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.

Don't think you can format CD-R's - they are manufactured and formatted ready to use. CD-RW's however can be formated, and/or re-formatted.

How many parts are in an iPod?
The key components of the iPod are the casing, screen, mainboard, battery and click wheel. The iPod also requires a cable and iTunes software to connect it to a computer. iPods also come with headphones and in some cases a dock and a protective case. The total number of parts in an IPOD is between 400 and 500.
Is there a default combination set for the lock on the iPod nano?
yes, the "default" code if it asks you to enter your "old code" (and you haven't yet set a code) is simply 0000
What are the Top ten sound recording programs?
The top ten sound recording programs include GoldWave, Mixcraft, Wavepad, AV Music Morpher, Blaze Media Pro, i-Sound Recorder, RipEditBurn, Easy Hi-Q Recorder, Audio Recorder Platinum and RecordPad. There are also other programs that are good apart from these ones. You can opt to choose one that meets your needs.
1770/1024 = 1.728515625
There are 1024 mb in a gb, therefore 1/1024 is one mb in terms of gb, multiply by 1770, and you get
1770/1024
What happens when you bridge an amp?
If you bridge a 2 channel 4 channel ect. you are taking the power from both channels as if it was a single channel amp.
12.8 megabytes is 1 1/4% of a Gigabyte, so technically, there aren't any gigabytes in 12.8 megabytes.
You probably need to charge it 'cause it's out of batteries. Or something's just plain wrong with it. But I would guess that it's because you need to charge it.
Can I connect two 4 ohm speakers and a 8 ohm speaker?
I depends on "how" you are connecting them. If you connected the 4 ohm speakers in series (positive terminal of one to the negative terminal of the other). This will leave a negative terminal of one unconnected and a positive terminal of the other unconnected. then connect them in parallel (the unconnected positive terminal of the 4 ohm speakers to the positive terminal of the 8 ohm speaker and the unconnected negative terminal of the other 4 ohm speaker to the negative terminal of the 8 ohm speaker. This will produce an overall 4 ohm load for 1 channel (assuming you are connecting to a stereo)
Or if you are connecting to a stereo with two 8 ohm outputs. Connect the 8 ohm to one channel then connect the above mentioned series connected 4 ohm speakers to the other channel for a total load of 8 ohms on both channels.
Parallel connections will equal less than the individual speaker load. The formula for this is: R X R/R + R where R is ohms for each speaker ie. Two 8 ohm speakers in parallel would be 8 x 8 (64)/ 8 + 8 (16) which is 4 ohms.
Series connections you just add them together ie. Two 8 ohm speakers in series would be 8 + 8 or 16 ohms.
FYI. If you measure the speakers with an ohmmeter it will be less than what it says on the speakers.
Speakers are measured in "impedance" which takes into account "reactance". The resistance of the speaker coil will change slightly with different frequencies applied so an 8 ohm speaker may read as 5-7 ohms (more or less) with an ohmmeter. A 4 ohm may read as low as 2.5 ohms on the same meter.
Some output transformers can handle half the ohms but it is always safer, as a general rule, to go "up" in speaker impedance without any damage. It's not wise to vary any with a system with solid state (transistor or IC) output coupling.
Hope I didn't get too technical. There is lots of good info on the internet about speaker configurations.
Yes, they do. You need small electromagnets in the speakers so that you can hear the radio station.
The incoming radio signal is converted to an electric current by the aerial, boosted by circuit boards in the radio, then transmitted by the speakers by using the current to vibrate the electromagnets.
Can you add an auxiliary input to a portable radio?
I was wondering the same thing. Does anyone know if changing your am/fm/cd selector switch to a 4 position switch (the 4th being aux. input) would work?
Yes you can add auxiliary audio input to any stereo but you will need to solder a 5 pin aux 3.5 jack into the radio board before the radio preamp after the FM output, there are 2 cables for audio in 2 cables for audio out and 1 for ground,
when you insert the headphone style jack the 5 pin aux jack will stop the audio from the FM and play the audio from the external source
