CONNECTION TIPS
amplifier. Wiring �out of phase� results in thin sound, weak bass and a poor stereo image. With the advent of multichannel surround sound systems, connecting all of the speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material. To use the binding-post speaker terminals, unscrew the collar until the passthrough hole in the center post is visible under the collar. Insert the bare end of the wire through this hole; then screw the collar down until the connection is tight. The hole in the center of each collar is intended for use with banana-type connectors.

Speakers and electronics terminals have corresponding (+) and (�) terminals. It is important to connect both speakers identically: (+) on the speaker to (+) on the amplifier and (�) on the speaker to (�) on the

Receiver�s Speaker Outputs

Your S412PII speakers should be connected to your receiver in two ways (at speaker level and line level) in order to achieve the best performance, especially when listening to program material recorded in digital formats, such as Dolby* Digital and DTS.® Connect the left-front and right-front speaker terminals on your receiver or amplifier

to the 5-way binding posts on the back of each S412PII speaker. Remember to maintain the correct polarities (�+� to �+� and ��� to ���). The S412PII uses a red binding post for �+� and black for ���. These connections will provide full-range sound to all four transducers, and you should ALWAYS make these connections.

If your receiver or amplifier does not have a line-level subwoofer output, then you do not need to make any other connections, and you should skip to the section titled �Amplifier Controls.�
