MAINTENANCE AND SERVICE
Because of Phase Technology’s uncompromising quality control programs, it’s unlikely that your speakers will ever need
service if connected and used as outlined in this Owners’ Manual. In the unlikely event that a problem does occur, please
contact your Phase Technology dealer. Your dealer has the necessary factory-authorized parts and trained technicians to
quickly restore your speaker to its original performance specifications.
TROUBLESHOOTING
No sound
1.
Verify that all components are plugged in and turned on.
2.
Check all speaker wires and cables for loose connections.
3.
Check to see if you have selected the proper source on your amplifier.
Voices do not appear to come from between the speakers / bass response is weak
1.
Verify that all speaker connections from the amplifier to the speakers are running PLUS+ to PLUS+ and MINUS- to
MINUS-.
2.
Check to see if there are any furnishings or plants that may be blocking the output of a speaker. Make sure nothing
is directly in front of that speaker.
Sound, but no bass (most likely in systems with a subwoofer)
1.
Verify that the subwoofer is plugged into an AC outlet and power is turned on.
2.
Check that the speaker wire / cable going from the amplifier/receiver to the subwoofer is securely fastened.
3.
Check the volume control of the subwoofer.
4.
Refer to your amplifier/receiver manual to make sure you have adjusted its bass output properly.
Muddy or boomy bass
1.
Check the volume control for the subwoofer. Excess volume can cause speakers to sound distorted and
unnatural.
2.
Try adjusting the crossover control on the subwoofer (or the subwoofer setup on your receiver) to a slightly
lower frequency (example: reduce from 120 Hz to 80 or 60 Hz).
3.
If the subwoofer or full size speaker is close to a corner, side or back wall, try moving it away from the wall.
This may reduce the “boomy” bass considerably.
4.
Bookshelf speakers placed in a semi-enclosed space or cabinet can artificially emphasize bass output.
Reduce the bass control on your amplifier or move the speakers to the front of the cabinet. Alternatively,
reposition the speakers to a more open location.
Distorted sound from the speakers
1.
This problem is usually caused by setting the volume control too high. Reduce the amplifier/receiver volume
to a lower level.
2.
If noise and distortion are audible at higher volume levels, your amplifier may not be powerful enough.
Consider upgrading to a unit with higher power.
NOTE: Remember, even though your Phase Technology speakers can handle considerable power levels, ANY speaker if used
improperly can be damaged. Consult your Phase Technology dealer for assistance in choosing a new amplifier or receiver.
