Good signals to the amp,
check the bad side with a known good speaker first.If it still doesn't work most likely burned out that side. Usually a power IC chip depending on model.
Speaker output knobs producing crackling
The problem is that the potentiometer that the knob is connected to is dirty. This is a common problem with age, or quality of installed potentiometer. (potentiometer is the name of the component that the knob attaches to. It usually looks like a 1/2" long cylinder)
There are multiple solutions to this problem. The first is free & anyone can do. While the unit is off. Twist the knob back and forth quickly and rapidly numerous times. Roughly 10-15 times will do. This sometimes allows for the connections within the potentiometer to reconnect, and remove the crackle.
The second solution involves some handy work. The unit's case will have to be disassembled, and the potentiometer that the knob is attached to must be found. There is usually a relief hole somewhere on the housing. Within this relief hole one can spray contact cleaner. This cleans the contact within the potentiometer which is the cause of the crackle. Once the pot has been sprayed, rotate the knob like in step 1.
If steps 1 & 2 do not work, the potentiometer will need to be replaced. This work usually needs a professional. If you are handy with a soldering iron, it can be accomplished. Look for any particular part #'s on the crackly potentiometer, and then copy these into a online parts catalog. Mouser.com and Digikey.com are excellent resources for finding parts. Upon finding a replacement, it can be swapped out, and provide the user with a crackle free knob.
As always, make sure power to the unit is disconnected. If you are unsure of electronics, please use caution, as dangerous voltages may reside that can cause personal injury.
Amcon[crown] dc300a amp has loud
Question...does the problem occur when the power amp is on only by itself ( no pre amp power ).
If it does, then because of the age of the amplifier, it could be either a capacitor, or a transistor has died. Capacitors and transistors both have age issues. Since that is a nice amplifier, I would suggest taking it to a shop because there are MANY things that can cause this condition. Subsequently, because of the age, if one component has failed, there are sure to be more to come. If you wish to keep the amp, you should consider getting it rebuilt. Hope this helps... Rob

The main board in the crown macro tech 2400 is
Do you know for a fact that you do not have a working board? If there's a problem with anything from speaker mismatch to loose transits, the board will not operate. This receiver is made of discrete components so, it couldn't be that hard to fix or maintain. But if you want a new or used one, they have them on ebay though there a little pricey.
I have a Crown Power Base 1 AMP, with a buzz. It
Buzz through speakers usually means it is picking up humm from a power source. Check your mixer and amp input (gain) levels. If one is turned up really high you will get buzz. If that doesn't work check where it is plugged in. Is it sharing power with another electronic piece of equipment? You can also buy a power conditioner (I believe it is called). It will put out "clean" power (power without Hz humm). They can be expensive though. Less exspensive mixers will put out humm. Lower that gain as low as possible and raise the amp gain. Or vice verse
How do I change to degree mode on my porpo YH-2000
- Power Off: Turn off the device.
- Jumper Configuration: Locate the jumper labeled "S16" on the device. Initially, it should be connected to pins 2 and 3.
- Power On (Alarm+All LEDs Flashing): Turn the device back on. You'll see the alarm LED and all other LEDs flashing.
- Power Off Again: Turn off the device once more.
- Jumper Adjustment: Change the jumper configuration from pins 2 and 3 to pins 1 and 2.
- Finished: Your Porpo YH-2000 is now set to the desired angular unit mode.
If you encounter any issues, you can press the reset switch on the back of the device to reinitialize it.
Openfit Shokz battery replacement?
Question edited for clarity, typo and CAPS.
Question moved from Cars and Trucks category.
Claim on the warranty irrespective of how long you have had them. They charge $180 but they cost them $20 to buy from China. Package them up and send them tracked and ask them to replace the batteries.
