Connecting Your Subwoofer
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 page 7. Please consult your 
processor/receiver manual for further information.
WARNING: To prevent risk of electrical shock or damage to your 
equipment, always unplug all component AC cords before pro-
ceeding with speaker and component connections! The last step in 
wiring your system should be plugging in the AC cords!
Subwoofer Line Out to Low Level In
Run an RCA cable from your receiver’s Sub Out jack to the L/Mono input 
jack on the back of the subwoofer (Figure 3). If your receiver/processor 
has stereo subwoofer outputs, connect these to both the L/Mono and R 
jacks on the back of the subwoofer (Figure 4).
Using the Low Level Output
If desired, you can run a low level signal through the subwoofer and out 
to another unit. This way you can add an additional subwoofer with mini-
mal additional wiring. The signal that comes out of the output jacks is 
identical to the input signal.
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 Tech-
nology does not recommend plugging 
the subwoofer into the switched outlet 
of an amplifier, preamplifier, or receiver. The power demands of the sub-
woofer amplifier may exceed the power rating of the switched outlet and 
may damage the equipment.
Figure 2
 AC Connection
Your subwoofer is totally automatic in its operation. The automatic on/
off circuitry will only activate the subwoofer in the presence of an audio 
signal from your system. After 7-10 minutes with no signal detected from 
the rest of the system, the amplifier will shut itself off and go back into 
standby mode. When the sub is in operating mode, the status LED will 
glow green. The LED will glow amber in the Standby mode and power 
consumption in this mode is negligible. Standby operation can be com-
pletely bypassed by placing the standby switch on the rear panel to the 
ON position.
