Controlling your Car Stereo Amplifier Power

Video Transcript
"Power! What does that mean to you? On an amplifier that means everything. Let's talk about power supplies a little bit. Most amplifiers use a power supply called a fet or a power transition devise called a fet. They have capacitors they have coils. In order to make the power, the average conducting devise is a fet and fets require a heat scene. That's fine for the average consumer. Ninety percent of the amplifiers you find out on the market fet driven amplifiers but the problem with fets are that they heat up and for extreme SPL, sound pressure level competitions or people that live in very hot areas, at times it can be a disadvantage. That's one type of power supply. This amplifier is an amplifier that uses fets. It's kind of older technology, it's reliable though, it's affordable and that's what you're going to find ninety percent of the time. Let's talk about this next power supply. I get a balance of good and bad. This amplifier again the Zabco, it uses a stack board design, it uses bipolars. Bipolars are exactly it, bipolar transfers from one side to the other side power so it bleeds off heat. It's a little more efficient, requires less space but then again it costs more money. It's been in existence for quite a while but it took the genius of Edward Zeff, yes I'm a nerd again, to do it correctly. Vacuum tube amplifiers, there are many on the market. It's a trickling of technology down from home stereos. Vacuum tubes are the warmest possible amplifiers solution you can get but they require a large amount of size and they are prohibitively expensive. I mean they are expensive! More expensive than this, you thought this was expensive, go by a Butler tube amp and you'll see what expensive is. Not a whole lot of power out of vacuum tube amplifiers but you will get the warmest sound reproduction. Mosfet's they can produce massive amounts of power, but they have the short coming of heat. Bipolars, cleaner transition, immediate power with less amperage draw but expensive again. It gives you a balance between vacuum and Mosfets with just awesome transition and more power capability."
