We already listed pros and cons of each model. However, you may also find useful to look at their common strengths and weaknesses shown side-by-side.

Amplifier

• WRAT (Wide Range Amp Technology): Onkyo TX-NR545 and Onkyo TX-NR535 feature Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.

Speaker Configurations

Onkyo TX-NR545's and Onkyo TX-NR535's amplifiers can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
Onkyo TX-NR545: 5.2.2 with internal amplifier.
Onkyo TX-NR535: Not supported.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Onkyo TX-NR545: 5.2, 7.2 with internal amplifier.
Onkyo TX-NR535: 5.2 with internal amplifier.

Dolby Atmos

Onkyo TX-NR545 supports Dolby Atmos. It is a cinematic audio format in which sounds exist as individual entities, called audio objects. In Dolby Atmos, any sound can exist as an independent audio object, free of channel restrictions. They can be precisely placed and moved anywhere in your room, including overhead, to flow above and around you in three-dimensional space. Through the use of audio objects, overhead sound, and all the richness, clarity, and power of Dolby sound, Dolby Atmos turns your room into an amazing place for entertainment. The format supports up to 128 simultaneous independent audio objects in a mix for rich, realistic, and breathtaking sound. It recreates the director's original concept through descriptive metadata to provide customized playback for home theater and delivers sounds above you through overhead speakers, special upward-firing Dolby Atmos speakers, or a Dolby Atmos enabled sound bar.

• Dolby Surround Upmixer: Onkyo TX-NR545 supports Dolby Surround Upmixer. If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.

Sound Processing

• Compressed Music Enhancer: Onkyo TX-NR545 and Onkyo TX-NR535 feature Compressed Music Enhancer which enhances the quality of the music files with lossy compression.
Advanced Music Optimizer: Compressed music enhancement in Onkyo TX-NR545 and Onkyo TX-NR535 is done by Onkyo’s Advanced Music Optimizer. While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of high-frequency bit information is lost during the file-compression process. To counter this, Onkyo has designed the Advanced Music Optimizer to compensate for lost bit information and improve the quality of compressed audio signals. This results in a clearer and more expansive sound. Also included in this technology is a loudness correction feature that further improves the audio character of compressed files.

Room Calibration

Onkyo TX-NR545 comes with AccuEQ Advance and Onkyo TX-NR535 comes with AccuEQ room correction system.

• AccuEQ: First, AccuEQ detects the presence of speakers and evaluates the impedance of each. Next, it pinpoints their distance relative to the main listening position using the mic and sets suitable sound-pressure levels. Then it selects the optimal crossover frequency so that deeper bass rolls smoothly off to the subwoofer. Finally, AccuEQ performs frequency response equalization based on room-acoustic and speaker data collected via microphone. The sound-field is now tailored around the listening position, resulting in a more immersive and realistic in-film experience.

HDMI

Onkyo TX-NR545 and Onkyo TX-NR535 come with 6 HDMI inputs. It has 1 output.

• 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (RGB/YCbCr4:4:4/YCbCr4:2:2, 24 bit) video signal.
• Analog To HDMI Upconversion: Onkyo TX-NR545 supports analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
• HDCP 2.2.0 Copy Protection: Onkyo TX-NR545 is HDCP 2.2.0 compliant which is a requirement for 4K/HDR copy-protected content transmission.
• 3D Ready: Both receivers are able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Onkyo TX-NR545 supports HDR10

Onkyo TX-NR535 does not support HDR.

High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.

• HDR10: HDR10 uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports 10-bit color which corresponds to 1024 shades of the primary RGB colors. It is technically limited to a maximum of 10,000 nits peak brightness, however common HDR10 contents are mastered with peak brightness from 1,000 to 4,000 nits.

Audio

• Analog Line Inputs and Outputs: There are 8 pair of line inputs on Onkyo TX-NR545 and 7 pair of line inputs on Onkyo TX-NR535 for connecting sources with analog outputs. There are also 1 pair of line outputs on the receivers.
• Digital Inputs: 2 optical inputs and 1 coaxial input are available on Onkyo TX-NR545 and 1 optical input and 2 coaxial inputs are available on Onkyo TX-NR535 for digital audio connections.
• Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
