MODELS: N24II, N24AWII, N26AWII, N-CENTERII The supplied self-adhesive felt pads may be attached to the bottom corners of your speakers to protect your furniture. Place pads here SPEAKER CONNECTIONS CONNECTION TIPS 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 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 colored collar until the pass-through 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 bananatype connectors.

TROUBLESHOOTING If there is no sound from any of the speakers: · Check that receiver/amplifier is on and that a source is playing. If there is no sound coming from one speaker: · Check the "Balance" control on your receiver/amplifier. · Check all wires and connections between receiver/amplifier and speakers. Make sure no wires are touching other wires or terminals and creating a short circuit. [. . . ] If there is no sound from the center speaker: · Check all wires and connections between receiver/amplifier and speaker. · If your receiver/processor is set in Dolby Pro Logic* mode, make sure the center speaker is not in phantom mode. · If your receiver/processor is set in Dolby Digital or DTS mode, make sure the receiver/ processor is configured so that the center speaker is enabled.
