Simultaneously separates HD multimedia interface audio signals, supports 1 channel SPIDF optical digital sound output, and supports multi channel RCA analog sound output. 224bit/192KHz: HD multimedia interface supports 12 bit deep FULL HD, 3D and 4Kx2K video. This converter adopts 24bit/192KHz DAC audio conversion chip. 3Multi 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. 4Low 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. 5Widely 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.
