely dried out.
• When turning on the AC power in your audio system, always turn on the power amplifier LAST, to avoid speaker damage. When turn-
ing the power off, the power amplifier should be turned off FIRST for the same reason.
• Always turn the power off when the device is not in use.
Saving data
This device has a built-in backup battery that maintains data in internal memory even when the device’s power is switched off. The backup
battery will eventually become depleted, however, and when that happens the contents of the internal memory will be lost.* To prevent loss
of data be sure to replace the backup battery before it becomes fully depleted. If the backup battery runs low, alert number “12.” will appear
in the [PRESET] display either while the unit is starting up. If this occurs, do not turn off the power, but immediately save the data to a com-
puter or other external storage device, and then have qualified Yamaha service personnel replace the backup battery. The average life of
the internal backup battery is approximately five years, depending on operating conditions.
* Data items maintained in the internal memory by the backup battery are as follows:
• Contents of the current preset and the preset number
• Parameters specific to the unit (e.g., configuration data)
• Current parameters for peripheral devices within the same system
• Event log
Data items other than those described above are stored in memory that does not require backup power, and will be retained even if the
backup battery fails.

This device is guaranteed to operate at an ambient temperature
of 0 to 40 °C. If this device is mounted in an EIA rack together
with other devices, heat from the various devices may cause the
temperature inside the rack to rise, rendering this device unable
to perform to its full potential. To ensure that heat does not
accumulate inside this device, please ensure that the following
conditions are met when rack-mounting it.
• If you plan to mount this device together with devices that
tend to generate heat, such as power amps other than XMV
series products, allow 1U or more of vacant space between
this device and other devices. Also attach ventilation panels
in this space or leave them open to ensure sufficient ventila-
tion.
• Leave the back of the rack open, and allow at least 10 cm of
space between the rack and the wall or ceiling to ensure suf-
ficient ventilation. If the back of the rack cannot be left open,
provide forced air cooling for the rack, for example by
installing a commercially available fan kit. If you install a

This Euroblock connector allows input and output of control
signals via GPI (General Purpose Interface).
The MRX7-D provides sixteen ports of analog/digital input,
one port of digital input, and eight ports of output. The [IN]-
1–15 terminals detect voltage changes from 0V to 5V. The
[IN]-16 terminal alone supports +24V input; voltages in the
range of 2.5–24V are detected as High, and voltages below
2.5V are detected as Low. The [OUT]-1–8 terminals are
open collector outputs; they will change between open or
closed (Ground). The +5VDC terminals has an output volt-
age of 5V. Use the included Euroblock plugs to make con-
nections (see “Euroblock plug connection” on page 13 for
details).
For details on connections and usage, refer to “Connecting
via the [GPI] connector” on page 20.

