Thank you for your purchase of the Yamaha XMV4280 or XMV4140 power amplifier. Please read

through this manual carefully before beginning use, so that you will be able to take full advantage of

your power amplifier’s superlative features and enjoy trouble-free operation for years to come.

After you have read the manual, keep it in a safe place for reference when needed.

NOTE

• When there are differences in the specifications of the XMV4280 and the XMV4140, this manual will use curly brackets { } to
enclose information that applies only to the XMV4140.
(Example: 280W {140W}).

• Unless otherwise specified, illustrations are taken from the XMV4280.

Features Related manuals and software

The XMV is a multi-channel power amplifier with the follow­ing features.

• Both high-impedance and low-impedance connec­tions are supported

Both high-impedance connections to 70V/100V lines and
4Ω/8Ω low-impedance connections are supported. A rear
panel DIP switch allows this setting to be specified for every
two channels.

• Newly-developed “Double Power mode”

The newly-developed “Double Power mode” doubles the
amplifier output of each channel when low-impedance con­nections are used.

* The number of available channels will be halved.

•Settings can be made via application software

Although settings such as mute on/off and attenuator values
can be edited from the panel of the amplifier itself, you can
use an MTX series matrix processor and computer to edit the
settings of multiple XMV units.

• Support for the newly-developed “YDIF” digital
audio transmission format

This allows up to 16 channels of audio and word clock to be
transmitted and received via an Ethernet cable.
This model can receive four channels of audio signals via
YDIF.

•High efficiency

The newly-developed output circuits allows high efficiency.

You can easily configure a complete sound system featuring the
XMV by connecting it to MTX series matrix processors or to
MTX Editor system configuration software. The owner’s man­ual for the MTX and for MTX Editor, and MTX Editor itself
(subsequently referred to as “the editor”) can be downloaded

Precautions for Rack Mounting

This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius. When mounting the unit with
other XMV unit(s) or other device(s) in an EIA standard equipment rack, internal temperatures can exceed the specified upper
limit, resulting in impaired performance or failure. When rack mounting the unit, always observe the following requirements to
avoid heat buildup:

• When mounting the unit in a rack with devices such as power amplifiers that generate a significant amount of heat, leave
more than 1U of space between the XMV and other equipment. Also either leave the open spaces uncovered or install
appropriate ventilating panels to minimize the possibility of heat buildup.

• To ensure sufficient airflow, leave the rear of the rack open and position it at least 10 centimeters from walls or other sur­faces. If the rear of the rack can’t be left open, install a commercially available fan or similar ventilating option to secure suf­ficient airflow. If you’ve installed a fan kit, there may be cases in which closing the rear of the rack will produce a greater
cooling effect. Refer to the rack and/or fan unit manual for details.

will light green. Setting the switch to the downward position
turns the power off. If the switch is in the upward position
and the [POWER] indicator is blinking, the unit is in standby
mode.

CAUTION

• To ensure that high-volume noise is not output from
the speakers, power-on the equipment starting with
the audio sources, then the mixer and processors
(such as the MTX), and finally the amplifiers. Reverse
this order when turning the system off.

• Rapidly turning the power switch ON and OFF in suc­cession can cause the unit to malfunction. After turn­ing the power switch OFF, wait for about 5 seconds
before turning it ON again.

• If you modified parameter settings, do not turn the
power switch OFF for at least one second. Otherwise,
the changes to the settings may be lost.

w [PROTECTION] indicators A/B/C/D

When the protection system is active, the indicator will light
orange. If the audio output is muted, turn off the power and
wait for the XMV to cool before turning the power on again.
The protection circuit will operate in the following situa­tions.



If the amplifier overheats and the output lim­iter operates

The speaker output will be attenuated if the heat sink of
the amplifier section exceeds 80°C (80%), and will be
muted if the heat sink exceeds 90°C (90%). The [PRO­TECTION] indicator will light at 80°C (80%) or higher.



If the power supply overheats and shuts-down

The fan will rotate at high speed if the power supply sec­tion exceeds 90°C, and the analog circuits will shut down
if it exceeds 100°C.
The [PROTECTION] indicator will light at 100°C or
higher.

 When overcurrent is detected

If for any reason the impedance falls below rated, the
speaker output is muted to prevent overcurrent; muting
will be cancelled after approximately one second. If over­current is detected after muting is cancelled, the output
will be muted again.



If DC output is detected

The power supply section will be shut down.

