The amplifier that drives the built in subwoofer has stopped working. The first thing to do is check that the power cord is plugged in to a live power outlet. Next, replace the fuse which you'll find on the large black metal plate on the back of the speaker. Use only the size and type fuse specified. If that does not work contact Definitive customer service at (800) 228-7148.
this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....
Well, I have the same problem and I would think it has something to do with the RCA-connections. If I power up my head unit while I have my main fuse for the amp's removed and then replace the fuse as the head unit is already playing music (thus putting out a current through the RCA-connections) it works just fine. But if I just power up my stereo with the fuse in, my subs go all crazy. I guess it has something to do with disruptions in the rca cable. Maybe they are drawn too close to some power cables or speaker cables?
A few more questions-
Does the sub hum without anything plugged into it except for power? If it makes a real loud hum almost a squeal then I think the rca cable between the receiver and the sub is dead shorted and needs to be replaced. If it's more of a low level hum, then it's a ground hum caused by many things, ie........the receiver and the sub being on different power circuits in the house.......sometimes diconnecting the cable tv feed as it enters the room while the sub is connected and humming to see if it stops........the easy fix sometimes is using a 3 to 2 prong ac adapter but lifting the ground on such a powerful amp could be a fire hazard.
You didn't say is your sub active or passive.If its active first check signal cables from theater system,power line of the sub, it has to be the same phase as the system.If its passive take a voltmeter disconnect the sub from the system and measure for DC voltage on the SUB output on the system when its OFF.If DC voltage is present your amp is damaged.It can also be that the preamp circuit for the sub doesn't mute the input when unit is on stand by and you hear frequency of your power supply (50-60Hz) on the sub
UNPLUG THE GREEN WIRE FROM THE COMPUTER AND PLUG IT INTO A CD PLAYER IF IT WORKS BETTER ON A CD PLAYER THAN THE COMPUTER IT SELF THERE MAYBE A PROBLEM WITH THE SOUND CARD AND ALSO TRY THESE STEPS I AM GOING TO GIVE YOU I AM SURE ONE OF THEM WILL WORK.
1. Please ensure that the all the connections between the satellite speakers and the subwoofer are firmly connected. 2. Next, please connect the green colored 3.5mm audio jack to another audio device such as an iPod or an MP3 player. 3. Ensure that the SoundTouch
remote control is firmly connected to the back of the subwoofer. 4.
Connect the power cord from the subwoofer and connect it to another
single power outlet in your house. If you have an automated voltage
regulator (AVR), please connect the power cord through the AVR instead
of connecting it directly to a power outlet in your house. 5. Power up the speaker system and check whether the power button on the SoundTouch remote control will light up. 6.
Turn on the Matrix Mode ON. This option is on the SoundTouch remote
control. This is to ensure all speakers from the speaker system will
produce audio that will be played from the audio device. 7. Play audio from the audio device. Check and see whether the all the speakers will produce audio being played from the audio
