XTND + CEC + ARC

Pulling audio from your display using ARC to an AVR, Amp or MHUB

Many displays sold in the last 5 years come with apps to watch TV directly from the Internet (Netflix, Disney+, YouTube etc). If you want to extract that audio to nearby speakers you have two options: 1) extract the audio using a technology within the HDMI cable called Audio Return Channel (ARC) back to an amplifier that is also has ARC or 2) extract the audio from the TV using its stereo or optical connection and run additional cabling back to the amplifier.

If the TV is wall mounted, is at a distance, or you are unable to run any additional cable to the amplification equipment then your only choice is to rely on ARC to achieve this result.

Both MHUB and XTND support ARC (check model spec) BUT there are some important points you should understand before purchasing your system.

Do they support eARC?

No. eARC is not supported currently. ARC support includes 2 channel audio (stereo) and multichannel audio upto 5.1 (if supported by your display).

Our extenders do not mimic a long HDMI cable…

Your MHUB or XTND device does not act like a long HDMI cable and should not be thought of as one. Our devices can handle HDMI features like HDCP, EDID, CEC and ARC but it doesn’t ‘pass it through’ like a standard copper HDMI cable does point-to-point.

With ARC on our XTND models for example, it doesn’t pass through to the HDMI cable on the source side. Instead our extenders exact the audio to an optical or analogue output which can then be fed in to an AVR or Amp.

This is done because the XTND is not an ARC extender. It is primarily a HDMI video extender that supports the ARC featureset.

…meaning you can’t use ARC + CEC together

So for scenarios where you want to use Sonos Amp you might have a problem because you can not use the TVs remote control to control the Sonos Amp but you have an alternative options because you can use IR passback to control the Sonos Amp instead.
