Hindi mo kaylagan ng oscilloscope tester lang pag mag sound ka lagyan mo ng tester ang output ng amp ilagay mo eto sa dc at patugtugin mo hangan sa kaya ng speaker mo tignan mo ang tester kung may lumalabas na dc depende kasi sa bias ng isang amp kung ilan dc volt ang lumalabas , pag may dc lumalabas mali ang bais ng amp mo or hindi gumagana ang protection ng amp
tsk,tsk. destructive testing pala.
so kahit walang oscilloscope, malalaman mo kung ilang Vpk-pk bago mag-dc out? tapos kung ano ang cause ng dc out?  kasi kung may oscilloscope ka, madali lang malaman kung saan nagsisimulang mag-dc out at ang cause. (asymmetrical clipping, asymmetrical gain, asymmetrical clipping when using low z loads, asymmetrical gain when using low z loads etc.)

Hindi naman sa ganon, basic lang ang sinasabi ko mas madali gumamit ng tester ,hindi kasi lahat marunong gumanit ng oscilliscope at mahal eto ,kapag tester halos lahat mayron tayo, pag makita mo may dc out thats the time gamitin mo oscilliscope pag wala naman dc out you dont need a oscilliscope :-D

Sir eirol try mo lagyan nang tester ang output ang amp mo na analog ilagay mo sa ac muna makikita mo na parang vu meter pero ilagay mo sa dc pag naging vu pa yung tester mo ay naku sir pa check mo na yung amp mo sira yan

try mo yan on all amps.. tyak same results

it doesn't mean na pag may reading ka na sa dc voltmeter sa output ng amp with a signal is dc voltages na yun..

so you mean that there should be no reading sa dc voltmeter sa output ng isang amp with a signal?

Yes dapat wala talaga if mayron dapat below 1 v kung mas maganda 0 volt yan ang tama sa isang condition na amp hindi masusunog ang speaker pag ac volt. you can ask a qualified techician if you want, if you dont belive me am just concern lang sa inyo para safe ang mga gamit niyo

agree with that if there is no signal sa amp, ie amp is in idle , pero if may signal and use a dc voltmeter iba na yun..

lipat na kaya natin itong technical issue dito http://www.electronicslab.ph/forum/  mas maraming tech people na makakatulong

Kahit may signal dapat below 1v or 0 v ang isang amp sa dc ac walang problema mas mataas na ac mas lalakas na power pero kapag dc patay tayo dyan sunog ang voice coil mo :-D

sir, sa experience ninyo, ilang volts pumapalo yung DC level pag nag DC out yung crell?

yes but what i want to say is that you cant detect dc voltages sa output ng amp with a signal using only a dc voltmeter... may reading ka sa dc voltmeter but u can't say it's dc

Tester na yun bro pag nasa dc ka at pumalo ang tester eh sigurado kang dc yun maliban lang kung sira ang tester mo hindi kasi papalo ang tester mo kung ac ang lumalabas sa amp  :-o

D mo masasabi how many watts na may dc out ilagay mo nalang tester mo sa 50 v dc tapos lagyan mo ng signal untiunti mo lakasan ang volume para makita mo sa tester kung may dc volt na lumalabas pag maron pa check mo na baising

sir, tanong ko ulit, ilang volts dc ang naexperience nyo na lumabas sa crell?

Pag bumigay na ang amp kung ano ang voltage ng supply yung ang lumalabas , kapag may konting tama lang 12v above ang voltage na lumalabas kapag mag pick

eyng, yung actual sana sa experience nyo sa crell ang tinatanong ko sir kasi sa mga responses nyo parang na-measure nyo na dati.  anyways, base sa quoted reply, ibig sabihin naglalabas ng more than 110VDC ang crell?

Yes sira nga dapat kasi nag clip ang relay pero hindi gumana protection nang amp kaya yon sunog ang mga speaker

ilan naba dito sa ka PM ntin ang nasunugan ng speaker ng dahil sa Crell n nag DC,,TAAS ANG KAMAY,, ,,kc ako ok p nman mga speaker ko at gamit ko crell ca25 at meron pa akong Ca8...yong friend ko 2 ang ca20 nya ..ung isa 4 n paudio SD18el ang load at yong isa 4 n crown JH186 ang load at morethan 1 year n sa kanya at panay pa ang labas ng sounds nya ehh bakit wla nmang nging problema......... :evil:

this is the moment guys... mag kakaAminan na... kung totoo b ang tsismis , kuro-kuro about Crell's...masasagot na ang mga tanong na: bakit madami ang nagbebenta nito? at ang mga bulong-bulungan about the product?  base sa mga nakagamit na... TAAS na ANG KAMAY.... AMININ boys....

kami gamit namin ay 2 crell ca 20 pero so far di pa naman kami nasusunugan ng speakers, minsan pag wala mga boss nilalakasan pa ng mga boys lalo na pag may ibang system na nakaset-up na kaharap.. hehehe

ot: may nakasubok na po ba ng tasso i12 dito? it has 4 step class H circuitry na mejo qsc topology ang circuit. mejo mahal din ata sa market ito kasi tasso is maybe 1 of china made na mejo quality.. any comments?
