Using Presets

The current configuration (configuration 0) can be saved as a preset in any one of 16 preset memory addresses. Each switcher has as many presets available from the front panel as it has input and output buttons. For example, the MVX 44 has 8 presets (4 input buttons and 4 output buttons) available from the front panel and the MVX 88 has 16 (8 input buttons and 8 output buttons). Figure 11 on the next page identifies preset numbers available from the front panel for each matrix size; preset numbers above those listed are available under RS-232 or IR control only (see the “Remote Operation” section).

NOTES: • 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 they are recalled as

the current configuration. Presets can be viewed using the Extron Matrix

Switchers Control Program (see the “Remote Operation” section).

• 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.

• All models have 16 presets; on models with fewer than 16 input and output buttons, preset numbers that are too high to be available from the front panel are still accessible under serial port or Ethernet control.
