Creating a truly immersive entertainment experience in the home is no small task, but one that has driven the latest innovations incorporated in the Pioneer Elite VSX-21TXH receiver. At the core of the VSX-21TXH is the Direct Energy Class A/B amplifier to power a sonically dynamic multi-channel home theater. Connect a Pioneer Blu-ray Disc player to the Elite VSX-21TXH and lose yourself in the latest movie in a stunning 1080p picture complemented by a Dolby TrueHD or DTS-HD Master audio soundtrack. If you are enjoying your current DVD library, the VSX-21TXH will enhance the multi-channel soundtrack with the Pioneer-exclusive Advanced Sound Retriever-Multi (ASR) technology so the sound will be more robust in the larger 5.1 channel system. And if you are watching broadcast television, the proprietary Auto Level Control-Multi (ALC) will monitor and maintain the volume at a consistent level so commercials wont suddenly blast significantly more loudly than your favorite TV show.
