First of all the KEF is a powered sub which means that it wants a line level signal NOT a speaker level. Send the signal from a tape output or pre-amp output to the sub input. The overload is because the impedence load for the speaker output is too low and looks like a short to the amp. Continued attempts to connect the system as described will result in damage to the output section of the amp.

Please let me know if you need more info.

How can you bypass a subwoofer amp


If it came actively powered and permanently connected but you do not want to use the supplied amplifier, then you need to disassemble the subwoofer cabinet and disconnect the amplifier from the driver.

Im having trouble with connections from kef psw 1000 sub to onkyo tx sr506 amp. sub is making a bit of a humming noise but not getting any proper sound through. dont know what im doing wrong. can anyone...


Have you got the sub defined to the Onkyo correctly? Try conencting the sub's input to one of the Tape Out connectors and play some FM through it. That will prove if the sub is alive. The nwe can troubleshoot the correct failing device.

On switching my technics sa-dx750 it says switching off overload


The question is what is causing the overload? The power supply or the output devices on the heat sink?
If you have accidently shorted a speaker wire, then the answer will be output devices, otherwise it could be anything in the power section. You may find a burnt or damged device with either of the causes.

Overload on sagx550 technics


Disconnect all speakers at the receiver then turn it back on. If it still goes into "overload" you need to have the unit serviced. If it stays on, post a comment and I can walk you thru troubleshooting your system.

Loud buzzing from Kef PSW1000 Subwoofer


yes. A good idea. Kill power to the sub, then unplug and remove everything from the sub. go ahead and plug it in again and check for buzzzz.
That is test one. if you have buzz still, its the sub assembly. bad luck, but not impossible. If the buzz is gone its one of the signals to the sub. They can produce a buzzz without any signal coming from your stereo equipment. Replace the feed line, enjoy! BTW...Kef sure does sound clean. good choice.

Technics SA-DA10 jumps into overload after 10 minutes


Have you tried connecting speakers? What was the result?

Yes, when you turn the volume up on these amps (or when the output gets past a certain level) the cooling fan should automatically come on.

Weird burbling muffled squeak noise!


you can simply and easily replace 3 capacitors on the main amplifier board (c58 - 47uF 63v or 100v) + (c52 & c53 - 220uF 25v) but stand them away from the board on the length of the capacitor leads to prevent them from absorbing heat from surrounding hot components (with heat shrink tubing to prevent shorting)

these are usually the cause of most problems with KEF PSW subs, as for it sounding wooly, this is just the way it is, mine is the same.