If excessive total current or maximum current



is detected

The output signal will be compressed.

e [LIMIT] indicators A/B/C/D

CAUTION

Steps earlier than “Turning the power on” must be per­formed with the power off. If you perform these steps with
the power on, the settings might not be applied, or you
might be subject to electrical shock if you touch the con­nectors.

 Rack-mounting the unit

Refer to “Precautions for Rack Mounting” (page 7), and
mount the XMV in your rack.

 Checking the device setup DIP switch set-

tings

Make sure that all of the rear panel’s device setup DIP
switches are in the upward position.

 Connecting the analog inputs (Euroblock)

Connect the analog outputs of your mixer or other device to
the analog input connectors of the XMV.
You must use the supplied Euroblock plugs with tabs.
If these have been lost, please contact your Yamaha dealer.

Cable preparation

• To prepare the cable for attachment to a Euroblock
connector, strip the wire as shown in the illustration
using stranded wire to make connections. With a
Euroblock connection, stranded wires may be prone
to breakage because of metal fatigue due to the
weight of the cable or due to vibration. Bundle the
cables and the Euroblock tabs using the supplied
cable ties (page 14). When rackmounting your
equipment, use a lacing bar when possible to bun­dle and fasten the cables.

• If cables will be frequently connected and discon­nected, as in the case of a portable installation, we
recommend that you use ferrules with insulation
sleeves. Use a ferrule whose conductor portion has
an external diameter of 1.6 mm or less, and a length
of approximately 7 mm (such as the AI0,5-6WH
made by the Phoenix Contact corporation).

For details, refer to “High-impedance and Low-impedance
Connections” (page 25).

The explanation of the settings is divided into the following
sections.

 When using low impedance connections (page

14)

 When using low impedance connections with

Double Power mode (page 15)

 When using high impedance connections

(page 15)

Since these settings can be made independently for channels
A/B and channels C/D, you can use more than one of the
above methods

NOTE

Trim any excess part of the cable tie as necessary.

5. Insert the Euroblock plug into the Analog

shown below, and tighten the screw. Be sure that the bare
wire does not touch the chassis.

15mm*

NOTE

• If the [SPEAKERS] DIP switch 4 is in the lowered posi­tion (Double Power mode), even if you do connect a
cable, audio will not be output from channel D.

• If the [SPEAKERS] DIP switch 8 is in the lowered posi­tion (Double Power mode), even if you do connect a
cable, audio will not be output from channel B.

• Ensure that tension is not applied to the speaker cable.

• Connect the cables so that the amplifier’s “+” and “-”
symbols match those of the speaker. If they are
reversed, the phase will be inverted.

TIPS

Since a large amount of current can flow in a speaker
cable, a magnetic field will be generated. If sensitive cir­cuits such as a microphone input cable or a microphone
amp are located near a speaker cable, electromagnetic
induction may produce noise in the input cable or circuit.
Input cables and devices that contain sensitive circuits
should be kept at a distance from speaker cables; we
also recommend that you fasten the cables in place.

 Connecting the power cord

Connect the included power cord to the [AC IN] connector
on the rear panel. First connect the AC power cord to the
socket on this unit, then plug it into an appropriate AC power
outlet.

CAUTION

You must turn off the power before connecting the
power cord.

Setup

 Turning the power on

Use the front panel power switch to turn the power on.

CAUTION

Before you turn the power on, make sure that audio
signals are not being input to the analog input connec­tors. If audio signals are being input, excessive input
will be applied to the speakers when the power is
turned on, possibly damaging the speaker system or
damaging your hearing by high-volume sound. If there
is a problem with the speakers or the wiring, the pro­tection circuit will operate immediately when the power
is turned on. Check whether there might be a problem
with the wiring.

 Enabling analog input

Using the front panel, enable analog input as follows.

1. While holding down the [FUNCTION] but­ton, turn the encoder to make the display
indicate “SRC.”

The control mode will change to “Analog/digital input
selection.”

2. Take your fing er off the [FUNCTION] button,
and turn the encoder to make the display
indicate “ANA.”

Input from the analog input connectors will be enabled.

NOTE

If a certain period of time elapses without any operation
being performed, the unit will be placed in Attenuation
setting operating mode.

 Making high pass filter (HPF) settings

If the unit is set for low impedance connections, the HPF
will be OFF. If the unit is set for high impedance connec­tions, the 80 Hz HPF will be enabled.
If you want to change this setting, proceed as follows.

1. While holding down the [FUNCTION] but­ton, turn the encoder to make the display
indicate “HPF.”

The control mode will change to “HPF.”

2. Press the [SELECT] button of the channel
for which you want to make HPF settings.

The [SELECT] indicator of the channel whose HPF you
are setting will light.

