The number of channels is equal to the number of possible connected speakers. The Onkyo TX-RZ50 supports 9.2-channels sound, but Denon AVR-S670H 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 TX-RZ50 this value is 120/8 W/Ohm, and for the AVR-S670H it is 75/8 W/Ohm.

Audio features

After reviewing the audio features of each model, we can rate the TX-RZ50 9 out of 10, and the AVR-S670H - 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 TX-RZ50.

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-RZ50 scored 9, and Denon AVR-S670H scored 7 out of 10.

Multichannel surround

For the ability to create multichannel surround sound, each of the receivers received 8 points out of 10.

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. Onkyo TX-RZ50 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 TX-RZ50.

IMAX Enhanced is a licensing and certification program under which home theater devices deliver crisp 4K HDR pictures and powerful sound as it was designed by the IMAX engineers. Only the TX-RZ50 licensed by IMAX.
