Can you run an amplifier with a power inverter?
Most likely yes depending on your inverter and how long you run it. I have done it once before. I ran a sub woofer and a PA horn in my dad's work van for fun. Ran it for about a half hour. It was a 1000 watt inverter on a 700cca battery. The amplifier was bridged to 150 watts RMS. If you run more power you might need a bigger inverter. Out inverter also has circuitry that filters out noise.

EEG?
DefinitionAn electroencephalogram (EEG) is a test to detect problems in the electrical activity of the brain.Alternative NamesElectroencephalogram; Brain wave testHow the test is performedBrain cells communicate with each other by producing tiny electrical impulses. In an EEG, this faint electrical activity is measured by putting electrodes on the scalp.The test is performed by an EEG technician in your health care provider's office, at a hospital, or at an independent laboratory. You will be asked to lie on your back on a bed or in a reclining chair.The technician will apply between 16 and 25 flat metal disks (electrodes) in different positions on your scalp. The disks are held in place with a sticky paste. The electrodes are connected by wires to an amplifier and a recording machine.The recording machine converts the electrical impulses into patterns that can be seen on a computer screen, as well as stored on a computer disk. Before computers, the activity was printed on paper. In either case, the electical activity looks like a series of wavy lines. You will need to lie still with your eyes closed because any movement can alter the results.You may be asked to do certain things during the recording, such as breathe deeply and rapidly for several minutes or look at a bright flashing light.How to prepare for the testYou will need to wash your hair the night before the test. Do not use any oils, sprays, or conditioner on your hair before this test.Your health care provider may want you to stop taking certain medications before the test. Do not change or stop medications without first talking to your health care provider.You should avoid all foods containing caffeine for 8 hours before the test.Sometimes it is necessary to sleep during the test, so you may be asked to reduce your sleep time the night before. If you're asked to sleep as little as possible before the test, don't consume any caffeine, energy drinks, or other products that help you stay awake.How the test will feelThis test causes no discomfort. Although having electrodes pasted onto your skin may feel strange, they only record activity and do not produce any sensation. No significant electricity passes from the electrode into your skin.Why the test is performedEEG is used to help diagnose if you're having seizures and if so, what type. An EEG is also used to find the causes of confusion, and to evaluate head injuries, tumors, infections, degenerative diseases such as Alzheimer's disease, and abnormal changes in body chemistry that affect the brain.It is also used to:Evaluate problems with sleep ( sleep disorders)To investigate periods of unconsciousnessTo monitor the brain during brain surgeryThe EEG may be done to show that the brain has no activity, in the case of someone in a deep coma. It can be helpful when trying to decide if someone is brain dead.EEG cannot be used to measure intelligence.Normal ValuesBrain electrical activity has certain frequencies (the number of waves per second) that are normal for different levels of consciousness. For example, brain waves are faster when you are awake, and slower when you're sleeping. There are also normal patterns to these waves. These frequencies and patterns are what the EEG reader looks for.What abnormal results meanAbnormal results on an EEG test may be due to:An abnormal structure in the brain (such as a brain tumor)Attention problemsTissue death due to a blockage in blood flow (cerebral infarction)Drug or alcohol abuseHead injuryInflammation of the brain (encephalitis)Hemorrhage (abnormal bleeding caused by a ruptured blood vessel)Migraines (in some cases)Seizure disorder (such as epilepsy or convulsions)Sleep disorder (such as narcolepsy)Note: A normal EEG does not mean that a seizure did not occur.What the risks areThe procedure is very safe. However, the flashing lights or fast breathing (hyperventilation) required during the test may trigger seizures in those with seizure disorders. The health care provider performing the EEG is trained to take care of you if this happens.It may be difficult to get the paste out of your hair, but it should come out after a few washings with regular shampoo.ReferencesTrescher WH, Lesser RP.

What are the big speakers at a concert called?
They are called "PA" speakers. PA meaning "Public Address" is a large loudspeaker design to deliver sound to a large group of audience. You'll often see these large speakers at clubs, concerts, and cinemas. There are two types of PA speakers. "Passive" and "Active" speakers. The passive speakers doesn't have a built-in amplifier. These speakers will require the use of a power source called an "Amplifier" to power these speakers. The active speakers have a built-in amplifier and doesn't require the use of an amplifier.

Adjust the amplifier settings to achieve the desired level of amplification without introducing distortion.
How do I bridge my Stereo PA amplifier to run one 8 ohm Sub-Woofer?
Bridging two amplifier channels is a way of delivering more power to a single speaker. A two channel amplifier might have a power output of 100W per channel. By linking them together, the power output to the single speaker can increase to 200W. It's not always quite that simple. If the amplifier can be bridged, it will say so in the manual and it will show the connections that need to be used. Trying to bridge an amplifier that is unsuitable is a sure fire way of killing the amplifier and perhaps the speaker itself. There are certainly methods that can be used to bridge amplifier channels even if the manufacturer does not offer the facility. To do so needs an intimate knowledge of the electronics used in the amplifier. The fact that this question is being asked indicates that the required knowledge isn't there right now. Much safer to obtain an amplifier that is rated and approved for bridged loads than risk the unpleasant results of getting it wrong.
