Management Extents

Storing and recalling presets can be done only by remote control. Recalling presets can be done by indirect MIDI as well as by the 1788A-R and the PC software R/C. The extent of preset management depends on the form of R/C according to the table below.

Constellation and Bank Capture/Recall

Since one 1788A-R controller can address only one bank, it can only capture the state of its own bank. This is typically no limitation since it is rare to see more than 16 1788A’s (which can fit in one bank) in a whole system. That’s 128 mic channels which covers all but the most elaborate sound installations. One 1788A-R will provide total preset/recall capability for a one-bank constellation of up to 128 mic channels.

NOTE: Sometimes, for operational convenience, a smaller number of preamps are assigned by NET numbers to two or more unfilled banks. Therefore, more than one 1788A-R will be installed and assigned to the multiple banks. Banks do not have to be

filled to create a viable constellation.

Hardware Recall

An operator could manually use controls on each 1788A-R to individually recall numbered presets one by one. When only one 1788A-R is in control of the whole constellation, this is a simple operation. However, it may be less convenient if more than one 1788A-R is in use, requiring the operator to manually recall from each R/C unit.

Hardware Capture plus MIDI Recall

In a show control scenario, a MIDI controller can be used to recall presets that are to be enacted regularly. In that case, it would be connected to the 1788A-R MIDI ports and be programmed to send a sequence of Preset commands to tell each 1788A-R in turn to recall a specified preset number. An existing mixing or lighting console or small stand- alone MIDI controller unit can suit the purpose of automating recalls.

Software Presets

The software R/C running on a PC or Mac integrates all the bank functions universally and can not only capture a whole constellation snapshot, but also command a constellation preset change with mouse-click ease. Project management is provided with a file system for saving and recalling constellation presets, assigning preamp unit and channel labels, preset labels, and other essential information.