3. Turn the encoder to select the desired HPF
setting.

The available HPF settings are OFF / 40 Hz / 80 Hz.

NOTE

• In order to protect the amplifier, the HPF cannot be turned
OFF if high impedance connections are used.

• If you’re using a sub-woofer with high-impedance connec­tions, we recommend that you change the HPF setting to
40 Hz.

• If you’re using a full-range speaker with high-impedance
connections, the amplifier’s protection circuit may operate
if the HPF is set to other than 80 Hz. We recommend that
you use the 80 Hz setting.

• If a certain period of time elapses without any operation
being performed, the unit will be placed in Attenuation set­ting operating mode.

XMV4280/XMV4140 Owner’s Manual

Setup

 Checking the wiring

Here we’ll explain how to change the attenuation settings
and switch muting on/off, which you will need to do when
checking the wiring.
Before you check the wiring, we recommend that you set the
attenuator of all channels to the lowest setting (-99 dB) to
prevent speaker damage.
To check the wiring, you’ll need to be outputting an audio
signal from the mixer or other device that’s connected to the
analog input connectors.

NOTE

If the speakers are remotely located and you are unable to
check the signal output easily, changing the [SIGNAL] indi­cator setting to “output” will allow you to check whether cur­rent is flowing to the speakers. For details on switching the
indicator setting, refer to “List of Front Panel Operations”
(page 20).

 Changing the attenuator setting

Here’s how to change the attenuator setting.

1. While holding down the [FUNCTION] but­ton, turn the encoder to make the display
indicate “ATT.”

2. Press the [SELECT] button of the channel
whose setting you want to adjust.

The [SELECT] indicator of the selected channel will
light.

 Locking the panel

By locking the panel you can disable front panel operations
other than controlling the power.
When this unit is used as part of an installed system, you can
lock down the settings by disabling operations from the front
panel, thus preventing inadvertent changes.
After turning the power off, set the rear panel device setup
DIP switch 5 (PANEL LOCK) to the lower position
(LOCK). The next time you turn the power on, the unit will
start up with the front panel locked.
Even in the locked state, you can temporarily defeat the
panel lock by pressing the [FUNCTION] button and the
[SELECT] A button. However, it will be re-locked when any
of the following conditions occur.

• One minutes elapses without any operation being per­formed after the panel is temporarily unlocked

• You press the [FUNCTION] button and the [SELECT] A
button

• You turn the power off

The lock status is shown by the front panel [PANEL LOCK]
indicator.

• Locked: lit

• Not locked: unlit

• Temporarily unlocked: blinking

3. Turn the encoder to gradually raise the
attenuator setting from -99, and verify
that sound is produced from the speaker.

 Switching the mute setting on/off

While holding down the [MUTE] button,
press the [SELECT] button of the channel
that you want to control.

When mute is on, the [MUTE] indicator will light; when
mute is off, the [MUTE] indicator will be unlit.

 Lowering the brightness of the indicators

and the display

If the front panel LED indicators are too bright, you can
lower their brightness.
After turning the power off, set the rear panel device setup
DIP switch 4 (LED DIMMER) to the lower position (ON).
The next time you turn the power on, the unit will start up
with decreased indicator brightness.

NOTE

The brightness of the [POWER] indicator will not be
reduced.

Initializing the Internal Memory

Execute the following procedure when you want to return the internal memory settings to their factory­set state, such as when the amplifier has been moved to a different location.
To initialize the internal memory, power-off the XMV; then set device setup DIP switch 7 to the down­ward position and switch 8 to the upward position, and power-on the XMV.

During initialization, the [NETWORK], [YDIF], and [PANEL LOCK] indicators will blink. When ini­tialization is complete, the [NETWORK] and [YDIF] indicators will blink. Turn off the power; then set
device setup DIP switches 7 and 8 to the upward position (RESUME), and power-on the XMV.

The following memory is initialized.

• Attenuator values

• Polarity settings

• HPF settings

• Analog/digital input setting

• [SIGNAL] indicator display setting

•Event log

* When the unit is shipped from the factory, the device setup DIP switches are all in the upward position.

Either the internal backup battery has run low, or the device has
malfunctioned. Contact your Yamaha dealer.

Make sure that YDIF cables are properly connected.
Use cables that meet the required specifications.

Please check rear panel DIP switch 6 (IP Setting). If DIP switch 6
is set to “PC,” you must use MTX Editor or DHCP server to spec­ify the IP address.

Disconnect unneeded devices from the network.

Change the UNIT ID so that there are no duplicates.

