Connecting Your Subwoofer
Use the low-level (RCA jack) subwoofer line out of
your surround sound receiver/processor. Simply
connect your subwoofer with a high quality shielded
cable as shown in the diagram on the opposite page.
Please consult your processor/receiver manual for
further information.
Warning: To prevent risk of electrical shock or
damage to your equipment, always unplug all com-
ponent AC cords before proceeding with speaker
and component connections! The last step in wiring
your system should be plugging in the AC cords!
AC Connection To SBT-1000
(SBT-500 is similar)
Normal Operation
With the Standby switch in the AUTO position,
the subwoofer turns on in the presence of an audio
signal from your system. After 7-10 minutes with no
audio signal detected, the amplifier enters its low-
power draw Standby mode. Standby operation can
be bypassed by putting the switch in the ON posi-
tion. The OFF position inactivates the subwoofer.
When the sub is on, the power LED located on the
amplifier panel glows green. The LED glows yellow
in the Standby mode. The LED is dark if the Stand-
by switch is set to OFF.
Subwoofer Line Out to Low Level In
Run an RCA cable from your receiver’s Sub Out jack
to either the L (
LEFT CHANNEL
) input jack or R (
RIGHT
CHANNEL
) input jack on the back of the powered sub-
woofer. If your receiver/processor has stereo subwoof-
er outputs, connect these to the L (
LEFT CHANNEL
) and
R (
RIGHT CHANNEL
) jacks on the back of the powered
subwoofer.
Power Connection
Connect the power cord to an AC outlet only after
making all other connections to the subwoofer. This
will avoid any chance of accidentally activating the
subwoofer while wiring.
Atlantic Technology does not recommend plugging
the subwoofer into the switched outlet of an amplifier,
preamplifier, or receiver. The power demands of the
subwoofer amplifier may exceed the power rating of
the switched outlet and may damage the equipment.
