ProjectorsPromethean Projector has no sound

Hi Kim,
The ActivBoard’s amplifier doesn’t have a port for an optical audio cable. You may need to look at a third party adapter or alternative cables in order for this to work.
You can refer to article 10408 on for the outputs on the amplifier. You will need to ensure that a 3.5mm Audio cable is used.
