I have the PRM-35 projector and can not get any sound when I mirror my ipad with the apple tv. I notice there are no speakers with this projector. Can I hook cable from projector to my board to use its sound?

The PRM-35 Projector
does not have any audio output ability; any audio connection would need to be
made between the iPad/AppleTV and the board’s amplifier or other audio system

Thank you! Trying to figure out that next step, since there is no audio port on apple tv, wonder if I can connect headphone port to board’s audio??

just looked at apple tv a bit closer (had to get on a ladder) and there is an optical audio port that I need to get an optical audio cable and which port on the board would I plug it into??

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 http://www.PrometheanKB.com for the outputs on the amplifier. You will need to ensure that a 3.5mm Audio cable is used.

I am having the same issue with my apple tv. When it is mirroring on the board I have no sound. I also have the PRM-35 projector. I need to know what type of cable I need and where I need to connect. Do I go from the apple tv to the board? The apple tv only has the optical audio output. I have tried plugging external speakers into the ipad and using a bluetooth speaker and when those are connected I cannot mirror. Thank you.

If you are using a 3.5mm audio cable for the amplifier, where do you put the other end? The apple tv does not have a port for that.

I was able to use an adapter that was an HDMI to VGA+ audio adapter from Tripp Lite and this allowed the mirroring from the ipad to also hear the sound, I did have to unplug the cable from the computer to the board when we wanted to mirror. I actually had help with this from our main tech company who helps us out a few times a year.

Thanks for posting on the Support Community.
The PRM-35 projector doesn’t carry any audio output from the HDMI source, as such you need need to use some form of third party equipment/adapter to allow the sound to come through the ActivBoard using the available 3.5mm audio sockets on the ActivBoard amplifier and the Apple TV.
