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.

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

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

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.

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.
