WIRE PREPARATION
All Legacy audio and logic wiring terminates
in AMP MOD IV receptacle contacts at the con-
sole. Stranded wire of 22 to 26 AWG, with insula-
tion diameters of .040 to .060 inch, can be used
with the AMP MOD IV receptacle contacts.
Follow these steps for audio wire preparation:
1 Strip the cable insulation jacket and foil shield
back 1½" [38.10 mm].
2 Remove the foil shield and sleeve the drain
wire with 20 AWG Teflon sleeving. Leave
9/64" [3.57 mm] of the drain wire exposed.
3 Cover the cut end of the jacket with 3/4"
[19.05 mm] of heat-shrink tubing. Shrink this
tubing, centered on the jacket cut end, to hold
the drain wire sleeving in place.
4
Strip the signal wire insulation back 9/64"
[3.57 mm].
5 Crimp the receptacle contact onto the wire
and insulation.
Audio Cable Shield Note:
To ensure your in-
stallation follows recommended grounding pro-
cedures, you must sleeve all drain wires with Te-
flon sleeving and put heat shrink tubing over all
cable jacket cut ends to insulate the shield wire.
Cabling and Wiring
Before installing the console, draw up a facility
wiring plan that lists the console interconnections
with all peripheral devices. Identify and create tags
for all audio and logic cabling. List each connec-
tion in a master facility wiring logbook to facili-
tate wiring installation, future system wiring
changes, equipment updates, and system trouble-
shooting.
Refer to the module Quick Connection Guides,
on pages 2-16 to 2-49, for information on each
audio and logic connection (including block dia-
grams for each logic interface connector) and on
each module’s setup DIP switches.
REQUIRED CABLES AND WIRE
The Legacy uses the following types of cables
and wires:
• Analog audio connections require two-
conductor, stranded, insulated, foil-shield
cable using 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 1800A).
• Logic control cables require stranded, 22
AWG, multiple-conductor, non-shielded,
jacketed cable (equivalent to Belden 9423,
8457 or 9421). The number of conductors
used is determined by the application. Typi-
cally cables with five and eight wires are
most often used for constructing logic
cables. Even though there are eighteen dis-
tinct signals on the Logic Interface connec-
tor, only a handful are typically used for
any given application.
