Overview
Not a soundbar or an all-in-one speaker system, this is a dedicated home theater receiver built around Dolby TrueHD and DTS-HD Master Audio decoding. It switches multiple HDMI sources to a single display while driving five main speakers and a subwoofer. Bluetooth streaming with aptX rounds out its wireless connections.
Full Dolby TrueHD and DTS-HD Master Audio decoding paired with HDMI switching makes this suited to a home theater built around a projector or TV with several sources. Its Bluetooth streaming and aptX support add a wireless option without needing a separate device. Buyers wanting height channels or built-in multi-room streaming will need to look at a higher tier receiver.
Who it's for
Home theater owners setting up a receiver-driven surround system with several HDMI sources fit this Onkyo well. Anyone streaming from a phone or laptop also benefits from its Bluetooth and aptX support. Buyers chasing Dolby Atmos height channels or multi-room streaming need a different model.
Pros and cons
- Dolby TrueHD and DTS-HD Master Audio decoding
- Four HDMI inputs with HDR and 4K passthrough
- Bluetooth streaming with aptX quality
- Backed by a two year warranty
- No listed height channel or Atmos support
- No built-in Wi-Fi, Bluetooth only for wireless
- Streaming apps limited to Pandora and Sirius XM
Performance notes
The receiver decodes Dolby TrueHD and DTS-HD Master Audio soundtracks internally, then routes the processed signal to five main channels and a subwoofer output. HDMI sources switch through the unit to a single display, carrying HDR and Deep Color metadata along with the video signal. Bluetooth handles wireless audio input using aptX for a more accurate compressed stream than standard Bluetooth codecs.
