Global Audio Delay
The Global Audio Delay field specifies an audio delay in addition to the CP750 decoding

×
AES PCM. Use this function to synchronize the audio
with the video from digital cinema projectors, which add a video processing delay. Use the
up and down arrows to set the Global Audio Delay between 0 and 250 ms. This delay
value is set independently for each digital input.
Mute Main Bsl/Bsr Output Pins
Choose Enable to mute these pins if your auditorium does not use them.
Note: Systems that use an external video scaler may add another decoding delay.
