UHD / HDR eARC Adapter
This configuration enables 4K HDR display devices without native eARC support to output Dolby Vision, while allowing eARC-compatible sound systems to perfectly output Dolby Atmos.
This configuration allows you to expand the number of connected input devices.
This configuration allows you to expand the number of connected input devices.
If you want to control your Soundbar (e.g., Sonos ARC) volume using your TV remote:
- Ensure your TV supports HDMI-CEC (Consumer Electronics Control).
- Connect the HDMI OUT of the Arcana 2 to the eARC / ARC HDMI port on your TV.
- Change your TV's audio output setting from the internal TV speakers to the external sound system (ARC).
- Power cycle your TV by unplugging it for 10 seconds, then plug it back in.
Once these steps are completed, you will be able to control your Soundbar volume using your TV remote.
Arcana Configuration: MENU > AUDIO > TV ARC routing: on
Once configured, the TV's audio will be transmitted via ARC to the Arcana, and then output to your external sound system via eARC.
- Scroll the Wheel: Toggle options / Navigate menu.
- Press the Wheel: Enter MENU / Select.
- Every submenu ends with Back to return to the previous page.
Arcana Configuration: MENU > AUDIO, press the click wheel to select from the following options:
Audio is output exclusively via HDMI OUT to the TV/display; the Soundbar/audio system will remain silent.
Audio is output exclusively via eARC OUT to the Soundbar/audio system; the TV/display will remain silent.
Audio is output simultaneously via both HDMI OUT and eARC OUT; both devices will play audio.
- Arcana Configuration: MENU > AUDIO, select Auto, and press the click wheel to confirm.
- Select Sonos BEAM1 / ARC, and press the click wheel to change it to off.
- Select TV ARC routing, and press the click wheel to change it to on.
- If configured correctly, T1 will display HBR bitstream 192KHz when playing Dolby Atmos content (as shown in the diagram below).
- Arcana Configuration: MENU > LLDV → HDR, select On, and press the click wheel to confirm.
- Depending on your preference, select DCI-P3 or BT2020 for Primaries, then press the click wheel to confirm.
- Luminance can also be tailored to your needs by adjusting the Min Luminance and Max Luminance values.
- If configured correctly, IN will display LLDV, while T0 will display HDR (as shown in the diagram below).
Yes! It accepts inputs from any HDMI media player, supporting up to Atmos/TrueHD, and outputs to the Sonos Arc or any eARC-compatible sound system. It can also be used with AVRs/amplifiers, provided they support eARC to decode Dolby Atmos.
Arcana's input source supports the HDMI 2.0b specification with a maximum bandwidth of 18Gbps and resolutions up to 4K@60Hz. The output can be connected to HDMI 2.1 compliant TVs and displays.
Yes! It features ultra-low latency of less than 1ms, which is virtually imperceptible and ideal for gaming or real-time video processing.
If the DV Primaries are set to DCI-P3 and the LLDV signal is sent to a display device that lacks a DCI-P3 color profile, the colors will appear oversaturated, causing noticeable reddish skin tones on faces. The solution is to output BT2020 instead of DCI-P3.
Arcana Configuration: Go to MENU > LLDV -> HDR > Primaries, select BT2020, and press the click wheel to confirm.
Yes, absolutely! For instance, if you want to display Dolby Vision-supported games from your PS5 onto a 4K HDR TV or projector, Arcana is your ultimate solution. Arcana supports LLDV-to-HDR10 conversion, making it the perfect tool to elevate your picture quality!
Yes. Arcana supports 600MHz/18Gbps HDR, HDR10+, HLG, DV & LLDV, eARC, ALLM, and IMAX Enhanced.
No, it cannot natively. Standard ARC supports up to a maximum of 5.1 channels.
To output audio from your TV's internal apps, please refer to the [Installation & Configuration] > [Audio Output Settings for Internal TV Apps] section on this page. However, you can still achieve Dolby Atmos playback on your Soundbar or audio system from external media players by using Arcana to split and route the audio signal directly.
- If it displays "eARC/ ARC not active": Verify that both your playback devices and HDMI cables natively support eARC. Try power cycling or disconnecting and reconnecting the cables, then wait 5 seconds.
- If it displays "LPCM 48kHz 2.0ch/ 5.1ch/ 7.1ch 24bit": This indicates that your current source device is outputting a standard 2-channel, 5.1-channel, or 7.1-channel audio format rather than a Dolby Atmos bitstream.
Please inspect the HDMI cable connected to your Soundbar. To successfully transmit Dolby Atmos, you must use an Ultra High Speed HDMI 2.1 compliant cable that fully supports eARC functionality. Standard HDMI 2.0 cables do not have the bandwidth required for eARC, which will cause audio dropouts and parsing errors when handling high-bitrate Dolby Atmos signals.
