Features
Solid Power for Any Application
In touring applications that require the ability to drive large numbers of speakers, amp drive capability and power become extremely important criteria. Furthermore, since the entire system has to be set up, taken down, and transported for every show, the total number of amps required, and their total weight, has a significant influence on manpower and cost. While the Tn series power amps are all compact 2U-size units, they deliver remarkably high power: 2500 watts from the T5n, 2200 watts from the T4n, and 1900 watts from the T3n, stereo into 2 ohms. Tn series amplifiers are capable of driving line array or other large-scale speaker setups in systems that take up less space than ever before.
High Definition, Serious Impact
By applying the full gamut of technology, experience, and resources acquired through the development and production of industry-standard digital mixing consoles and signal processors, as well as extensive know-how gained through years of hall and installation system design, The Tn series amplifiers have been refined to unprecedented levels of performance and sound quality. Transparency across the entire audio spectrum is a basic requirement, but the Tn amplifiers go beyond the basics with extraordinary midrange presence and a low end that is huge and authoritative while maintaining maximum reproduction accuracy. This has been achieved not only through no-compromise parts selection and circuit design, but also through extensive vibration-reduction measures that effectively suppress internal vibration that can have a negative impact on sound quality. The heat sinks, for example, are solidly screwed to the chassis side panels at numerous points, but with special insulators that are designed to absorb vibration and chassis resonance that would otherwise interfere with optimum reproduction. The detailed work involved goes well beyond the normal definition of manufacturing and crosses over into the realm of craftsmanship.
Stable 2-ohm Drive Capability
Line array systems offer many benefits for large scale live sound applications, but because of the many speakers involved they normally need to be driven by a correspondingly large number of power amplifiers. The 2-ohm drive capability of the Tn series amplifiers easily drives multiple speakers in line array systems.Tn series are also an excellent choice for driving multiple parallel-connected Yamaha Installation Series speakers as well as multiple parallel-connected monitor speakers located on the stage. In order to provide stable low-impedance drive capability the Tn amplifiers employ 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 2 ohms.
