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 only on the RX-V4A.

Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Yamaha RX-V4A 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.

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-S660H 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-S660H.
