INTRODUCTION
Proficient's PS12, PS10 and PS8 Powered Subwoofers add accurate bass to any audio system, and are designed to work in conjunction with your other audio
components. The PS12 / PS10 / PS8 can be connected to any surround sound receiver that has a subwoofer output or any receiver that has a built-in preamplifier
outputs.
PLACEMENT
For optimal performance, the PS12 / PS10 / PS8 should be placed in a corner along the same wall as the front speakers. The units are not shielded, so do not
place them too close to video devices. When choosing a place for the PS12 / PS10 / PS8, please keep the following in mind:
DO
• Place the PS12 / PS10 / PS8 with its feet resting on a solid flat level surface.
• Place the PS12 / PS10 / PS8 in a well-vented area to provide proper cooling. In areas that lack proper ventilation, such as tight cabinets or racks, it may b e
necessary to install small fans to create air movement.
DON'T
• Obstruct the driver or ports of the PS12 / PS10 / PS8 as that will hinder performance.
