Question about Audio Players & Recorders

Open Question

First off all Hello to everyone, The current situation is a technical problem based around the Behringer B125A speaker when the power lead is plugged in and turned on the speaker only comes on for precisely 2 seconds and discontinues also a perfect example would be the back of the speaker featuring the clip light comes on for 2 seconds and then it dies off along with the speaker which indicates that the power goes off.In regards to this matter i have checked the fuse and replaced it with another and the same problem occurs and i believe there is a solution to this problem. regards Michael Tylor

SOURCE: Crossed speaker wires...did I destroy my amp?

Most likely what you did was burn out the output transistors to the center channel. and probably the Bias resistors that control them. The parts themselves would be inexpensive. But they would probably have to come straight from Onkyo. And you would have to know there part number. And to get matched complimentaries. Mark up. And how far into the circuit the damage went. If I was to repair it I would probably put $100 to $125. But depending on the age of the unit and what a new won would cost is what I would use to decide to replace or restore.

It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck

Hello,
I got the same problem and on my AVR1404 it is the regulator
-15v (7915). You can control voltage on
R145 : +15v and
R146 : -15v.
The other side of these two resistances are joined together.
Good repair....

SOURCE: Kenwood Receiver KR-a5020 receiver won't come out of standby

The unit is in what is commonly known as "protect" mode. This means that a problem has been detected in the final output stage of the amp and the outputs are shutdown to prevent further damage to either the receiver or speakers. This should not be a difficult repair for a service shop. Expect a parts cost in the $25-$40 range. Add in the local labor rate for the total repair cost.

SOURCE: Technics SA-DX950 intermitently sounds blown out

There are poor solder connections at the output amp pacs and the voltage regulators. Once these are resoldered the problem should go away. If you can solder, resolder any connections that appear grainy or have rings. If you can not, this should be effectively a labor only repair for any shop that works on audio gear.

I have had a Kenwood VR-407 reciever for almost 9 years now but it has just started cutting off. The small power/standby light above the power button goes off when I power it up but then it shortly...


If you've already disconnected the speakers then I suspect the fault is internal on the amplifier and the unit is shutting down to protect iteself.

The fault with most amplfiers can normally be traced to blown or leading capacitors (bulge on the top or liquid around base) which can be replaced for little cost if you've got the technical ability and equipment to desolder and resolder components on a PCB.

First thing to do would be to remove the cover and check the capacitors as detailed above.

Do you mean "Behringer" PMP2000?

If so, register and download the manual for free at retrevo.com

http://www.retrevo.com/support/Behringer-PMP2000-manual/id/23281ag523/t/2/

As always, you should refer to the manual FIRST before coming here.That is where WE will usually start. But this one offers NO troubleshooting guidance or you could be talking about a whole different product so...

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.

Hey, I have a pair of CPL46 speakers, im looking at getting a behringer PMP6000 powered mixer to run them, just checking if this is a good idea, thanks


You can find the spec sheet for the speakers here. The Behringer is rated 600 watts RMS at 4 ohms, right at the high end of the recommended level for the speakers. So it looks like a good match.

Behringer Truth B2031A powered monitor speaker - radio interference in left speaker


A well know problem to the Behringer Truth B2031A speakers is radio interference and noise. I had the same problem with mine and found a solution on a forum!

If you open the speakers, you'll see a cable from the main board that runs to the 2 lights at the front (on/limit LED's). It functions as an antenna... Disconnect it and your speakers are silent, finally. (OK no leds, but I can live with that).

Better sound through bose speakers?


If you have the money to plunk down for a Bose Acoustimass home theater speaker system, I'm sure you will be quite pleased. Of course, as you indicated, appropriate placement of the speakers is important. Still, I'm sure you will find that a properly placed Bose Acoustimass speaker system will fill your room with high quality sound, substantially better than Onkyo's stock speakers placed equally well.

I own a Technics home theater system, which I initially purchased to use in my family room. Yet, when I listened to a Bose Lifestyle system (powered by Bose Acoustimass speakers), I could have nothing less. The Bose system went in the family room, where everyone could enjoy it. I put the Technics system in the bedroom, where it is rarely used.

Yamaha RX-V596 Receive turns off after pressing Power


Sometimes the receivers turn off if the speakers are shorted in order to protect the AMP circuit. So try this - 1. Disconnect all cables (speakers), inputs from Tape Deck, VCR and other input devices), sub-woofers, rear speakers all. Except the AC power cord. Then turn it ON and see if it stays on. If it still has the same problem, then most probably your power circuit inside the receiver has a problem - like a shorted Capacitor or diode etc. Based on how technical you can be and what resources and time you want to spend, this is repairable. But based on the price of a receivers these days, it is not worth. Good Luck!
