Installation Tip:When working with the Molex connector,only strip away
about 1/4”inch (about 6mm) of the insulation from each wire.Most common
electrical problems occur when the wire is stripped too long,and can short out
against neighbouring wires behind the wall.The complete assembly should not
have any more than 1/ 16 th of an inch (or 1mm) bare wire visibly exposed
from the bottom of the connector.A quick twist of the copper strands will
ensure easy installation into the connector.Tighten the fastening screw securely.
Tip: TIP: Keeping it simple… You don’t really need to know which pin does
what.That information is located at the back of this book if you’re interested,or
trying to diagnose a problem.For now simply pick a colour pattern easy for you
to remember, and simply repeat this pattern at all the connection points. For
example,if you wire all the connectors so that from left to right they are black/
green/ red/ white (alphabetically) you will always configure the wiring properly.
When you get to the speakers,black/ green will be for one speaker,and red/
white will be for the other.Most common wiring errors can be attributed to not
following a standard colour pattern.
Since you will be cutting this cable at the keypad location to perform the connections it is a
good idea to mark the cable with a permanent marker to identify where the other end goes.
If the cable is run behind a wall,you may need to use your ohmmeter to help determine which
end of the cable goes in which direction.
Common Equipment
Place all the common audio equipment on individual shelves.Stacking equipment is not
recommended as this presents situations in which airflow may be restricted,or component
cooling is impaired.Audio equipment sources,and the MRC- 8e/ 8.4e do generate small
amounts of heat that must be dissipated to extend component life.
Equipment should have adequate room on all sides for proper air circulation and heat
dissipation,as well as room for all the cables to reside.If rear access,or a rack mounted
structure has beenprovided,then cable installation will be much easier.
