System Installation
There will most likely be a number of cables involved in the installation of your home
entertainment system. Preplanning is essential in order to maximize system efficiency.
We recommend the following as a means of helping you reach that goal:
§
Make a diagram of your proposed system by laying out the relative location of each
component in the system. Then lay out the proposed cable runs between them.
Number each cable and record its length on the diagram for future reference.
§
Cable runs are critical in that they must be kept away from sources of power
radiation (amplifiers, power cords, heaters, etc...). For safety reasons, they
should also be kept out of traffic areas.
§
The process of optimizing the system will include the type of cable, the length of the
run, and the obstructions it must deal with along its run. Your dealer can advise you
on the products available and their relative merits. If building custom length audio
cables is not your strength, your dealer should be able to help you with that as well.
§
When possible, use a separate AC power line for the amplifier, one that is not
shared by any other household component.
Important!
Tip: Take a piece of string (longer than the longest cable run) and mark it at each foot of length. Then do a
mock cable run using the string, dressing it neatly along the way. Count the divisions to the next full foot,
and add one foot to allow for some movement of the components. This will provide you with the ideal cable
length.
Making the connection
§
Before doing anything, insure that the power switch on the amplifier’s front panel is
in the ‘off’ position.
§
Again, it is recommended that you locate a separate AC power outlet for the
amplifier, one that is
not
shared by any other audio component in the system or
any other house hold component. This will eliminate the possibility of the
amplifier ‘modulating’ the power being supplied to the component and
compromising the signal originating from that component.
§
Locate the AC power cord provided with the amplifier and plug it into the power
input receptacle in the rear panel.
Do not connect it to the AC power source yet!
§
Connect the audio cables from your preamplifier’s output to the corresponding input
connector on the amplifier.
