Key Features

Affordable little brother of the new 8K line

This model is an excellent affordable choice for those who do not need 8K video support, but wants a powerful professional media player with other key features of the newest 8K line of Dune HD media players: top picture quality, Dolby Vision VS10 technology, full support for all formats of HD audio, advanced support for playback of Dolby Vision files, support for full menu in ISO images and disc structures, AFR both for video files playback and for Android apps, professional video settings, YouTube 4K HDR, AV1 video codec, 1Gbit Ethernet, Dual Band 2T2R Wi-Fi, USB 3.0. Main differences from Pro 8K Plus model: no support for 8K and 4Kp120, lesser CPU performance, 4GB RAM instead of 8GB, no Wi-FI 6, fixed PCM sample rate when playing music files.

Replacement for famous Real Vision 4K models

This model can be used as an affordable replacement for the discontinued Real Vision 4K and Real Vision 4K Plus models. This model has almost all features of Real Vision 4K models except support for the outdated BD3D technology, and except support for music playback with original PCM sample rate (use Pro 8K Plus model if you need this feature). Besides, this model also has various advantages over Real Vision 4K models: AV1 codec, more flexible video zoom possibilities, decoding of any HD audio formats to multichannel PCM, support for 20TB+ USB HDDs, bigger built-in 64GB storage space, newer Android 11, and other improvements.

AV1 video codec

The media player supports the new AV1 video codec, which helps to get up to 50% video quality improvement without increasing video bitrate (or requires up to 50% lesser bitrate for the same video quality). This new video codec is already used by YouTube and will be increasingly important for compatibility with various video services and content sources.

4 GB operating memory

This is 2x more than in the previous generation of the most affordable professional media players, and gives better performance for the most heavy apps.

64 GB flash memory

A giant storage space for the most heavy apps, for system needs (such as storage of movie posters), and for internal storage which can be used for any purpose. For example, you can store media files in the internal storage and even share them to the local network via the built-in SMB file server.

Dolby Vision and HDR10+

The media player supports not only HDR technology, but also the most latest and advanced Dolby Vision and HDR10+ technologies. In conventional HDR technology, the brightness range is set at the beginning of the film and does not change during the film, so completely dark and completely bright scenes may have insufficient detail. In the latest Dolby Vision and HDR10+ technologies, the brightness range can vary from frame to frame, so the maximum picture detail is provided even in scenes that contain only dark or only light elements.

Dolby Vision VS10 video processor

The advanced Dolby Vision VS10 video processing engine ensures maximum image quality when playing any type of content (SDR, HDR, Dolby Vision) with any type of video output signal (SDR, HDR, Dolby Vision). In particular, it improves the quality of conversion between Dolby Vision, HDR, and SDR. This gives benefits even when using the media player with TVs that do not support Dolby Vision, including Plasma TVs, and especially when using projectors.

Dolby Vision profile 7 FEL

The media player supports direct playback of Dolby Vision profile 7 FEL double-track and double-layer files. This is the most advanced Dolby Vision format. The media player plays video in this format using both tracks/layers. The important Dolby Vision information from the second track/layer (Dolby Vision RPU metadata) is transmitted to TV together with video data from the first track/layer. The passed video data uses 10-bit color depth - the maximum color depth supported by OLED-panels in OLED TVs, i.e. this fully uses the capabilities of OLED TVs. Combined with the full use of Dolby Vision metadata this gives an excellent Dolby Vision picture on the TV screen.

Widest support for Dolby Vision file formats

Dolby Vision is supported for all popular file formats (MKV, MP4, TS, M2TS, ISO, movie folder structure). All popular Dolby Vision profiles (P5, P7 MEL and FEL, P8) are supported. The media player supports the largest number of variations of Dolby Vision file formats of any other media player.

Playback of Dolby Vision ISO/folder structures

The media player supports direct playback of movie ISO/folder structures in Dolby Vision format (MEL and FEL). The extended Dolby Vision information is used and transmitted to the TV to improve the picture quality. This is possible due to the unique video playback and output engine created by Dune HD.

Full support for HD audio

The media player can output all formats of HD audio (up to Dolby TrueHD and DTS X) to HDMI in bitstream passthrough mode. Additionally, the media player can decode all formats of HD audio to multichannel PCM (up to 7.1 channels).

Entire case as a heatsink for super-efficient silent cooling

The media player implements the best passive cooling approach, which uses the entire metal case as a huge heatsink. Heat is very efficiently transferred from the processor directly to the metal case via a special heat transfer element.

Android 11

For Android applications, the media player uses a modern Android version 11. This increases system performance and gives improved compatibility with the newest Android apps.

