Bi-amping is the amplification of one speaker with two amplifiers. This amplification method has a positive effect on sound quality. Bi-amping is possible on the AVR-X6400H.

Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Denon AVR-X6400H has Pure Direct mode.

Most receivers now come with a microphone included. It is with the help of this microphone that the auto-calibration system functions, which adjusts the sound of the receiver to the room.

Speaker A/B switching allows you to change between the main and sub speaker set. Denon AVR-X6400H can work with the main and additional set of speakers - and switch between them.

Dolby Atmos' particularity is that this is the object-oriented sound format, that is, each audio signal object is independently sounded and connected to its spatial position. Denon AVR-X6400H can create 3D sound due to the Dolby Atmos support.

DTS:X is an algorithm used by the processor to create sound scenes, where sounds connected directly to objects rather than channels, and to determine the optimum sound output distribution in space. Surround sound with DTS:X is available on the AVR-X6400H.

Auro 3D gives a bit more versatility than Dolby Atmos or DTS:X and provides a hemispherical sound and enables a receiver to produce 3D sound stages. Denon AVR-X6400H has Auro-3D on its feature list.
