Yamaha RX-A840 7.2 Channel AV Receiver Details

AVENTAGE AV Receivers : Designed to Deliver the Highest Levels of Audio Performance
The AVENTAGE line of high-performance AV receivers is based on the audio design concept of providing a massive, full-bodied sound for movie sound effects and the accurate reproduction of music sources. Every AVENTAGE model has the ability to reproduce the most subtle details of high-definition sound, so that listeners can enjoy a truly high-class sound studio experience at home.

Total Purity Concept for the Finest Sound Quality
The Total Purity Concept encompasses high drive amp technology, high purity preamplification, anti-vibration technology and independent pure power supplies. All models have a fully discrete power amplifier that helps to minimize distortion. They also adopt independent pure power supplies, allowing dedicated power supplies for the analog and digital circuitry to prevent digital noise from affecting analog circuitry. The anti-vibration heatsinks are designed to suppress vibration from transistors and sound pressure.

Anti-Resonance Technology Wedge Helps to Ensure that Vibrations Do Not Affect Sound Quality
The Anti-Resonance Technology Wedge (A.R.T. Wedge) is a fifth foot in the center of the unit. It dampens vibrations from the power transformer, power transistors and heatsinks, as well as vibrations that might be caused by the sound of the speakers.

Wi-Fi Built in and Wireless Direct Compatible for Easy Network
Wi-Fi built in capability allows wireless connection with your household wireless router, greatly simplifying system connections to enjoy network audio and music streaming services. If no Wi-Fi router is available, the unique Wireless Direct feature not only allows you to stream music directly from your smartphone or tablet via the AV Controller App's Music Player feature, AirPlay®, etc., but also control your receiver using the AV Controller App.

AirPlay Allows Streaming Music to AV Receiver
This AV receiver supports AirPlay, which means they can accept wireless music streaming from iPod touch®, iPhone or iPad, as well as from iTunes on Macs or PCs. This makes it easy to enjoy music from your mobile devices or computer on your home theater system. You can view metadata such as song title, artist name as well as album art* via AV receiver's on-screen display.

*Some models don't support album art display.

HTC Connect™ for Wireless Streaming
HTC Connect lets you stream music to your AV receiver wirelessly. You don't need a separate app because HTC Connect is built right into your HTC phone. Simply swiping the HTC phone screen starts music output to the AV receiver, from the HTC device's local music sources or third party music sources.
