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

      Yamaha RX-A6A and Anthem MRX 1140 8K 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.
      • Dolby Atmos Height Virtualization: Yamaha RX-A6A 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

      Yamaha RX-A6A and Anthem MRX 1140 8K 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: Yamaha RX-A6A 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.

      Auro-3D

      Yamaha RX-A6A supports Auro-3D.

      • Auro-Matic upmixer: Auro-Matic upmixer takes non Auro-3D sound and upmixes to the current speaker configuration.

      IMAX Enhanced

      Anthem MRX 1140 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 2.1

      Yamaha RX-A6A comes with 7 HDMI 2.1 inputs with 8K support. It has 3 outputs - 2 for MAIN and 1 for ZONE2/4.

      Anthem MRX 1140 8K comes with 7 HDMI 2.1 inputs with 8K support. It has 3 outputs - 2 for MAIN and 1 for ZONE2.

      • 8K/60Hz and 4K/120Hz Passthrough: On both receivers all inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 video signal.
      • 4K Upscaling on Yamaha RX-A6A: It can upscale up to 4K 60p 4:4:4 from HDMI and analog sources.
      • Analog To HDMI Upconversion: Yamaha RX-A6A 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.
      • Quick Media Switching (QMS): With HDMI 2.1a, Quick Media Switching for movies and video uses the HDMI VRR mechanism to eliminate the blackout period when an HDMI Source device switches its video mode. As long as the resolution remains the same and only the frame rate changes, QMS will instantly switch between frame rates. QMS eliminates A/V blackouts by using VRR technology to change frame rates, allowing instant changes from 24Hz to 60Hz frame rate, and anywhere in-between. The viewer never sees blank screens and gets a seamless experience (available on Yamaha RX-A6A only).
      • 3D Ready: Both receivers are able to pass 3D video through HDMI.

      HDR (High Dynamic Range)

      Both receivers support HDR10, 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)

      Yamaha RX-A6A and Anthem MRX 1140 8K 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

      Both receivers support 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 Yamaha RX-A6A and Anthem MRX 1140 8K with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
      • Analog Pre-Outs: Yamaha RX-A6A has 11.2 and Anthem MRX 1140 8K has 15.2 preamplifier outputs which allow you to connect the receivers to the external power amplifiers. 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, Yamaha RX-A6A has 11 channel processing but has only 9 channel amplifier and Anthem MRX 1140 8K has 15 channel processing but has only 9 channel amplifier, so they need external amplifiers connected to their analog pre-outs in order to reach their maximum speaker configurations.
      • XLR Inputs and Outputs: There is one pair of XLR inputs on Yamaha RX-A6A. If your CD player, Blu-Ray player or other source have XLR outputs you can connect them to the receiver's XLR Inputs for higher quality balanced connection. Besides unbalanced RCA pre-outs Yamaha RX-A6A also has XLR outputs. In case your external power amplifier has XLR inputs you can use the balanced connection for higher audio quality.
      • Analog Line Inputs and Outputs: There are 5 pair of line inputs on Yamaha RX-A6A and 4 pair of line inputs on Anthem MRX 1140 8K for connecting sources with analog outputs. There is also 1 pair of line outputs on Anthem MRX 1140 8K.
      • Digital Inputs: 3 optical inputs and 2 coaxial inputs are available on Yamaha RX-A6A and 3 optical inputs, 1 optical output and 2 coaxial inputs are available on Anthem MRX 1140 8K for digital audio connections.
      • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
