        7. Speaker Configurations

        Anthem MRX 740 8K's and Yamaha RX-A670's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Anthem MRX 740 8K: 5.2.2 with internal amplifier and 5.2.4, 7.2.2 with addition of external 2 channel amplifier and 7.2.4 with addition of external 4 channel amplifier.
        • Yamaha RX-A670: 5.2.2 with internal amplifier.
        • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
        • Anthem MRX 740 8K: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier and 5.2.4, 7.2.2 with addition of external 2 channel amplifier and 7.2.4 with addition of external 4 channel amplifier.
        • Yamaha RX-A670: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
        • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
        • Anthem MRX 740 8K: 5.2, 7.2 with internal amplifier.
        • Yamaha RX-A670: 5.2, 7.2 with internal amplifier.
        • 2-ch Bi-Amp: Both models are 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.

        8. Immersive Audio Formats

        Dolby Atmos

        Anthem MRX 740 8K and Yamaha RX-A670 support Dolby Atmos.

        • 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.

        DTS:X

        Anthem MRX 740 8K and Yamaha RX-A670 support DTS:X.

        • 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 740 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.

        IMAX Enhanced

        Anthem MRX 740 8K 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.

        9. HDMI

        Anthem MRX 740 8K comes with 7 HDMI 2.1 inputs with 8K support. It has 3 outputs - 2 for MAIN and 1 for ZONE2.

        Yamaha RX-A670 comes with 4 HDMI inputs. It has 1 output.

        • 8K/60Hz and 4K/120Hz Passthrough on Anthem MRX 740 8K: All inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 video signal.
          4K/60Hz Passthrough on Yamaha RX-A670: All inputs pass up to 4K/60p 4:4:4 video signal.
        • 4K Upscaling on Yamaha RX-A670: It can upscale up to 4K 60p 4:4:4 from HDMI sources.
        • 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 Copy Protection: Anthem MRX 740 8K is HDCP 2.3 and Yamaha RX-A670 is HDCP 2.2 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 740 8K supports HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma.

        Yamaha RX-A670 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.


        Enhanced Audio Return Channel (eARC)

        Anthem MRX 740 8K and Yamaha RX-A670 support Audio Return Channel (ARC) which 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.


        Gaming Features

        Anthem MRX 740 8K supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.

        10. Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Anthem MRX 740 8K with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Anthem MRX 740 8K has 11.2 preamplifier outputs which allows you to connect the 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 receiver to power the rest. Also, Anthem MRX 740 8K has 11 channel processing but has only 7 channel amplifier, so it needs external amplifier connected to the analog pre-outs in order to reach its maximum speaker configuration.
        • Analog Line Inputs and Outputs: There are 4 pair of line inputs on both receivers for connecting sources with analog outputs. There is also 1 pair of line outputs on Anthem MRX 740 8K.
        • Digital Inputs and Outputs: 3 optical inputs, 1 optical output and 2 coaxial inputs are available on Anthem MRX 740 8K and 1 optical input and 2 coaxial inputs are available on Yamaha RX-A670 for digital audio connections.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
