Features

The Onkyo TX-RZ740 AV receiver received an 11.2-channel preamp output and 11-channel internal signal processing. The power is 9 x 185 W (6 Ohms). Onkyo TX-RZ740 is equipped with decoders for all common surround sound formats, including Dolby Atmos and DTS: X. Based on this model, it is possible to build 3D systems in a configuration up to 5.2.4 without using external amplifiers. You can also create a virtual surround sound system and using Dolby Atmos Height Virtualizer technologies, the correct processing of IMAX content is also provided.

Design and build

Onkyo TX-RZ740 has a high-end audio circuit using proprietary technology of dynamic amplification (Dynamic Amplification), which operates in an extended frequency range. The output stages of the amplifiers are mounted on aluminum heat sinks with low resonance indices, and a custom transformer is used in the power supply unit of the AV receiver. The audio circuit of the AV receiver uses AKM4458 DACs, which provide accurate signal processing. To further eliminate the distortion of a low-level signal in the AV receiver provides proprietary technology VLSC.

Connectivity

The AV receiver has seven HDMI inputs and two outputs that support 4K video transmission with Dolby Vision and HDR10 technologies. A signal with 1080p parameters supplied to these inputs can be converted up to 4K resolution.

Setup

Fans of Sonos will be glad to know that the novelty via Wi-Fi can easily integrate with the devices of their favorite brand and become part of the Sonos Home Sound entertainment complex.

Pros and Cons

Pros

  • I enjoyed FlareConnect for multi-zone audio distribution to compatible components
  • It is very massive and equipped with high capacitance capacitors

Cons

  • In comparison with the previous model, the number of optical inputs has decreased, and the developers have sacrificed component and composite video inputs as the least relevant
