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 video 2. Support ; Support multi-channel LPCM digital audio to analog output, up to 7.1CH. Uses 24bit /192KHz DAC; LPCM audio indicator 3. Supports 3 modes for audio output. You can switch among multi-channel, stereo (2CH) and mute. 4. quality, low noise; DC5V power adapter 5. SWITCH: Audio output mode switch. Multi:Multi-channel audio Mode. Switch to this mode for the -compatible source to output 5.1/7.1; LPCM audio per the built-in EDID. Then RCA output 5.1/7.1CH 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 bypass SPECIFICATIONS: (HDCN0033M1) -compatible resolution: up to 4K/30Hz, 1080P/1080I/720P/576P/480P/60Hz Support video color : 24bit/deep color 30bit,36bit Input/Output TMDS signal: 05~15Volts p-p(TTL) Input/Output DDC signal: 5Volts p-p (TTL) DAC sample frequency range: 32~192 KHz DAC Bit rate range:16~24 Bit RCA analog output level: 2V (1KHz@ 0dB) greater or to 90dB +N (1KHz@ 0dB) less than or to 001% Frequency response: 20Hz~20KHz -compatible: input cable distance: less than or to 15m AWG26 -compatible standard cable -compatible: output cable distance: less than or to 15m(1080P)/8m(4K) AWG26 -compatible standard cable Max working current: 500mA Power adapter Input:AC 100V~240V 50HZ/60Hz, DC5V/1A Operating Temperature range: -10 to +55 Storage Temperature range: -20 to +60 Operating Humidity range: 10 to 90%RH (No Condensation) Storage Humidity range: 5 to 95%RH (No Condensation) Plug Type:EU Plug,it applies to Indonesia, , , , and so on. colour: black Material: ABS Size: 205x74x26mm Package Contents: 1 x audio converter Only the above package content, other products are not included.
