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 chan- nel 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 hookup method, this is it), simply remove all gold jumpers on the speaker(s) and run sepa- rate 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-rangelow-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 low- level “Full Range Inputs” to drive the subwoofer, that you use full range center channel low- level signals to feed this input, NOT, REPEAT, NOT SUBWOOFER LFE OUTPUT SIGNALS.
