To find the control driver for the Neo6A or Neo8A please login to Cloud Monitoring and download the driver for your 6A or 8A (please be aware this driver is titled Neo8 and this is the driver you need to use). If you do not have access to Cloud Monitoring please contact Pulse-Eight directly or your Distributor where you purchased your unit from.
The Neo6A & 8A have audio breakouts and as such do not support routing of the audio break out. They are fixed as source audio extraction. There is no matrixing for the Audio breakouts, they are matched to the HDMI inputs. So for example the video input for HDMI 3 will mirror to audio output 3. This is not switchable or controllable. Only the NeoX+ offers audio that can be matrixed.
If you wish to use the Audio breakouts with a control system (such as Control4) you will need to map the audio to the source and map the video to the outputs. You can map the audio to source by downloading the relevant Driver for the source device (i.e the Apple TV driver) or creating your own custom driver for the source.
For further information on installing your Neo6A or 8A you can find the Installation Guides here.
