- What's Included
The TX-SR444 is powerful and versatile. It can pass 4K video to your display via HDMI® thanks to HDCP 2.2 compliance. Connection and setup is easy with the rear panel graphical hook-up instructions. AccuEQ room calibration adjusts the audio to suit your listening space and speaker system. There is also a useful Quick Setup button on the remote to adjust settings without pausing the program. With high-current Wide Range Amplification Technology under the hood, the TX-SR444 receiver delivers sound with power and clarity. With almost 70 years of audio engineering experience behind it, this Onkyo receiver provides the best possible audio performance with the latest features and highest build quality available for a very modest investment.
Supports Dolby Atmos® Up to 5.1.2 Channels
With Dolby Atmos, sound comes alive from all directions, including overhead. The format combines a channel-based audio bed with object-oriented sound to place and move specific effects around the room, creating a breathtakingly realistic and captivating sonic atmosphere.
Sound designers and artists are free to mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels.
Additionally, a new Dolby surround up-mixer allows for your current channel-based content (that has not been mixed for Dolby Atmos) to be expanded to fill the flexible speaker layouts of a Dolby Atmos system.
True Power from Discrete Amplifiers
Discrete Amps deliver high instantaneous current to increase speaker control for accurate and dynamic audio reproduction. This precise power is the cornerstone of Onkyo's amplification philosophy.
This gives the TX-SR444 massive power at 115 W/Ch (6 Ohms, 1 kHz, 0.9% THD, 1 Channel Driven, FTC) 65 W/Ch (8 Ohms, 20 Hz–20 kHz, 0.7% 2 Channels Driven, FTC).
HDMI 4 In / 1 Out: Ready for 4K UltraHD
The latest HDMI specification and HDCP 2.2 compatibility support the latest formats and technologies planned for Hollywood content. This latest HDMI spec offers a significant increase in bandwidth (up to 18Gbps) to support new features such as [email protected]/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution, and 4:4:4 color space.
Ready for Streaming Media Devices
The TX-SR444 has a USB port right next to the streaming media player HDMI input to conveniently power the device. Just plug in, log in to your subscription service and enjoy.
The TX-SR444 has Bluetooth technology built in. Pair up to ten compatible Bluetooth devices and stream high quality wireless audio using the built-in Bluetooth 2.1. The sound is virtually flawless.
AccuEQ conducts two measurements- one to set the level, distance, and crossover for ALL speakers, including the subwoofer, and a second measurement to eliminate standing waves. Choose to include or bypass EQ measurement for front, left, and right speakers, and choose to automatically or manually set the EQ. Further, you can save your own manual EQ settings into three available presets.
Classic Analog & Hi-Res Digital
This receiver is engineered for hi-res analog and digital audio. You can spin your classic vinyl and hear it in all its analog glory and stream your networked hi-res digital files. Both analog and digital audio sound their warmest and clearest. The TX-NR646 supports hi-res audio playback, gapless playback, and the ability to play DSD, Double DSD, FLAC and ALAC along with other Hi-Res formats.
Powered Zone 2 and Zone 2 Line-Outs
The TX-NR646 features Powered Zone 2 and Zone 2 line-outs. This lets you assign two channels to power audio in a room equipped with speakers. An existing hi-fi system in a third room can also be connected via the line-out, enabling the use of the A/V receiver as a pre-amp and audio server.
