Putting Sound in the Picture
8 or 12 way EDAC connector 2U pan-
els are available to interface analog
I/O in one of the styles shown in the
table.
The choice of style depends on the
installation with the major influence
normally being the number of circuits in
the installation cabling. Style 2 lends itself
to easy installation with 12 pair cable,
though the vast majority of users opt for
style 1 as this works well with commonly
available 8 circuit cables.
The different styles are achieved using
interface cards which attach to the rear
of the 2U panels to provide different
combinations of MDR (SCSI-style)
connectors per EDAC.
In many cases, customer cabling with
EDAC connectors for the console on one
end may have the opposite end broken
out to IDC (punch-block) connectors. This
can make for easy routing of circuits to
the required destinations.
The panel mounted connectors are
38 pin, males - EDAC 38MP. Cables
connecting to these panels need 38 pin,
female cable connectors (38FC). Refer
to the photograph to be sure your EDAC
supplier interprets male and female in
the right way. As with all the installation
connectors, unless specially ordered as
optional extras, mating EDAC connectors
for customer cabling are not supplied by
Calrec.
EDAC connectors can be ‘keyed’ with the
two locating pins, one of which is larger
than the other. Each pin can also be fitted
with the slot at one of six different angles
which can make for a vast range of unique
pairings of connector halves. This can be
a major inconvenience during installation
testing and for maintenance. For this
reason Calrec assembles all EDACs in
the same way with the large pin at the top
which is the same end of the connector
as pin A. The keying pins are all aligned

EDAC and other styles of connector panel
link to the console I/O back plane via
Calrec supplied cables, normally of 1, 3 or
5 metres but this length can affect pricing.
Most of these cables have balanced audio
pairs with an overall screen and moulded
MDR connectors.
Mic/line inputs use a hand wired cable
assembly of twin and screen cables. The
extra screen connections is the reason for
fewer audio circuits with style 1.
