Amplifier

Anthem MRX 1140 8K Onkyo TX-RZ740

11 channel Class A/B Amplifier: Anthem MRX 1140 8K features 11 channel power amplifier with Class A/B design on Channels 1-5 and Class D design on the rest. It is rated at 140 W (8 Ω, 1 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

9 channel Amplifier: Onkyo TX-RZ740 features 9 channel power amplifier. It is rated at 100 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

  • Dynamic Audio Amplification: Onkyo TX-RZ740 features Dynamic Audio Amplification which is Onkyo’s amplification philosophy that focuses on capturing the energy and dynamism contained in the audio signal and reproducing it without loss. Audio signals are not static like a test tone, but rather a countless collection of constantly moving waves. While static measurements such as S/N ratio and Total Harmonic Distortion are important, Onkyo believes that excellent dynamic and transient response is the key to emotionally involving sound. Dynamism - the “life” in music - is achieved when the amp can respond to changes in the signal instantaneously, so notes start and stop naturally and the nuances in attack, decay, sustain, and release are voiced with conviction. Onkyo home theater receivers represent the culmination of almost 70 years’ experience in amplifier design. The unique elements of their amplification system comprise high-current, low-impedance architecture to accurately control large speaker cones while enabling instantaneous response to dynamic changes, and discrete wide-range amplifier circuit topology to eliminate phase shift for clear and accurate audio imaging.
  • Toroidal Transformer: Anthem MRX 1140 8K has a toroidal transformer which in general costs several times more than a regular C-core transformer and radiates less electromagnetic noise outside its donut shaped core.

THX Select™ (previously known as Select2) certification

Onkyo TX-RZ740 is THX Select™ (previously known as Select2) certified. This means that it is for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen.

  • THX™ Certification: THX™ Certification offers optimal performance, superior quality and seamless integration. THX works with partners from the ground up, so that certified products deliver professional quality audio-visual experiences right out of the box. They only certify the very best products with uncompromised quality, performance and consistency. They ensure that THX certified devices play well with lower performing devices and components. THX listening modes make the receiver to have one speaker set up for movies, music and games. They are tested for power output, bass management, signal-to-noise ratio and feature THX Loudness Plus, Boundary Gain Compensation, Timbre Matching and RE-EQ.
  • Power Output: Power output is tested to ensure the receiver accurately plays source material at THX Reference Level in every input and mode and at every sampling rate for all possible playback combinations selected by the listener.
  • Frequency Response: THX has strict requirements for frequency response to ensure that you hear all the details in high-resolution tracks, ensures dialog in movies, and vocals in music are clear while maintaining deep, impactful bass output that doesn’t overpower the listening experience.
  • Signal-to-Noise Ratio: THX tests the signal-to-noise ratio to ensure the unit is designed to have low noise performance with very little to no audible hiss from the speakers.
  • Bass Management: THX requires an 80Hz crossover point in the setup menu to ensure proper bass management in every THX Certified AVR. This setting confirms that the subwoofer handles low frequencies, freeing up the loudspeakers to handle mids and highs.
  • THX Loudness Plus™: THX Loudness Plus™ is a volume control technology featured in THX Certified Dominus, THX Certified Ultra and THX Certified Select AV Receivers, and preamplifiers that automatically adjusts the front-to-back speaker level relationship as you turn the volume down. With THX Loudness Plus, home theater audiences can now experience the rich details of surround sound at any volume level.
  • Boundary Gain Compensation: Sitting near a wall may result in increased acoustic levels at the lower frequencies. BGC corrects the way low frequency sound is perceived when seated near a wall. This results in a more accurate bass response.
  • Timbre Matching: Your ears hear different tonal qualities in sounds coming from different directions. Timbre Matching restores the frequency balance between your front and surround speakers ensuring seamless and smooth panning between the front to back of the room.
  • RE-EQ: Many movie soundtracks are mixed in studios for playback in large cinema auditoriums with an array of speakers. When played on home systems, they may appear abrasive and edgy. Re-EQ establishes a more accurate tonal balance when enjoying movies in your home.

