MP3 Players Audio and Sound Systems

MP3 Players, audio and sound systems are relatively new. They are more compact than the earlier CD players, and are not prone to skipping. These devices can also store more songs than previous gadgets.

What happens if a capacitor in an audio amplifier becomes open circuit and how does this affect the output?

Without knowing the location of the capacitor in the amplifier (which you do not give) no specific answer can be given, only possibilities assuming various locations (e.g. input coupling, power bypass, bias networks, interstage coupling, virtual grounding of shields). Each will have one or more characteristic symptoms it could produce in the output.

Can you convert SNG files to WAV files?

No, but you can open them using apple quick time player.

By the way, I am just a child of 11 years and even I know that!

What would cause a loud humming sound to come from surround sound speakers when connected to a computer?

Could be that your speakers are too close together or if you are using a boom mic or other mic it may be too close to a speaker. A power transformer/converter could cause that too if it is too close to a speaker. This humming is a ground loop. To get rid of this there are a few options. If the computer is plugged into the surround sound through a stereo mini to two rca cable you might try replacing the cable. Another option is to go over to your local radio shack and pick up an RCA ground loop eliminator. RCA is not the name brand but the cable type. It is about $15 and it looks like a D battery wrapped in black plastic with two rca cables coming out of either end. You will also need some couplers to attach the stereo mini to rca adapter to the ground loop eliminator. It is expensive but it will work. If it does not eliminate your hum radio shack will take them back with the packaging and reciept. (also if it doesn't work one way try flipping the ground loop eliminator around the other way.)

Can you hook two amps together and get one combined power?

If you mean in series (the output of amplifier a plugs into the input of amplifier b), probably not. Unless amp b can handle the input power delivered by amp a, and then linearly amplify that signal up to its own level, you will get massive distortion. If you've ever heard an electric guitar in maximum overdrive mode, you have a sense of what will happen.

The way to do this is give each amp 1 speaker and y-cord the INPUT of each amp.

756.302 MB is how many GB?

There is 1000 MB in every GB so that would be 0.756302 GB

No that is wrong there are 1024Mb in 1 GB (stupid manufacturers of HDD's rate them at 1000mb, so you never actually get what they say their HDD capacity is. e.g. My HDD is rated at 640 Gb but it is only really 598Gb. When you buy Ram you get what you pay for e.g. 512mb is 512mb of ram) I hope that clears that up for you. Its false advertising at it's most obvious.

Does zune cost money?

If you want to get the Zune Pass, the cost is $15 a month.

How much is 64 gb?

A GB refers to storage space on a disk drive. 100 GB could hold an entire library floor of academic journals. 100 kilobytes would be one page of a book. 64 GB is equal to 65,536 kilobytes.

Can you put 2 8 ohm's speakers in 1 channel?

Your simplest scheme would be to wire them in series - one after the other - thus presenting a 16 ohm load to the amplifier. This will cause no harm to the amplifier.

If you wired them in parallel, then the effective load would be only 4 ohms, and this would cause more load on the amplifier. Depending upon the design of your amplifier, this could cause more distortion.

In closing, it is only in the 'mid range' that the impedance of the speaker is the nominal load - say 8 ohm. At 'resonance' - generally at frequencies of a few tens of Hertz, the impedance of your speaker will be a few times its nominal impedance. At high frequencies, again the impedance of the speaker will increase to a few times nominal.

What type of materials are used in earphones?

It says "An in-ear type earphone according to the present invention includes an in-ear type speaker element and a cable disposed externally of the earphone. The cable is coupled at one end to the speaker element such that the cable hangs freely from the speaker element. The opposite end of the cable is coupled to a plug. The plug operatively connects the earphone to a sound signal source. A sliding round shaft is rotatably mounted at one end of the speaker element. A sliding sleeve receives an opposite end of the sliding round shaft and allows it to move along a longitudinal axis. The earphone also has an ear hanger with a helix stopper end, a curved hook section, and a lobule stopper end integrally formed and contoured to the general shape of a human ear. The helix stopper end is mounted to the sliding sleeve in a fixed manner."

Is a mpeg audio file the same as mp3?

Not necessarily. Although the most common MPEG audio format, there are also other standards, both previous to and successive to MP3. MPEG Audio Layer 1 (MP1) and MPEG Audio Layer 2 (MP2), as well MPEG-4 Part 3 could be classified as an "MPEG audio file."
