Yamaha HTR 2071 5.1ch HD Audio Home Theater Receiver

Yamaha s exclusive low-range enhancement technology delivers richer bass than you expect from the speaker size while maintaining good localisation and sound balance even with compact front speakers. When a subwoofer is used, it improves the volume of the entire low range of the speaker system, not only the front speakers, but also enhancing the bass from the subwoofer. You'll enjoy video and music with sound that has exceptional power and presence. When music is encoded into a digitally compressed format like MP3, the frequency response suffers. Yamahas Compressed Music Enhancer employs sophisticated digital signal processing using exclusive algorithms to restore what was lost, so the music always sounds the way it should. The Subwoofer Trim control enhances the low frequencies by avoiding overlap with the front speaker output. This will result in a cleaner, more focused sound stage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is pushed toward the subwoofer. Subwoofer Trim takes care of this by separating the low subwoofer frequencies cleanly, thus stabilising the front stage while providing a well-balanced enhanced bass sound. Yamahas new ECO mode reduces power consumption by about 20%. It can be set from the top of the GUI menu. Auto Power Standby lets you save energy by selecting to turn off the power after 20 minutes, 2, 4, 8 or 12 hours.
