The number of channels is equal to the number of possible connected speakers. The Onkyo TX-SR383 supports 7.2-channels sound, but Yamaha RX-A6A supports a 9.2-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 RX-A6A this value is 150/8 W/Ohm, and for the TX-SR383 it is 100/8 W/Ohm.

Audio features

After reviewing the audio features of each model, we can rate the TX-SR383 6 out of 10, and the RX-A6A - 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-A6A.

Pure Direct mode feeds sound directly to the amplifier and bypasses any DSP processing. Only Yamaha RX-A6A 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.

Connectivity

The connectivity of competitors in our comparison is markedly different, Onkyo TX-SR383 scored 6, and Yamaha RX-A6A scored 9 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, Onkyo TX-SR383 got 6 points, but Yamaha RX-A6A received 10 points.

Onkyo TX-SR383 is equipped with 4/1 HDMI inputs and outputs, and Yamaha RX-A6A has 7/3 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-A6A.

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 Onkyo TX-SR383 in the HDCP 2.2 version, and Yamaha RX-A6A has the HDCP 2.3 version.

Connecting a vinyl player or phonograph is possible using a Phono input which is represented by mini-jack or RCA connectors. Only the RX-A6A has a Phono interface.

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 TX-SR383 were rated 6 out of 10 against the 9 for the RX-A6A.

With the 4K pass-through feature, the AV receiver sends "native" 4K signals to a 4K TV from a video source without any processing. The TX-SR383 works with the 4K/60Hz video, and the RX-A6A has the 4K/120Hz.

The AV receiver passes "native" 8K signals from a video source to 8K TV without any encoding, with the 8k pass-through features. The 8K path-through is available on Yamaha RX-A6A.

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 Yamaha RX-A6A.

Additional features

In terms of evaluating additional features, the TX-SR383 got 4 points, but the RX-A6A has 10.

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 RX-A6A can be controlled by voice via Amazon Alexa, Google Assistant, Siri, Josh.AI. Yamaha RX-A6A 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

Onkyo TX-SR383 got 5 points for the multichannel surround sound and Yamaha RX-A6A got 8.

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. Yamaha RX-A6A 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 RX-A6A.

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. Yamaha RX-A6A has Auro-3D on its feature list.
