SYSTEM INSTALLATION

7

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.

•When possible, use a dedicated AC power line for the amplifier, one that is not shared by any other household component. THIS IS VERY IMPORTANT!!

•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.

•Cable runs are critical in that they must be kept away from the sources of power radiation (ampli- fiers, power cords, heaters, appliances, etc.). For safety reasons, they should also be kept out of traf- fic 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 cable is not your strength, you dealer should be able to help you with that as well.

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 all for some movement of the components. This will provide you with ideal cable length.

MAKING THE CONNECTION

Refer to back panel on page 4

•As a precaution, insure that the power switch on the amplifier's front panel is in the 'off' position and AC power is disconnected before making any connections.

•Connect the wires from your speakers to the appropriate output channels on the amplifier. It is essential that correct polarity is observed in all connections.

•Connect the audio cables from the preamplifier's audio outputs to the amplifier input channels using either balanced (XLR) or unbalanced (RCA) interconnects.

Example: Connect Front Left output of the preamplifier to channel 1 of the amplifier, connect the Front Left speaker wires to channel 1's outputs. Always observe polarity when connecting speakers, i.e. amplifier

(+)RED to the speaker (+) RED and amplifier (-) BLACK to speaker (-) BLACK.

•Double-check all connections.

•It is recommended that a dedicated AC power outlet is used for the amplifier, one that is not shared by any other audio or household component.

•Locate the AC power cord provided with the amplifier and plug it into the power input receptacle in the rear panel. Make sure front panel power switch is off (out). Do not connect to the AC power until speaker connections are complete!

•Connect a playback unit (CD, DVD, SAT, Tuner, etc.) to the preamplifier. Turn on the preamplifier, turn the volume on the preamplifier to a minimum level, and then turn on the amplifier using the power switch on the front panel (in this order). Set the source on the preamplifier to the playback unit con- nected. Turn the volume up slowly and listen for music from all channels.

If a problem is encountered that cannot be traced to the hardware connections or to the material being played, consult the "TROUBLESHOOTING" section on page 9.

Note: If the control triggers are not being used, the amplifier should always be turned off first, then the preamplifier.

Before turning anything on, insure the preamplifier is at a low volume level.
