Introduction
Terms
This section explains terminology specific to the TXn.
Amp Editor
This is computer application software. This software allows you to monitor and control the TXn amplifiers from your com-
puter.
Scene
Settings such as power-on/standby or mute for each amplifier are called a “scene.” By recalling a scene, the saved settings
can be immediately applied to the amplifiers. Each TXn unit has 50 scenes.
Signal Path
This is the audio signal processing functionality provided by the internal DSP. Components organized into modules accord-
ing to their functionality are placed in the signal path.
Component
These are modules in the signal path that organize audio signal processing according to their functionality.
Library
The settings of all Speaker Processor components can be saved together in a library. A library can be saved only from Amp
Editor, but can be recalled from the unit’s front panel as well.
Device ID
This is an ID for uniquely identifying a TXn unit within a network. In order to allow monitoring and control from Amp Edi-
tor, you must specify non-conflicting IDs within a workspace.

Controls and Connectors
t [PROTECTION] indicator
When the protection system is active, this indicator will light red. The protection circuit will operate in the following situa-
tions.
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 only if shut-down occurs.
The thermal meter in the METER screen and in Amp Editor indicates the heat sink temperature of the amp section.
The temperature of the power supply section is not shown.
If the load falls below 0.5 ohms
If a short occurs and the load falls below 0.5 ohms, the speaker output will be muted, and muting will be cleared approx-
imately 1 second later.
If DC output is detected
The speaker output will be muted, and the power supply section will shut down.
If the power supply malfunctions
The speaker output will be muted.
If ultra-high frequencies, overcurrent, excessive total current, or maximum current is detected
The speaker output will be compressed.
y [BRIDGE] indicator
This will light green if the amplifier mode is set to Bridge.
u [PARALLEL] indicator
This will light orange if the amplifier mode is set to Parallel.
i [MUTE] indicator
This indicator will light red if muting is turned on by the [MUTE] button or from Amp Editor. When the power is turned on,
the output signal will also be muted and the indicator will blink red until audio begins being output.
•Even if mute is off, this indicator will blink if Solo was turned on from Amp Editor, or when the output has been muted by
the protection circuit.
o [MUTE] button
By holding down the [MUTE] button for one second or longer, you can turn muting on/off for that channel. When muting
turns on, the [MUTE] indicator will light. By holding down the [MUTE] button when the Solo function is turned on from
Amp Editor, Solo will be defeated.
!0 [ALERT] indicator
This will light to indicate an alert related to the amplifier’s audio signal. If an alert for a specific channel has occurred, the
indicator of the corresponding channel will light; for other alerts, the indicators of both channels will light. At this time, the
alert message will appear in the upper part of the display.
!1 [CLIP] indicator
When the signal of the speaker output’s power amp section exceeds the clipping level, this indicator will light and the output
signal will be compressed.
!2 [SIGNAL] indicator
This will light green when the level of the signal being output from the [SPEAKERS] jack exceeds 1 Vrms (equivalent to
0.2 W into an 8 ohms load, 0.4 W into a 4 ohms load or 0.8 W into a 2 ohms load).

