1. 1X -compatible input and 1X -compatible output,can sync separation -compatible audio signal. Supports 1x SPDIF optical digital audio output, multi-channel RCA analog audio output Supports 12-bit Deep Color Full HD,3D and 4K2K video2. Support CEC Support multi-channel LPCM digital audio to analog output, up to 71CH. Uses 24bit or 192KHz DAC LPCM audio format indicator3. Supports 3 modes for audio output. You can switch among multi-channel, stereo (2CH) and mute.4. High tone quality, low noise DC5V adapter5. SWITCH: Audio output mode switch. Multi:Multi-channel audio Mode. Switch to this mode for the -compatible source to output 51 or 71 LPCM audio per the built-in EDID. Then RCA output 51 or 71CH analog audio, Optical output 2 channel LPCM digital audio and -compatible output bypass. Note: Need support from source player and disc for multi-channel audio output.2CH:2 channel stereo mode. Switch to 2CH mode for the -compatible source to output LPCM 2 channels audio per the built-in EDID. Then RCA, Optical and -compatible output stereo audio. Mute:Mute Mode. Then RCA, Optical no output, -compatible output bypassSPECIFICATIONS: (HDCN0033M1)-compatible resolution: up to 4K or 30Hz, 1080P or 1080I or 720P or 576P or 480P or 60HzSupport video color format: 24bit or deep color 30bit,36bitInput or Output TMDS signal: 05-15Volts p-p(TTL)Input or Output DDC signal: 5Volts p-p (TTL)DAC sample frequency range: 32-192 KHzDAC Bit rate range:16-24 BitRCA analog output level: 2V SNR (1KHz 0dB) greater or equal to 90dBTHDandN (1KHz 0dB) less than or equal to 001 percent Frequency response: 20Hz-20KHz-compatible: input cable distance: less than or equal to 15m AWG26 -compatible standard cable-compatible: output cable distance: less than or equal to 15m(1080P) or 8m(4K) AWG26 -compatible standard cableMax working current: 500mA adapter format Input:AC 100V-240V 50HZ or 60Hz, DC5V or 1AOperating Temperature range: -10 to and55Storage Temperature range: -20 to and60Operating Humidity range: 10 to 90 percent RH (No Condensation)Storage Humidity range: 5 to 95 percent RH (No Condensation)Plug Type:EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on.colour: blackMaterial: ABSSize: 205x74x26mmPackage Contents:1 x audio converterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
