What is a power amp?

Question

What is it and what use would i buy it for?

Answer 1

A power amplifier is an external - and usually rack-mounted - device that can be used to further the amplification of the player. Usually power-amps are run from a mixing board, where the guitar signal is located, where it then sends out another signal to external speakers usually located above the stage, or surrounding the stage area. PA systems also use this type of amplifier, but many times the PA amp isn't run through a mixer...unless there's going to be a significant amount of after-effects being added to the singers voice.

Most common club power amps push roughly 1800-2500 watts, and one is generally more than enough to fill a small concert hall with plenty of sound.

Answer 2

Well , one of two things. Either a power amp designed in conjunction for use with a PA system (as with a mixer), or a guitar power amp, meaning a separate power amp and a preamp combination , mostly considered in a "rack mount" setup where you have a rackspace box (or container..if you will) where you have a preamp, power amp, and maybe even some rackspace sized effects processor, power supply, etc...

Answer 3

A power amp does just that, provide the power. It doesn't have any controls other than on/off. You also need a pre-amp to connect other equipment.

Answer 4

It's an electrical appliance that makes a sound system's volume audible (loud!). For DJs and home theaters it powers the house speakers, connected to them by wires. For musicians, it's sometimes in the same box with speakers and you hear their instrument through it.

Answer 5

It's a piece of electronic that enhances music signals It amplifies music. you can buy one and install it in your car .
