Onkyo TX-NR636

Most features you can expect from a modern AV receiver exist in the Onkyo TX-NR636 including built-in WiFi, home theater decoders (DTS, Dolby Digital, etc), Bluetooth, and HDMI ports.

You also get optical, coaxial, component video, and analog RCA jacks. There are more than enough ports to provide compatibility with almost all types audio video source/player in the market.

This AV receiver plays good selection of audio file format including WAV, FLAC, DSD, Double DSD, and ALAC up to 24-bit/192kHz quality and is MHL-compatible.

Apart from the usual, it supports 4K video processing which now starts to gain its popularity in the market. There are several truly modern features required for today’s audio necessities including Dolby Atmos and HDMI 2.0.

Onkyo TX-NR636 is one of the first few AV receivers to introduce Dolby Atmos. It is the latest invention from Dolby to add new dimension to home theater experience.

While the 5.1 and 7.1 schemes basically deliver sound all over the room, Atmos is able to create more interesting 3-dimensional effects. The sound is no longer creating a wall around the audience, but also above them.

HDMI 2.0 connectivity is provided to give better support to Ultra HD 4K which certainly requires more bandwidth. Another futuristic feature is HDCP 2.2, the latest type of copy protection to create more secure and stable connection between source and display for Ultra HD 4K.

Onkyo implements AccuEQ to analyze room condition, speaker size, and placement to calibrate sound processing for best possible output.

The package includes a small microphone which will be used as a reference point to deploy AccuEQ. You need to place it in front of the receiver to let it work.
