Audio Skills

The Onkyo TX-RZ730(B), with a total of 7 power amplifiers of 175 W each, provides an all-around sound experience. Integrated audio formats include – and now read carefully – DTS: X, DTS Neural:X, Dolby Atmos, Dolby TrueHD, Dolby Digital Plus, DTS-HD High Resolution Audio and DTS-HD Master Audio.
You don’t see such a range of different audio formats every day! Also on board is AccuEQ, a calibration method that optimizes the use of speakers to eliminate standing waves in the room.
As if that weren’t enough, the receiver also has what’s known as THX Certified Select. In other words, this certificate allows to guarantee a certain sound performance for a sufficiently large room area.


Connectivity – connections and interfaces

In addition to the usual options for establishing connections between the various components of a network, which include Bluetooth, HDMI and WLAN, the receiver also has Chromecast and FlareConnect. Conveniently, there is an HDMI port on the front of the device. A total of 6 more HDMI ports on the back complete the possibility to connect enough Blu-Ray players and laptops to the device at the same time. Chromcast is already integrated into the device. This is a technology provided by Google, which simplifies data transfer. With the help of Chromcast, media files can be transferred to the AV receiver.

The prerequisite for this is an existing Internet connection. For example, it is possible to display content from the Google web browser on the TV via the AV receiver. In contrast, FlareConnect is a multi-room application. In addition, this feature enables uncomplicated music playback via devices with FlareConnect compatibility. As a result, users experience flexibility and convenience to play their music when and where in the home. Additionally, the AVR includes the ability to easily dock Apple products thanks to built-in AirPlay.
