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 DecoderMaterial: Plastic and metalGross Weight: 631g/21.6ozHD Multimedia Interface Input and Output Resolution: up to 4K/30Hz 1080P, 1080I, 720P, 576P, 480P, 60HzHD Multimedia Interface Input Supports Video Color Format: 24bit/Deep 30bit/36bitHD Multimedia Interface Input Supports Audio Formats: DTS HD, TrueHD, LPCM, DTS, for Dolby AC3, DSDDigital Audio Conversion Format Supported: LPCM, up to 7.1HD Multimedia Interface Input Maximum Transmission Bandwidth: 300MHzHD Multimedia Interface Input Maximum Transmission Rate: 9GbpsInput and Output TMDS Signal: 0.5 to 1.5Vp-p TTLInput and Output DDC Signal: 5Vp-p TTLDAC Sampling Frequency: 32 to 192 KHzDAC Bit Rate: 16 to 24 BitRCA Analog Output: 2V RMSSignal To Noise Ratio: 1kHz at 0dB ≥90dBTotal Wave Distortion: 1kHz at 0dB ≤0.01percentFrequency Response: 20Hz to 20KHzHD Multimedia Interface Input Cable Length: ≤15mAWG26 HD Multimedia Interface Input standard cableHD Multimedia Interface Output Cable Length: ≤15m ,1080P /8m 4K AWG26 HD Multimedia Interface Input standard cableMaximum Operating Current: 500mAPower Adapter Specifications: US AC 100V-240V 50/60Hz, DC 5V/1AWorking Temperature: -10 to +55℃Storage Temperature: -20 to +60℃Working Humidity: 10 to 90 percents RH, non condensingStorage Humidity: 5 to 95 percents RH, non condensingProduct Size: 205x74x26mm/8.1x2.9x1.0in.Package List:1 xSound Decoder1 x Power Adapter1 x ManualNote:Please use and maintain proper maintenance to ensure product performance and normal work.1.
