Amps

Discussion in 'Amps and Cabs [BG]' started by morty25, Jul 7, 2002.


  1. Can any one explain to m what cabs and heads are and how they connect. i hear people talk about them but im sorta confused! :confused:
     
  2. simplified explanation for all electric guitar and even PA rigs:

    there are 3 basic parts to amplification: a preamp, a power amp, and the speakers

    a preamp colors the original signal (and amplifies it in its signal form) and alters it and sends it to a power amp. the effects of a preamp can be as simple as a 5-band equilizer before a PA, or it can be a tube-filled circuit with extra stages to add warmth or distortion to your sound.

    a power amp takes AC power from a power source (usually a wall socket) and turns it into DC power, and amplifies the signal from the preamp into DC watts, and sends it to the speakers.

    the speakers move the air which actually creates your sound.

    a head is usually defined as a preamp+a power amp designed to complement each other sold or made into a single unit, so you can plug your head into the wall, plug your bass into the head, then plug the head into some speakers and blast away.
