Premium 4K picture

Enjoy your favourite movies or videos in crisp, sharp quality with Ultra HD 4K resolution and the latest HDMI 2.1. HDR technology also ensures high dynamic contrast. This makes the picture look more realistic, almost as if you’re actually seeing it in person.

Sound that draws you into the action

Dolby Audio (Dolby Digital, Dolby Digital+, Dolby Atmos) and optical output ensure that listening to music or watching movies and TV shows will be the best.

High performance for smooth operation

The high quality Amlogic S905X2-B 1.6GHz processor combined with 2GB of DDR4 RAM ensures that this multimedia centre won’t be overwhelmed even by demanding 4K content. The advantage is support for the H.265 (HEVC) codec, which reduces bitrate while maintaining image quality. So you get the same quality picture but save data.

Internet connection

The multimedia centre can be connected to the internet network via a classic Ethernet cable (RJ-45 connector) or via DualBand Wi-Fi. It supports both the slower 2.4 GHz and the faster 5 GHz.

Bult-in bluetooth

Bluetooth wireless technology lets you connect other devices such as a wireless mouse or keyboard, gamepad and more.

Mobile phone as a remote control

Surely everyone knows this – you sit comfortably on the sofa and find that the remote control is on the other side of the room. Few people will want to get up for him, but it doesn’t matter at all. The Chromecast built-in feature lets you control the MediaBox via the Android TV app via your mobile phone or tablet, which is usually always with everyone.
