No TV Hookup Required
The operation of this HDMI audio processor does not require HDMI hookup with a TV.
Theanalog audio output or optical audio output from the device remains coming through when the HDMI output of this device is not connected with a TV.
EasyEDID Switch For Audio Output Mode
Thisunit is featured with EDID switch on the front panel for manually selectingbetween various audio output modes:
- TV Mode: Switch to TV mode for the HDMI source to output audio according to what the TV or AV receiver can support.
- Bitstream Mode: HDMI source will output bit-stream audio such as AC3, Dolby 5.1, DTS 5.1, which will be extracted and routed through its optical audio output.
- LPCM 7.1CH Mode: all 3.5mm audio ports output LPCM 7.1CH sound. Optical port output 2 channel PCM digital audio.
[Note]: Depending on the input audio format, the unit may not output audio through all output port. For Example, the optical output port will have no audio when the input audio format is more than LPCM 7.1CH.
HDMI LPCM 5.1 7.1 Audio Decoder
This HDMI audio decoder is a great device for decoding the LPCM 5.1 and 7.1 surround sound outputfrom devices such as PS4, Wii U, Blue-ray player, etc into 7.1 and 5.1discrete channel sound through its front left/right, center/subwoofer, rear left/right and rearcenter left/right ports to deliver a directional and more realistic effect.Source player and DVDdisc must have the capability of providing multi-channel audio output for thisprocess.
The decoded analog audio output from this device produces an accurate duplicate of sound whichis bit-for-bit identical to the studio master, so listening at home is the ultimate home cinema experience.[Note]: Dolby TrueHD or DTS-HD Master Audio can only passed through the HDMI output with no decoding and no conversion.
Discrete Channel Sound
This HDMI audio processor decodes LPCM 5.1 or 7.1 audio and outputs through 4 of its 3.5mm audio terminals usingoptional splitters/cables (not included)
- FL/FR OUT: front left and front right audio outputs
- LFE/FC OUT: subwoofer and center audio outputs
- RL/RR OUT: rear left and rear right audio outputs
- RLC/RRC OUT: rear left center and rear right center audio outputs
HDMI To Optical Audio Output
This HDMI audio converter can extract the compressed Dolby Digital, AC3and DTS 5.1 and route through its optical audio out.
Source player and DVDdisc must have the capability of providing multi-channel audio output for thisprocess. [Note]: The optical output port will have no audio when the input audio format isLPCM 7.1 or 5.1CH.
