Main advantages Denon AVR-X4500H over Denon AVR-S650H

Main advantages Denon AVR-S650H over Denon AVR-X4500H

Amplifiers

For the built-in amplifier, the devices received different marks - 9 and 6, 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 Denon AVR-S650H supports a 5.2-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 125/8 W/Ohm, and for the AVR-S650H it is 75/8 W/Ohm.

Audio features

After reviewing the audio features of each model, we can rate the AVR-X4500H 9 out of 10, and the AVR-S650H - 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.

Connectivity

The connectivity of competitors in our comparison is markedly different, Denon AVR-X4500H scored 8, and Denon AVR-S650H scored 7 out of 10.

Bluetooth connection is now one of the main communication protocols for the receiver's control or even music broadcasting.

Streaming services

Now music streaming services are gaining more and more popularity. They allow users to listen to millions of songs by subscription.

Extensive connections

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-X4500H got 10 points, but Denon AVR-S650H received 7 points.

Denon AVR-X4500H is equipped with 8/3 HDMI inputs and outputs, and Denon AVR-S650H has 5/1 HDMI inputs and outputs.

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-X4500H in the HDCP 2.2 version, and Denon AVR-S650H has the HDCP 2.3 version.

Video features

The AV receiver is the heart of the home theater. And in this case, support for all current video formats ensures the best user experience, so it is very important to consider this when choosing a device. Video features of the AVR-X4500H were rated 10 out of 10 against the 6 for the AVR-S650H.

Most of the AV receivers have a video scaling function, it is the process of reformatting the video signal to a higher resolution without losing the quality of the image. Upscaling the video signal resolution is possible only with Denon AVR-X4500H.

Additional features

In terms of evaluating additional features, both receivers received a score of 10 out of 10.

Multi-room

As the center of a home media system, each multichannel receiver has an additional set of terminals for connecting the second set of speakers to create additional audio space in Zone 2 or even Zone 3 where audio can have the separate source.

Multichannel surround

Denon AVR-X4500H got 9 points for the multichannel surround sound and Denon AVR-S650H 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.