Controls and Connectors
!3 Encoders A, B
When the display shows the attenuation meter, these encoders adjust the attenuation of channels A and B. If any other
screen is displayed, encoder A moves the cursor and encoder B modifies the parameter value.
Only encoder A can be operated if you’re adjusting the attenuation when the amplifier mode is Bridge.
!4 Display
This shows the amplifier’s settings or a level meter. Refer to “Screen Structure” (page 13) for details.
If the power supply is in Standby mode or if the LCD Setup’s Backlight setting is Auto OFF, the backlight will go dark if no
panel operation has been performed for ten seconds. It will light again when a panel operation is performed.
!5 Function buttons
These buttons move to the screen indicated above each button in the display. If a channel name (e.g., CH A, CH B) is
shown, this means that a parameter for that channel is displayed; press the corresponding function button to switch the
channel that is shown. These buttons may also operate in different ways depending on the screen shown in the display.
!6 [HOME] button
This accesses the HOME screen (page 15) in the display.
By holding down this button for three seconds or longer, you can switch the power between Standby and On modes. When
the confirmation message appears, press the [ENTER] button to switch the setting.
!7 [EXIT] button
By pressing this button when the display shows a screen other than the HOME screen, you can move to the screen of the
next highest level.
•To temporarily disable panel lock, simultaneously hold down the [HOME] button and [EXIT] button for three seconds or
longer.
If you hold down this button for three seconds or longer in the HOME screen, the FAULT OUTPUT connector output will
be reset (NC and C will be connected).
!8 [ENTER] button
Use this to select a parameter or to finalize an edited parameter value. Depending on the screen shown in the display, this
button may also be used in other ways. If the parameter value is blinking, you must finalize the value by pressing this but-
ton.
If you hold down this button for one second or longer in the HOME screen, the UTILITY screen Device Setup page (page
19) will appear.
!9 Air intakes
The amplifier uses forced-air cooling. The variable speed cooling fan draws air in from the front and exhausts it through the
rear. The cooling fan speed varies depending on the heat sink temperature: It operates at low speed when it is below 40 °C
(40%), increases in speed according to increases in temperature, and operates at high speed when temperature exceeds 60
°C (60%). If the power supply exceeds 90°C, the variable speed fan will operate at high speed regardless of the heat sink
temperature.
Please be sure that you do not block the air intakes or exhaust vents. Also, clean the filter elements regularly. If the air
intakes are clogged with dust or debris, the amplifier will overheat, which may result in the amplifier shutting down.
@0 Screw holes for handles
These four screw holes (four locations) are for the included handles. Fix the handles to the amplifier, using the included flat-
head screws.

Controls and Connectors
@1 [SPEAKERS] jacks
These are speaker output jacks.
Speakon connectors : Speakon type cable plugs (Neutrik NL4) can be connected here.
Five-way binding post connectors : Bare wires or Y plugs can be connected here.
The five-way binding post connectors and Speakon connectors are internally connected in parallel. If you’re using both
simultaneously, make sure that the speaker impedance of each connector is 4–16 ohms (8–32 ohms in Bridge mode).
@2 Digital input/output connectors (I/O card slot)
An AES-IO card is installed as standard, allowing AES/EBU digital audio signals to be input and output.
• [IN] connector : This is an XLR-3-31 type balanced input connector for inputting two-channel digital audio sig-
nals.
• [OUT] connector : This is an XLR-3-32 type balanced output connector for outputting two-channel audio signals
processed by the internal DSP.
• [THRU] connector : This is an XLR-3-32 type balanced output connector that outputs the unprocessed signal received
at the [IN] connector. Even if the power is turned off, this connector will output the input signal
without any change (page 44). However, internal settings will be switched when the power is
switched on/off, causing the output signal to be muted for an instant.
If desired, you can remove the AES-IO card and install a separately sold MY card. For details on the types of MY card
that can be used and how to install them, refer to “Optional I/O cards” (page 9).
The removed AES-IO card cannot be installed and used in other devices.
•You must use a 110 ohm digital cable to make AES/EBU connections.
@3 Analog input/output connectors
These connectors input and output analog audio signals.
• [IN] connector : These are XLR-3-31 type input connectors for inputting ana-
log audio signals. The pin polarity is shown at right (IEC
60268).
In Parallel mode and Bridge mode, only the signal of
channel A is output from the speaker output connector
by default. The channel B signal is not sent from the
speaker output, but the audio signal processed by the
internal DSP can be output from the digital output con-
nector.
• [THRU] connector : This is an XLR-3-32 type balanced output connector
that outputs the unprocessed analog signal received from
the [IN] connector.

@4 [NETWORK] connector
This is a 100BASE-TX/10BASE-T Ethernet connector. You can connect this to a computer so that the amplifier can be mon-
itored and controlled from Amp Editor. This also allows an external controller such as AMX or Crestron to be connected.
•To prevent electromagnetic interference, use an STP (Shielded Twisted Pair) cable for the [NETWORK] connector.
@5 [FAULT OUTPUT] connectors
This is a 3P Euroblock connector for controlling an external analog device when an abnormality occurs in the CPU or trig-
gered by the occurrence of a Fault event specified in Amp Editor. NC and C will be connected when the amplifier is operat-
ing normally; NO and C will be connected when a problem occurs (page 51). You can also reset this output from Amp
Editor.
A message will appear in the screen if a problem occurs. To reset the output, hold down the [EXIT] button for three seconds
or longer in the HOME screen.
@6 Power cable
Connect the plug of the power cable to an AC outlet of the correct voltage.
@7 Grounding screw
The AC power cord is a 3-wire type. If the AC outlet used is earthed (grounded), this device will be properly earthed as well.
Also, grounding the screw sometimes reduces hum and interference noise.
Supported I/O cards
You can remove the AES-IO card from the TXn’s rear panel, and install a separately sold MY (mini-YGDAI) card. As of Sep-
tember 2009, the following MY cards are supported. For the latest information, refer to the Yamaha pro audio website.

