for long periods of time.

14. Refer all servicing to qualified service personnel. Servicing is

required when the apparatus has been damaged in any way, such

as power supply cord or plug is damaged, liquid has been spilled

or objects have fallen into the apparatus, or the apparatus has

been exposed to rain or moisture, does not operate normally or

has been dropped.

15. Do not expose this apparatus to dripping or splashing and

ensure that no objects filled with liquids, such as vases, are

placed on the apparatus.

fire or the like.

The lightning flash with arrowhead symbol, within

an equilateral triangle, is intended to alert the

user to the presence of uninsulated “dangerous

voltage” within the product’s enclosure that may

be of sufficient magnitude to constitute a risk of electric shock

to persons.

The exclamation point within an equilateral

triangle is intended to alert the user to the

presence of important operating and mainte-

nance (servicing) instructions in the literature

accompanying the product.

PLACEMENT

Since the installation of a subwoofer can be somewhat more complicated

than installation of full-range speakers, it is essential that you read this section

very carefully prior to connecting the subwoofer to your system. Should you

have questions relating to your installation, it is advisable to call your dealer or

distributor for advice.

The performance of the subwoofer is directly related to its placement in the

listening room and how you align the subwoofer with its satellite speakers.

Setting the volume of the subwoofer in relationship to the left and right speakers

is also of critical importance because it is essential that the subwoofer integrate

smoothly with the entire system. Setting the subwoofer’s volume level too high

will result in overpowering, boomy bass. Setting the volume level too low will

negate the benefits of the subwoofer.

Here are several additional facts on installation that may prove useful.

It is generally believed by most audio authorities that low frequencies (below

125Hz) are nondirectional and, therefore, placement of a subwoofer within

any listening room is not critical. While in theory it is true that the larger wave-

lengths of extremely low frequencies are basically nondirectional, the fact

is that, when installing a subwoofer within the limited confines of a room,

reflections, standing waves and absorptions generated within the room will

strongly influence the performance of any subwoofer system. As a result,

specific location of the subwoofer becomes important, and we strongly recom-

mend that you experiment with placement before choosing a final location.

Placement will depend upon your room and the amount and quality of bass

required (for example, whether or not your room permits placement of the

subwoofer near either satellite).

Figure 1. This example shows the subwoofer positioned behind

the right-channel satellite speaker to re-create the actual location

of bass instruments in an orchestra and/or add impact to movie

soundtracks.
