An amplifier usually has 4 channels. A, B, C, and D. A and B are used for effects in clean. C and D are used for sounds and effect changes in dirty.

Why you need operational transconductance amplifier?
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
What is a 2 channel amplifier?
A 2 channel aplifier is an amplifier that can operate two channels. It is basically two 1-channel amplifiers in a single box. This unit is usually intended for operating a left speaker and a right speaker. A channel is the signal/power combination intended for one specific speaker. A 'Stereo' audio system typically has a left channel and a right channel. More advanced audio systems may have separate channels for different types of speakers (midrange, woofer, tweeter, very commonly subwoofer, sometimes supertweeter) or for rear channels (surround.) This sort of setup was modern during the early 90s. A bridged 2 channel amplifier is constructed in such a way that the amplifiers can be set up to operate inline providing the effect of a more powerful one-channel amplifier. If durability is a concern, a bridgeable two channel amplifier used for two channels tends to work well because it's likely to have higher quality or just more diodes so as not to be destroyed too quickly during bridged operation. Using a more powerful amplifier with the gain turned down is also a good idea if longevity is a concern.
What are Pre-Amp outputs?
They are RCA type connectors on the back of your Head Unit (Radio). There are 2 connections, usually blue and white, the cord for this has the same connectors on both ends. The Pre-Amp outputs are a direct line for the Signal from your Head Unit to go directly to an Amplifier (you will see similar connections on your Amplifier as you see on the back of your Head Unit), so when you run speaker wire from your Amplifier, the speakers will play the sound (Music) your Head Unit is producing no matter if its from the CD or FM/AM tuner or AUX input like from an I-Pod.Another AnswerA pre-amplifier, which is also known as a 'control unit', a high-fidelity unit which is separate from, but which must be used together with, a 'power amplifier'.Pre-amplifier/power amplifier units are normally regarded as 'high end' equipment and tend to be very expensive. The pre-amplifier unit is equipped with inputs for phono, CD-player, tuner, and various other auxiliary units and (usually) provides a single pair (right- and left-channels) audio outputs for connection to the power amplifier. The pre-amplifier is the unit which provides the volume control, tone controls, filters, etc., while the power amplifier simply amplifies the output from the pre-amplifier unit. The output usually takes the form of a pair of RCA connectors, usually colour coded white and red.Some 'home theatre' amplifiers provide a 'pre-amplifier' output, which bypasses its internal power amplifier, for the purpose of adding external power amplifiers, if desired.
Why mostly a transister is used as amplifier than diode?
A diode is not an amplifier. It is a rectifier with asymmetrical voltage breakdown voltages. Usually the forward voltage is around 0.6V to 0.7V (silicon), and the reverse voltage is smaller than breakdown voltage, which is much higher. A transistor can be used as an amplifier, by taking into account the fact that the voltage breakdown curves vary, usually collector-emitter, as a function of some other current, usually base-emitter, but this depends on the class of the amplifier and whether or not the transistor is driven into saturation.
How do you filter rf signals that distort television reception from a rooftop antenna?
There are a number of steps that you can take to prevent this distortion from occuring. But in order for you to know what to do, you should specify a few things, first: a) Do you have an antenna signal amplifier? b) Is it just one or two channels being affected, or is it all of your channels being affected? c) What channels and ranges does your antenna receive? d) What sort of distortion is it? Are adjacent channels bleeding into this one? Are there horizontal streaks and lines appearing? Or is it just an entire screen filled with noise? If all of your channels are affected or wiped out and you have an antenna signal amplifier, it may be that your amplifier's transmitted signal is too strong. Also, it could be interference from an adjacent channel or the FM band. In this case, you may need a bandpass or a bandstop filter. To get a bandpass or bandstop filter, you should probably turn to an electronics provider like Tin Lee Electronics (www.tinlee.com). You can also contact them about your problem and they should be able to help you solve it. In any case, if you could specify the above information, it would be much easier to find an answer to your problem.
4 channel amplifier?
This is an amplifier that has 4 sperate channels and can be wired in various ways. Usually you would have 1 channel per speaker so you could do 4 speakers with this. However, sometimes it is possible to join the channels together and get more power out of fewer channels - you can get anything from 2-4 channels out of a 4 channel amp.
Can I connect two 2 ohm speakers to the front channels of my amp and then connect 2 4 ohm speakers to the rear channels of my 4 channel amp?
This depends on your amplifier's specifications. i would recommend looking in the amplifier's service manual to avoid disapointment or damage to your amplifier or speakers.
Can you plug in 2 instrument to an amplifier with 2 channels?
Unless the amplifier has two inputs, you cannot plug more than one instrument in. The two channels are used off of the input to change sound between clean and different distortion types, not for another instrument
What is a power amplifier?
A stereo power amplifier is simply a two channel power amplifier. You can runn it in a couple of ways; Stereo, mono or bridged. Stereo has a seperate left and right signal in and sepetate out. Mono is one channel in and both output channels reproducing the one signal in. Bbridged gives you the same as mono BUT it uses both channels as one output.

What is the advantage of a bidirectional cable amplifier over a unidirectional cable amplifier?
A biderectional cable amplifier with a bypass is excellent for use with digital TV, because it amplifies the return signal. Using a unidirectional cable amplifier can result in some channels that do not work because the return signal is not amplified.
What happens when you bridge an amplifier?
It combines two channels into one channel making the output for the speakers/sub woofers more powerful. But it is only good to bridge an amplifier if you know the amp is good quality because if its not, it will mess up the amplifier soon.
Why are inductors not usually connected to an operational amplifier?

Why base in grounded in common emitter transistor as amplifier?
With a common emitter amplifier it's the emitter that is usually grounded.
