Question about JBL PB10 Subwoofer
I have a JBL PB10 subwoofer, and when it comes on, it makes a loud burp noise, and then it's fine after that. If I connect it to the subwoofer output on my receiver it burps frequently. When I run it from the main speaker outputs and attach my JBL L-100s directly to the subwoofer, it only burps once when I turn the receiver on- not as bad. What would cause that, and can I get rid of it?
In the industry - It is called "Turn-On Thump".
There are some manufacturers that eliminate components like noise filters on enry level lines to save money.
There is no way to lessen this noise without ripping the amplifier apart and having a technical knowledge of the way amplifiers work. It would involve hard-wiring a slow charge capacitor in the turn on line so it gradually builds power instead of getting it all at once.
Thanks for using FixYa - a FixYa rating is appreciated!!
