G. TROUBLESHOOTING & SERVICE
Before returning your NX-PROSUB125/NX-PROSUB300 for service,
you can save time (and often embarrassment) by checking for a few
problems that are most often encountered.
Power light is not lit. No sound.
1. Is your NX-PROSUB125/NX-PROSUB300 plugged in to a live AC
wall socket?
2. Is the power switch on?
3. Has the NX-PROSUB125/NX-PROSUB300 overheated and shut
off temporarily?
4. Is the fuse OK?
No sound from either set of speakers.
1. Are your other components turned on?
2. Is the receiver or preamp set to the appropriate input and is
that sound source playing?
3. Do you have an unconnected tape monitor selected?
4. Is the NX-PROSUB125/NX-PROSUB300 correctly connected to
your receiver, preamplifier or integrated amplifier and turned on?
Sound comes from main speakers but not subwoofer
1. Is the NX-PROSUB125/NX-PROSUB300 turned on (power light
in the green mode) and VOLUME control turned up?
2. Check the speaker connections for small strands of wire
touching both terminals.
3. Some digital receivers only send a sub out signal when in the
movie or digital mode. In the 2 channel (stereo music) mode, no
sub out signal is sent to the sub.
You may need to set your main speakers to “small” mode in your
receiver setup to get the receiver’s subwoofer output to turn on.
Check your receiver’s owner’s manual for subwoofer operation.
4. For digital receivers – make sure the subwoofer is “ON” and
the subwoofer level is set to “0 dB” or greater.
Sound comes from the subwoofer but not your main speakers
1. If you have used either version of Hookup Method A, check
the connections between your receiver and your main or satellite
speakers.
2. If you have used Hookup Method B (Line Level)...
• confirm that the power amplifier is turned on.
• check the RCA patch cord
• check the speaker wire connections between the receiver and
main or satellite speakers.
Bass is muffled or weak
1. Check speaker wire polarity of all connections.
2. Reposition your subwoofer. At some points in the room, its
output may be cancelled by the geometry of the room. Moving
the NX-PROSUB125/NX-PROSUB300 can eliminate this problem.
Please refer to Item 10 in the Safety Instructions for conditions
that ALWAYS require service by qualified personnel.
If you have tried all the above and still cannot get the
NX-PROSUB125/NX-PROSUB300 to operate properly, consult
your dealer or call NXG Tech Support at 1-800-733-0008.
