Pioneer Elite Sc-55 Sc55 9.1-channel 3d Ready A/v Receiver

The SC-55's Class D3 9-channel amplifier is the most powerful amplifier of any multi-channel A/V receiver Pioneer has ever produced. Keeping the new audio formats of the Blu-ray Disc format in mind, Class D3 takes high-resolution multi-channel audio to a whole new level of immersive performance Rated at 140 watts x 9 channels is a lot of power but is not the whole story. Where the SC-55 really shows its unprecedented power output capability is when driving multi-channels simultaneously without losing significant per-channel output. Class A/B amplifiers simply cannot match the efficiency of Class D3 as their power output per channel diminishes rapidly when more channels are added to the work-load. This kind of unprecedented power capability allows you to appreciate the full dynamics from any media source in a way never before possible. The ability to drive more channels, simultaneously, means you can fully reproduce all of the dynamics and impact of high definition multi-channel Dolby and DTS soundtracks with up to 9 channels of the highest quality power output available today. Class Leading Power True-to-Life, High-Definition Audio with THX® Select 2 Plus Pioneer adds an extra dimension to the SC-55 by being the only multi-channel Class-D amplifier manufacturer to be awarded the coveted THX Select 2 Plus certification for the ultimate immersive surround sound experience for rooms up to 2000 square feet. This is particularly meaningful to home theater enthusiasts. Filmmakers mix their audio tracks at a "Reference Level" of 85dB. This level is the basis for THX certification engineering and performance. The SC-55 can produce this level with all channels driven, meeting and exceeding THX performance requirements while maintaining our signature sound. Of course, the SC-55 also supports high-definition audio formats like Dolby® TrueHD and DTS-HD® Master Audio, as well as new DTS NEO:X surround, providing a 3-D surround experience for up to 11.1 channels
