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.
HDMI 6 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 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution, and 4:4:4 color space.
The TX-NR545 enables transmission of High Dynamic Range (HDR) formats, and provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image.
Bluetooth & Wi-Fi® with Pandora, Spotify, and AirPlay
The TX-NR545 has AirPlay, Wi-Fi and Bluetooth technologies built in. The free Onkyo Remote app puts a range of streaming options at your fingertips, from universal hi-res audio via network-attached devices to internet streaming services to music on your smartphone and tablet. Or pair up and enjoy whatever's playing on your Bluetooth-compatible device for huge cinematic sound.
This receiver comes loaded with Spotify, Pandora, SiriusXM Internet Radio, Slacker and TuneIn. You can select a station and search for music available on these services via the Onkyo Remote app on your phone. You'll never be short of your favorite music to enjoy.
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-NR545 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).
384 kHz/32-bit High Grade DAC
No matter what you're listening to, it will sound powerfully full, clean and clear. A premium-quality AK4458 digital-to-analog converter from Asahi Kasei implements unique low-distortion filtering technologies for clear sound, and unlocks the full potential of any audio format, including compressed, lossless, and hi-res audio (MP3, WMA, WMA Lossless, FLAC, WAV, OggVorbis, AAC, Apple Lossless, DSD 5.6 MHz, LPCM, and Dolby TrueHD).
Hi-Res Audio
This receiver is engineered for universal Hi-Res compatibility and ease of use. Use the remote app to locate your Hi-Res albums (including 5.6 MHz DSD playback) on PC or network-attached storage and bask in the clarity, depth, and detail of high-resolution music. The TX-NR545 supports 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-NR545 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.
