Onkyo quality meets high-performance, highly affordable digital home theater! When you take the giant step up to 5.1-channel discrete Dolby® Digital or DTS sound, you experience new realms of sonic realism, impact, and three-dimensionality. And who better to take you there than Onkyo? Oversized internal components, high-current power, and anti-resonant chassis design is never more critical than when Dolby Digital's dynamic peaks start rocking your home theater. For today's (and tomorrow's) intense digital soundtracks and music, quality of amplification is a big issue. Not only does the TX-DS484 give you 55 high-current watts x 5, but it features Onkyo's Wide Range Amplifier Technology to maximize signal accuracy with high-resolution sources.
