Feature: 1. High Definition Input: The sound decoder supports 1 HD multimedia interface high definition input and 1 high definition output. Simultaneously separates HD multimedia interface audio signals, supports 1 channel SPIDF optical digital sound output, and supports multi channel RCA analog sound output. 2. 24bit/192KHz: HD multimedia interface supports 12 bit deep FULL HD, 3D and 4Kx2K video. This converter adopts 24bit/192KHz DAC audio conversion chip. 3. Multi Channel: The audio decoder support multi channel LPCM digital sound conversion into analog sound output, up to 7.1 channels. LPCM sound format LED indication. 4. Low Noise: Premium audio quality, low noise, supports three sound output modes, can switch between multi channel, Multi, stereo, 2CH and mute. It helps you to synchronously separate the digital sound from the signal to the SPDIF optical output, and at the same time convert the LPCM digital sound stream through the internal DAC and output multi channel analog sound to your power amplifier. 5. Widely Applicable: Support 2CH 5.1CH 7.1CH and other LPCM digital audio signal conversion. Can be used with high definition output terminals of many entertainment devices such as DVD players, Blu ray players, network players, set top boxes, PS2, PS3, Xbox360, PC, etc. Specification: Item Type: Sound Audio Decoder Material: Plastic and metal Gross Weight: 631g/21.6oz HD Multimedia Interface Input and Output Resolution: up to 4K/30Hz 1080P, 1080I, 720P, 576P, 480P, 60Hz HD Multimedia Interface Input Supports Video Color Format: 24bit/Deep 30bit/36bit HD Multimedia Interface Input Supports Audio Formats: DTS HD, TrueHD, LPCM, DTS, for Dolby AC3, DSD Digital Audio Conversion Format Supported: LPCM, up to 7.1 HD Multimedia Interface Input Maximum Transmission Bandwidth: 300MHz HD Multimedia Interface Input Maximum Transmission Rate: 9Gbps Input and Output TMDS Signal: 0.5 to 1.5Vp-p TTL Input and Output DDC Signal: 5Vp-p TTL DAC Sampling Frequency: 32 to 192 KHz DAC Bit Rate: 16 to 24 Bit RCA Analog Output: 2V RMS Signal To Noise Ratio: 1kHz at 0dB ≥90dB Total Wave Distortion: 1kHz at 0dB ≤0.01percent Frequency Response: 20Hz to 20KHz HD Multimedia Interface Input Cable Length: ≤15mAWG26 HD Multimedia Interface Input standard cable HD Multimedia Interface Output Cable Length: ≤15m ,1080P /8m 4K AWG26 HD Multimedia Interface Input standard cable Maximum Operating Current: 500mA Power Adapter Specifications: US AC 100V-240V 50/60Hz, DC 5V/1A Working Temperature: -10 to +55℃ Storage Temperature: -20 to +60℃ Working Humidity: 10 to 90 percents RH, non condensing Storage Humidity: 5 to 95 percents RH, non condensing Product Size: 205x74x26mm/8.1x2.9x1.0in .
