4)If your receiver/ampli- fier has preamp output jacks and main input jacks for the left and right channels, or you have a separate preamp/ processor and

power amplifier.

This method of hookup can offer the highest level of performance for your complete loudspeaker system. The PSW-D112 incorporates a variable high-pass crossover in addition to a variable low-

pass crossover. When hooked up as shown, the subwoofer will limit the low-frequency information that is returned to your receiver/amplifier. Your receiver/amplifier does not need to waste valuable power reproducing the low frequencies. In addition, since no low-frequency information is being sent

to your main loudspeakers, they are able to reproduce mid and high frequencies with greater clarity.
