No signal connection cable is provided with the P-1200 subwoofer since the type and length of cable is installation
specific. A shielded RCA type coaxial cable, a shielded two-conductor wire with RCA type connectors, or a
2-channel speaker cable is required for connection of the P-1200 to the audio system. Ensure sufficient length to
reach from the system source to the subwoofer’s line or speaker level input. If you are uncertain about the type
and length of wire to purchase after reading this section and the section on Placement then please contact your
dealer for assistance.
Before making any connections, ensure that power cord is disconnected or that the main power switch is switched
to the off position.
Input Signal: Follow the diagram on page 7 for connecting the subwoofer to your audio system. Use the option
that best suits your installation. WARNING: Use only one of the three options, (Do Not Combine Options).
The information below will aid in determining which option to use.
Note: The best performance can be achieved using the line level inputs ( or ) as opposed to
the speaker level inputs ( ).
