It doesn't. You can make a differential amplifier with a single power supply.

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 .
Can anyone suggest how can you choose amplifier and speakers?
you need to choose speakers according to the power supply of amplifier, so that the amplifier can wrok. Besides, to create good sound effect, you need to take your room area into consideration, if the room is small, amplifier and speakers with high power is not necessary. You can visit website of Unify company, they have many packages for amplifier and speakers, hope it can help somehow.
How do you use a PC power supply for a car amp?
You will need old comp power supply. +12 V is on YELLOW wires. -(minus) or ground is BLACK If you have ATX power supply (that one without wires going to power switch on front - all PC now have ATX) you have to short GREEN and BLACK on main (the biggest plug to start power supply. So use any pair black/yellow to power car amplifier.
What are the values so that over all gain is 10 in instrumentation amplifier?
You need a divider that is 10 to 1. You could use 10 megohms in the feedback and 1 megohm in the bottom leg. Since you are probably talking about an operational amplifier, you need this in both legs.
Which amplifier converts millivolt to volt?
to convert a 100mv to 1volt u will have to multiply it by 10. so u will need a stepup amplifier to do that. u can depend on am op-amp based amplifier to do it if u r allowed to use external supply, else u will need a transformer for the same. Ashish.K

Does a guitar speaker cab need its own power supply?
Typically, the speaker cabinet is powered by the Amplifier. It's the amp that is raising the volume and power to make the speaker move. "Combo" amps have the amplifier and speakers in one box.
How do you use a sony xplode car amplifier at home?
You need a 12volt dc power supply. Be aware that these get very expensive if you need more than 10 amps.
Why does an amplifier need a power supply?
The power supply in either a guitar amplifier or in a professional sound amp reduces the 110v alternating current to a direct current. Also it reduces the voltage that can be used by the speakers, usually 12+ volts. Also if there where no power supply and there could be a possible way of reducing the voltage that could be used in the same was a direct current, you would here a constant phasing type noise from the current alternating. A power supply unit converts power that can be used in correctly in sound frequencies.
Can you hook up an amplifier for a car to a AV receiver for a home theatre system?
It depends on the specific models of each, but typically, Yes. Of course you will need a 12VDC power supply for the amplifier, though. You will also need a AV receiver with a preamp output. You cannot run speaker level outputs into the input of an amplifier.
Can you amplify DC voltages?
Yes, certainly - an operational amplifier circuit (see e.g. Wikipedia) will do this. For instance, a non-inverting amplifier circuit with a gain of 10 will give 1.0V output for 100mV input, 2.0V for 200mV, and so on (limited by the supply voltage of the amplifier). Physical sensors such as thermocouples or strain gauges often need DC amplification to make their outputs easier to measure.
What gauge wire do you need for?
It depends on where the wire is being used, but for the power supply for an ordinary domestic audio amplifier, wire of 0.75 mmsq is adequate, and need to be protected by a 5-amp fuse.
Can I use a preamp into a speaker?
You need a power amplifier in between.

What power of amplifier do i need for 6 ohm speakers to connect them to my computer?
Most power amplifiers will handle a load of 6 ohms. The spec you need to look at is the power handling of the speakers. If they are rated for 100 watts program power, then look for an amplifier rated for 100 watts RMS output. Any amplifier can be connected with adapter cables to the typical 1/8" output of your computer.
