The process of optimizing the system will include the type of cable, the length of
the run, arxl 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 component in the system of any other house hold
component.
Tip: Take a piece of stout 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, ensure that the power switch on the amplifier’s front panel
is in the ‘off’ position (rocker side in towards center of amplifier). 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. (Refer to Diagram 1)
Connect the wires from your speakers to the appropriate (R,L) output on the
amplifier. It is absolutely essential that you observe correct polarity in these
connections. (Refer to Diagram 1)
Example: If you connect your right front output of your preamplifier to channel 1
input on the amplifier, remember to connect your right front speaker wires to channel
1‘s outputs. Aiways observe poiarity when connecting speakers, connect ampiifiers
(+) to the speakers (+) and amplifiers (-) to speakers (-)
Double check all connections.