o [YDIF] connectors
These connectors are used to make a ring connection with
the devices that comprise the MTX/MRX system, allowing
digital audio signals to be transmitted and received. Use
CAT5e or better Ethernet STP cables (shielded twisted pair
cables) that have all eight pins connected in a straight con-
nection. The maximum cable length between devices is 30
meters, and you can connect up to eight devices that are
equipped with the [YDIF] connectors. For details, refer to
the MTX-MRX Editor User’s Manual.
!0 POWER IN +24V DC
Support for this connector is planned for the future.
!1 Dante [PRIMARY]/[SECONDARY] connectors
This is an RJ45 connector used to connect the unit to a com-
puter or a Dante device such as the XMV4280-D via an
Ethernet cable (CAT5e or better is recommended).
If DIP switch 4 on the rear panel is set upward (to DAISY
CHAIN), audio signals coming into one of these connectors
will be output from the other. Refer to “Daisy chain net-
work” in the “About connections” section (see page 15) for
more information on daisy chain connections.
If DIP switch 4 on the rear panel is set downward (to
REDUNDANT), the Dante [PRIMARY] connector will be
used for primary connection, and the Dante [SECONDARY]
connector will be used for secondary (backup) connection. If
the unit is unable to transmit signals through the Dante [PRI-
MARY] connector for some reason (e.g., due to damage or
accidental removal of the cable, or a failed network switch),
the Dante [SECONDARY] connector will automatically take
over the connection. Refer to “About redundant networks” in
the “About connections” section (see page 16) for more
information on redundant networks.
The connected computer is used mainly with the dedicated
“MTX-MRX Editor” application program for the purpose of
setting up or controlling the MTX/MRX system.
!2 [ST IN] connectors
These are unbalanced RCA phono jacks for inputting analog
audio signals from a CD player or other device.
!3 SLOT
This slot allows a separately sold Mini-YGDAI card to be
installed.
!4 [INPUT]/[OUTPUT] connectors
These are balanced input/output connectors for analog audio
input and output. Connect line level devices or microphones
to the [INPUT] connectors, and line level devices to the
[OUTPUT] connectors. The [INPUT] connectors provide
head amps, and can also provide +48V phantom power.
MRX Designer is used to specify the gain of the internal
head amps and to turn the phantom power on/off.
Use the included Euroblock plugs to make connections (see
“Euroblock plug connection” on page 13 for details).
NOTE
Using a Mini-YGDAI card for an external word clock may
cause noise in system configurations with multiple YDIF
connections. In such cases, we recommend using a differ-
ent word clock source, such as Dante or YDIF.
NOTE
• Since Dante-compatible equipment made by Yamaha
such as the MRX7-D contains a built-in network switch,
the number of hops will be two or more. For this reason,
the 0.15 msec Latency setting in Dante Controller will be
grayed-out and unavailable.
• Use STP (shielded twisted pair) cable to prevent electro-
magnetic interference.
NOTE
Adjusting the internal head amp gain between +17 dB and
+18 dB will internally turn PAD on/off. Noise may occur if
there is an impedance difference between the Hot and Cold
of a device connected to the [INPUT] connectors while
phantom power is being used.

Euroblock plug connection
Use the included Euroblock plugs when making connections
to the [INPUT]/[OUTPUT] connectors and [GPI] connector.
1. Loosen the terminal screws.
2. Insert cables.
3. Securely tighten the terminal screws.
Pull the cables (not too strongly) to confirm that they are
securely connected.
4. For the Euroblock plugs (3-pin) of the
[INPUT]/[OUTPUT] connectors, use the
included cable ties to fasten the cable to the
tab.
Cable preparation
• Use stranded wire for Euroblock connections, and
strip the wire as shown in the illustration. With a
Euroblock connection, the stranded wire may be
prone to breakage because of metal fatigue due to
the weight of the cable or due to vibration. Cables
connected to the [INPUT]/[OUTPUT] connectors
should be fastened to the tab of the Euroblock plug
(3-pin) using the included cable ties (see illustration
at right). When rack-mounting the device, use a lac-
ing bar when possible to bundle and secure the
cable.
• If cables will be frequently connected and discon-
nected, as in the case of a portable system, we rec-
ommend that you use ferrules with insulation
sleeves. Use a ferrule whose conductor portion has
an external diameter of 1.6 mm or less (1.3 mm or
less for the [GPI] connector) and a length of approx-
imately 7 mm (approximately 5 mm for the [GPI]
connector) such as the AI 0,5 - 6 WH made by the
Phoenix Contact corporation.

