Electric Amplifiers

 

 

 

 

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). An amplifier uses electric power from a power supply to increase the amplitude of a signal. The amount of amplification provided by an amplifier is measured by its gain: the ratio of output to input.

 

 

 

 

Amplifiers Speakers:

Speakers typically carry ratings between 4 and 8 ohms. Amplifiers generally operate effectively in a specified range: say, 4 to 16 ohms. Check your specs, but when that’s the case, connecting a speaker rated between 4 and 16 ohms will be OK.  

POWER AMPLIFIERS

 

  

 

 

 

An audio power amplifier (or power amp) is an electronic amplifier that strengthens low-power, inaudible electronic audio signals such as the signal from radio receiver or electric guitar pickup to a level that is strong enough for driving (or powering) loudspeakers or headphones.

 

DJ Amplifiers:

 

 

Stuck understanding PA systems? Need to rent or buy one for your shows? Scared about plugging into or playing on a PA? Want to know why you need one at all, when you could take your home stereo speakers to the party and use those instead? If so, trust me – you’re not alone. 

 

wires:

 

 

 

 

Speaker cable is the wire used for the electrical connections between speakers and amplifier sources. It has three key electrical properties: resistance, capacitance and inductance. Resistance is by far the most important property to look at. Low-resistance wire allows more of the source’s power through to the speaker coil, meaning more power and more sound. Simple enough.

etc:

The first practical device that could amplify was the triode vacuum tube, invented in 1906 by Lee De Forest, which led to the first amplifiers around 1912. Vacuum tubes were used in almost all amplifiers until the 1960s–1970s when the transistor, invented in 1947, replaced them. Today, most amplifiers use transistors, but vacuum tubes continue to be used in some applications.
