is needed is for the wires destined for the connector be snub cut and laid
out in order (although tubing should be used on bare drain wires). An
empty DB-25 or DB-9 connector is inserted into the tool, indexed to the
first pin, and the wires are inserted one by one into the jaw and the
trigger squeezed. In this way a single multipin connector can be
completely wired up in a minute or two.
In the event of a wiring error, connector pins may easily be removed
from the shell with the wire still attached, and inserted into the correct
position. Observe the side of the connector, with the metal part down.
You will see a row of "Vees"—simply press the top of the vee together
with a scribe or other sharp instrument; this will unlock the pin from the
shell, and it can be removed and inserted into the correct position.
Spread the vee apart to lock the pin in the new position. It should never
be necessary to discard a connector due to a wiring error.
Note that mating right angle hoods for each connector are also
supplied with the console. These have locking tabs that hold the
connectors securely to the bottom of the console mainframe.
Connection Procedures
As supplied from the factory, the console requires no logic connec-
tions to function. Therefore an orderly installation begins with the
audio wiring. Note this manual is organized by module type (inputs,
submasters, masters, monitor modules, etc.); each chapter contains
detailed wiring instructions for its module type. Proceed through the
manual, chapter by chapter, until all modules have been wired to suit
your particular installation requirements. Once proper audio operation
is verified, go back to each individual chapter and proceed with control
wiring.
Insert Points
Certain module signals have built-in insert patch points in their
signal chains to allow outboard audio processing. These include
SUBMASTERS (with both submaster and auxiliary master insert
points) and STEREO MASTERS (stereo master and mono master
output signals).
Normally these points are internally bridged at the factory (via
PCB-mounted jumpers) prior to shipment. If you intend to use out-
board signal loops at these points, you must remove the factory
installed jumpers. See pages 3-4 and 3-5 (submasters) and 4-5 (stereo
masters) for details.
NOTE: While input modules also have insert points, these may simply be
front panel bypassed by the “insert” switch at the top of each module.
NOTE it is also possible
to bridge the insert points
at each module’s DB-25
I/O connector by connect-
ing “INSERT OUT HI”
pins to “INSERT IN HI”
pins. See individual mod-
ule pinout drawings
(listed below by page
number) for details.
