Once in a blue moon, something so innovative comes along that it obliterates your preconceptions about what is possible. For example, whoever thought you could say "home theater" and "future proof" in the same sentence? Well, Onkyo did. As a matter of fact, our engineers said it in one word–TX-DS989. You'll find this revolutionary 7-channel THX Surround EX receiver has features and technologies found in no other receiver, regardless of price. In fact, it's so state of the art, some industry analysts are calling it "over-engineered." We tend to agree. The TX-DS989–a new receiver for a new age in home theater.

WRAT (Wide Range Amplifier Technology)
Impact and sound purity that conventional receivers can't match, from three distinct advantages: 1. Low negative feedback design; 2. Elimination of ground-potential fluctuations; 3. High instantaneous current capability.

Less than half the typical amount of attenuation is needed, so signals never come close to the noise floor.

More About this Feature
Audiophile-Grade Parts
The massive troidal power transformer, with secondary windings and independent ground connections to isolate each channel from crosstalk and AC-line linterfaces, is the kind you find only in high-end audio equipment. Huge custom-designed Audio Tuned Reference capacitors give you greater power delivery at low frequencies, plus tremendous continuous power reserves during the most dynamic sound effects and musical surges. For hi-fi purists, large multi-emitter output transistors provide faster switching speed, which translates into a wider dynamic range.

THX Ultra and THX Ultra2 offer the highest level of THX quality assurance. THX Ultra was designed for use in a 2000+ ft3 room, and guarantees superior performance and accurate reproduction of the movie theater experience in the home. The updated version, THX Ultra2, provides 7.1-channel playback of any 5.1 multi-channel program; video switching for all wide-bandwidth sources (including HDTV and progressive scan DVD) without picture degradation; and THX Games Mode to faithfully reproduce the sound content of video games.

Decodes the additional matrix-encoded channel from Dolby Digital Surround EX and DTS-ES Matrix 6.1-encoded DVDs, and divides it into two separate surround back channels for incredibly realistic 360 degree surround sound effects and precise sound location.

Dolby Digital EX creates 6 full-bandwidth output channels from 5.1-channel sources. This is done using a matrix decoder that delivers 3 surround channels from the 2 in the original recording.

There are two DTS-ES(Extended Surround) formats: DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1. The DTS;-ES Discrete 6.1 format is, as the name implies, a 6.1-channel system with a discrete back surround channel, while DTS-ES Matrix 6.1, like Dolby Digital Surround EX, provides a matrix-encoded back surround channel. There's also DTS Neo:6, which derives a 6-channel surround output from a stereo soundtrack, and regular DTS, which, like Dolby Digital, is a discrete 5.1-channel system, but which uses less compression than Dolby Digital.

While WRAT was originally developed for our high-end amplifiers to handle the sonic demands of such high-resolution formats as DVD-Audio and Super Audio CD, it also provides an improved dynamic S/N ratio and better delivery of momentary power peaks from all software, including regular CDs and DVDs.
1) Using an innovative low NFB design that virtually eliminates the influence of counter-electromagnetic force from the speakers.

2) Eliminating ground-potential fluctuations that could adversely affect the signal.

3) Delivering high instantaneous current–enough solid, clean power to effortlessly drive even difficult low-impedance loads. Just what’s needed to handle today’s home-theater speaker systems.

The result is movie-theater impact and sound purity that conventional receivers simply cannot match.
