Onkyo upgrades its AV receiver lineup with 4K/60Hz-specified HDMI and gapless high-resolution network audio support as it launches the 5.2-channel TX-NR535 and the 7.2-channel TX-NR636.
Both AVRs include built-in wifi and Bluetooth for easier connectivity to audio sources, while the TX-NR636 is HDCP 2.2 compatible for future-proof 4K source playback.
Onkyo says the AVRs carry custom high-current architecture, with a "massive" transformer, extra-large capcitors and discrete low-distortion amplifiers to push DTS-HD Master Audio and Dolby TrueHD audio through multiple channels. The TX-NR636 adds 3-stage inverted Darlington circuitry on the front and centre channels.
Proprietary AccuEQ calibration handles surround sound optimisation as per individual room acoustics and speaker setups.
The TX-NR535 carries 6 rear 4K/60 Hz-capable HDMI inputs and 1 output. Meanwhile The TX-NR636 features 6 rear HDMI inputs, 1 front HDMI input (with MHL support) and 2 HDMI outputs, as well as an MM phono stage for turntable connection and dedicated Powered Zone 2 terminals for multi-room audio.
It also includes Dolby Pro Logic IIz 7.1-channel upmixing and low-resolution video upscaling via Qdeo technology.
The free Onkyo Remote App 2 handles streaming from mobile devices as well as Spotify, internet radio, Deezer, AUPEO! and TuneIn. A future firmware update will also add Spotify Connect support, allowing subscribers to stream Spotify music directly on the AVRs from the Spotify app via wifi.
