Module Overview
Every RD-12 has these two modules; together they per-
form all central signal and control processing for the console.
The CPU-5 is the console’s central controller module; the
DSP-5 is the console’s digital signal processor. With one
exception, AES SYNC (below), both modules are user-
transparent—that is, they have no external controls, all their
internal programming options are for factory use only, their
AMP I/O connector ports have no user-applicable pins, there
are no user replaceable parts inside (though complete mod-
ules may be ordered; see Appendix).
AES Clock Sync
If you wish to sync your RD-12 console to an external
clock source (or use the console master clock signal to control
an external device) the AES Sync port is available on the
DSP-5 module AMP A connector:
Pin 1 – AES Sync In SH
Pin 3 – AES Sync In HI
Pin 2 – AES Sync In LO
Pin 4 – AES Sync Out SH
Pin 6 – AES Sync Out HI
Pin 5 – AES Sync Out LO
CPU-5 Display
The alpha-numeric display on the CPU-5 module is used
at the factory for programming purposes. In the field the
default display is always “RD-5”, with the dash character
flashing. This might occasionally change to show an error
message for a second or two (for example, if you have hot-
plugged a module into the mainframe), but this should clear
quickly.
