1、HD Multimedia Interface: Supports 1 HD Multimedia Interface signal input and 1 HD Multimedia Interface signal output. It can support sound extraction and sound embedding function (sound embedding function means that the external sound signal is input from optical fiber, coaxial, left and right channels, and the sound signal is output from the HD Multimedia Interface output port). Through the machine or the remote control on the control knob, you can realize the sound signal extraction and embedding function, so as to realize the multi purpose machine. 2、Extraction and Embedding: In the sound extraction state, it supports 3 kinds of EDID settings: 2.0CH, 5.1CH and PASS. In the sound embedding state, through the switching button, it can realize digital sound optical signal, coaxial signal and analog sound stereo signal embedding. In addition, the sound interface input and output share the same design, which reduces the number of sound terminals and makes the product become more concise and easy to use. 3、4K HD: Supports 4K HD Multimedia Interface input and output, and supports ARC sound return function. Let your HD Multimedia Interface and sound devices connect with each other as you wish, making your sound and video equipment more convenient and comfortable to use. 4、Supported Formats: In the sound embedded state, the digital sound (optical and coaxial) input can support up to 96KHz sound sampling rate (LPCM format), and also supports for DOBLY AC3 and DTS sound format input. Analog sound (left and right channel), maximum support for 2V P‑P analog signal input. 5、ARC Function: Support ARC sound return function, ARC sound return, the sound can be from the digital sound channel (optical, coaxial), and analog sound channel (left and right channel) output at the same time (analog channel output can only support LPCM2.0 format sound return). Item Type: HD Multimedia Interface Embedded Extractor Material: Metal Resolution Format: 24/50/60fs, 1080P, 1080i, 720p, 576p, 576i, 480P, 480i, 24/30/2160P Video Color Format: 24/30/36bit, 1080P, 1080i, 720p, 576p, 576i, 480P, 480i, 24bit, 2160P HD Multimedia Interface Supported Sound Formats: DTS HD, for Dolby TrueHD, LPCM7.1, DTS, for Dolby AC3 DSD Digital Sound Output Format: PCM2.0, for Dolby AC3, DTS Sound Output Sampling Frequency: 32KHz, 44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz, 192KHz Maximum Digital Sound Transmission Bandwidth (output): 25MHz Analog Sound Input and Output Levels: 2V p‑p Analog Sound Frequency Range: 70Hz to 16KHz Maximum Transmission Bandwidth: 300MHz Input Output DDC Signal: 5V p‑p (TTL) Power Adapter Specification: AC 100‑240V DC 5V 1A Remote Control Battery: CR2025 Button Battery (Shipped Without Battery) 1 x Sound Extraction Separator 1 x Remote Control 1 x Power Adapter Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
