Dolby Atmos® Multidimensional Sound

Onkyo is among the first to introduce the exciting Dolby Atmos surround-sound format to home theater environments. Dolby Atmos uses object-oriented mixing to layer independent audio elements through discrete channels, moving three-dimensional sound effects around the theater with astonishing realism. The format adapts to any home theater layout incorporating height channels for a more enveloping soundfield with extremely accurate directional and overhead effects.

HDCP 2.2 has been adopted for future premium 4K releases by Hollywood studios, satellite broadcasters, and internet video streaming services, and the TX-NR636 is ready. This receiver has paved the way for Ultra HD video playback.

Hi-Fi Power and Fidelity

WRAT (Wide Range Amplifier Technology) is all about current. Receivers need a lot of current not only to handle the sudden explosive actions scenes but also to reproduce the detail of quiet passages. We use a massive high-power transformer to drive discrete amps that help eliminate distortion and preserve the energy of music and movies. The TX-NR636 packs a colossal punch for movies but still retains the pure musicality you need for two-channel playback. Also, Phase-Matching Bass Enhancement optimizes low frequencies while preserving mid- range clarity. It counters phase shifting by synchronizing the timing of different frequencies. The result is deep, well- defined bass that won't blur vocals or strings.


Exclusive AccuEQ Room Calibration

Calibrating the sound to suit your room's acoustics is simple with AccuEQ. Once you've connected your speakers, plug-in the included mic and wait a few moments as the TX-NR636 measures things such as speaker distance, type, crossover, and output, taking into account any reflections from your walls and floor. The system is designed specifically to by-pass your front left and right speakers. The system then optimizes the frequency response of the remaining speakers so you can enjoy balanced surround sound regardless of room shape or furnishing while retaining the characteristics of your front left and right speakers for optimum enjoyment.
