When you use this low-level input to the subwoofer, it is very important to disconnect (on the speaker(s)) the gold jumper going between the + (red) mid and low, and - (black) mid and low 5-way binding posts. (There should be nothing connected to the 5-way binding posts labeled low.) Hook up your high (speaker) level signal as you would normally between your center channel amplifier terminals to the corresponding center speaker + mid terminal and - mid terminal. Do the same for all your speakers. (See diagram # 4.) If you wish to bi-wire your speaker(s) (see diagram # 5) as well as use the low-level inputs (if you want absolutely the ultimate hook-up method, this is it), simply remove all gold jumpers on the speaker(s) and run separate sets of speaker cable to the mid and high terminals of the speaker(s) as described under bi-wiring as well as a separate RCA low-level cable from the center channel low-level output on your receiver, pre-amp or decoder into the full-range low-level input, as described previously. Remember, when using this low-level subwoofer input, there should never be any wire or jumper connected to either of the 5-way binding posts labeled "Low" on either speaker. In order to achieve optimum performance, maintain perfect driver blending and take full advantage of the benefits of having a built-in subwoofer, it is important, if you are using lowlevel "Full Range Inputs" to drive the subwoofer, that you use full range center channel lowlevel signals to feed this input, NOT, REPEAT, NOT SUBWOOFER LFE OUTPUT SIGNALS.
