Configuring Audio with the Neo X+

CONFIGURING AUDIO

For the NeoX+ there are two audio modes of operation: Source Mode and Sink Mode. By default, when you first install the matrix, the unit is set to Sink Mode in passive.

Sink Mode is the preferred method when setting up the Neo X+ in an installation that does not have a dedicated audio matrix switch.
 Sink Modes offers two sub-modes of operation:

• Passive mode allows for audio routing from any input to any of the audio output zones, which by default is intended to match the video routing. Passive mode does not support HDMI-ARC. 
• Active modeoffers the same capabilities as passive mode, but it will also enable the following features:
  • Audio delay and volume control of the stereo outputs
  • ARC (HDMI). When feature is enabled, the matrix will automatically manage when audio is coming directly from the TV, over the HDMI Audio Return Channel (ARC), and output over the respective audio zone output. 

Source Mode is the legacy routing where the audio outputs zones A to H are locked to HDMI inputs 1 to 8 respectively, and with audio output zones I and J linked to audio inputs 9 and 10.  This mode is generally used in larger installations where the input audio is being fed directly to one or more dedicated audio matrices. 

Note: if audio outputs are connected to stereo/phono jacks on the audio output zones, the video matrix will automatically downmix multichannel audio (including Dolby 5.1) to stereo (2 ch). Please be aware this is only for Dolby 5.1 and this does not work for DTS or other formats.

For further information on the Audio Modes and how to change between Sink Mode and Source Mode, please refer to the latest installation manual found at docs.pulse-eight.com

Note: Some changes require the reboot of the system in order for the changes to take effect.
