Subwoofer Adjustment & Use
Subwoofer initial control settings
•Set the LOW PASS FREQUENCY Control to its center position.
•Set the LEVEL Control fully counterclockwise to MIN. You’ll reset this control after you make other adjustments.
Adjusting the Subwoofer controls
•Play a program on your system. Use a Dolby® Digital or Dolby® Pro- logic signal, or a music CD. Adjust the Receiver’s volume control for a comfortable sound level from the system speakers.
•Increase the Subwoofer’s LEVEL Control setting clockwise, so that you hear the deep bass. Adjust the control for a natural, musical balance that has plenty of deep bass sound when it’s actually present in the music.
•Listen carefully to bass voices and, if needed, adjust the LOW PASS FREQUENCY Control so that they sound natural. Setting the frequency too high will make deep voices sound excessively “chesty” or resonant and will give the upper bass in music a “one-note” quality. Setting the frequency too low will make deep voices sound “thin” and will give music a lack of “warmth.”
•Adjust the Phase Control for maximum bass response. The phase control can help to align the bass of the Subwoofer with the bass response of other speakers in the system. Listen to a piece of music with the Phase Control in one setting. Change the setting on the switch and listen for an increase or decrease in the bass response. One setting should produce better bass response. If there is no change, then your subwoofer and speakers are aligned properly in either position.
•Make fine adjustments until the program has satisfying and natural sound quality on both bass voices and music.
Troubleshooting
Subwoofer POWER Indicator LED does not light
•Check that the Subwoofer’s POWER switch is in the AUTO ON position.
•If the POWER Switch is in the AUTO ON position, check the AC outlet the Subwoofer is plugged into to be sure that it is live. You can use a tester or plug in a lamp to check it.
•If the AC outlet is live, either the power cord or Subwoofer has a problem. Unplug the power cord from the AC outlet and check the fuse by unscrewing the center piece from the holder. If it is blown, replace the fuse only with a fuse of the same type and rating. If this doesn’t help, take the Subwoofer to your dealer for service — THERE ARE NO USER-SERVICEABLE PARTS INSIDE.
No sound from the Front speakers
•Be sure the Receiver and Subwoofer POWER switches are in the ON positions.
•Check the Receiver’s Volume Control setting — if it is all the way down, there won’t be any sound.
•Check that the Receiver’s Input Selector is set to an active source of audio signals and that a Tape Monitor Loop is not engaged.
•Be sure that the Receiver’s Speaker Selector switch is turned on to the terminals [A or B, 1 or 2] that you have your Front speakers connected to. If the Receiver has a headphone jack, you can use headphones to check the Receiver for output.
•Check the wires and connections from the Receiver’s Front Speaker Output terminals to the Subwoofer’s SPEAKER-IN
terminals.
•Try removing the Subwoofer from the system, leaving your Front speakers connected to the Receiver. If there still is no sound, take the Receiver to your dealer for service.
•Try removing the Subwoofer from the system, leaving your Front speaker connected to the Receiver. If there still is no sound, take the Receiver to your dealer for service.
No sound from the Subwoofer
•First, be sure there is sound from the Front speakers and that the Receiver is working correctly as outlined above.
•Check the Subwoofer’s LEVEL control. If it is all the way counterclock- wise, there may be no sound.
•The Subwoofer only reproduces deep bass sound. If the program has no deep bass, the Subwoofer will not make any sound. Play a program with plenty of bass, such as jazz or rock music, or an action movie.
•If everything else checks OK, take the Subwoofer to your dealer for service - THERE ARE NO USER-SERVICEABLE PARTS INSIDE.
