The Total Purity Concept is designed to encompass high-drive amp technology, high-purity preamplification, anti-vibration technology, and independent, pure power supplies. The receiver has fully discrete power amplifiers that help minimize distortion and adopts pure independent power supplies, allowing dedicated power supplies for the analog and digital circuitry to prevent digital noise from affecting analog circuitry. The anti-vibration heat sinks are designed to suppress vibration from transistors and sound pressure.

The Anti-Resonance Technology Wedge is a fifth foot in the center of the receiver. It is engineered to dampen vibrations from the power transformer, power transistors, and heat sinks, as well as vibrations that might be caused by the sound from the speakers.

The feet of the receiver feature a high-density structure that utilizes both straight and curved ribs to enhance strength and damping performance. This is designed to enhance installation stability and disperse chassis resonance, effectively eliminating external vibration. This helps to enhance low-range response, reduce resonance peaks in the mid- and high-range, and provide dynamic sound and accurate reproduction.

The AVENTAGE RX-A780 features an aluminum front panel to help shield sensitive circuitry from external noise and electronic radiation generated by dimmer switches, fluorescent lighting, video monitors, and the like. This helps ensure optimum sonic performance in a variety of installation environments.

This receiver can pass-through UHD video at 60 frames per second, as well as the HDR10, Dolby Vision, and HLG HDR formats for enhanced contrast and colors.

Built-in Wi-Fi allows you to connect the receiver to your wireless router, simplifying system connections for music streaming or enjoying networked audio from your computer or NAS. Bluetooth connectivity is also onboard, allowing you to stream audio from your compatible device into the receiver, or out from the receiver to another Bluetooth device, such as a pair of headphones.

These object-based sound technologies are designed to create realistic surround sound, positioning and moving individual sounds to nearly any virtual point in your room, including overhead.

YPAO-RSC analyzes the room acoustics with the included microphone to tune your system for optimal sound in your room. It employs RSC to correct early reflections for enhanced surround sound. Additionally, DSP Effect Normalization adjusts the room acoustics according to the reflected sounds of each CINEMA DSP program.

The free MusicCast app puts control of the receiver into the palm of your hand. Access your sources and streaming services, adjust volume and sound settings, and link with other MusicCast devices for simultaneous playback throughout your home.

With Alexa voice control integration, all you have to do is ask. Use any Alexa-enabled device, such as your Echo or Echo Dot, to control either the receiver by itself or multiple MusicCast devices throughout your home.

Explore a world of music with built-in streaming services. Syncing your playlists and likes from your smart device to the receiver and discovering new music becomes even easier with the receiver.

This feature, also known as Intelligent Amp Assign, allows you to enjoy stereo sound in a second room. When Zone 2 is turned on, the two surround back channels in a 7.1-channel system will be redirected to the two speakers in Zone 2, while still providing 5.1 channels of power to the main zone. This mitigates the need to switch speaker cables.

Enjoy music from your vinyl collection with your turntable through the dedicated phono input.

Combine the receiver with optional MusicCast wireless speakers and enjoy the convenience of a home theater with wireless surround speakers in a 5.1-channel setup.

Start with the AVENTAGE RX-A780 receiver in your home theater and expand to other rooms over time with optional MusicCast speakers, soundbars, or hi-fi gear. Stream your music and TV audio throughout the house over your existing Wi-Fi network.
