Onkyo unveils next-gen A/V receivers for 4K/60 Hz entertainment, universal hi-res audio streaming

Onkyo has unveiled the first of its next generation hi-fi/home cinema receivers. Fully networked with built-in Wi-Fi/Bluetooth, the new Spotify-equipped units are the world’s first AVRs to fully support upcoming Ultra HD 4K/60Hz video content (including the HDCP 2.2 DRM copy protection system) and gapless playback of high resolution audio.

Both units, TX-NR636 and TX-NR535, will be available in April.

Onkyo said it is paving the way for Ultra HD video playback at a “liquid-smooth” 60 frames per second.

The TX-NR636 is the first A/V receiver to support HDCP 2.2. This latest DRM copy-protection standard will be adopted for future premium 4K studio releases, 4K streaming via internet service providers, as well as for UHD terrestrial and satellite broadcasts. This content will be unplayable (or converted to standard definition) when passed through non-HDCP 2.2-compliant A/V receivers. Compatibility is therefore essential to users who plan to enjoy premium content in the future.

Powerful and Dynamic Sound Quality
Both the TX-NR535 and TX-NR636 are based on custom high-current architecture. A large, customized transformer, extra-large capacitors, and discrete low-distortion amplifiers are used, while the TX-NR636 adds Onkyo’s premier Three-Stage Inverted Darlington Circuitry on the front and centre channels. Both are meticulously tuned to deliver clear, full-bodied sound with a revealing midrange and fast, punchy bass, and are equally adept at steering DTS-HD Master Audio™ and Dolby TrueHD soundtracks through multiple channels or filling rooms with engaging two-channel sound.

Engineered for High-Resolution Audio
The free Onkyo remote app for iOS and Android devices easily locates and streams network-attached hi-res tracks via DLNA. Both receivers feature gapless playback of almost any high-resolution file format including 5.6 MHz DSD, Dolby TrueHD, 192 kHz/24-bit FLAC and WAV, and ALAC to 96 kHz and 24-bit depth.

Music stored on smartphone and tablet can be streamed via remote app and Wi-Fi to the home theatre, while users can browse and stream millions of available tracks on Spotify, Deezer, AUPEO! and TuneIn from within the app. Support for Spotify Connect will be added later this year via firmware update. This feature will enable subscribers to stream Spotify’s massive library of music to the receiver directly from the Spotify app via Wi-Fi.

Onboard Bluetooth is also included (no extra charge for an adapter) for convenient wireless listening, with Onkyo’s Advanced Music Optimizer DSP vastly improving the quality of compressed audio.

Dual 32-bit DSP Engines
On the TX-NR636, audio processing power has been upgraded from one to two 32-bit DSP engines for smooth and easy decoding of high-resolution formats such as Dolby TrueHD, DTS-HD Master Audio™, and 5.6 MHz DSD.

Simple Operation for People of All Ages
Everything from initial setup to everyday operation has been made simple and stress-free. Both models include Onkyo’s proprietary AccuEQ calibration system to optimise the surround sound to suit individual room acoustics and speaker setups. On-screen menus are overlaid via HDMI and adjustments can be made without interruption to the programme. All major control functions are also available via the remote streaming app, including cold power-up from Hybrid Standby.

Loaded with Useful Features and Connections
The TX-NR636 boasts six rear HDMI inputs, one front HDMI input supporting MHL™ and two HDMI outputs. It has an MM phono stage for turntable connection, and dedicated Powered Zone 2 terminals for multi-room audio. Users can also assign the surround back channels to bi-amp their front speakers. The receiver includes Dolby Pro Logic IIz 7.1-channel up-mixing, and converts low-resolution video (from legacy consoles or DVDs, for example) to 1080p/4K using industry-leading Qdeo™ upscaling technology.

The TX-NR535 has six rear 4K/60 Hz-capable HDMI inputs and one output, and can pass 4K/60 Hz content through to a compatible display. Both feature a USB input supporting most lossless audio formats stored on flash memory devices.

TX-NR636 4K/60Hz compatible 7.2-channel AVR with built-in Wi-Fi/Bluetooth and Dual 32-bit DSP engine, due late April, RSP £500.

TX-NR535 4K/60Hz compatible 5.2-channel AVR with built-in Wi-Fi/Bluetooth, due early April, £400.
