1.Press RECALL.

2.Select the memory register you wish to recall from as follows:

If you are using Bank Mode, select a pattern button to designate the memory register in the selected bank. You may also use the Bank knob to change the selected bank before recalling.

If you are using Direct Access Mode, select a pattern button to designate the desired bank and then select a second pattern button to designate the memory register.

Note:

Recalling a memory register that requires a new image to be loaded from a USB drive into a Media-Store channel may result in the currently loaded image being displayed for a few frames while the new image is loaded.

You can exit without recalling a memory register by pressing any button other than a Wipe Pattern, dedicated key transition, CUT, AUTO TRANS, or source button.

Bus Hold

You can choose to have a bus remain unaffected by a memory recall (the selected source on the bus is not replaced with the source stored in the memory).

To perform a Bus Hold:

2.Press RECALL.

3.Select the memory register you wish to recall from as follows:

If you are using Bank Mode, select a pattern button to designate the memory register in the selected bank. You may also use the Bank knob to change the selected bank before storing.

If you are using Direct Access Mode, select a pattern button to designate the desired bank and then select a second pattern to designate the memory register.

The source on the bus you selected will not change when the memory is recalled (the source setting stored in the memory for that bus is ignored).

Memory AI and Recall to Preview

The switcher can be set so that recalling a memory does not affect what is currently on-air. There are two modes you can choose from:

Recall to Preview — The switcher only recalls those elements from the memory register that are not currently on-air. Background elements are recalled to the Preset bus.

Memory AI — The switcher uses the contents of the memory register to configure the Next Transition area and the Preview bus. The switcher is configured such that the next transition will make the on-air state the same as the state saved in the memory register.

Memory AI and Keys

Enabling Memory AI mode changes the way key elements are recalled. If a key is currently on-air, the element for that key is recalled in the next available off-air key. If there is no available off-air keys, the element is not recalled.

All resource sharing is set to FLOAT mode so that key elements may be recalled to other keys than originally stored.

For More Information on...

Resource sharing, refer to the section “Resource Sharing” on page 14.
