CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or
damage to the device or other property. These precautions include, but are not limited to, the following:
Power supply/Power cord
• Remove the electric plug from the outlet when the device is not to be used
for extended periods of time, or during electrical storms.
• When removing the electric plug from the device or an outlet, always hold
the plug itself and not the cord. Pulling by the cord can damage it.
Location
• Before moving the device, remove all connected cables.
• When setting up the device, make sure that the AC outlet you are using is
easily accessible. If some trouble or malfunction occurs, immediately turn
off the power switch and disconnect the plug from the outlet. Even when the
power switch is turned off, electricity is still flowing to the product at the
minimum level. When you are not using the product for a long time, make
sure to unplug the power cord from the wall AC outlet.
• If the device is mounted in an EIA standard rack, carefully read the section
“Precautions when rack-mounting the unit” on page 6. Inadequate
ventilation can result in overheating, possibly causing damage to the
device(s), malfunction, or even fire.
• Do not use the device in a confined, poorly-ventilated location. If this
device is to be used in a small space other than an EIA-standard rack, make
sure that there is adequate space between the device and surrounding walls
or other devices: at least 10cm at the sides, 15cm behind and 40cm above.
Inadequate ventilation can result in overheating, possibly causing damage
to the device(s), or even fire.
• Do not expose the device to excessive dust or vibrations, or extreme cold
or heat (such as in direct sunlight, near a heater, or in a car during the day)
to prevent the possibility of panel disfiguration or damage to the internal
components.
• Do not place the device in an unstable position where it might accidentally
fall over.
TX6n/5n/4n Owner’s Manual

• Do not block the vents. This device has ventilation holes at the front/rear to
prevent the internal temperature from becoming too high. In particular, do
not place the device on its side or upside down. Inadequate ventilation can
result in overheating, possibly causing damage to the device(s), or even fire.
• Do not use the device in the vicinity of a TV, radio, stereo equipment,
mobile phone, or other electric devices. Doing so may result in noise, both
in the device itself and in the TV or radio next to it.
Connections
• Before connecting the device to other devices, turn off the power for all
devices. Before turning the power on or off for all devices, set all volume
levels to minimum.
• Use only speaker cables for connecting speakers to the speaker jacks. Use
of other types of cables may result in fire.
• Do not place the device in a location where it may come into contact with
corrosive gases or salt air. Doing so may result in malfunction.
Maintenance
• Inspect the cooling fan air filter and clean it periodically (see the reference
manual (PDF file)). Dust and dirt can seriously degrade the effectiveness of
the cooling fan and result in malfunction or fire.
• Remove the power plug from the AC outlet when cleaning the device.
Handling caution
• When turning on the AC power in your audio system, always turn on the
device LAST, to avoid speaker damage. When turning the power off, the
device should be turned off FIRST for the same reason.
(5)-6 1/2
• 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 damage. 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.
• Do not insert your fingers or hands in any gaps or openings on the device
(vents, ports, etc.).
• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into
any gaps or openings on the device (vents, ports, etc.) If this happens, turn
off the power immediately and unplug the power cord from the AC outlet.
Then have the device inspected by qualified Yamaha service personnel.
• Do not use the device or headphones for a long period of time at a high or
uncomfortable volume level, since this can cause permanent hearing loss.
If you experience any hearing loss or ringing in the ears, consult a
physician.
• Do not rest your weight on the device or place heavy objects on it, and
avoid use excessive force on the buttons, switches or connectors.
• Do not use this device for any purpose other than driving loudspeakers.
Backup battery
• 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 “Critical Battery” or “No Battery” 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 qualified 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:
• Current scene parameters and number.
• Device parameters (Utility, AnalogInputMeter, SpeakerOut meter, etc.).
• 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.
XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-).
Use only Neutrik NL4 plugs for connecting Speakon connectors.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed.
Always turn the power off when the device is not in use.
The performance of components with moving contacts, such as switches,
volume controls, and connectors, deteriorates over time. Consult qualified
Yamaha service personnel about replacing defective components.

Precautions when rack-mounting the unit
Operation of this device is guaranteed for an environmental temperature range of 0 – 40°C. If you are
mounting only this device in an EIA standard rack, you may mount multiple units without leaving a space
between them. If you are mounting this device along with other types of device in an EIA standard rack,
the ambient temperature inside the rack may rise due to heat produced from the other devices, preventing this device from performing as designed. To ensure that heat does not build up inside this device,
you must observe the following conditions when mounting it in a rack.
• If you mount this device in a rack together with heat-generating devices such as power amps made by
other companies, you must leave 1U or more space between this device and other devices. You
should also install a ventilation panel in this space or leave it open to ensure adequate ventilation.
• Leave the back of the rack open, and allow 10 cm or more distance between the rack and the wall or
ceiling to ensure adequate ventilation. If you are unable to leave the back of the rack open, you must
install a commercially available fan kit or other forced air circulating system to the rack. If you have
installed a fan kit, there may be cases in which closing the back of the rack will provide better cooling.
For details, refer to the instructions that came with the rack system or fan kit.

Introduction
Thank you for purchasing the Yamaha TX6n, TX5n, TX4n Power Amplifier. In order
to take full advantage of the TX6n/TX5n/TX4n’s (TXn) functionality and to ensure
trouble-free operation, please read this owner’s manual carefully before use. After you
have read the manual, keep it in a safe place for reference when needed.
Features
The TXn series are high audio quality, high efficiency, high reliability, low impedance drive power amplifiers that
utilize Yamaha’s famed DSP and digital audio networking technology.
■ Flexible support for analog and digital audio formats
In addition to two-channel analog input, these amplifiers come with an AES/EBU card installed in their MY card slot,
allowing digital signals to be input and output. Separately sold MY cards can be installed in this MY slot to support a variety of digital audio formats.
■ Monitor and control from Amp Editor
By connecting a computer in which the “Amp Editor” application software is installed, the computer can be used to monitor
the TXn units, or to control the TXn units such as switching the amplifier power’s Standby/On and mute status. This monitoring and control can also be performed from the panel of the TXn unit.
■ Versatile speaker processing
Since signal processors such as equalizer, delay, and crossover are built in, the use of external equipment can be minimized.
These can be controlled from the panel of the TXn unit or via Amp Editor. Speaker processor libraries created on the
Yamaha DME series or the SP2060 can also be used.
About Setup
■ Attaching the handles
You can attach the handles to the amplifier using the supplied flat-head screws.
Follow the steps below to attach the handles:
1. Remove the rack mount brackets.
2. Attach the handles to the amplifier by tightening the flat-head screws into the four screw holes for each handle.
3. Replace the rack mount brackets.
■ Adjusting the position in the rack
If there is insufficient space between the rear of the amplifier and the rack, you can adjust the position of the rack mount
brackets so that the front panel of the amplifier protrudes from the front of the rack by 22 mm.
