Using presets

The current configuration (configuration 0) can be saved as a preset in any one of

16 preset memory addresses. Each switch has as many presets available from the front panel as it has input and output buttons. For example, MAV 44 has 8 presets (4 input buttons and 4 output buttons) available from the front panel and the MAV 88 has 16 (8 input buttons and 8 output buttons). Preset numbers above those available from the front panel are available under RS-232 or IR control only. See chapter 4, Remote Operation.

• 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 4, “Remote Operation”, 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.
