1. R/C OVERVIEW
Indirect MIDI Control
MIDI controllers can access 1788A’s through the LAN indirectly by interfacing with one or
more 1788A-R’s. A most basic example is illustrated below.
Ethernet LAN
Many applications call for more sophisticated remote control or control at greater distances
than a MIDI port can handle. The Ethernet port is used to pipe UDP data between 1788A’s
and dedicated hardware and computer-based control surfaces over a Local Area Network
(LAN). Up to 128 1788A’s and 8 R/C units can be accommodated on a single LAN.
REFER to “Setting Up The LAN” for instructions on proper network hardware
configuration.
1.3 CONCEPT OF BANKS & CONSTELLATIONS
When under LAN connected control, 1788A’s are addressed by their NET NUMBER which
is manually assigned through each preamp’s front panel. This NET number identifies it
as an individual unit and as a member of a BANK. Banks are contiguous Net numbers in
groups of 16 according to the following table:
