Main advantages Denon AVR-S640H over Pioneer SC-LX502

Main advantages Pioneer SC-LX502 over Denon AVR-S640H

Amplifiers

For the built-in amplifier, the devices received different marks - 6 and 8, respectively, on a 10-point scale.

The number of channels is equal to the number of possible connected speakers. The Denon AVR-S640H supports 5.2-channels sound, but Pioneer SC-LX502 supports a 7.2-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 SC-LX502 this value is 120/8 W/Ohm, and for the AVR-S640H it is 75/8 W/Ohm.

Audio features

After reviewing the audio features of each model, we can rate the AVR-S640H 6 out of 10, and the SC-LX502 - 10.

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 SC-LX502.

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. Pioneer SC-LX502 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-S640H scored 7, and Pioneer SC-LX502 scored 8 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-S640H got 6 points, but Pioneer SC-LX502 received 8 points.

Denon AVR-S640H is equipped with 5/1 HDMI inputs and outputs, and Pioneer SC-LX502 has 7/2 HDMI inputs and outputs.

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-S640H were rated 6 out of 10 against the 10 for the SC-LX502.

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 with Pioneer SC-LX502.

Additional features

In terms of evaluating additional features, the AVR-S640H got 10 points, but the SC-LX502 has 7.

Voice control allows you to control the basic functions of the receiver through a smartphone, smart speaker or using the microphone that comes with the kit. The AVR-S640H can be controlled by voice via Amazon Alexa, Google Assistant, Siri, Josh.AI. Only the Denon AVR-S640H has the ECO mode.

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-S640H got 5 points for the multichannel surround sound and Pioneer SC-LX502 got 7.

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. Pioneer SC-LX502 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 SC-LX502.
