Input Level
Generally, when setting up your audio mix, the first step is to normalize all your inputs. This
means adjusting the input level knob on each input so you can optimize all the levels to their
highest strength without clipping.
This control is at the top of each track under the tally light. Change the level by clicking on the
knob and dragging left to decrease the level, or right to increase. By setting the input control,
itbrings all the inputs up to a common signal strength so they are all at their strongest without
clipping. Then you can start making advanced changes and refinements.
Delay Control
Sometimes when using analog audio via your switcher’s XLR inputs, there may be a slight
difference in the sync between analog audio and video. For example, the analog audio may
sound slightly ahead of the video. This is because analog audio is independent of the video
inputs and could be coming direct from a microphone, while the SDI inputs might have some
delay depending on upstream equipment, such as some cameras and video processors.
Setting the audio delay will ensure the analog audio input is perfectly AV synced to the video
inputs from cameras.
To adjust the amount of delay on the selected input:
1 Click on the delay indicator beneath the input audio level control knob on the
channel strip.
Click on the delay indicator below the level
input knob to open the delay control
A small popup window will open containing the delay adjustment knob.
2 Click on the delay knob and drag left to decrease the amount of delay, or drag right to
increase. The amount of delay is measured in frames. Close the window by clicking on
the small ‘x’ in the top corner, or move the window to a safe place on your desktop if
you need to make further adjustments later.
