An overview of Denon AVRS530BT and Pioneer SC-LX502 will help us understand the many features that the devices are equipped with. According to the results of our review, Denon AVRS530BT received 4.3 points out of 10 possible, and Pioneer SC-LX502 was rated 8.1 points. Both AV receivers were introduced in 2017. And as a result of the review, it becomes clear that AVRS530BT is inferior in audio processing features to SC-LX502.
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 AVRS530BT 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 AVRS530BT it is 70/8 W/Ohm.
|Stereo power (RMS), W/Ohm||70/8, 90/6||120/8, 225/6|
|Output impedance, Ohm||8, 6||8, 6|
|THD in stereo, %||0.08||0.08|
After reviewing the audio features of each model, we can rate the AVRS530BT 5 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.
Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Pioneer SC-LX502 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.
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.

Denon AVRS530BT 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.