Speaker Configurations

Anthem MRX 1140 8K's and Onkyo TX-RZ740's amplifiers can be assigned for different speaker configurations.

  • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
  • Anthem MRX 1140 8K: 5.2.2, 5.2.4, 5.2.6, 7.2.2, 7.2.4, 9.2.2 with internal amplifier and 7.2.6, 9.2.4 with addition of external 2 channel amplifier and 9.2.6 with addition of external 4 channel amplifier.
  • Onkyo TX-RZ740: 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:
  • Anthem MRX 1140 8K: This model supports DTS:X but not DTS:X Pro. Since DTS:X is limited with 11 channel processing some of the speaker configurations for Dolby Atmos are not supported here. The supported configurations are 5.2.2, 5.2.4, 5.2.6, 7.2.2, 7.2.4, 9.2.2 with internal amplifier.
  • Onkyo TX-RZ740: 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:
  • Anthem MRX 1140 8K: 5.2, 7.2, 9.2 with internal amplifier.
  • Onkyo TX-RZ740: 5.2, 7.2 with internal amplifier.
  • Front Wide Channel support: With the presence of two front wide speakers you can enhance the front surround stage. The following speaker configurations are available for front wide channels:
  • Anthem MRX 1140 8K: 9.2, 9.2.2, 9.2.4, 9.2.6.
  • Onkyo TX-RZ740: Does not support.
  • Bi-Amp: You can bi-amp Anthem MRX 1140 8K's and Onkyo TX-RZ740's front left and right speakers. 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

Anthem MRX 1140 8K and Onkyo TX-RZ740 support 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: Both models support 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: Onkyo TX-RZ740 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

Anthem MRX 1140 8K and Onkyo TX-RZ740 support DTS:X. A technique used in DTS:X is similar to the one used in Dolby Atmos. Instead of a fixed number of channels, DTS:X defines object locations from the listener in polar coordinates. An a/v receiver then dynamically renders sound according to the current speaker configuration. The speaker layout employed by DTS:X is the sum of Dolby Atmos and Auro-3D. It has standard 7.1 channel base layer, a 5 channel height layer above the base layer on the front and side walls, and 3 rows of speakers on the ceiling.

  • DTS Neural:X: Both models feature 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 Virtual:X: Anthem MRX 1140 8K supports DTS Virtual:X which bridges the gap between DTS:X codec and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. If you have a limited speaker setup you will miss a full immersive potential of your entertainment system. DTS Virtual:X adds height and surround audio effect to your system without adding height speakers. It works with multiple configurations and delivers immersive sound experience out of 5.1 or even 2.1 speaker layouts.
  • DTS Dialog Control: Both models have 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.

Enhanced Audio Return Channel (eARC)

Anthem MRX 1140 8K supports Audio Return Channel (ARC) feature allows the compatible TV to send audio signal to the a/v receiver through the same HDMI cable which is used to send audio and video signals to the TV. So one HDMI cable is used to transfer audio signal in both directions. New Enhanced ARC will support uncompressed audio formats such as Dolby Atmos, DTS:X, Dolby TrueHD and DTS HD Master Audio whereas the previous ARC could support only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.



Sound Processing

  • Compressed Music Enhancer: Onkyo TX-RZ740 features Compressed Music Enhancer which enhances the quality of the music files with lossy compression.
  • Advanced Music Optimizer: Compressed music enhancement in Onkyo TX-RZ740 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

Anthem MRX 1140 8K comes with Anthem Room Correction (ARC Genesis) and Onkyo TX-RZ740 comes with AccuEQ Advance with AccuReflex™ 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.

