You need to check the frame delay specs on your Kramer switcher, If for instance it allows you to switch seamlesly un synced sources, it will have at least one frame delay sometimes two frames. Projectors especially dlp will usually also introduce a frame delay, each frame is 1/29.97 of a second. to keep things in sync you need to get an audio delay which will allow you to add the frame delays.

Where this can get to be an issue is if in stead of video you are using a feed froma camera thru a switcher do a dlp projector in a live situations, here you are sort of stuck, you cannot delay the audio unless ALL of it is pre recorded.

Fun fun fun, a lot people cannot detect a single frame delay, more can detect a two frame delay and most can detect 3 or more frames
