Switch Modes for TH812, TH221, TH412, and DBH218
These subwoofers can be run two ways; Bi-amp or passive. In the passive mode, the connection is to pins +1 and -1. Pins +2 and
-2 pass through from one NL4 to the other. In Bi-amp mode connect one amp channel to pins 1+ and 1- of the NL4, and the other
channel to pins 2+ and 2-. If four conductor cable is not available, you may use two runs of two conductor cable.

In the biamp mode the average impedance of the woofers will be twice the passive mode.

Rigging
If you have to ask how, you probably shouldn’t be doing it!
