• 4K Ultra HD is a video resolution standard with a horizontal pixel count of 3840 and a vertical pixel count of 2160, commonly referred to as 4K. It is four times the resolution of traditional high-definition (HD) video, allowing for a clearer, more detailed, and more lifelike image.
• 4K Ultra HD is an advanced video technology that provides the main advantage of higher quality images. It can present more detail and depth and still maintain clarity on larger screens. This allows viewers to immerse themselves in the visual effects world and achieve a more realistic viewing experience.
• eARC stands for Enhanced Audio Return Channel, and it is a feature of the HDMI (High-Definition Multimedia Interface) protocol that allows for the transmission of high-quality audio signals between compatible devices.
• The purpose of eARC is to provide a more robust and efficient way to transmit audio signals, particularly for advanced audio formats like Dolby Atmos and DTS:X, which require more bandwidth than traditional audio formats. With eARC, the audio data can be transmitted in a more efficient manner, resulting in higher quality sound and fewer compatibility issues.

Connecting Instruction

1. Left and right speakers
   Front left and right speakers can create the overall soundstage. Place the speakers in front of the user at ear-listening level. Toe-in the speakers inwards and create an equilateral triangle between the user and the two speakers so that they meet to a point that goes behind the user. Then adjust the angle to find the position where the audio has better soundstage and imaging.

2. Center speaker
   The center speaker produces most of the dialogue and vocals and reinforces the sound effect of front left and right speakers. Place the center speaker under or above the display device and make sure it faces to the user at ear- listening level or at the same level as the front left and right speakers.

3. Subwoofer
   The subwoofer adds emotion and impact, and handles the bass in the sound field. The sound quality and volume of the subwoofer are closely related to the shape of your audio room and the listening position. In general, place the subwoofer in the front corner, or the one-third width of the room, or anywhere you feel the best sound.

4. Left and right surround speakers
   These speakers are used for precise positioning of sounds and to bring spatial sound effect from all directions. Place these speakers on the sides or slightly backward sides of the user at the height of about 60cm to 100cm above user’s ears. The same distance between the speaker and the user brings ideal sound quality.

5. Left and right rear surround speakers
   These speakers support you to enjoy best effect of Dolby HD and DTS HD by enhancing the surround sound and create a realistic immersive effect. Place these speakers in the back of the user at the height of 40cm to 100cm above user’s ears.

6. Left and right top front speakers
   Add another layer to create 3D sound effect which transports you with breakthrough, spatial and realistic audio experience and brings you a deeper connection to music and images.
