POWER AMPLIFIERS
High Power Touring Amplifiers
with Internal DSP
and Advanced Networking Capabilities

Solid Power and Stunning Audio Quality
with Built In Processing
• High power for touring applications plus stable 2-ohm drive capability for line array speaker systems.
• Yamaha DSP technology provides extensive monitoring, control, input/speaker processing, and protection functions built in.
• Card slot makes it easy to match the amplifier’s I/O configuration to the system –– analog or digital.
• Failsafe redundant input configuration using both the analog XLR and the card slot inputs.
• Legendary Yamaha quality control for consistently superior sonic quality and reliability.
There was a time – not so long ago – when all a professional power amplifier had to do was amplify. But with increasing system demands and
requirements for reproduction quality, the need for additional support equipment increased dramatically, leading to configurations of
mind-boggling complexity. Racks of mixers, equalizers, crossovers, limiters, delays, and more became necessary just to handle output processing.
Yamaha TXn series power amplifiers combine outstanding audio power performance with industry-leading Yamaha digital signal processing
technology to give you total output capability in astonishingly compact 2U-size amplifiers. But there’s more. You also get unmatched flexibility to
choose the input/output configuration and format that best suits your needs, while comprehensive networking capability lets you monitor and
control complex multi-amp systems from a laptop computer. With the appropriate I/O cards these advanced amplifiers are also fully compatible
with CobraNet or EtherSound audio networks. And if you’re driving line array speaker systems you’ll appreciate the fact that every one of these
amplifiers can comfortably drive 2-ohm loads with total stability and reliability.
These revolutionary power amplifiers not only deliver high power and staggering sonic quality, but they also feature all monitoring, control,
processing, and protection functions you need to achieve optimum performance in systems of any size or complexity built right in. The power amp
of the future does much more that just amplify. The power amp of the future is here.

When speakers are connected in parallel, often the case with subwoofers or line
arrays, stability at lower impedance becomes extremely important. The actual
impedance curve of a speaker unit is complex and its load varies greatly
depending on frequency. The actual impedance of a speaker is often lower than
its nominal impedance under certain frequencies, putting excessive stress on
the amplifier especially if multiple speakers are connected in parallel. The TXn
series are designed to perform with ease even under demanding low impedance
conditions, always maintaining top quality performance. Some of the many
refinements implemented to provide stable low-impedance drive capability
include newly developed thin-film power transistors and flat-wire power
transformer windings to minimize heat loss. Many other details contribute, but
the final result is totally stable drive capability down to two ohms.

On top of the outstanding basic performance offered by the TXn series power
amps, they are equipped with some of the most advanced and flexible DSP
(Digital Signal Processing) capabilities available. Yamaha is an acknowledged
leader in the field of digital signal processing, and the full weight of that
technology has been brought to bear in these cutting-edge power amplifiers. All
three TXn models incorporate advanced 24-bit 96-kHz DSP capability that
employs Yamaha’s own DSP7 LSI (the same LSI that provides the processing
power for Yamaha’s industry-standard digital mixing consoles) as well as
powerful SHARC processing technology. In addition to outstanding sound quality
and low latency, an extraordinary selection of control and processing
capabilities are provided, ranging from basic amplifier settings through input
and speaker processing to comprehensive status monitoring. The built-in input
and speaker processing capabilities are so extensive and powerful, in fact, that
external processors will be unnecessary in many applications. The onboard DSP
parameters and functions can be accessed directly through the LCD and button
interface provided on the front panel of the amplifier, or via Yamaha's
NetworkAmp Manager II software running on a computer connected via
Ethernet. NetworkAmp Manager II control provides additional advantages and
capabilities for controlling large systems that employ numerous amplifiers
(NetworkAmp Manager II is discussed in more detail on the following page).
Versatile Onboard DSP
The chart below lists most of the monitoring, control, and processing functions
provided by the TXn series amplifiers. Unless otherwise noted these functions
can be accessed directly via the amplifier’s own display and controls. The
NetworkAmp Manager II software described on the following page offers more
comprehensive displays and easier control, as well as centralized management
of entire multi-amplifier systems.
DSP Features and Functions
The TXn amplifiers feature a dual mono configuration: the mono amplifiers
are arranged symmetrically on each side of the chassis, each with its own
independent power supply. This configuration effectively eliminates
performance-degrading interference between channels while maintaining
optimum separation and superior definition under all operating conditions
and with all types of source material. Sudden high power demands in one
channel will not affect the performance of the other, for example. The two
power supplies operate in opposing phases to cancel noise while minimizing
electromagnetic interference.
Dual-mono Configuration with Independent Power Supplies
Original Yamaha EEEngine technology reduces power consumption by
approximately 50% compared to conventional amplifiers while maintaining
full Class AB reproduction quality and fast response. Power mains quality and
capacity become significant issues in large-scale live sound systems, but the
ability of the TXn series amplifiers to deliver high power output with
dramatically reduced power consumption goes a long way towards alleviating
the problem. In addition to less susceptibility to imperfect mains supplies,
lower power consumption also achieves reduced heat generation, significantly
increasing part life and reliability. In order to achieve stable 2-ohm drive
capability the EEEngine circuitry in the TXn series amplifiers features a newly
developed high-efficiency FET current buffer drive circuit. Only Yamaha can
deliver this level of high efficiency and stability with low-impedance loads.

