    5. Amplifier

    7 channel Class G Amplifier

    Arcam HDA AVR31 features 7 channel power amplifier with Class G design. It is rated at 120 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

    • Toroidal Transformer: Arcam HDA AVR31 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.

    6. Speaker Configurations

    Arcam HDA AVR31's 7 channel amplifier can be assigned for different speaker configurations.

    • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
    • 5.2.2 with internal amplifier.
    • 5.2.4, 7.2.2 with addition of external 2 channel amplifier.
    • 5.2.6, 7.2.4, 9.2.2 with addition of external 4 channel amplifier.
    • 7.2.6, 9.2.4 with addition of external 6 channel amplifier.
    • 9.2.6 with addition of external 8 channel amplifier.
    • DTS:X Configurations: DTS:X is limited with 11 channel processing, so some of the speaker configurations for Dolby Atmos are not supported here:
    • 5.2.2 with internal amplifier.
    • 5.2.4, 7.2.2 with addition of external 2 channel amplifier.
    • 5.2.6, 7.2.4, 9.2.2 with addition of external 4 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.
    • 9.2 with addition of external 2 channel amplifier.
    • Front Wide Channel support: Arcam HDA AVR31 supports front wide channels. 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 - 9.2, 9.2.2, 9.2.4, 9.2.6.
    • 2-ch Bi-Amp: Arcam HDA AVR31 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.

    7. Immersive Audio Formats

    Dolby Atmos

    Arcam HDA AVR31 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

    Arcam HDA AVR31 supports DTS:X with Neural:X and Virtual:X.

    • No support of DTS:X Pro: Arcam HDA AVR31 does not support DTS:X Pro. So even though the receiver is capable of 15.2 channel processing it will be limited with 11.2.
    • 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.
    • Virtual:X 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: 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

    Arcam HDA AVR31 supports Auro-3D. It is an immersive 3D audio format developed by the Belgium-based company Auro Technologies.

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

    IMAX Enhanced

    Arcam HDA AVR31 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.

    8. HDMI 2.1

    Arcam HDA AVR31 features 7 HDMI 2.1 inputs with 8K support. It has 3 outputs: 2 x 8K for MAIN and 1 x 4K for ZONE2.

    • 8K/60Hz and 4K/120Hz Passthrough: All inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 video signal.
    • 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: Arcam HDA AVR31 is able to pass 3D video through HDMI.

    HDR (High Dynamic Range)

    Arcam HDA AVR31 supports HDR (high dynamic range) video formats such as HDR10, 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.


    Enhanced Audio Return Channel (eARC)

    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.


    Gaming Features

    Arcam HDA AVR31 supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) for lag-free and smooth gaming.

    9. Room Calibration

    Arcam HDA AVR31 comes with Dirac Live™ room correction system and includes the calibration microphone.

    • Dirac Live: The interaction between your sound system and the physical layout of your room has a huge impact on sound quality. Dirac Live™ Room Correction applies state-of-the-art, patented algorithms to analyze and digitally reduce room impact and enhance speaker performance. Dirac Live delivers a larger sweet spot, accurate staging, clarity, voice intelligibility, and a deeper, tighter bass not otherwise possible. Fully tunable to your preference.

    10. Multi-zone Playback

    Arcam HDA AVR31 offers multi-zone playback which allows you to play different input sources in 2 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 5 channels will be left for main zone amplification.
    • HDMI Output: Arcam HDA AVR31 offers HDMI output for Zone 2. This means that it can send two different HDMI signals to two displays.
    • Audio Pre Output: If you have a dedicated power amplifier for Zone 2 you can connect it to the a/v receiver via pre outs and control volume from the a/v receiver.

    11. Inputs and Outputs

    Audio

    • Analog Pre-Outs: Arcam HDA AVR31 has 15.2 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, Arcam HDA AVR31 has 15 channel processing but has only 7 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 and Outputs: There are 7 line inputs and 1 line output for analog audio connection.
    • Digital Inputs and Outputs: 2 optical inputs, 1 optical output and 4 coaxial inputs are available for digital audio connection.
    • Headphone Output: There is a 3.5 mm (1/8") headphone output jack on the front panel.
