CABLING AND WIRING
To simplify console connection, draw up a
facility wiring plan listing the console's audio
and logic connections with peripheral devices.
Identify and create tags for each cable and then
list each connection in a master facility wiring
logbook. This facilitates initial wiring installa-
tion and future system wiring changes, equip-
ment updates or system troubleshooting.
Analog audio connections require two-
conductor stranded, insulated, foil-shield cable
containing a separate shield drain wire
(equivalent to Belden 8451, 9451 or 8761).
AES/EBU connections require 110 ohm two-
conductor stranded, insulated, foil-shield cable
containing a separate shield drain wire
(equivalent to Belden 1806).
S/PDIF connections, which are unbalanced
use coaxial cable connected between the + and
GND connects on the inputs.
Wire Preparation
All X-mixer audio and logic wiring termi -
nates in AMP MR receptacle contacts. Strand-
ed wire of 22 to 26 AWG, with insulation
diameters of .040 to .060 inch, can be used
with the AMP MR receptacle contacts.
Follow these steps for wire preparation:
1
Strip the cable insulation jacket back
1 1/2" [38.10 mm].
2
Remove the foil shield from audio
cables.
3
Sleeve the audio drain wire with
Teflon sleeving, leaving 9/64" [3.572 mm] of
the drain wire exposed.
4
Use 3/4" [19.05 mm] of heat-shrink
tubing to sleeve the end of the jacket, centered
on the cut. Shrink the tubing to hold any drain
wire sleeving in place.
5
Strip the insulation back from all
signal wires 9/64" [3.572 mm].
Audio Cable Shield Note: To follow recom -
mended grounding procedures, sleeve all drain
wires with Teflon sleeving and put heat shrink
tubing over all cable jacket cuts to insulate the
shield wire.
Crimp Tool Operation
A hand crimper is included in the tool kit.
The tool crimps the insulation and wire barrels
on the AMP receptacle contacts in two crimp
actions.
Follow these instructions for using the
crimp tool:
Crimping a wire with this hand
tool is a two part process. The crimp tool has an

A and B anvil. The smaller B anvil is used to
crimp the wire. The larger A anvil is used to
crimp the insulation. Hold the crimp tool
with the printed side up. Insert the contact
from the opposite side, with the barrel open-
ings up. Insert the wire from the printed side
until the uninsulated part of the wire reaches
t h e b a r r e l o f t h e c o n t a c t . C r i m p t h e
uninsulated wire first in the B anvil and then
the insulation next in the A anvil. Close the
tool only until the anvil holds the contact
firmly in place. Do not crush the receptacle.
A properly crimped receptacle contact is
inserted and locked into the appropriate con-
nector housing following the pin-out dia -
grams. A light "click" will be felt as the con-
tact's locking tab engages the locking tab slot.
For wiring changes, use a Contact Removal
Tool to depress the locking tab while pulling
the contact and wire out of the connector.
