Note

There may be a case that you cannot obtain enough

super-bass sounds from the subwoofer when listening

in the center of the room. This is because “standing

waves” have developed between two parallel walls and

cancel the bass sounds.

In such a case, place the subwoofer at an oblique angle

to the wall. It also may be necessary to break up the

parallel surfaces by placing bookshelves, etc. along the

walls.

ADJUSTING THE SUBWOOFER BEFORE USE

Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer

and the front speakers by following the procedure described below.

1 Set the VOLUME control to minimum (0).

Notes

2 Turn on the power of all the other components.

• Once the volume balance between the subwoofer and

the front speakers is adjusted, you can adjust the

characteristics” on page 13.

5 Adjust the HIGH CUT control to the position where

the desired response can be obtained.

Normally, set the control to a level a little higher than

the front speaker’s rated minimum reproducible

frequency*.

* The front speaker’s rated minimum reproducible

frequency can be looked up in the speakers’ catalog

or owner’s manual.

6 Increase the volume gradually to adjust the volume

balance between the subwoofer and the front speakers.

Set the control to a level where you can obtain a little

more bass effect than when the subwoofer is not used.

If the desired response cannot be obtained, adjust the

HIGH CUT control and the VOLUME control again.

7 Set the PHASE switch to the position which gives you

the better bass sound.

Set the switch to the REV (reverse) position. If the

desired response cannot be obtained, set the switch to

the NORM (normal) position.
