ACCESSORIES
When unpacking the speaker, first check to make sure that all of the accessories listed below are supplied.
. RCA cord
(Pin plug e Pin-plug)
Use to connect S-DW1-K to an amplifier or receiver.
INSTALLATION
Sound spreads in all directions in the very low frequency
range. Human hearing cannot easily detect the source of
these very low frequencies. Therefore, the placement of the
subwoofer is not critical. Howeve[ maximum bass is achieved
with a corner location of the subwoofer, or at location "A".
IN COMBINATION WITH SPEAKERS
The frequency characteristics of S-DW1-K combined with
small-size speakers are shown below. As shown in these
figures, the low frequency range is improved when combined.
. These special characteristics are obtained in the echoless
chamber. The effect of an additional S-DW1-K in an ordi-
nary listening room is more than this when positioned ad-
equately.

O Subwoofer LEVEL knob
Volume of subwoofer is adjusted with this knob. Turn this
knob clockwise to raise the level.
. Starting at "MlN", turn this knob and raise the volume
slowly. lf the unit is turned on with the volume set too high,
it could cause hearing and/or speaker damage. Do not
turn the volume up excessively high. The low frequency
sound is apt to be raised too high since it is less disturb-
ing and harder to detect than high frequencies. Gaution
must be taken here since the amplifier and speaker of the
S-DW1-K will be clipped when the output of the amplifier
or receiver is increased with the subwoofer level set to
"MAX".
@ PHASE selector switch
This switch changes over the subwoofer phase [0o (in-
phase), 180o (opposite phase)l for the combination speak-
ers. Set this switch to suit your choice of bass, according to
the location of the subwoofer.
@ FREQUENCY control knob
Select the position according to the woofer level of the
speaker to be combined.
50 Hz ... For large-sized speaker
(woofer diameter: 8 inch or more)
100 Hz ...For middle-sized speaker
(woofer diameler: 5 to 10 inch)
150 Hz ...For small-sized speaker
(woofer diameter: 5 inch or less)
@ POWER switch
@ Subwoofer input terminals
(HrGH LEVEL rNPUT)
Connect the speaker output terminals of amplifier or receiver
to these terminals with the accessory parallel-wire cord.
@ Speaker output terminals
(HrGH LEVEL OUTPUT)
Connect the satellite speaker input terminals to these termi-
nals with the two parallel-wire cords. When the SPEAKER
LEVEL INPUT is in use.
@ Subwoofer input terminal
(LOW LEVEL rNPUT)
Connect SUBWOOFER output terminal of the amplifier or
receiver to this terminal with the accessory RCA cord.
@ Subwoofer output terminal
(LOW LEVEL OUTPUT)
Used for connecting an additional subwoofer to the system.
Connect this terminalto the SUBWOOFER INPUT terminal
of another subwoofer.
lf the output of the amplifier (receiver) connected to this
unit is high or if the output has a low range boosted by the
Bass control, Bass boost, or other means, there may be
some sound distoilion even if the level of the unit is low-
ered. ln this case, lower the output level (Volume, Bass
control, Bass boost) on the amplifier (or receiver) side.

CONNECTION
Connection with a normal audio system
Connect the speaker output terminal of your amplifier or receiver with two parallel-wire cords.
NOTES:
. Connect the amplifier (or receiver) and the S-DWI -K and the speaker systems so that the polarities (L & R, @ A O) between
them are correctly connected.
. When operating near your speaker system, feedback may occur when the power supply of the amplifier (receiver) or the
speaker switch is turned OFE or if the subwoofer level is set too high.
Beware of the following, as the subwoofer may be damaged by feedback:
1. lf possible, connect the power cord of the S-DWI-K to the switched outlet of the amplifier.
2. ln the case of amplifiers or receivers without a switched outlet, be sure to decrease the level of the subwoofer before
turning the power supply of the amplifier or the speaker switch OFE
. A buzzing noise may occur when the speaker switch of the amplifier or receiver is turned off or the power supply is discon-
nected and the subwoofer level is set too high. This is not a failure, so once more connect the power supply to the receiver and
turn the speaker switch on to remove the noise. Lower the subwoofer level when the subwoofer is not in use.
CONNECTION 1
1. Connect the amplifier or receiver speaker output
terminals to the S-DW1-K HIGH LEVEL ]NPUT ter-
minals with the two parallel-wire cords of the audio
system.
2. Connect the S-DW1-K HIGH LEVEL OUTPUT ter-
minals to the speaker system, using the two paral-
lel-wire cords.
NOTE:
Use speakers with a rated impedance which corresponds with the
indicated impedance at the rear panel of the amplifier or receiver.

cord together and connect again. Make sure that two cords
are connected to the speaker terminals. Amplifier or receiver
S.DW1-K
NOTE:
ll your amplifier or receiver has two pairs of speaker outputs (A, B),
the two parallel-wire cords may be connected to a terminal other
than the terminal already connected. ln this case, set the speaker
switch to "A + B" "A, 8". But the speakers will not operate normally if
they are connected to a receiver or amplifier with terminals A and B
connected in series.

Dean &alupo:
Selecting fine audio equipment such as the unit you've just
purchased is only the start of your musical enjoyment. Now it's time
io consider how you can maximize the fun and excitement your
equipment offers. This manufacturer and the Electronic Industries
Aisociation' s Consumer Electronics Group want you to get the most
out ofyour equipment by playing it at a safe level. One that lets the
sound-come ihrbugh loud and clear without annoying blaring or
distortion-and, most importantly, without affecting your sensitive
hearing.
Sound can be deceiving. Over time your hearing "comfort level"
adapts to higher volumes of sound. So what sounds "normal" can
actially be lbud and harmful to your hearing. Guard against this by
setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
. Start your volume control at a low setting.
. Slowly increase the sound until you can hear it comfortably and
clearly, and without distortion.
Once you have established a comfortable sound level:
o Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing
damage or loss in the future. After all, we want you listening for a
lifetime.
I
We Want You Listening For A Lifetime
Used wisely, your new sound equipment will provide alifetime of
fun and enjoyment. Since hearing damage from loud noise is often
undetectable until it is too late, this manufacturer and the Electronic
lndustries Association's Consumer Electronics Group recommend
you avoid prolonged exposure to excessive noise. This list of sound
levels is included for your protection.
