Let's make the Denon AVR-X4500H versus Yamaha RX-V385 comparison. According to the results of our review, Denon AVR-X4500H received 9.4 points out of 10 possible, and Yamaha RX-V385 was rated 5 points. Both AV receivers were introduced in 2018. After comparison, it will become clear that among these two devices, the AVR-X4500H is more suitable for the role of the heart of home theater system.
For the built-in amplifier, the devices received different marks - 9 and 5, respectively, on a 10-point scale.
The number of channels is equal to the number of possible connected speakers. The Denon AVR-X4500H supports 9.2-channels sound, but Yamaha RX-V385 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-X4500H this value is 165/6 W/Ohm, and for the RX-V385 it is 70/6 W/Ohm.
|Stereo power (RMS), W/Ohm||125/8, 165/6||70/6|
|Output impedance, Ohm||8, 6||6|
|THD in stereo, %||0.05||0.09|
After reviewing the audio features of each model, we can rate the AVR-X4500H 9 out of 10, and the RX-V385 - 6.
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 AVR-X4500H.
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-X4500H can work with the main and additional set of speakers - and switch between them.

Denon AVR-X4500H got 9 points for the multichannel surround sound and Yamaha RX-V385 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-X4500H 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-X4500H.
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. Only the Denon AVR-X4500H has Auro-3D on its feature list.
