For more than 30 years Yamaha has been delivering top–quality power for professional audio applications. The recent Tn series amplifiers achieved new heights in power, efficiency, sonic quality, and low–impedance drive capability. And now the TXn series amplifiers bring together several industry–leading Yamaha technologies for the ultimate in power, processing, and networking performance.

Three new high-power amplifiers – The TX4n at 2,200 watts, the TX5n at 2,500 watts, and the TX6n at 3,000 watts per channel into 2 ohms — not only deliver extraordinary efficiency and stunning sound quality reliably into 2–ohm loads, but also offer sophisticated onboard DSP with a front-panel user interface that minimizes or eliminates the need for external equalizers, delays, and speaker processors. All models feature both analog and direct digital inputs, with automatic failsafe redundancy switching between digital and analog input. The input configuration can be changed as required using optional plug–in Yamaha mini–YGDAI interface cards. With the appropriate I/O cards these advanced amplifiers are fully compatible with CobraNet or EtherSound audio networks. The built–in Ethernet port can be connected to a computer running Yamaha's NetworkAmp Manager II software for comprehensive remote control and monitoring of individual amplifiers or groups.

The Yamaha name is associated with top-quality live sound for a number of very good reasons. Technology, experience, and resources acquired through years of product development and production as well as hall and installation design have made it possible to refine these outstanding power amplifiers to unprecedented levels of performance and sound quality. In addition to transparency across the entire audio spectrum, they deliver extraordinary midrange presence and a low end that is solid and authoritative without losing accuracy. No–compromise parts selection and innovative circuit design are major factors, but some new measures have also been implemented to suppress internal vibration that can degrade sound quality. The extraordinary attention to detail that has gone into these fine amplifiers results in sonic improvements that your ears — and those of your audience — will truly appreciate.

Yamaha's innovative EEEngine technology achieves a dramatic reduction in power consumption compared to conventional amplifiers, and this goes a long way towards alleviating the usual power supply quality and capacity problems encountered in large–scale live sound systems. Of course reduced power consumption also means less heat generation, significantly increasing part life and reliability. Fan speed is regulated by the CPU according to temperature levels of the amplifier, keeping the amplifier cool at all times while maintaining maximum efficiency. Only Yamaha EEEngine technology can deliver this level of high efficiency and stability with low–impedance loads.

Digital signal processing is an area in which Yamaha quality is legend. All three TXn models are capable of sophisticated 96–kHz signal processing with an extraordinary range of control and processing capabilities. In addition to basic amplifier control and status monitoring, there is enough DSP power built in to provide extensive speaker processing capabilities that will make external processors unnecessary in most 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 Yamahas NetworkAmp Manager II software running on a computer connected via Ethernet.

The TXn series amplifiers feature a Yamaha mini-YGDAI standard card slot that comes fitted with an AES/EBU I/O card for digital input and throughput. The amplifiers balanced analog inputs and throughputs are permanently installed on the rear panel. 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.
