SOURCE: My Polk PSW 303 subwoofer emits a hum when plugged

Hiya sounds alot like there is a power supply issue with the unit that will require repair for it to be doing off or on. Probably wont be to expensive, request a quote first to make sure viable.

Best of luck

The power supply or amplifier has a shorted component.

SOURCE: Optimum set up for Polk Audio PSW 10?

Run 2 RCA cables from the two Purple connections on your Receiver (Labled "PRE OUT SUBWOOFER") to the Red and White connectors on the back of your Sub (it does not matter which Purple connecter you plug into either the Red and White)

Set the volume control on the Sub to about 75%, and keep the power switch in the "ON AUTO" position. To set the Low Pass value, look at the back of one of the front speakers in your setup, and note its frequency range (will look something like 100Hz - 17kHz). Set the Low Pass at a value slightly higher than the low value on the back of your surround speakers.

To set the phase switch, stand in the middle of the room with some music on (something with some bass, but not over the top bass) and have someone switch between 0 Deg and 180 Deg. Listen for which setting sounds "Louder and Fuller". This is the one you want. You will need to do this each time you move the Sub, as its position may change its phase in relation to the rest of your system.

Good Luck!

Polk Audio PSW202 subwoofer. Replaced burnt fuse but blows the next fuse after connecting to amplifier and powering on. What else can I do?


Fuse probably went bad because either the large filer capacitors at the edge of the PCB went bad and or the final output IC mounted on the heatsink(15 pin) fried. Check the capacitors and all the semiconductor components on the board for burn marks or corrosion. You have to remove the heat sink clamp from in front of the output IC to adequately visualize its condition. In fact you might have to remove the large aluminum heatsink attached to the chassis to get a good view of the IC. If it or the heat sink clamp show signs of thermal burns you need to replace it. The IC is a TS TDA7294 mono audio amp available at Mouser Electronics. Replace the 35V 4700mF caps with 50V 4700mF caps. You will only have enough space on the top of the PCB for one of the larger caps. I mounted the other on the circuit side of the board. Note the polarity of the original caps and respect it in their replacements. The fuse is a 5 X 20 medium speed slow blow 250V 2.0A glass fuse.
