The neo:X+ has two audio modes of operation: Sink Mode and Source Mode. By default, a newly installed matrix is set to Sink Mode (Passive).
Sink Mode
Sink Mode is the preferred method for installations that don't have a dedicated audio matrix switch. It has two sub-modes:
| Sub-Mode | Capabilities |
|---|---|
| Passive | Audio zones follow the video routing. Does not support HDMI-ARC. |
| Active | Everything Passive mode offers, plus audio delay and volume control on the stereo outputs, and HDMI-ARC support — when enabled, the matrix automatically manages audio coming directly from the TV over ARC and outputs it to the respective audio zone. |
Source Mode
Source Mode is the legacy routing method. Audio output zones A–H are locked to HDMI inputs 1–8 respectively, and audio output zones I and J are linked to audio inputs 9 and 10. This mode is generally used in larger installations where input audio is fed directly to one or more dedicated audio matrices.
If audio outputs are connected to stereo/phono jacks on the audio output zones, the matrix automatically downmixes multichannel audio — including Dolby 5.1 — to stereo (2ch). This only applies to Dolby 5.1; it does not work for DTS or other formats.
Changing Between Modes
For details on how to switch between Sink Mode and Source Mode, see the latest installation manual here.
Some changes require a system reboot to take effect.
