Q: Does this HDMI Matrix Switch support remote IR?
No. We recommend using RF remote controls, see the ACCESSORIES Tab.

Q: I see the the HDMI extenders come with 2-remote IR cables, will the remote IR work with this matrix?
No, the cables are used when the application has one source and one widescreen. They can't be used with this matrix and need to be set aside and not used.

Q: What is MHL?
MHL is a technology standard developed by some of the top smartphone and consumer electronics manufacturers in the world Nokia, Samsung, Silicon Image, Sony and Toshiba. Smartphones and tablets with MHL can connect instantly to larger high-definition TVs to display streaming video, pictures and games all with surround sound. MHL means your content is larger than life so you can sit back, enjoy and experience.

MHL has other bonuses -- it charges your phone while its connected to the TV. And you can use the TV's remote to control the content coming from your phone on the big screen. MHL shares the same connector on your phone that you use to charge your phone. If you have an MHL TV, MHL shares the same connector as an HDMI port. Simply connect your MHL-enabled phone or tablet to your TV, monitor or projector to mirror everything on your phone to the larger screen display. TV not MHL-enabled? An MHL adapter makes any HDMI display an MHL display.

Q: What is the audio switch for?
The button for the Audio output mode can choosen for 5.1CH ,2.0CH ADV [Advance Audio]. Three kinds of audio output modes can be circulated switching. When you switch to the 5.1CH audio mode output the Digital audio signal receiving terminal must support DTS/DOLBY-AC3 decode, or the input D audio signal receiving terminal will have no sound output. If you need stereo than switch to the 2CH audio mode.

When audio output switch to the ADV [Advance Audio] mode, the audio output format will be decided by the audio signal receiving machine audio decode ability. The splitter will output 7.1 channel audio signal while the output end connects the av amplifier with HDMI port that support 7.1 channel audio decode.(the HD Source signal itself is 7.1 channel)

Q: What is ARC?
The (ARC) Audio Return Channel in HDMI 1.4 enables a TV, via a single HDMI cable, to send audio data ½upstream ½ to an A/V receiver or surround audio controller, increasing user flexibility and eliminating the need for any separate S/PDIF audio connection.

TVs have always been able to receive multi-channel audio through an HDMI connection, and this is still a typical use-case, with the TV positioned downstream from content sources and any connected audio equipment. However, if a user had a TV with a built-in tuner or DVD player, and wanted to send content upstreamfrom the TV back to the audio system, a separate connection had to be installed, typically an S/PDIF cable.