About Dante
This product features Dante technology as a protocol to transmit audio signals. Dante is a network pro-
tocol developed by Audinate. It is designed to deliver multi-channel audio signals at various sampling
and bit rates, as well as device control signals over a Giga-bit Ethernet (GbE) network. Dante also offers
the following benefits:
• It transmits up to 512 in/512 out, for a total 1024 channels (in theory) of audio over a GbE network. (The MRX7-D
features 64 in/64 out with a 24/32-bit resolution.)
• Dante uses high accuracy network synchronization standards to achieve sample-accurate playback with extremely low
latency and jitter. Four types of latency are offered by the MRX7-D: 0.25 msec, 0.5 msec, 1.0 msec, and 5.0 msec.
• Dante supports resilient redundant connections against unexpected network problems via primary and secondary cir-
cuits.
Visit the Audinate website for more details on Dante.
http://www.audinate.com/
Additional information on Dante is also posted on the Yamaha Pro Audio website:
http://www.yamahaproaudio.com/
There are two ways to connect the MRX7-D to a Dante net-
work.
Daisy chain network
A daisy chain is a wiring scheme in which multiple devices
are connected together in sequence. In this way, networking
is simple and requires no network switches.
This connection method is suitable for a simple system with
a small number of devices.
However, if a large number of devices are connected, the
latency value must be increased. Also, if a connection is bro-
ken in a daisy chain network, the signal flow is interrupted at
that point and no signal will be transferred beyond that point.
Star network
In a star network, each device is connected to a central hub.
Using a GbE-compatible network switch enables you to con-
figure a wide-band, large-scale network. We recommend a
network switch that features various functions to control and
monitor the network (such as Qos, the ability to assign prior-
ity to data flows — e.g., clock synchronization or audio
transmission on certain data circuits.)
With this topology, it is common to configure a redundant
network so that an unexpected network problem will not
affect any audio or otherwise stable communications.
About connections
NOTE
Please do not use the EEE function (*) of network switches in a
Dante network.
Although power management should be negotiated automati-
cally in switches that support EEE, some switches do not per-
form the negotiation properly. This may cause EEE to be
enabled in Dante networks when it is not appropriate, resulting
in poor synchronization performance and occasional dropouts.
Therefore we strongly recommend that:
• If you use managed switches, ensure that they allow EEE to
be disabled. Make sure that EEE is disabled on all ports
used for real-time Dante traffic.
• If you use unmanaged switches, make sure to not use net-
work switches that support the EEE function, since EEE
operation cannot be disabled in these switches.
* EEE (Energy Efficient Ethernet) is a technology that reduces switch
power consumption during periods of low network traffic. It is also
known as Green Ethernet and IEEE802.3az.
NOTE
The computer that’s running MTX-MRX Editor must be con-
nected to the unused Dante [PRIMARY] connector or Dante
[SECONDARY] connector on the MRX7-D. For details on
connections, refer to “MRX Setup Manual.”

About redundant networks
A redundant network consists of two circuits, a primary cir-
cuit and a secondary circuit. Normally, the network operates
on the primary circuit. However, if the primary connection is
broken, the secondary circuit will automatically take over
audio communications. Therefore, using a redundant net-
work with a star topology would increase resiliency against
unexpected network problems relative to a daisy chain net-
work.
About Dante Controller
Dante Controller is a software application that allows config-
uration and audio routing of Dante networks. Use Dante
Controller if you need to make connections and settings for
devices not supported by MTX-MRX Editor, or if you need
to specify complex signal routings on the Dante network.
More information is posted on the following website.
http://www.yamahaproaudio.com/
To run Dante Controller, a computer must feature a GbE-
compatible Ethernet connector.
Refer to the Dante Controller owner’s manual for details on
Dante Controller.
NOTE
The computer that’s running MTX-MRX Editor must be con-
nected to the [PRIMARY] connector of the MRX7-D. For
details on connections, refer to “MRX Setup Manual.”

actually install and connect the equipment.
1. Prepare a computer in which to install MTX-
MRX Editor.
2. Install MTX-MRX Editor in your computer.
For details on installation, refer to “MRX Setup Manual.”
3. If you want to play back music or other audio
files from the MRX7-D itself, prepare an SD
memory card.
Copy the audio files to your SD memory card. For details on
SD memory card handling, refer to “Using the MRX7-D to
play audio files saved on an SD memory card” (page 21).
4. Start up MTX-MRX Editor.
For details on installing and using MTX-MRX Editor, refer
to “MRX Setup Manual” and “MTX-MRX Editor User’s
Manual.”
5. Set up the entire MTX/MRX system as directed
by the wizard.
Make settings such as the number of connected MTX/MRX/
XMV/Exi8/EXo8/DCP devices, and the UNIT ID and YDIF
mode (Cascade mode or Distribution mode) for each device.
For details on YDIF, refer to “Features” (page 8), and “o
[YDIF] connectors” in “Controls and Connectors” (page 12).
Print out the schematic diagram shown at the end of the wiz-
ard, and use it when you make the actual connections and
settings.
6. The audio signal flow in the MRX7-D and the
principal parameters to be set are as follows.
Make the settings in the order shown.
For details on each item, refer to “MTX-MRX Editor User’s
Manual” and “MRX Designer User’s Manual.”
7. Make DCP settings.
Assign the parameters of the MRX7-D to the switches and
knobs of the connected DCP units. Here you can also spec-
ify the brightness of the DCP’s LEDs. For details on how to
make DCP settings, refer to “MTX-MRX Editor User’s
Manual.”
8. As necessary, make settings for devices
other than the MRX7-D.
For details, refer to “MRX Setup Manual.”
9. Specify and store a preset.
You can use presets to change the volume of zones and the
audio source to play (e.g., SD memory card or CD player)
in a single action. To prevent problems such as a sudden
increase in volume when the MRX7-D is operated, we rec-
ommend that you store the preset with the output level low-
ered to “-infinity (
).” For details on presets and how to
recall them, refer to “Recalling (switching) presets” on
page 19, and “MTX-MRX Editor User’s Manual.”

