Help po, ano po possible na sira ng videoke set if nawawala lagi ang bass? twitter lang natitira.

Kakapalit ko lang ng 2 capacitor sa circuits from output ng amplifier ito yung near 12" speaker.then renew ko yung solder ng 2 circuits.

napagana ko naman sya,mga 2 times palang naarkila itong videoke,bumigay nnman,wala nnman bass.

amplifier output po b ang problem nito at maaring may sira sa amp nito?

please help, thank you....

na try po nmin sa iba speaker,gumagana sya...

dun nga pl sa speaker ng vid. aligator ang connector.natutunaw yung plastic n red.

possible ba n maluwag lang kaya itong aligator kaya umiinit,
connected po ba sa crossover or dividing network yun,
kaya bumigay mga hinang ng divider/crossover?

sa amp. po b, pano malalaman if the output nito are still good?

during testing ng speaker sound last day,pagbukas namin kahapon may bulging nnmn n caps.colapse yung top and bottom portion ng capacitor

kaya now lagay ko paralel muna yung speaker na wala devider dun kasama sa isang devider na good

mahina na lang output ng sound

observe ko kung ano mangyari...

irestore ko parin yung sira n devider.

thanks sa reply....

tunaw? baka masyadong malaki output nung amplifier 'di kaya nung mga capacitor.

pwede ring mababa impedance nung speaker than rated nung amplifier, mas magiging mataas 'yung current kapag maliit impedance nung speaker. bawasan muna volume input sa bass (sa tone control).

partial lang naman yung tunaw,bale indication lang na uminit itong aligator,

yung plastic na red and black,ito yung pang higpit ng out ng konzert amplifier punta speaker.

ok hinaan ko muna yung bass,thanks...

bale dating good naman performance nito so now lang nag kakaproblem.

yung mga caps n NP 100v mahirap hanapin hindi available dito sa amin.

speaker ko 2 pcs. konzert KW-3000M Dual impedance 8 ohms, 350 watts peak

yung devider nmn Crown CN-330, 300W max.

thanks sa reply...

Rekta na yung subwoofer sa amp,filter nalang yung twiter and mid range parallel.

safe po ba itong divider na ito?

bigay sakin ng co work ko,ganto daw gamit nya sa sound system nya.
