DiGiCo Waves MultiRack SoundGrid - Manual (Page 30)

DiGiCo Waves Operation
1-30
Use the Group Properties window to create groups of Racks and align their latencies. Open this window from the pull-down menu
located at the top of a Rack or from the Window menu.
In the Group Properties window, you can create up to 16 processing groups, each of which can contain any number of Racks.
Create a group by double clicking on a Group Name cell and typing the name you want to assign the group (using the external keyboard).
Now, decide how you want to align the processors within the group.
None
A group is created, but there is no latency alignment.
Auto
The group is delayed to match the latency of the Rack in the group with the greatest total latency.
Manual
Manually delay the group by a specific value by entering it in the Latency field. The value is displayed in samples, milliseconds, meters or
feet, depending on your choice in the pull-down window. The minimal value allowed for this setting matches the latency of the Rack in the
group with the greatest total latency.
Groups are color-coded to make for easier identification. Color selection is based on placement in the list, and is not user-definable. At the
bottom of the Group Properties page is the Align All section.
Here you can align all of the groups of Racks in order to create a unified timing for all channels. The Auto setting will offset all of the
groups to match the timing of the group with the greatest latency, while Manual will delay all groups by a specific value.
Below the Align All section is the “Speed of Sound” setting. This parameter control, expressed in meters per second, allows you to
calibrate MultiRack SoundGrid’s latency controls to match measured speed of sound. The speed of sound at sea level, at a temperature of
20 degrees Celsius and dry air, is 343 meters per second.
