SPEAKER PLACEMENT

Proper placement of the speakers is an important step in obtaining the most realistic soundstage possible. These recommendations are for the optimum placement of the

loudspeakers. Use these placement recommendations as a guide. Slight variations will not diminish your listening pleasure.

The Studio Series S-CENTER loudspeaker is video-shielded and can safely be placed near a television.

The S-CENTER is designed to complement all of the Studio Series loudspeakers. It is the ideal way to re-create the cinematic experience in your home.

SPEAKER CONNECTIONS

CONNECTION TIPS

Diagram of two parallel conductors with shaded insulation, placed on grid paper (no text or symbols)

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.

Speaker Outputs

TROUBLESHOOTING

If there is no sound from any of the speakers:

• Check that receiver/amplifier is on and that a source is playing.
• Review proper operation of your receiver/amplifier.

If the system plays at low volumes but shuts off as volume is increased:

- Check all wires and

connections between receiver/amplifier and speakers.

• Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured.
- If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier.

If there is no sound from the center speaker:

• Make sure that your receiver's "Center-Channel" mode is in the "Normal" or "Wide" position. If it is in the "Phantom" position, the center speaker will not play.
• Check all connections between processor/amplifier and the center speaker.
