Audio

The AV systems manages sound from devices such as the computers and the DVD player, this is commonly referred to as media audio plus in addition to this the system also facilitates the amplification of voices through a range of microphones, this is referred to a voice reinforcement.

Media Audio

Media audio is selected from the last button pressed of either the right or left screen source select buttons for left or right screen.

For example if you want the right screen o show a laptop image but the left to show a video from the lectern PC ensure that PC 1 on the left screen list is the last button pressed.

The volume level of media audio can be changed using the volume up and down buttons on the left hand side of the touch screen, the media volume level is shown by the VOL bar on the right of the screen.
