• 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.

Wiring of the [SPEAKERS] Connectors

Turn off the POWER switch before connecting external devices to the TXn.

Remove about 13mm of insulation from the end of each

speaker cable, and pass the bare wire through the holes in

the appropriate speaker terminals. Tighten the terminals to

securely clamp the wires. Be sure that the bare wire ends do

not jut out from the terminals and touch the chassis.

From above, insert the Y-plugs all the way into the opening,

and tighten the terminals.

Insert the Speakon cable plug (Neutrik NL4) into the con-

nector, and turn it to the right to lock it.

Network Connection Example

If you connect the TXn units’ [NETWORK] connector to a computer via an Ethernet cable, you’ll be able to mon-

itor/control the TXn units from Amp Editor. Including computers and other equipment, a total of up to 253 units

can be connected in a single network.

• If you wish to connect multiple TXn units, use a network switch that supports 100Base-TX/10Base-T.

• The Ethernet cable between the network switch and the TXn can be up to 100 meters long. Due to the quality of cables and net-

work switch performance, however, proper operation at the maximum length cannot be guaranteed in some cases.

• Since the TXn supports Auto MDI/MDI-X, it will automatically detect whether the connected cable is of the straight type or

crossover type, and will conﬁgure itself to create the optimal connection. Therefore, you can use either a straight or crossover

cable.

•To prevent electromagnetic interference, use an STP (Shielded Twisted Pair) cable.

• Refer to the Amp Editor Installation Guide and the Amp Editor Owner’s Manual for information on the TXn initial setup for using

the TXn in a network.

Troubleshooting

Initializing the internal memory

You can initialize the amp’s internal memory. As desired, you can initialize the following two types of data.

• User Data: Initialize all user data except for the event log and speaker processor library.

• Library: Initialize only the speaker processor library.

• When you initialize the internal memory, the settings that had been stored will be lost. Use the following procedure with

caution.

1. Power-off the TXn.

2. While holding down the [HOME] key, turn on the power; the Initialize screen will appear.

3. Use encoder A to select the data that you want to initialize, and press the [ENTER] button to execute initial-

ization.

When initialization is completed, the amp will automatically restart.

• During initialization, the display will show the message “Do not turn off!” Never turn off the amp while this message is

displayed.

Symptom Possible causes Response

No sound from the

speaker

The cable is not connected properly. Make the correct connections to the audio input jack and the

speaker output jack.

The gain or attenuator setting has low-

ered the level.

Gain is adjusted by the MENU screen → General → Sensitiv-

ity/Amp Gain. Attenuator is adjusted by turning the encoder in

the HOME screen.

The [MUTE] button is on. If the front panel [MUTE] indicator is on, hold down the

[MUTE] button for one second or longer to cancel muting.

The protection circuit has operated, mut-

ing the output.

If the ampliﬁer has overheated, clean the ﬁlter elements and

improve the ventilation around the ampliﬁer. If the power sup-

ply has malfunctioned, contact your Yamaha dealer.

Noise from the speaker The word clock from the slot input is not

synchronized with the master clock.

Select the word clock from the slot as the master clock, or

turn Auto Scan Mode on.

Analog input level is exceeding the input

sensitivity setting.

Adjust MENU screen → General → Sensitivity/Amp Gain set-

ting according to the input level.

An alert message is dis-

played

An ampliﬁer malfunction or other alert event

related to the ampliﬁer audio has occurred.

For details on the meaning of each alert message and the appro-

priate measures to take, refer to the Amp Editor Owner’s Manual.

Panel operations are not

accepted

The unit is locked. Refer to “Front Panel Operation” in the TX6n/5n/4n Reference

Manual.

A scene can be saved

but not recalled

Scene Recall Enable is turned OFF. Turn the UTILITY screen → Scene Setup → Scene Recall

Enable setting ON.

Library can be recalled,

but not saved

You cannot save library data from the

TXn front panel.

Save the library data from Amp Editor.

All scene data saved in

the TXn has disappeared

The power was turned off while the TXn’s

data was being saved.

If you saved the project in Amp Editor, synchronize from Amp

Editor to the TXn.

To return to the default

parameter values

–

Recalling a scene 00 (default setting scene) will return all the

parameters other than those in the UTILITY settings to their

default values. The TXn allows you to edit a wide variety of

parameters, but can also be used as an analog ampliﬁer by

returning to the default parameter values. Default values of

the main parameters are STEREO for ampliﬁer mode, 26dB

for gain, and -∞dB for attenuation.

Refer to the TX6n/5n/4n Reference Manual for detailed infor-

mation on scenes.
