Sound:



1. Plug in the HDMI cable to your laptop, and ensure it is firmly in the HDMI port on the side of the cabinet. 


2. Turn on the 2 Black boxes which have the power rocker switches in the centre, which will have blue power lights when turned on.  


3. The 'behringer' Box at the top of the stack has the sliders labelled. Ensure that the ones labelled HDMI and Main Mix pushed up to about 3/4 of the way. (next to where the 0 is).


4. Make sure that the PC speaker is set to '1080P 3D 2CH' . 


The Audio should now be coming through the speakers hanging from the ceiling. Ensure that the volume is turned up on your PC to max before changing any of the sliders to increase the volume that way.



Projector: 


1. Make sure the HDMI is secured in both the Laptop and the port on the side of the A/V Stack.


2. Once the projector has warmed up, it will start to show the screen. If the screen is just showing blue, press the HDMI button on the remote which will change it to display the correct input.