mitted to all devices, automatically updating their internal
clocks.
You can also update the date and time settings on all devices
connected to the same network by transmitting the computer’s
date and time settings from the “Clock” dialog box in MTX-
MRX Editor.
For more information on operation, refer to “MTX-MRX Editor
User’s Manual.”
The scheduler can switch presets or play music and sound
effects from the SD memory card at the date and time you spec-
ify. Each such setting is called an “event.”
Event settings are made in the “Scheduler” dialog box of MTX-
MRX Editor. For details on operation, refer to “MTX-MRX
Editor User’s Manual.”
< Example 1 >
Switching background music and playback area
according to the time of day
In commercial facilities that switch background music and play-
back areas at different times of the day, you can switch the type
of music and the playback area according to the time of day.
< Example 2 >
Switching the playback time according to the day
of the week
In commercial facilities that switch the time period of music
depending on the day of the week, you can specify the music
pattern and playback times according to the day of the week and
the hours of operation.
• Monday–Friday
• Saturday
• Sunday
You can also play seasonal music, or specify exceptions such as
stopping playback on days when the facility is not operating.
Recalling (switching) presets
NOTE
• If you leave the device for 30 seconds with the [PRE-
SET] display flashing, it will revert to the previous pre-
set number.
• If a control panel such as a DCP series unit is con-
nected, you’ll be able to easily switch presets.

Various Procedures
MRX7-D Owner’s Manual
20
GPI (General Purpose Interface) devices can be connected to
the rear-panel [GPI] connectors. GPI allows a variety of control
signals to be exchanged with external controllers or other
devices.
The MRX7-D provides 16 input ports and 8 output ports.
• The +5VDC terminals have an output voltage of 5V. The
maximum current draw is 100 mA total for the two termi-
nals. If you are using a switch/variable resistor and an LED/
relay simultaneously, connect one terminal to the switch/
variable resistor and the other terminal to the LED/relay.
• The [IN]-1–15 terminals detect voltage changes from 0V to
5V. The [IN]-16 terminal alone supports +24V input; volt-
ages in the range of 2.5–24V are detected as High, and volt-
ages below 2.5V are detected as Low.
• The [OUT]-1–8 terminals are open collector outputs; they
will change between open or closed (Ground). The maxi-
mum voltage that can be applied is +12V. The maximum
current draw is 75 mA per port.
The GPI controller parameters are assigned via the MTX-MRX
Editor application.
Euroblock plugs (16-pin) are used for connections to the [GPI]
connector. For details, refer to “Euroblock plug connection” on
page 13.
• Connection examples using the [GPI IN] con-
nector
• Connection examples using the [GPI OUT]
connector
Connecting via the [GPI] connector
NOTE
By making input/output channel settings in MTX-MRX Editor,
you can recall presets or edit parameters on an external GPI
device or send signals to it. For details, refer to the “MTX-MRX
Editor User’s Manual.”
Example: Controlling the MRX7-D from a switch box
Example: Controlling the MRX7-D with a 10k ohm
linear taper potentiometer.
Example: Lighting LED indicators on external
devices from the MRX7-D
Example: Lighting an LED by switching an exter-
nal device’s relay from the MRX7-D
NOTE
For the method of adjusting the detection range of the input
voltage at the [GPI] connector (calibration), refer to the “MTX-
MRX Editor User’s Manual.”