It is likely that the device has malfunctioned; immediately stop
using the device and contact your Yamaha dealer.

Turn the power off, let the power supply cool down, then turn the
power on again.
Continuous high-power output will cause high temperatures, so
please lower the output level. If the temperature is still high,
check whether dirt or a foreign object could have clogged the
cooling fan, and clean the fan if necessary.

For information on possible causes, refer to “[PROTECTON] indi­cators A/B/C/D” (page 8).

It may be that the speaker output connector’s “+” and “-” are
shorted, or that the connected speaker has malfunctioned.

Continuous high-power output will cause high temperatures, so
please lower input level or attenuator. If the temperature is still
high, check whether dirt or a foreign object could have clogged
the cooling fan’s air intake, and clean it if necessary.

Interruption

Total impedance

No sound

For a high-impedance connection a speaker transformer that raises the impedance to several hundred
or thousand ohms is added to the speaker system. This allows the speaker system to be effectively driven
with much lower current than is required for a low-impedance system. That, in turn, makes it possible to
connect a larger number of speaker systems to each power amplifier output. High-impedance speaker
connections work at a specific maximum voltage — usually 70 or 100 volts — and are therefore also
referred to as “constant voltage” speaker systems (the label “constant voltage” is somewhat misleading:
the actual output voltage fluctuates according to the input signal).
For a more orthodox low-impedance speaker connection, the power amplifier is directly connected to a
speaker system that has an inherent impedance of 4 – 16Ω.

The difference between these types of connection are outlined below.

Multiple Speaker System Drive Capa­bility

 High Impedance

As long as the total nominal power input rating for all speak­ers is within the power output capability of the amplifier, any
number of speaker systems can be connected in parallel. In a
high-impedance installation, the power input rating is deter­mined by the speaker transformers used.
If the 280W output XMV4280 is used with a speaker system
having speaker transformers that make the rated input 10W,
you can connect a speaker system with a maximum of 24
speakers per channel based on the calculation (*), giving you
a total of up to 96 speakers for the four channels. In a high­impedance installation it is also possible to simultaneously
drive speaker systems that have different input power rat­ings.

(*) Yamaha recommends that you allow a 20% margin to

this number, considering variations in the transformer’s
primary impedance, possible tap changes in the future,
and the addition of speakers.

 Low Impedance

Normally only one speaker system is connected to each
amplifier channel, as shown in the diagram.
This means that the number of speaker system that can be
connected to an XMV is limited to four.
However, even with low impedance connections, there is a
way by which multiple speaker systems can be connected to
one channel.
When multiple speakers systems having the same impedance
are connected in parallel, the total impedance becomes the
individual speaker system impedance divided by the number
of systems connected. This means that if the XMV is set to
4Ω, up to two 8Ω speaker systems can be connected to one
channel.

4Ω

8Ω 8Ω 8Ω

The second method is series connection. In this case the total
impedance is simply the sum of the impedances of the
speaker systems connected. But as you can see in the series
connection wiring diagram, if one speaker system fails the
second speaker system will be affected as well.

Transmission Distance and Efficiency

The cables that transmit electric signals have resistance. The
resistance in short cables is small enough that it can be ignored,
but as transmission distance and cable length increase, resis­tance can increase to the point that signal loss and degradation
occur. That can mean reduced output level and sound quality.
Below we examine the merits and demerits of low-impedance
and high-impedance connections in relation to transmission
over significant distances.

 High Impedance

Even if the cable resistance reaches 8Ω due to an extended
transmission distance, this is an amount that can be ignored
relative to the impedance of the speaker system, meaning
that transmission loss due to the cable will be insignificant,
and thus will have little effect on the transmission efficiency
of the electrical signal.

 Low Impedance

For short distances over which cable resistance is insignifi­cant, low-impedance connection allows the power amp to be
directly connected to the speaker system without the need
for speaker transformers. That means that the full perfor­mance potential of amp and speakers can be taken advantage
of for sound quality that is superior to high-impedance
installations. And since only one speaker system is usually
connected to each amplifier channel, different audio signals
can be sent to each speaker system, or “zone,” as required.
But in a situation like the one shown in the diagram, where a
long cable with a resistance of 8Ω is required, transmission
loss will theoretically result in the output level being reduced
by half because the impedance of the speaker system itself is
only 8Ω. Half of the power gets absorbed by the cable, and
only the remaining half is available to drive the speaker. So
for low-impedance installations it is necessary to either keep
the cables short enough that cable resistance is not an issue,
or use thicker cables that have lower resistance for longer
runs, for example.
