Onkyo TX-RZ740's 9 channel amplifier can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
5.2.2, 5.2.4, 7.2.2 with internal amplifier.
7.2.4 with addition of external 2 channel amplifier.
• DTS:X Configurations: 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.
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:
5.2, 7.2 with internal amplifier.
• 2-ch Bi-Amp: Onkyo TX-RZ740 allows you 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

Onkyo TX-RZ740 supports Dolby Atmos with Surround Upmixer and Atmos Height Virtualization.

• 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.
• Atmos Height Virtualization 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

Onkyo TX-RZ740 supports DTS:X with Neural:X.

• Neural:X 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: 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

Onkyo TX-RZ740 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-RZ740 features 7 HDMI inputs. It has 2 outputs: 1 Main and 1 Sub/Zone2.

• 4K/60Hz Passthrough: All inputs pass up to 4K/60p (RGB/YCbCr4:4:4) video signal.
• 4K Upscaling: Onkyo TX-RZ740 can upscale 1080p to 4K from HDMI and analog sources.
• Analog To HDMI Upconversion: The a/v receiver supports video upconversion, so you can connect your analog Component and Composite video sources and Onkyo TX-RZ740 will output them 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%.
• HDCP 2.3 Copy Protection: All inputs and outputs are HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
• 3D Ready: Onkyo TX-RZ740 is able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Onkyo TX-RZ740 supports HDR (high dynamic range) video formats such as HDR10, Dolby Vision and Hybrid Log-Gamma via HDMI ports. 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.

Onkyo TX-RZ740 comes with AccuEQ Advance with AccuReflex™ room correction system and includes the calibration microphone.

• 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.

Onkyo TX-RZ740 offers multi-zone playback which allows you to play different input sources in 3 different rooms.

Zone 2

• Powered Zone 2: You can use the unit's 2 amplifier channels by connecting Zone 2 speakers directly to the speaker terminals. The remaining 7 channels will be left for main zone amplification.
• HDMI Output: Onkyo TX-RZ740 offers HDMI output for Zone 2. This means that it can send two different HDMI signals to two displays.
• Audio Pre/Line Output: If you have a dedicated amplifier for Zone 2 you can connect it to the a/v receiver via pre/line outs and use "pre out" option to control volume from the a/v receiver or use "line out" option - send fixed signal and then control volume on the Zone 2 amplifier.

Zone 3

• Powered Zone 3: You can use the unit's 2 amplifier channels by connecting Zone 3 speakers directly to the speaker terminals. The remaining 7 channels will be left for main zone amplification.
• Audio Pre/Line Output: If you have a dedicated amplifier for Zone 2 you can connect it to the a/v receiver via pre/line outs and use "pre out" option to control volume from the a/v receiver or use "line out" option - send fixed signal and then control volume on the Zone 3 amplifier.

Audio

• Phono Input: There is an MM phono input with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the a/v receiver.
• Analog Pre-Outs: Onkyo TX-RZ740 has 11.2 preamplifier outputs which allow you to connect the a/v receiver to the external power amplifier. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the a/v receiver to power the rest. Also, Onkyo TX-RZ740 has 11 channel processing but has only 9 channel amplifier, so it needs the external amplifier connected to the analog pre-outs in order to reach the maximum speaker configuration.
• Analog Line Inputs: There are 7 line inputs for analog audio connection.
• Digital Inputs: 1 optical input and 1 coaxial input are available for digital audio connection.
• Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel.

Video

• HDMI:
Inputs: 7 (1 front)   Outputs: 2 (1 Main, 1 Sub/Zone2)
8K Inputs: 0
• Composite Video: Connect you VCR, Laserdisc player and other old video equipment with composite video cables.
Inputs: 2   Outputs: 0
• Component Video: Component video connection gives you the higher quality video compared to the composite video connection. So in case your old DVD player and other equipment do not have an HDMI output but have Component video output use this connection over the composite one. Onkyo TX-RZ740 supports up to 480i/576i resolution on Component video connectors.