Video Section

    4K/60Hz Passthrough on Onkyo TX-RZ740: All inputs pass up to 4K/60p (RGB/YCbCr4:4:4) video signal.
  • 4K Upscaling on Onkyo TX-RZ740: It can upscale 1080p to 4K from HDMI and analog sources.
  • Analog To HDMI Upconversion: Onkyo TX-RZ740 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 both models).
  • HDCP 2.3 Copy Protection: Both receivers are 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)

Anthem MRX 1140 8K supports HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma.

Onkyo TX-RZ740 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.

  • 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.
  • HDR10+: HDR10+ is an HDR video technology that adds dynamic metadata to HDR10 source files. The dynamic metadata are used to adjust brightness levels on a scene-by-scene or even frame-by-frame basis. HDR10+ supports maximum of 10,000 nits peak brightness and 10-bit or more (up to 16-bit) color bit depth. It uses Samsung's dynamic metadata defined in SMPTE ST 2094-40.
  • Dolby Vision: Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. It covers content creation, distribution, and playback. Like HDR10+, it includes dynamic metadata that are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way specified by the content creator. Dolby Vision allows for a maximum resolution of 8K up to 12-bit color depth, maximum peak brightness of 10,000 nits and a color gamut up to Rec. 2020. It uses Dolby's proprietary dynamic metadata defined in SMPTE ST 2094-10.
  • Hybrid Log-Gamma (HLG): The Hybrid Log-Gamma (HLG) is a transfer function developed mainly for HDR live video feed and over-the-air broadcasts. It is an HDR format that uses BT.2020 color primaries and a bitdepth of 10-bit. It is backward compatible with the transfer function of SDR and is designed to be better-suited for television broadcasting, where the metadata required for other HDR formats is not backward compatible with non-HDR displays. HLG defines a non-linear optical-electro transfer function, in which the lower half of the signal values use a gamma curve and the upper half of the signal values use a logarithmic curve.

IMAX Enhanced

Anthem MRX 1140 8K and Onkyo TX-RZ740 are 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.
  • IMAX Enhanced Content: IMAX Enhanced studio partners have announced IMAX Enhanced versions of movies that exclusively feature IMAX's signature picture, sound and scale.
  • Picture: Stunning, ultra-vivid 4K HDR picture that utilizes the newest, proprietary Digital Media Remastering technology (DMR) developed by IMAX. DMR accurately reduces noise and grain under the filmmaker’s guidance to best optimize the content for a much higher-quality, higher-brightness display. Without this technology, high-dynamic range content can actually look worse than what was originally seen and intended by the filmmaker.
  • Sound: IMAX and DTS have partnered with award-winning Hollywood sound mixers leveraging DTS:X codec technology integrated in home audio equipment and select televisions to deliver an IMAX signature sound experience with deeper bass and more dynamic range.
  • Scale: Select IMAX Enhanced titles that were shot with IMAX-certified cameras or specially formatted for IMAX theatres feature its exclusive expanded aspect ratio, enabling viewers to see the full scale and scope of the picture on 4K HDR TVs.
  • Streaming Services: IMAX Enhanced is now available on the world’s biggest streaming services, including Disney+, BRAVIA CORE, Tencent, iQiyi and more.

Gaming Features

Anthem MRX 1140 8K supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.

  • Auto Low Latency Mode (ALLM): Auto Low Latency Mode enables the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity. When the receiver detects a gaming signal it will enter ALLM. The signal will also be sent to the TV causing it to automatically switch to a low-latency, low-lag mode for gaming. Some functions will not be available on the receiver and TV during ALLM.
  • Variable Refresh Rate (VRR): VRR enables a gaming source such as a console or computer to deliver video frames as fast as it can, which in many cases is slower than the normal static refresh rate. It allows the TV to adapt to certain frame rate which reduces or eliminates lag, judder and frame tearing for more fluid and better detailed gameplay.
  • Quick Frame Transport (QFT): QFT reduces latency for smoother no-lag gaming, and real-time interactive virtual reality. It transports each frame at a higher rate to decrease display latency, which is the amount of time between a frame being ready for transport in the GPU and that frame being completely displayed.
