back of the networks provide three set-

tings (zero, plus, and minus) so that the systems can be trimmed for the acoustical characteristics of the listening space.

Regardless of the operating mode you choose, we recommend that only the ﬁnest hookup wire be used between the ampli- ﬁers and dividing networks. We recommend that the wire size be no smaller than 3.3 square millimeter cross-section (#12 AWG). The inputs to the networks can accommodate spade lugs, pins, bare wire, or individual banana connectors.

The internal 9-volt battery that is used to bias the capacitors will normally last at least 5 years. You may test it by pressing the gold logo on the front of the network. If the LED on the front of the network illuminates, the battery is functional and need not be replaced.
