Using presets
The current configuration (configuration 0) can be saved as a preset in any one of
16 preset memory addresses, or, as many presets as the switcher has input and
output buttons.
• Only the audio and video ties are stored and recalled; audio gain settings
are not saved, and they do not change when a preset is recalled.
• Presets cannot be viewed from the front panel unless recalled as the
current configuration. Presets can be viewed using Extron’s Windows-
based control program. See Chapter 5, Matrix Software, for more details.
• The current configuration and all presets are stored in non-volatile
memory. When power is removed and restored, the current configuration
is still active and all presets are retained.
• When a preset is recalled, it replaces the current configuration, which is
lost unless it is also stored as a preset. The recalled preset overwrites all of
the current configuration ties in favor of the preset configuration ties.
Example 5: Saving a preset
The following steps show an example in which the current configuration is saved