Other key advantages over competitors

Best-in-class movie ISO/folder structure playback

Dune HD media players have the best-in-class support for playback of movie ISO/folder structures, including full support for disc menu, 4K, DV, HDR10+, HDR10, HD audio. Movie ISO/folder structures can be played from any source - local drive (USB) or network drive (SMB, NFS). A special engine helps to ensure smooth playback of the entire movie w/o any audio/video interruptions even when playing movies with complicated structure.

Automatic framerate/resolution switching

The media player can automatically switch output framerate and resolution to match the played content. This helps to ensure absolutely smooth video playback and use the best way for video resolution upscaling (resolution upscaling by the media player or by the TV).

Flicker-free framerate/resolution switching

Dune HD media players implement its own advanced flicker-free approach for automatic framerate and resolution switching, which performs video mode switching before the start of file playback (rather than after). Most other media players perform video mode switching after the start of file playback, which causes unpleasant flickering.

Multichannel DSD and other advanced music formats

You can play music in various advanced formats, including multichannel FLAC, WavPack, APE, ALAC and even multichannel Super Audio CD (SACD). SACD music files, encoded using the advanced DSD audio codec, are supported in all popular formats (ISO, DFF, DSF), including both stereo and multichannel files, including files which use the DST compression. Multichannel DSD files can be output to HDMI as multichannel PCM. Stereo DSD files can be output to HDMI and S/PDIF as stereo PCM.

Widevine L1 for premium video services

Support for Widevine Level 1 DRM (the most advanced DRM level) makes it possible to watch premium online video services with HD and Ultra HD video quality. Media players w/o Widevine Level 1 support can only output low quality (standard definition) video in many such services.

Optimized OS

Since the media player does not have Google Android TV certification, the operating system in the media player is optimized to eliminate the unneeded burdens and limitations. In particular, the media player does not create unneeded Android folders on connected HDDs, system performance is not decreased by Android indexing files on the connected HDDs, and so on.

Dune HD Android Playback Accelerator technology

This unique technology intellectually manages the resources of Android OS to minimize the influence of Android OS on the media playback engine and ensure smooth and high-quality video and audio playback.

Linux-based Dune HD OS

The media player runs a unique hybrid OS which consists of a Linux-based Dune HD OS (to ensure stable operation and smooth media playback) and Android OS (to support Android applications), which run simultaneously.

Dune HD ecosystem

Based on open Dune HD SDK and APIs, various TV-optimized applications, plugins, extensions, GUI skins, collection management solutions, integrations with home automation systems are available via official Dune Store, 3-party vendors, and from the huge user's community.

Dune HD UI

The famous Dune HD UI, developed and polished during more than 12 years, specially optimized for the use on TV screens and operation via a standard remote control, tuned for the best possible usability, makes it easy and convenient to use the media player.

Dune HD movies organizer and movies encyclopedia

“My Collection” function organizes a user's movie collection into a nice looking catalog. A comprehensive movies encyclopedia provides the information about hundreds of thousands of movies with detailed descriptions, posters, cross-links between movies and persons, trailers, direct links to online video services, etc. The advanced file browser automatically recognizes movies.

Dune HD mobile app

The unique Dune HD mobile app (Dune Control) for iOS and Android mobiles devices provides full access to all functions of Dune HD media player in a very convenient and powerful way. It fully replaces the standard IR remote control, allows browsing and choosing the media content directly on your mobile device (the menu shown on the mobile device mirrors the menu shown on the TV screen), and includes Now Playing section for convenient media playback control.

Smart home

The media player provides the powerful IP Control interface and has a lot of options for integration into Smart Home and Home Automation systems, such as Control4 and Crestron.

Proven history of software updates during a very long period

Dune HD is known for its reputation to listen to user's feedback and provide software updates for many years. For example, for some old models, software updates with additional functions have been provided for more than 10 years already. This is possible due to the unique "single code base" approach, which means that firmware for all Dune HD models is based on the same software (continuously developed and improved according to user's feedback).

Other key features

1 Gbit Ethernet

Ensures fast data transfer and smooth playback of high bitrate video when using a wired connection to the home network.

Built-in Bluetooth

The built-in Bluetooth interface allows you to easily connect various remote controls, wireless keyboards, mice, joysticks, audio speakers, headphones, headsets and other devices.

Bluetooth remote with microphone, IR learning and AirMouse.

The included Bluetooth remote controls the media player via a radio channel, includes a microphone (for voice search in applications which support it), and has IR learning function (allows you to configure the remote control to control not only a media player, but also a TV or other equipment). The AirMouse function allows convenient control of Android applications not optimized for controlling via a conventional remote.

IR control

The media player has the built-in IR receiver and can be controlled also by IR commands. This means you can use a 3-party programmable or learnable remote of your choice to control the media player, or integrate the media player with your smart home via IR. For example, you can integrate the media player with a smart speaker by using an IR emitter device controlled by the smart speaker.

Front panel display

During file playback, the display shows the current playback position. Also it can show the current time. Display mode can be adjusted in the menu.
