The EDGE A has an HDMI ARC (Audio Return Channel) input to allow you to create a connection to a TV that supports ARC function.
The TV ARC input is labelled as D4 on the front panel source selector.
With some TV's, the EDGE A will output a distorted sound if you are viewing HD content such as:
Amazon Instant Video Apps
Satellite TV Provider e.g. Sky, Virgin TiVo etc.
This occurs because these will output multi-channel (surround) sound as a default setting.
As the EDGE A is only able to decode a stereo PCM signal, you will need to ensure the audio output of your TV/App/Box’s settings are configured to LPCM/Stereo. If you are unsure of how to amend your settings, please consult your TV/Box’s manufacturer.
