NOTICE

To avoid the possibility of malfunction/ damage to the product, damage to data, or damage to other property, follow the notices below.

 Handling and maintenance

• Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile phone, or other electric devices. Otherwise, the device,

TV, or radio may generate noise.

• Do not expose the device to excessive dust or vibration, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car

during the day), in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the internal components.

• Do not place vinyl, plastic or rubber objects on the device, since this might discolor the panel.

• When cleaning the device, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wip-

ing cloths.

• 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 o

ccurr

ed, leave the device for several hours without turning on the

power until the condensation has completely dried out.

• Do not use this device for any purpose other than driving loudspeakers.

• When turning on the AC power in your audio system, always turn on tthe device LAST, to avoid speaker damage. When turning the

power off, the device should be turned off FIRST for the same reason.

 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. When the remaining capacity of the

backup battery becomes so low that it needs to be replaced a “012.” message will appear on the display during operation or when the

device is powered on. If either of these messages appears do not turn off the power and immediately transfer any data you want to save

to a computer or other external storage device, then have qualif

ied Yamaha service

personnel replace the backup battery. The average

life of the internal backup battery is approximately 5 years, depending on operating conditions.

* Data items maintained in the internal memory by the backup battery are as follows:

•Device parameters (Attenuator values, Polarity settings, HPF settings, Analog/digital input setting, and [SIGNAL] indicator display

setting).

•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.

Thank you for your purchase of the Yamaha XMV4280, XMV4140, XMV4280-D or XMV4140-D 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.

The XMV is a multi-channel power amplifier with the follow-

ing features.

• Both high-impedance and low-impedance connec-

tions 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 con-

nections 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

(XMV4280/XMV4140 only)

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.

• Dante network for large-scale systems

(XMV4280-D/XMV4140-D only)

This enables audio signal transfer over long-distance with

Dante equipped devices (such as the MTX5-D) with stan-

dard Ethernet cables.

•High efficiency

The newly-developed output circuits allows high efficiency.

• Redundancy between the digital and analog inputs

When the pilot tone of a digital input is interrupted or an

analog input reaches the specified level or higher, the input

switches from digital to analog.

Use the MTX-MRX Editor or the Amp Editor to update the

firmware of the XMV or check the firmware version. For opera-

tion details, refer to the related manuals.

You can download the latest firmware from the “Downloads”

page on the following website.

http://www.yamahaproaudio.com/

The XMV4280-D/XMV4140-D units feature 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) net-

work. Dante also offers the following benefits:

• It transmits up to 512 in/512 out, for a total 1024 channels

(theoretically) of audio over a GbE network.

(The XMV4280-D/XMV4140-D features four inputs with a

24/32-bit resolution.)

• Dante-enabled devices will automatically configure their

network interfaces and find each other on the network. You

can label Dante devices and their audio channels with names

that make sense to you.

• Dante uses high accuracy network synchronization standards

to achieve sample-accurate playback with extremely low

latency and jitter.

(Four types of latency are available on the XMV4280-D/

XMV4140-D: 0.25 msec, 0.5 msec, 1.0 msec, and 5.0 msec.)

• Dante supports redundant connections via primary and sec-

ondary circuits to defend against unforeseen difficulties.

• Connecting a Dante-enabled device to a computer over

Ethernet enables you to directly input or output audio signals

without using any audio interface devices.

Firmware Updates

About Dante

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 perfor-

mance 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.

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 pan-

els to minimize the possibility of heat buildup.

• To ensure sufficient airflow, le

ave 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.

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 17). When rackmounting your

equipment, use a lacing bar when possible to bun-

dle and fasten the cables.

• If cables will be frequently connected and discon-

nected, as in the case of a portable installation, we

recommend that you use f

errules

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).

sections.

 When using low impedance connections (page

17)

 When using low impedance connections with

Double Power mode (page 18)

 When using high impedance connections

(page 18)

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

 When using low impedance connections

Depending on the impedance (4Ω or 8Ω) of the connected

speakers, set the [SPEAKERS] DIP switches as follows.

NOTE

A slotted screwdriver with a blade width of about 3 milli-

meters is recommended.

If you use Double Power mode, input/output will be dis-

abled for channels B and D.

Depending on the impedance (4Ω or 8Ω) of the connected

speakers, set the [SPEAKERS] DIP switches as follows.

 When using high impedance connections

Depending on the specifications (70V or 100V) of the

system in which this unit is being installed, set the

[SPEAKERS] DIP switches as follows.

 Connecting Speaker Cables

The [SPEAKERS] output connectors (page 15) on the rear

panel are barrier strip type connectors. We will explain con-

nections using a spade lug and connections using a bare con-

ductor.

tion (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 polarity will be reversed.

TIPS

Since a large amount of current can flow in a speaker

cable, a magnetic field will be generated. If sensitive cir-

cuits 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

(page 15) on the rear panel. First connect the AC power cord

to the connector on this unit, then plug it into an appropriate

AC power outlet.

 Turning the Power On

Use the front panel power switch (page 9) to turn the power

on.

 Enabling Analog Input

Using the front panel, enable analog input as follows.

1. While holding down the [FUNCTION] but-

ton, turn the encoder to make the display

indicate “SRC.”

The control mode will change to “Analog/digital input

selection.”

2. Press the [SELECT] button of the channel

for which you want to enable the analog

input.

The [SELECT] indicator of the selected channel will

light.

3. Take your finger off the [FUNCTION] button,

and turn the encoder to make the display

indicate “ANA.”

Input from the analog input connectors will be enabled.

 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 connec-

tions, the 80 Hz HPF will be enabled.

If you want to change this setting, proceed as follows.

1. While holding down the [FUNCTION] but-

ton, 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.

CAUTION

You must turn off the power before connecting the

power cord.

CAUTION

Before you turn the power on, make sure that audio

signals are not being input to the analog input connec-

tors. 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 pro-

tection circuit will operate immediately when the power

is turned on. Check whether there might be a problem

with the wiring.

NOTE

If a certain period of time elapses without any operation

being performed, the unit will return to Attenuation set-

ting operating mode.

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 con-

nections, we recommend that you change the HPF

setting to 40 Hz.

•If you’re using a full-range speaker with high-imped-

ance connections, the amplifier’s protection circuit may

operate if the HPF is set to other than 80 Hz. We rec-

ommend that you use the 80 Hz setting.

• If a certain period of time elapses without any opera-

tion being performed, the unit will be placed in Attenua-

tion setting operating mode.

NOTE

If the device is set as follows, the HPF settings will be

changed automatically.

 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.

 Changing the attenuator setting

Here’s how to change the attenuator setting.

1. While holding down the [FUNCTION] but-

ton, 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.

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.

 Locking the Front Panel

By locking the panel you can disable front panel operations

other than controlling the power (front panel lock).

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 per-

formed 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: flashing

NOTE

If the speakers are remotely located and you are unable to

check the signal output easily, changing the [SIGNAL] indi-

cator (page 10) setting to “output” will allow you to check

whether current is flowing to the speakers. For details on

switching the indicator setting, refer to “Front Panel Opera-

tions” (page 23).

NOTE

The brightness of the [POWER] indicator will not be

reduced.