Parameters that can be edited
The parameters that can be edited will depend on the meter type.
* The setting range will differ depending on the meter type.
Parameter Range Explanation
Detect Enable ON/OFF Specifies whether alert detection will be enabled or disabled. An alert
message will be displayed if a point exceeding the specified value (Alert
Min/Max TH) is detected for the specified number of times (Detect
Count) within the specified duration (Detect Time). Detection is in 2 ms
intervals.
Alert Min TH * Specifies the lower threshold value for the alert.
Alert Max TH * Specifies the upper threshold value for the alert.
Detect Time 1–10s Specifies the time during which points exceeding the threshold value will
be counted.
Detect Count 1–100 Specifies the number of times that a point exceeding the threshold value
must be counted in order to trigger an alert.
Peak Hold ON/OFF Turns peak hold on/off.
Unit * Specifies the display unit for the meter.

Panel Operations
Here you can make settings for the amplifier itself and for the network.
Setting procedure
1. In the HOME screen, press the second-from-left function button (UTILITY) to access the UTILITY screen.
2. Use the function buttons (PREV/NEXT) to access the screen for the sub-category whose settings you want to
change.
3. Use encoder A to move the cursor to the parameter that you want to edit, and encoder B to edit the parameter
value.
4. If the parameter value is blinking, press the [ENTER] button to confirm the value.
Non-blinking parameter values are reflected by the amplifier in real time.
Device Setup
Here you can specify identifiers for distinguishing the amplifier on a network.
•You can also access this screen from the HOME screen by holding down the [ENTER] button for three seconds or longer.

Word Clock Setup
Here you can select the master word clock that will synchronize digital audio signal processing.
q Fs
Indicates the current word clock frequency.
w Int
The status of the internal word clock. There are four possibilities: 44.1 kHz / 48 kHz / 88.2 kHz / 96 kHz. The default setting
is 96 kHz.
e Slot
The word clock status of the card inserted in the slot. Normally, the reference word clock signal is transmitted from a single
device, and the other devices will receive and synchronize to this word clock signal.
If a card with a built-in SRC (sampling rate converter) is installed, select the master word clock from other than the chan-
nels with the SRC enabled.
r Auto Scan Mode
This specifies whether the master clock will be switched automatically when a valid word clock is no longer being input to
the port that’s assigned as the master clock, or when a port of the slot is found to have a valid word clock being input while
the internal word clock is selected.
If this setting is ON, the master clock will automatically be switched according to the following order of priority.
1. The selected port of the slot
2. The internal word clock
•For some types of installed I/O card (e.g., for an AD card), Auto Scan Mode will not operate even if this setting is ON.
Refer to “Supported I/O cards” (page 9) to check if your I/O card supports Auto Scan Mode.
If two TXn amplifiers are bi-directionally connected via a digital I/O card (e.g., separately sold AES/EBU cards connected
via the D-sub 25 pin connectors), and if Auto Scan Mode is ON for both units, the word clock will loop, and will no longer
lock. In this case, turn Auto Scan Mode OFF for one of the TXn amplifiers.
Setting procedure
1. Use encoder A to move the cursor to the port (Int or Slot) that you want to assign as the master clock.
2. Press the [ENTER] button to switch the master clock.
A word clock is being input, and can be selected as the master clock.
A valid word clock is not being input (and cannot be selected as the master clock).
A word clock is being input, but is not synchronized with the master clock.
Selected as the master clock.
Selected as the master clock, but a valid clock is not being input.
An invalid channel of the slot, an analog I/O card is installed, or no card is installed.
