And as a result of the review, it becomes clear that RX-V485 is inferior in audio processing features to AVR-X2400H.
For the built-in amplifier, the devices received different marks - 8 and 6, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Denon AVR-X2400H supports 7.2-channels sound, but Yamaha RX-V485 supports a 5.1-channels configuration.
RMS stands for the actual power of the receiver. The higher this value, the louder the sound can be produced. The differences between the models in terms of RMS power are significant - for the AVR-X2400H this value is 95/8 W/Ohm, and for the RX-V485 it is 80/8 W/Ohm.
|Stereo power (RMS), W/Ohm||95/8, 125/6||80/8, 145/6|
|Output impedance, Ohm||8, 6||8, 6|
|THD in stereo, %||0.08||0.09|
After reviewing the audio features of each model, we can rate the AVR-X2400H 6 out of 10, and the RX-V485 - 9.
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 RX-V485.
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.

The presence of many connectors makes the receiver more versatile. But there are also narrowly targeted models, the number of connectors which are limited to a certain area of use. And when choosing their own receiver, users need to consider exactly your goals for using the receiver. For extensive connection, Denon AVR-X2400H got 7 points, but Yamaha RX-V485 received 8 points.
Denon AVR-X2400H is equipped with 8/2 HDMI inputs and outputs, and Yamaha RX-V485 has 4/1 HDMI inputs and outputs.
HDMI eARC is the next step in the development of audio return channel technology, which works in conjunction with HDMI 2.1. Using eARC provides the highest sound quality for home audio systems. HDMI eARC is available on Yamaha RX-V485.
The HDCP encryption protocol is now mandatory for most media devices. This security technology encrypts digital signals from one product to another. HDCP content-encryption protocol is present on Denon AVR-X2400H in the HDCP 2.2 version, and Yamaha RX-V485 has the HDCP 2.3 version.

Denon AVR-X2400H got 7 points for the multichannel surround sound and Yamaha RX-V485 got 5.
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-X2400H 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 only on the AVR-X2400H.
