What would cause a popping/crackling sound in one of my stereo speakers?
Most popping or crackling sounds in an audio system come from a bad or dirty connections. Sometimes they do come from a faulty unit or component, but in most cases it is a connection issue. Whether that connection is in the connectors, wiring, circuit board or components, or even just a bad solder joint, wherever that connection is, finding it becomes the main issue to tackle. There are some relatively simple methods that can be used to locate it.First identify which part of your audio system has the issue. The fact that it is only in one of your speakers is a huge help in identifying what might be causing the noise. If both channels had the same noise, this method would not work. You can easily identify the source by swapping the channels and seeing if the noise moves or stays on the same channel.For example, swap the channels the speakers are connected to. Does it persist on the same speaker or does transfer to the other? After swapping, if it remains with the same speaker ( other channel), then it is the speaker connections (or the speaker itself) that are problematic. If it is now on the same channel (other speaker), it is somewhere in the system, before the speaker connections. You can continue to swap different components back and forth, swapping channels and work back to where the source and component is identified.Sometimes just connecting and reconnecting the cables and components solves the problem, as the connection is improved. Good luck!One component that usually becomes noisy that way (more of a crackling sound than a popping one)is a potentiometer (also called a ‘pot’, normally volume controls, bass-treble-balance controls, etc.). These can be easily identified by rotating or sliding the controls as the case may be, and listening for the noise. These can be cleaned with the right solvents or sprays.Worst case scenario is a failed or failing component such as a transistor, capacitor, resistor, solder joint (actually solder joints are relatively easily repaired, just identifying the problematic one is the challenge!), etc.Once you have identified the part or unit in the system that is causing the noise, then it will be easier to decide how best to correct the issue (replace or repair).
Catholics - If the cracker really turn into the body of christ?
Then why do you object to people taking the out of the serivice. If someone told me that it was the body of christ I would get it scientifically tested or at least show my friends
Good Websites?
so i like websites that can teach me interesting junk. how-to sites, common knowledge i may have missed, not so common knowledge, peculiar news... alot of sites i run into are really stupid and start listing lame trivia facts and stuff that just isnt all that interesting. i dont want to here about stuff that isnt useful. im looking for things that make me think--that i can apply. those of u who also spend too much time surfing the web and being frustrated with all the useless junk taking up space prob kinda get wat i mean. my interests are actually really wide, so im just looking for lots of suggestions here. tell me ur fav finds that i may not know of. thanks much!!!
The Simpsons..., who can list the...?
What a great bunch of characters, and an ever strong holding audience within their continuous funny episodes! Who can list ALL the characters, and the characters that may have played briefly? Is it possible to get them all?
What's the difference between real cheese and processed cheese?
The connoisseur knows that not all cheese is the same. Not only do they come in an assortment of varieties, but they are also made in different ways. To this end, one may ask what the differences between natural and processed cheese are. There are two primary differences between natural and processed cheeses. These differences are whey and emulsifiers. Natural cheeses have the whey pressed out of them while processed cheese does not. Processed cheese also contains emulsifiers, which help keep the fatty and non-fatty ingredients mixed together. This keeps the oils and solids from separating under a broiler or with another source of heat so it remains rich and creamy when melted. Processed cheese is also softer to chew because it has more moisture than natural cheese. In addition to whey and emulsifiers, colors may be added to processed cheese. Cheese food, cheese product, cheese spread and pasteurized processed cheese are all forms of processed cheese. Processed cheese may also contain additives and preservatives. Cheese spread and processed cheese food have more moisture and less fat than other processed cheese and natural cheese. However, they can contain ingredients the USDA forbids in processed cheese. Still, processed cheeses tend to have a longer shelf life, are less expensive, have consistent quality and flavor and melt well. On the other hand, natural cheese is offered in the same form it was when it was aged. It comes from removing water from milk with substances such as bacteria, lemon juice or vinegar. The rennet is then mixed with the curd in the coagulation process. The flavor of natural cheese actually develops as it ages. It may have been cut into chunks, shredded or sliced, but the actual form is the same. Furthermore, it is lumpier than processed cheese and separates when it melts. In the United States, the percentage of natural cheese will be reflected in the product’s name. Processed cheeses must be clearly labeled as such. Sometimes processed cheeses are preferred in certain recipes such as nachos or other treats that require melted cheese. Others prefer natural cheese to prevent ingesting the additives, preservatives and other undesirable ingredients. In either case, all kinds of cheeses can be processed or left in its natural state. Whether one wants natural or processed may depend upon a number of factors including tastes, health concerns or anything else that involves how the cheese is made.
