Anatomy of the Power Amplifier, By Robert Zeff
bum replied to Aaron Clinton's topic in The Amplifier Area
Not looking at only one stage of the amp. By the way if you failed to check the wall outlet in your home which should be 120 volts alternating current or close to it but does not fluctuate like that of your so called amp alternating current now why is that? Is it because you were wrong the whole time? Oh buy the way you cannot measure the amperage of d.c unless you have a clamp on amp Metter but digital multi meters will only go to 10 amps usually which is not enough to measure car audio or home a.c. so you must be talking voltage so it proves me right that it is fluctuating d.c. compare it to you home ac that does not fluctuate when in volt setting on a dmm so why does a amp fluctuate. this is cause it is fluctuating d.c. -

The inputs of an amplifier the pure d.c. and the a.c. are shown in this picture notice the dc is just like Bromo’s sine wave pictures same with a.c. picture sort of like his output of a.c. This should be dc if the oscilloscope was set up right. Now here is the output of amplifier before biasing. If you notice the one before biasing does not cross the “0”volts line meaning it never reversed flow like that of a.c. in the wire hence the term pulsated d.c. Since it never crossed that o volt line on the oscilloscope it never became a.c.so it is still d.c. still has a polarity to it which is d.c. which make it a d.c. output. Here is the output of an amplifier after biasing looks like an a.c. sine wave but has a polarity cause it never crossed the 0 volt thresh hold. -

do you got a osilloscope at the shop? have you tryed hooking it to the negtive out put of a amplifier you get nothing from it try it your self. i sure you have not if your claiming it a/c coming out of you amp. your right you hook battery voltage and amps as in pure dc it will blow your sub. there is a differene between ac and dc but there using in amd a trans former to step it up then in the the chip steped up dc. then it is triggered on off like a electronic switch. putting out pulsated d.c. not a.c. yes you can run a sub on ac if it is big enough. volts times amps = watts 120 times a standard 20 amp outlet =2400 watts peak times .707 =1696.8 watts rms has to be able to handle that to do it. which it crosses off more then 3/4 of the subs out there. if your suggesting it is ac i suggest you go back to school and learn some thing. instead of bing a ass hole and lying. -
now you see why i went with the taurus great gas milage over that of a four cylinder. still thinking about a rx8 with a rotory motor can find them cheap. $5-6000. just consered on apex seals etc it like blowing a head gasket when that engine need to be repaired. thren got to rip it down and rebuild it and there know for those going etc.... that probley why ther 5-6000 also thinking old mercury cougar black with a v-8 .
-
ditto then. lol's
-
no problem there thanks for getting back with me.
-
that good for a little four but not enough balls for me my 6 has some good pick up to it some time i think better then a v-8.

if you wire a coil to one chanel and a coil to the other is a big no no. that's if i remember right some thing about them firing difernetly at diferent times will cause the coil to kick side ways? maybe i am thinking two amps who knows. if you want the us amp/ re audio amp just say some thing private message me if you would like it.

i have a us amps/ re audio xt 2000d i mite be willing to get rid of mfg rated at 150 x 1 at 4 ohm 300 x 1 at 2 ohm and 1000x1 at 1 ohm. it puts out. but i am just worried casue it smells smokey. wish i had the money right this second to ship it to you for free i would give ya the amp free too. i got 15 bucks right now to my name lol's till i can get paid. i am wondering if that $15 would cover shipping to ya. i just don't know if it would . if so i would have to dig up the recipet on e bay and find the remote bass knob for it and the booklet does not have a box any more tossed it. i do got money just don't want to touch it cause it saved for a car. lol's. i could try usps shipping. pm me if you want it. it works i just got to dig up the e bay recipet. and pay for the shipping.

liked the video thanks good tuneing job sounds clean on my net book mic. to bad i do not got the home theater to listen to it threw here. any ways talk to emery see if that sub or amp can handle the amp bridged to the sub i am assuming you got either a s4 or d4 coil for the dcon if it is a s4 you may be able to bridge it to get more power out of it. that why i said get the s4 you only will need one sub for sound quality. it will be even louder in the ported box. that were i think you will only need one. if it is a d4 all you need is a amp. i got one but it smells smokey and don't want to sell it to you cause of it. i got it on e bay for 115 nib mite have been refurb nib who knows.

did he get the s4's or the dual 4 ohm coil? and if he got the s4's is his amp bridgeable to one channel? if it is he should have goten just one s4 coil sub and bridged it? or can he just do it? for some reason if he has a bridgable amp i do not think he will need two subs i think one is perfect for him. output will be better in ported then two sealed. i think. any ways think about it

I know one! It starts with an "H" and ends with "onda" how many mpg's does your honda get is it 31-32? my taurus gets 26-28 mpg. love when they brag about fuel econmy and it that good for a v 6 to have that kinda of gas millage aginst a l4. see my point it not just american cars even thinging a japenese car mazda. i will not list yet just wondering if i am missing any thing and am thing hard aboutthat mazda.

yes they are. once you get past i need spl stage of youth and find you only need one d con and not 8 z- con's. they sound awesome for what it is. love my d con to death and would not let it go. i have always wonder about a 8 inch d con. but that's up to aaron and his time frame. i know he has not enough time lately with work and all. any ways emery what about thos brovox 8 's if any thing if you do not want them/one i am going to throw them in a band pass. and enjoy them my self. let me know sooner or later. if you want them. i am betting the tang has more x max so it will hit harder then the brovox so you get what you want.

Last I thought, that was an Aussie car under that Pontiac badge. most likely right there aaron just looking for a good car name if any one has any.
