1.0 INTRODUCTION
1.1 THE MODEL 1788-R REMOTE CONTROLLER
To control up to sixteen Model 1788 8-Channel Microphone Preamplifiers from a remote location we
created the Model 1788-R Remote Controller. The 1788-R has been designed to closely match the layout
of the Model 1788, ensuring easy and familiar operation.
The 1788-R comes with preset handling which allows the user to create and instantly recall up to 60
presets, for "on-the-fly" changes during a session or live concert. Presets can also be loaded (recalled) on
demand by using MIDI Preset Change Commands allowing the 1788-R to be integrated in a fully auto-
mated show control system.
Communication between the 1788-R Remote Controller and the Model 1788(s) is based on a customized
MIDI SysEx protocol using a serial port connection (RS-232 or RS-422) or standard MIDI connections.
All connectors for the 1788-R are found on the separate power supply. It is possible to attach the 1788-R
and the power supply together or leave them as separate entities depending on the arrangement you
prefer.
If you are not yet familiar with all of the functionality of the Model 1788, please refer to the User’s
Manual that came with the unit since the 1788-R duplicates most of the main functions. Information
that is vital to both the Model 1788 and the 1788-R is ONLY supplied in the Model 1788 User’s Manual.
This includes material referring to the power connection, expanded explanations on the uses of the
communication ports, a wide assortment of hook-up diagrams and a pin configuration for all connectors.
This manual covers only those features, functions and interfacing configurations that are specific to the
1788-R.
1.2 THE MODEL 1788–R REMOTE CONTROLLER AT A GLANCE
This section is meant to serve as a quick reference to familiarize you with the controls found on the
1788-R Remote Controller. Further details are found in section 2.0 with regard to the
Selection &
Validation Block, Preset Handling Block
and Secondary Functions. Since the
Local Block
and
Test Tone

are duplications of the same set of controls found on the Model 1788, we have not included
detailed explanations for those two sets of controls in this manual. Refer to the Model 1788 User’s Guide
for complete information on the proper use of the functions found in these two blocks of controls. For
your convenience, we have, however, included basic descriptions of the the
Local Block
and
Test Tone
Block
as a quick reference in this section.
