Lose yourself in movies and music Looking to take your home theater to the next level? Match yamaha's aventage rx-a870 to a 4k blu-ray player and you can enjoy the same video content in crystal-clear ultra hd on up to two compatible displays — perfect if you have both a tv and a video projector. Dolby atmos and dts:x bring movie soundtracks to life with incredible realism. Music lovers will appreciate this receiver's ability to play different high-resolution audio formats through the front-panel usb port or from a networked computer. And if you're into vinyl, a phono input provides an easy connection for your turntable. The aventage difference For their aventage-series receivers, yamaha uses custom-designed parts with anti-resonance technology to reduce distortion caused by vibration. A rigid h-shaped frame adds stability to cut out chassis vibration almost completely. A specially designed fifth foot at the center of the receiver's base dampens internal and external vibrations, and an aluminum front panel further reduces resonance to maximize sound quality. The rx-a870's meticulous construction, symmetrical amplifier layout, and low-jitter digital circuitry all work together to give you accurate sound with precise stereo imaging and a wide, natural soundstage. Loads of wireless listening options Built-in support for streaming services like spotify®, tidal, and pandora® lets you play and control your favorite music directly through the receiver. Apple® airplay® lets you stream from a compatible ios® device, and bluetooth adds even more streaming flexibility. You can even stream audio from the receiver to a set of bluetooth headphones — great for late-night listening. Musiccast lets you choose how to listen Setting up a whole home wireless music system has never been easier. This receiver's built-in musiccast technology lets you add audio playback in up to nine additional rooms with compatible yamaha wireless speakers and sound bars. Musiccast lets you stream music from your personal collection, internet radio, and streaming services. You can also play bluetooth sources, sound from your tv, and even cds and vinyl. The free musiccast controller app makes it easy to access your music and control what you have playing in different rooms. Flexible speaker connections for a custom sound system The rx-a870 has outputs for nine speakers, giving you a few different configuration options. You can set up a standard 7.2-channel surround sound system or a 5.1.2 dolby atmos system, and use the extra two speaker outputs to power a pair of speakers in a second room. That way, you can enjoy stereo music in zone 2 while others watch tv in the main room. When zone 2 is powered on, yamaha's intelligent amp assign feature automatically redirects the power for the two surround back channels — or the front height channels, depending on your configuration — to your stereo setup in zone 2, giving you five-channel surround sound in the living room. If you're happy with a simple 5.2-channel surround sound system, you can also use one of the extra sets of speaker outputs to bi-amp your front speakers for more powerful sound.
