4)If your receiver/ampli- fier has preamp output jacks and main input jacks for the left, center and right channels, or left and right channels only, 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 and PSW-D115 incorporate a variable high- pass crossover in addition to

a variable low-pass crossover. When hooked up as shown above, the subwoofer will limit the low-frequency infor- mation 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.