In addition to balanced analog inputs and throughputs that are permanently
installed on the rear panel, the TXn series amplifiers feature a Yamaha
mini-YGDAI standard card slot that comes supplied with an AES/EBU I/O card
for digital input and throughput. The analog and digital inputs can be used
independently, or signals can be applied to both and mixed or switched
automatically for emergency announcements, for example. The original
AES/EBU I/O card can be replaced with compatible Yamaha mini-YGDAI cards
that provide other digital or analog input/output formats, or with network cards
that allow full compatibility with CobraNet or EtherSound audio networks.
Flexible Input Configuration
NetworkAmp Manager II is a software application that lets you monitor,
manage, and control all TXn amplifier functions and DSP parameters. If you
will be combining TXn series amplifiers with Yamaha Tn, PC-1N, XP, XM and/or
XH series amplifiers, the available functions of those amplifiers can be
accessed as well if they are connected to the network via a Yamaha ACD1
Amplifier Controller Device.
The NetworkAmp Manager II software runs on Windows based computers. No
special drivers are required: simply connect your computer's Ethernet port to
a standard high-speed Ethernet hub, and then the hub ports can be directly
connected to the TXn amplifiers to be controlled/monitored. Once set up you
can use the software's efficient, intuitive graphical interface to remotely
monitor and control each device on the network.
In addition to comprehensive control and monitoring capability, the
NetworkAmp Manager II software also provides a number of features that
make managing and controlling large multi-amp systems easy and
efficient. You can name amps according to their function within your
system, group amplifiers for simultaneous control, and name the groups
for easy identification. For example, you might want to mute just the left
FOH high-frequency stack, or solo just the right FOH low-frequency stack
during a sound check. NetworkAmp Manager II makes this type of control
fast and easy.
There are also many advanced, flexible monitoring functions. NetworkAmp
Manager II can, for example, warn you when a parameter exceeds a
pre-defined voltage, wattage, temperature, or impedance (upper/lower)
value. This lets you keep track of all amplifiers in the system from a
central computer display in real time. Warnings are automatically logged
to an info file so it's easy to pinpoint and troubleshoot problems.
NetworkAmp Manager II for Comprehensive Central Control
Basic AES/EBU setup with analog backup
TXn amplifiers are fed digital signals via AES/EBU. TXn can be
configured to automatically switch to analog input when fault is
detected on the AES/EBU input.
Analog setup using TXn
and Tn amplifiers
This analog setup is supplied an analog
source signal directly from the mixing
console.
The TXn is driving subwoofers, with channels
A and B driven in parallel mode. The Tn
amplifiers are driving full range speakers,
receiving processed signal from the TXn
using the MY4-DA analog output card.
This example is a mono setup, as all channels
on the T5n amplifiers are receiving the same
processed signal from the TXn.
Optional ACD1 unit is required for remote
control and monitoring of the Tn amplifiers.

A digital PA system
Digital domain of your PA system is now expanded to keep signal digital right from
the input(AD8HR), the mixing console, and to the amplifiers(TXn). The
combination of AD8HR and NAI48ES may be used as a stagebox solution to send
signals to the FOH mixing console via EtherSound. Mixed signals are sent back to
the NAI48ES, and then on to the TXn amplifiers for processing and amplification.
NetworkAmp Manager II software is used for status monitoring and control,
connected to the amplifiers via standard Ethernet switches.
