5 channel Amplifier: Onkyo TX-NR525 features 5 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).	9 channel Class D3 Amplifier: Pioneer SC-LX704 features 9 channel power amplifier with Class D3 design. It is rated at 135 W (8 Ω, 1 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

• WRAT (Wide Range Amp Technology): Onkyo TX-NR525 features 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.

Bi-amp Capability

Onkyo TX-NR525's and Pioneer SC-LX704's amplifiers can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
Onkyo TX-NR525: Not supported.
Pioneer SC-LX704: 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4 with addition of external 2 channel amplifier.
• DTS:X Configurations: The following speaker configurations are supported for DTS:X:
Onkyo TX-NR525: Not supported.
Pioneer SC-LX704: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4 with addition of external 2 channel amplifier.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Onkyo TX-NR525: 5.2 with internal amplifier.
Pioneer SC-LX704: 5.2, 7.2 with internal amplifier.
• Bi-Amp: Pioneer SC-LX704 is able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

Dolby Atmos

Pioneer SC-LX704 supports Dolby Atmos.

• Dolby Surround Upmixer: Pioneer SC-LX704 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.
• Dolby Atmos Height Virtualization: Pioneer SC-LX704 supports Dolby Atmos Height Virtualization which is a digital signal processing solution that leverages Dolby's deep understanding of human audio perception to create the sensation of overhead sound from the listener-level speakers.

DTS:X

Pioneer SC-LX704 supports DTS:X.

• DTS Neural:X: Pioneer SC-LX704 features DTS Neural:X which is an advanced upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
• DTS Dialog Control: Pioneer SC-LX704 has DTS Dialog Control. This function adjusts the dialog levels during playback of the DTS:X stream. It allows you to separately increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.

IMAX Enhanced

Pioneer SC-LX704 is IMAX Enhanced certified. To qualify for IMAX Enhanced certification, 4K HDR televisions, projectors, sound bars, a/v receivers, loudspeakers, powered subwoofers and other premium home entertainment devices must meet carefully prescribed performance requirements established by IMAX, DTS and Hollywood's leading experts.

• What makes an IMAX Enhanced A/V receiver different from an A/V receiver with DTS:X technology? DTS:X technology is commonly found in most multi-channel A/V receivers on the market today. All IMAX Enhanced A/V receivers include DTS:X technology and deliver additional features, such as auto-sensing of IMAX Enhanced content, via IMAX Mode. IMAX Mode indicates that your A/V receiver supports fully immersive IMAX signature sound.

Onkyo TX-NR525 comes with 6 HDMI inputs. It has 1 output.

Pioneer SC-LX704 comes with 7 HDMI inputs. It has 3 outputs - 1 MAIN and 1 SUB and 1 ZONE 2.

• 4K/30Hz Passthrough on Onkyo TX-NR525: All inputs pass up to 4K/30p video signal.
  4K/60Hz Passthrough on Pioneer SC-LX704: All inputs pass up to 4K/60p (YCbCr 4:4:4) video signal.
• 4K Upscaling on Pioneer SC-LX704: It can upscale 1080p to 4K from HDMI and analog sources.
• Analog To HDMI Upconversion: Pioneer SC-LX704 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.
• BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35% (available on Pioneer SC-LX704 only).
• HDCP Copy Protection: Onkyo TX-NR525 is HDCP 2.2 and Pioneer SC-LX704 is HDCP 2.3 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-NR525 does not support HDR.

Pioneer SC-LX704 supports HDR10, Dolby Vision and Hybrid Log-Gamma. 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.
