How does a stereo power amplifier work?
Quite well. But what kind of amp? In general, the amp takes a "line level" signal (left and right channel) and puts it through a series of amplifiers to make the signal bigger (amplify it). This is an increase in what is called the "gain" of a given stage or of a series of stages. Small signals drive the "control" circuit of the semiconductor devices, which are the amplifiers themselves, and this causes large swings in the output voltage of the stage (giving the amp gain). After a few of these, the signal is sufficiently amplified and can be used to drive a pair of speakers.
How many speakers can go into a single stereo system?
All amplifiers are rated to handle a certain speaker impedance. The majority of loudspeakers have an impedance of 8 ohms while most amplifiers will be able to drive a minimum load of 4 ohms. It is important to check the ratings of the amplifier before adding more speakers. If two 8 ohm speakers are wired in parallel, the total impedance will be 4 ohms. If 3 speakers are wired in parallel then the total impedance will reduce to around 2.5 ohms. If the total speaker impedance is lower than the rated impedance of the amplifier, it is quite possible to damage the amplifier as the output level is increased. To be safe, make sure you understand the impedances of the speakers and the amplifier's rating before hooking anything up.
How do you select speakers with respect to the impedance of the amplifier?
Amplifiers are rated to operate within a range of impedances. Typically, a domestic amplifier will drive a minimum impedance of 8 Ohms or 4 Ohms. Using speakers that have an impedance lower than the amplifier rating is likely to increase distortion and can damage the outputs of the amplifier if the levels are too high. Using speakers that are significantly higher than the minimum rating will not cause damage to either the amplifier or speakers but it will reduce the power that is delivered to the speakers. In most domestic systems, this limitation of the power output is not likely to be an issue. Any amplifier rated to drive into 4 Ohms will work well with speakers of between 4 and 8 Ohms. An amplifier with an 8 Ohm rating should be used only with speakers of 8 Ohms or higher.
Can an 8 ohm amp drive 16 ohm speakers?
Never heard of a 16 ohm hifi aplifier. All amplifiers have an output impedance of less than 0.1 ohm. We use always impedance matching with a low source impedance to the much higher load impedance. Scroll down to related links and read "Amplifier, Loudspeaker, and Ohms".
What is Kenwood sigma drive?
Almost all amplifiers use "negative feedback" to reduce distortion in the power stage. Sigma Drive uses an extra set of wires to include the speakers in the feedback loop so that the amplifier can use power reserves to ensure the speaker track the signal. Quite effective on bookshelf speaker, up until they reach there maximum power level. Less impressive on really good speakers but at least it seemed to be transparent if it wasn't helping.

Are the speakers in the thunderbird 3 way?
the speakers in the thunderbird are standard paper cone speakers. They are not 3-way though the stock amp in my 95 had plenty enough to drive 4 4-way speakers that i put in it.
What is the purpose of tube amplifiers?
An audio amplifier boosts sound levels. Audio amplifiers typically contain transistors, though the transistors are often packaged inside ICs (Integrated Circuits). A transistor is an electrical device that allows a small amount of voltage or current to trigger a larger level of voltage and/or current. So an amplifier reproduces the sound at a higher amplitude or strength. Of course, there are some tube-type amplifiers that are still in existence. Those are rare and it is hard to find the tubes. Vacuum tubes were what was in use before transistors. There are different types of audio amplifiers. Radios and televisions contain audio amplifiers to be able to drive the speakers. Once the audio signal is extracted from the radio waves and passes out of the detector stage, it is too weak to drive a speaker. Sound boards in computers are capable of driving headphones directly, though not always at a comfortable volume. If you want the volume to be louder, or you want to listen through speakers, you would do best to get a set of amplified speakers. They contain an amplifier inside, and that is why they require batteries or a power cord.
Can you connect a pair of speakers to your computer?
In general, you cannot connect a pair of speakers to a computer, because the computer's sound board does not normally include a power amplifier fit to drive a speaker.It might be possible to drive very small speakers with a high impedance directly from a sound board's headphone output, though.Note that most "PC Speakers" can be directly connected to a computer's audio output because the speaker itself contains a power amplifier. Strictly speaking, such a speaker is a combination of a loudspeaker and an amplifier (sometimes also called an active speaker).
Can you splice an AV cable to speaker wire to plug in speakers?
Maybe. If you need to drive passive speakers, you will need an amplifier. If you have powered speakers, you might not be able to control the volume of the signal.
How many 30watt speakers can a 240watt amplifier drive?
Depends on the amp and type of speakers brand and ratings would be nice info u also need to look at ohms of the amp and the speakers
What are some methods of output for a computer?
Monitor, Printer, Speakers, CD Drive
