Speaker Out/

High Level In for

Stereo

Subwoofers

This is the most
common method
for connecting 2
subwoofers to a
system without a
dedicated sub-
woofer line out or
Preamp outputs.
Note that the
L/MONO High
Level input is used
on both left and
right subwoofers.
You can connect to the High-level inputs by removing 1/2" of insulation from each wire end, twisting
the strands of wire together and placing the wire into the appropriate binding post on the rear of the
woofer as illustrated. Be careful that no stray strands of wire touch across connections.
It is important to observe polarity while making speaker connections: red (+) terminals on the ampli-
fier to red (+) on the speaker, black (–) on the amplifier to black (–) on the speaker. Look carefully at
the wires you are using and note that one of the wires in each pair will be marked by either the con-
ductor color, printing on the wire jacket, a ridge on one side of the wire jacket, or a thread intertwined
with the wire strands. By convention, the marked wire is connected to the red (+) terminal.
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.
The T70.1 PBM 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 audio/video system. After 7-12 minutes
