Crown xls 1500 power amp
That is a subjective statement. You need to measure the SPL at the speaker and check against the specs and also measure the power from the amp to have the data to check and compare with. That will give you an objective answer. You could have lost part of your hearing, I do not know!

No sounds both channel
Power output amplifier circuit should be checked. If there is any delay relay fitted, its drive circuit too should check. Check all the components at the main power amp output section. Refer its schematic diagram for more details. If you wish to get some details; check the site linked here. Viewing it in "

Why my fan does'nt spinn
HelloCheck the voltage comes to the fan first. If voltage is there and fan does not spins, either the fan is strucked by some external substances like dust or so. Check whether it can be turned freely by hand. If there is no fiction found in tuning the fan, replace it. It is faulty. If it is dusty, clean it. OK.

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

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
