Key Specs
- Number of Channels: 11.2 (The number of discrete channels of sound output. This can be a single number or multiple numbers separated by decimal(s). The first number is the primary, horizontally directed audio channels. The number after the first decimal, if applicable, is the number of subwoofer outputs or channels. The number after the second decimal, if applicable, is the number of height or atmospheric channels designed to immerse the listener by producing overhead sound effects.)
- Video Pass-through: 2160 (4K) (Devices with this feature allow video signals to travel from their source to a target device without alteration. For example, a receiver with 4K pass-through would allow 4K video signal from a Blu-ray player to pass to a target TV with surround sound; without the pass-through ability, the receiver would not allow both 4K video and surround sound to be transmitted simultaneously.)
- Works With: Amazon Alexa (Compatible with or able to be connected to other smart devices or applications.)
- Voice Assistant Built-in: Amazon Alexa (A digital assistant built into the device that uses voice commands to answer questions and control smart devices.)

- High Resolution Audio: true (Hear music the way musicians and sound technicians intended it to be heard. Products that support hi-res audio deliver audio signals with a dynamic range and bandwidth far greater than that of a standard CD so you'll be able to enjoy pure music with outstanding sound quality. The device supports high-resolution audio signals, which more closely resemble the quality of music as it was originally recorded, with more texture and detail than can be heard via typical music streaming services or CDs.)
- Number of Audio Zone Source Outputs: 4 (Multiple source outputs from the receiver mean different speakers are able to receive different sound sources from the receiver or preamp/processor. For every output, a different sound source can be accessed simultaneously in different zones. For example, two source outputs could be a streaming media player in one room and a Blu-ray player in another.)
- Surround Sound Supported: Auro 3D, DTS:X, Dolby Atmos (Surround sound systems use multiple audio channels and speakers to create an immersive sound experience for the listener. There are also various proprietary technologies that imitate this kind of sound via a device's built-in speakers or soundbar.)
- Maximum Sampling Rate Supported: 192 kHz (Generally, the higher the sampling rate, the greater the quality of audio and/or video.)
