Onkyo Sound is Emotion, Delivered

Drivers don’t judge sports cars on top speed alone. Acceleration, cornering, and braking are equally important. It’s the same with A/V receivers—wattage is an indication of loudness, not sound quality. The real test is current. High instantaneous current enhances speaker control for accurate and musical audio reproduction, from delicate piano passages to the full-throated roar of an orchestra. It’s the cornerstone of our amplification philosophy, and no one can match Onkyo for dynamic driving power. We don’t just translate signals into sound. We create sound you can feel. Engineered for Pure Exhilaration

High current is achieved with Wide Range Amplifier Technology (WRAT).

The design is built around a custom high-output transformer, customized 15,000 μF capacitors, and low-impedance copper bus-plates. Three-Stage Inverted Darlington Circuitry amplification features a discrete low-impedance output stage with high-current transistors for instantaneous power and extremely low distortion. The culmination of over 60 years’ audio engineering know-how, WRAT preserves the life and character of the master recording.

THX® Select2™ Plus for Reference-Level Sound

THX certification guarantees the same high volume, low-distortion sound you experience in a multiplex theater. Your TX-NR838 receiver passed more than 2,000 laboratory tests to ensure every aspect of audio performance meets THX standards for theater-reference sound. THX Select2 Plus is recommended for screen-to-seat viewing distances of three to four meters.

Pure Direct Analog Path for Interference-Free Hi-Fi Amplification

Pure Direct Analog Path mode brings higher fidelity to vinyl, SACD, or CD playback via your home theater. With this mode engaged, every digital circuit is physically shut down to prevent interference. Signals pass directly from the phono or analog audio inputs to the amplifiers and arrive at your front loudspeakers in pure analog form. The improvement in audio quality is quite dramatic, with the rich tonal character of your LPs shining through. This mode lets your A/V receiver double a dedicated all-analog hi-fi stereo amplifier.

Future-Ready with HDMI® 2.0

Imagine playing the latest blockbuster games on your Ultra HDTV at a breathtaking 60 frames per second with 7.2-channel Onkyo surround sound. With HDMI® terminals supporting 4K/60 Hz, this dream is now reality. Even if you’re not immediately upgrading to a 4K display, it’s great to know your receiver is ready when you are.

Supports HDCP 2.2 for 4K Streaming and TV

With Hollywood studios, satellite TV broadcasters, and video streaming services moving to HDCP 2.2 for future premium releases, it’s important that your A/V receiver can handle this new copy protection standard. The TX-NR838 is HDCP 2.2-compliant to handle the next generation of home entertainment.

Share Your HD Video Sources in Two Zones

Use the HDMI Sub Out to connect a second display in another room. This allows you to route 1080p content from the media players connected to your receiver and play it back on another TV with easy smartphone control.
