Left and Right speakers and to your
subwoofer by turning the subwoofer
output “Off” and setting the Main
Left and Right speakers to “Large”.
This blends all the output of the
Low Frequency Effects channel with
the Main Left and Right speakers.
The
Powered Subwoofer
needs to be
connected with speaker wire to the
Main Left and Right speaker outputs
in this case.
AC Power, Etc.
After making the audio connec-
tions, plug the power cord into any
convenient 120-Volt AC, 60 Hz
outlet and switch the subwoofer
“On”. Do
not
plug it into a switched
outlet on your amplifier or receiver,
as the
Powered Subwoofer
draws
sufficient current at high volume
levels to possibly damage the
switched outlet’s relay mechanism.
NOTE:
If you connect the
Powered
Subwoofer
to your system using
speaker wires and hear a low-level
hum, turn off both the system and
the subwoofer and reverse the
latter’s AC plug in the outlet.
When you turn the system back
on, the hum should be gone.
The
Powered Subwoofer
has an
automatic “Power Off” circuit that
turns off power to the amplifier
circuit after it has been silent for over

silver colored wire to the black
(negative) connector.
• Connect the opposite end of the
speaker wire to the
Slave
Subwoofer
input connector in a
similar fashion.
• The information about place-
ment on pages 5 and 6 also
applies to the combination of a
Slave Subwoofer
and

convenient to place the two
units right next to each other
and treat them as one, they

when they are placed several

20 minutes. The
Powered Subwoofer
rapidly activates as soon as a new
signal is present. This feature oper-
ates when the switch labeled “Auto-
off Setting” is in the “Auto” position.
Most home users will find this
setting to be appropriate.
The “manual “ position of the
“Auto-off Setting” switch keeps the
amplifier operating and drawing a
small current so long as the Power
switch is in the “On” position. This
setting is appropriate when the
Powered Subwoofer
is used in pro-
fessional sound studios.
AC Power Light
The light next to the Power
Switch glows in different colors to
reflect the operating status of the
amplifier. Green indicates the
Powered Subwoofer
amplifier is
“On” and operating. Amber means
the
Powered Subwoofer
amplifier is
in “Standby” mode and will
power-up and operate as soon as a
signal is fed to it. Red indicates an
amplifier-fault condition. See page
10 if this occurs. The light goes
dark when the Power switch is in
the “Off” position. The
Powered
Subwoofer
amplifier is discon-
nected from the AC line in this
condition.
The
Slave Subwoofer
connects to the
Powered Subwoofer
with the sup-
plied 25 foot 16-gauge speaker
cable (or any other high quality
heavyweight speaker cable).
• Using the supplied wire strippers,
remove
1
/

inch of insulation from
the copper and silver colored
wires at each end of the speaker
wire. Twist each exposed lead’s
fine wire strands tightly together.
• Remove the cover from the
“SLAVE SUBWOOFER OUTPUT”
on the back of the
Powered
Subwoofer
. Connect the copper-
colored wire at one end of the
speaker cable to the red (positive)
connector on the
