Question about Infinity BU-1 Speaker

Open Question

Infinity BU1 Powered Subwoofer

My BU1 powered subwoofer has a 120V 1A slow blow fuse at the point of power entry. That fuse was blown. I purchased a new fuse and when I plugged in the speaker the power light came on and immediately the fuse blew again. I don't have a schematic to know how to test the circuitry. Do you know if one is available online in a Word or PDF format?

SOURCE: HELLOOOOOO HOW CAN CONECT MY SUBWOOFER

Your problem is quite simple. The low input is for feeding a lead straight from the output of your receiver IE sub out and the high input is for connecting the sub directly to your speaker output where the alternative is not possible. Hope this helps

KLH ASW8 Powered subwoofer keeps blowing 3A-250V fuses


The transistors at the output stage of the sub amplifier circuit might be shorted so each time you power on, the circuit draws a very high amount of current which causes the fuse to blow. It's definitely a problem with the circuit so using a higher current rated fuse would probably just result in damaging the amp even more. You should ask a qualified electronics technician to take a look at it. I hope you can fix it.

No power to subwoofer


You may have a blown fuse. If it isn't located on the outside then you may have to pull the amplifier out and look on the inside of the amp itself.

Fuse blows


Both 3 or 4 amp slow blow fuses are suitable replacements for the 3.125 amp subwoofer fuse.

It could be that the subwoofer is blowing the fuse because the one you installed was not slow blow.

But, more likely is the subwoofer has a short in the power supply which is causing the fuse to blow.

Infinity Entra Sub 150 no sound or power


I had the same problem. When I opened it up, the fuse was blown, and it was a pain to find the fuse it needs (3 Amp, 250 V slow-blow fuse, 5x20 mm). Also, the 2 large electrolytics (big purple things near the amp) and one small capacitor were all blown. For 4 fuses, bought seperately from, and the 2 electrolytics and 1 capacitor, it cost about $20, plus almost 20 more in shipping, which still isnt bad considering the original price of the sub. However, the tricky part is that you have to know how to use a soldering iron to take out the old components and put in the new ones.
