Model 642e SB Powered 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 642e SB (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 642e SB (Figure 4).
Using the Low Level Output
If desired, you can run a low level signal through the 642e SB 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 acciden-
tally activating the subwoofer while
wiring. Atlantic Technology does not
recommend plugging the subwoofer
into the switched outlet of an ampli-
fier, preamplifier, or receiver. The power demands of the subwoofer ampli-
fier may exceed the power rating of the switched outlet and may damage
the equipment.

The 642e SB 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 power LED
located under the front grille will glow green. The LED will glow yellow
in the Standby mode and power consumption in this mode is negligible.
Standby operation can be completely bypassed by placing the switch on
the 642e SB amplifier to the ON position.
