TX-NR901 THX Select 7.1-Channel Digital Surround Receiver
 

Emotion: Something that used to be merely a reaction to what was on the screen, or to music or movie dialogue floating through the air. Onkyo emotion: A reaction you experience before you’ve even attached the first cable of the TX-NR901. Prepare to be impressed when you first lay eyes on this receiver. And remember to use at least two people to lift it out of the box—that's how heavy it is thanks to its rugged build, featuring a sturdy, anti-resonant chassis. Relief comes from the knowledge of having a receiver that gives you exclusive sound quality from high-grade components. Powerful and highly accurate 192 kHz/24-bit DACs and dual 32-bit DSP chips bring out the highest in sound accuracy from the latest sound formats. High-bandwidth inputs and outputs are ready to tackle the latest high-definition sources. Connection to compatible displays from a single component cable is facilitated through upconversion from composite and S-Video sources. Longing to liberate your music files from your computer or to unlock the door to a world of music via Internet radio? The convergence of home theater and home network manifests itself in Onkyo’s Net-Tune™ protocol, which makes the TX-NR901 part of the only lineup of A/V receivers to boast this ability. And most importantly, you have peace of mind in knowing that you have chosen a receiver ready to handle the technology and the ever-increasing demands of the movies and music of today—and tomorrow.
