You should power the system off right away when you hear that because the thermo shut down does not kick in. The temperature will eventually damage your semiconductors and capacitors and the system will be completely damaged. You need to ventilate the system better and even upgrade the heat material if you can.
i have a similar problem: my problem is that my sub doesn't power on when i put sound on my amplifier, then i have to power on manually the sub, but how it doesn't detects sound, it comes power off after 15 min.
Open it up and see what is in there! You might find a fuse blown. It might have just blown, without a fault, if you are lucky. If not check out the part numbers on the amp board. All semiconductors numbers, then put the numbers into google. You will soon find out if they are obtainable!
I HAVE 4 PS212 AND FROM WHAT YOU ARE DISCRIBING SOUNDS SIMILIAR TO WHAT HAPPENED TO ME. PLAYING THE SUB AT FULL VOLUME AND CLIPPING OCCURED NOT KNOWING THAT THE FAINT SMELL WAS THE VOICE COIL BURNING AND CONTINUING TO PLAY UNTIL KNOW SOUND LESSON LEARNED BUY A BIGGER SUB SYSTEM OR REPLACE YOUR SUB WOOFER.
IN MY OPPINION THIS IS A VERY GOOD PRODUCT WHICH I HAVE BEEN ABUSEING FOR MONTHS . SO QUIT WHINEING AND PAY YOUR DUES.
Try hooking up a different signal input to your powered sub, another
stereo or even a dvd players audio output to the sub will work for a
test. Just make sure the subs gain is down before starting. If it
still not producing sound, the subwoofers amplifier is bad. I hope this
Hello, Unfortunately your subwoofers amplifier circuitry will need to be repaired ,the amplifier is bad and kicking in to protect mode. This mode is designed for safety of the unit and user and sub should not be operated until repaired as it may incur more damage to the components. I hope this
