Audio Connections - Datavideo SE-900 Instruction Manual

Audio Connections

The SE-900 does not have any audio mixing capabilities but it does feature an Audio Delay Circuit. It is also
able to de-embed audio streams from DV and SDI inputs, and supply balanced audio from each of the input
channels.
The SDI Input settings can be set to select the audio channels that you want to de-embed - see Set Up
Menus - Video In for details.
A DV or SDI Video Input card has two miniature 3 pin XLR audio connections, which provide balanced audio
for you to feed to an external audio mixer.
The Audio Delay Circuit allows you to add a delay to the audio stream in order to maintain lip-sync on your
recordings. For setting up the delay please see Set Up Menus - Audio Delay and Audio Delay Circuit
Depending on the type of video inputs and outputs the SE-900 will delay the video stream by up to 4 frames,
so the audio needs to be delayed by the same amount.
The following table is a guide to the video delay times within the SE-900. These times are based on internal
synchronisation; with external Genlock the delays would be reduced.
