question

Is the input on this device ARC compatible? I want to come out of the ARC port on my tv and plug the optical audio output into my receiver, which is audio-only.

When this product receives a multi-channel signal ...

When this product receives a multi-channel signal (e.g. multi-channel PCM) from a source (e.g. Apple TV Gen 4), does it downmix the multi-channel signal (i.e. combine the channels) to produce the stereo (2 channel) analogue output, OR is the 2 channel analogue output simply the left and right embedded channels from the multi-channel extracted without downmixing?
Asked by: Kevin
Kanex does describe the process as down mixing. However they do not elaborate further on the exact method used.

question

Does it support HDMI Audio from a Dolby Digital Plus (DD+) source, outputting correctly to toslink (source such as Netflix or Google Play Movies coming in through Chromecast)? I've had trouble with my viewHD HDMI to toslink for center channel voice audio on the more recent movies that use DD+. No voice audio or center channel audio comes through the toslink.
Asked by: Bryan B.
The below links lists all of the formats supported by this unit for both HDMI input and the Toslink output. While a number of Dolby formats are supported, Dolby Digital Plus (DD+) is not on the list.http://bit.ly/1TLyRMB
