2.0 FUNCTIONS

2.3 PRESET HANDLING BLOCK 

In applications using multiple Model 1788’s, such as theater and live concerts, it is critical that mic
preamp settings can be stored and changed quickly as Presets. The Model 1788-R is a state-of the-art
solution that not only duplicates the key functions of the Model 1788 but provides a means to quickly
recall a series of settings that are used in every performance.

From the 

Preset Handling Block

presets are created (SNAP SHOT), loaded (recalled), edited and erased.

The readout displays two different digital numbers representing individual presets. The CURRENT read-
out indicates the loaded preset number (preset in use), while the NEXT readout indicates the next preset
to be loaded (which becomes the next preset in use). After power up the CURRENT readout will contain
two dashes until the comm test has been run and a preset loaded.  

Note:

While in the Preset Edit Mode the CURRENT display indicates which preset is

currently being modified. It DOES NOT indicate which preset is currently loaded to the
connected Model 1788’s.

If any presets are created on the Model 1788-R, the LOAD button will illuminate just after the comm
test, indicating the ‘Next’ selected preset is ready to be loaded into the connected Model 1788(s). Loading
a preset initiates a download of all current settings. The preset change is done when the Comm LED is
no longer illuminated.

To select the next preset, turn the SELECT knob to the desired preset which is displayed in the NEXT
readout. Pressing the LOAD button, loads the preset into the controller and shifts the preset number
from the NEXT readout to the CURRENT readout. 

When selected a new preset with the SELECT knob, the three LEDs next to the readout indicate the
preset’s status as follows:

MISMATCH - when the number of units in the selected presets do not match the number of units
detected in the comm test. A preset can still be loaded even when mismatch occurs. 

PRESETS EMPTY - no preset found.

PROTECTED – the preset is locked and cannot be overwritten or erased.

The PROTECT/UNPROTECT button can be used as a second level of protection to prevent accidental
overwritting of any or all created presets. Use the PROTECT/UNPROTECT button to toggle the protection
status of any preset. If you want to make a SNAP SHOT of a protected preset, the preset has to be
unprotected. All new presets (created with SNAP SHOT) are automatically protected.

To ERASE a preset, select the desired preset with the SELECT knob (appears in NEXT display) and
press the ERASE button. For instance, in order to prevent any confusion an invalid preset can just be
erased, removing it from the list of available presets. Preset number 1 can not be erased, as it is the
default preset in the preset edit mode.

The SNAP SHOT button is used to create a new preset or edit an existing preset. When creating a new
preset:

1. Make necessary settings on all Model 1788s

2. Use the SELECT knob to dial up a new preset number. Selection appears in NEXT display. 

3. Press SNAP SHOT to create the preset, automatically shifting the preset to the CURRENT read-
out, indicating that is the preset in use.

When editing an existing preset:

1. Select the desired preset number with the SELECT knob. Selection appears in NEXT display. 

2. Load the preset by pressing the LOAD button. The preset shifts to the CURRENT display.

3. Make setting changes on all units. If the preset is protected it must be unprotected at this time.
An existing preset can not be updated if it is protected. 

4. Press SNAP SHOT to overwrite the preset with the new settings.
