Onkyo Launches Two New Dolby Atmos And DTS:X AV Receivers

February 6, 2019

Onkyo has launched two new Dolby Atmos and DTS:X enabled A/V receivers, the 5.2-ch TX-SR393 (155W/Ch) and 7.2-ch TX-SR494 (160W/Ch).

Dolby Atmos and DTS:X soundtracks are mixed in a 3D domain. Metadata transposes sound origins within the scene to their corresponding positions in the listening space, tracking effects vertically and horizontally and placing sounds all around the audience.

Dolby Atmos and DTS:X formats adapt to any speaker configuration. The new Onkyo TX-SR393 offers a space-saving 3.2.2-ch solution for native Dolby Atmos and DTS:X, while the TX-SR494 expands object-based audio playback through 5.2.2 channels. Dolby Surround and DTS Neural:X upmixing technologies remap legacy soundtracks for playback through any speaker layout, including those with height channels, for more spatially realistic sound. While 3D sound virtualisation creates a spatial sound-field from as few as 2.1 channels, the TX-SR393 offers real 5.2-ch or 3.2.2-ch surround-sound and the TX-SR494 real 7.2-ch, 5.2.2-ch, or 5.2-ch surround-sound, the latter with either Front L/R Bi-Amping or Powered Zone B audio distribution.

Both receivers feature four HDMI inputs and one ARC-enabled output with pass-through support for 4K/60p and HDR (Dolby Vision, HDR10, HLG, and BT.2020) along with the 4:4:4 colour sub-sampling. To confirm that content is playing as desired, the GUI includes an overlaid OSD information window. Input/output data can be called up to show details such HDR format, video resolution, frame-rate, and audio codec which can otherwise prove tricky to check in real time. AccuEQ Room Acoustic Calibration detects speaker presence, size, and distance from a measurement point, and sets sound-pressure levels. It selects the best subwoofer crossover and EQ’s all speakers. AccuReflex technology optimises 3D audio reproduction through Dolby Atmos-enabled speakers. It resolves phase-shift that arises from path differences between directional and non-directional sounds.

Onkyo TX-SR393 3.2.2-ch A/V receiver with Dolby Atmos and DTS:X – £349.99. Onkyo TX-SR494 5.2.2-ch A/V receiver with Dolby Atmos and DTS:X – £449.99. Both available in March 2019 in black or silver.
