what exactly is the difference between "gain" and "volume" control on an amp?
374471
Gain is the amount the amplifier increases the amplitude of the signal. Volume is how mouch the signal is attenuated at the output side of the amplifier. They really do the same thing, however it is simpler circuit wise to use an attenuating circuit on the output side of the amplifier than to use a variable gain amplifier. Most amplifiers are designed to provide a fixed gain that is only adjusted by an AGC (Automatic Gain Control) to prevent over driving the amp and the resultant "clipping" of the signal.

Analog is infinitely variable.  For example, an analog sound can have a volume between 0dB and over 130dB, which is about how loud an aircraft engine is. An analog signal can be 1dB, 2dB, 3dB...\n\nA digital signal, on the other hand, is either on or off, true or false.   The way it simulates and analog signal is by varying how long its on and off.  It pulses.  The longer the pulse stays on, the greater the value that is perceived. But digital can only simulate a signal between its on state and its off state.

in a CE amplifier, when base voltage increase, base current increases. It causes an increase in collector current also. The collector current causes a voltage drop in the collector resistor. Because the output is situated below the collector resistance (with reference to Vcc) the output voltage will decrease as voltage drop across collector resistor increase. Thus it produces a 180 phase shift. (input positive, output negative and vice versa)\n\nYou can verify with this equation: Vcc=IcRc+Vc  (Vc=Vout)\nWhen  Ic increase, Vc must decrease because Vcc is constant.\n\nYou can analyze CB and CC circuits using the same manner by writing the voltage drop equations along a line or a loop. Then find the relation between input voltage and output voltage. You will see that there is no phase shift. (Input increase, output also increase)

get an audio jack reducer at radioshack and an audio jack enlarger.  Run guitar into computers microphone and alter settings so you dont get a distoreted signal and run out of the headphone jack into amp.  I do it all the time!

This is a basic form of feed-back controller.  You create an "error" signal, based on the difference between a desired state, and a measured state.  In your example, this would be the distance the joint is from the target position.\n\nYou apply a gain to this error signal, to provide the driver signal to the actuator.  In the case of PD, two gains; one to the Difference (the error) and one to the change in the error, since the last measurement/control cycle.\n\nThe gains are not dimensionless, and in your example, assuming voltage controlled actuators, the dimensions of Gp are volts/meter.  The dimensions of Gd are volt seconds/meter.\n\nok?  For more, see the reference source below.

Just go to Start, All Programs, Accessories, Entertainment, Volume Control. In the Volume Control, the first one on the left is your actual volume control, dont confuse it with the others.

There must be a speaker sign on bottom line that is task bar. If you can not see that or removed by mistake. Open control pannel - select sound and audio devices - check on place volume on task bar. Now you will see speaker sign on task bar and you can control volume level by clicking that!\n\nExternal hard drives are good for their portability characteristic but they are comparatively slow then internal ones.

That sounds WEIRD to me!\nI guess you refer just to speaker/playback volume (and not mic/recording volume, quite a separate thing).\n\nDo you have the speaker icon always showing down in your toolbox, bottom right ?  (If not, you probably should set it to be visible).\n\nIf so - if you play a music file, are you saying that clicking that speaker icon, then raising/lowering the volume slider there, makes NO difference to the music volume ??\n\nWith a bit more specific detail I'm sure your problem can be remedied.

The op-amp is basically a differential amplifier having a large voltage gain, very high input impedance and low output impedance. The op-amp has a "inverting" or (-) input and "noninverting" or (+) input and a single output. The op-amp is usually powered by a dual polarity power supply in the range of +/- 5 volts to +/- 15 volts.\n\nOne of the most common applications of this device is the propagation of sound, like a line driver for your stereo. The signal from an external source is very low-powered ... the operational amplifier is used to boost the signal to where it can "drive" the speaker to reproduce the sound.\n\nAnywhere a signal needs to be boosted - and distortion minimized - you can find an op-amp configuration of some sort.

yep.\n\nthe volume is a rheostat (adjustable resister), so by raising the volume of the output, you are putting more energy into the cup (like shouting louder into a soup-can telephone)

Ideally your level (or gain) should be set the same as your headunits output voltage, that is if you have a 3-volt output on your low-level outputs your gain on the amplifier should be set at 3 volts as well (I know Hifonics amps use voltage markings on the gain).  Crossovers should be set at the highest frequency (if used as subwoofer amp) or the lowest frequency (if used as voice-grade and above) your speakers allow.  If your subs can only go up to 100Hz before distortion, then stop at 100Hz.

Need more information. Why are you people bellow suggesting you can just increase current?, you cannot if your load (resistance/impeadance) and voltage remain the same. Current is the result, Voltage and resistance are the only two forces that can be manipulated directly. Just because you read something, doesn't mean it can be applied in the real world.

I think you're referring to an amplifer control footswitch. Some amps have a jack for these others don't.

depends on what gain you're talking about, monetary gain, or power output of an amplifier....gain is the increase in power output in an audio set-up, to boost the gain, an amp is used to ramp the power up to a usable level, that way when you speak into the mic, or strum the guitar, you get a more powerful audio signal...basically saying...making the audio louder by increasing the amplitude of the signal

You'll most likely have to use a Burner Software which has audio volume leveling as an option.  Most of the new commercial software (NERO, ITUNES, etc...) has the option somewhere in the menuing system.

while holding the guitar, walk over and face the amp. turn it on realy loud. instant feedback

Pulling it tighter will decrease the amplitude. Allowing slack will increase amplitude. Increase the input frequency
