[@romeovelasco4151]

Pwede po bang gawing pre-amp yan para maka boost ng mahinang signal?

[@impopio4987]

pano maiiwasan ang humming, buzzing , hiszing noise?.. sana mapansin..thanks

[@masterdorbus]

make sure po regulated ang power supply, isa rin un cause ng humming. isa pa sa wiring, make sure shielded lalo ng ung sa mga inputs make it as short as possible.

[@barriosytube3242]

ang galing mo naman ka breaders.. pwedi mo ba yan gamitin sa bahay ko.

[@masterdorbus]

[@infoandroid6792]

Add 470/25 volte condenser on power supply for good punch

[@masterdorbus]

Thank you for the info.. I try soon boss...

[@infoandroid6792]

I need same kit line pam8403 but 100 wat do you know?

[@christianlabad9651]

Boss ilang watts dapat speaker nyan meron kasi decoder na mp3 bluetooth kaso naggaralgal kapag ginamit ko na kasama yang pam8403

[@masterdorbus]

Dapat ang speaker nya is 3 watts din or mababa sa 3 watts.. Ang PAM8403 ay may output na 3 watts per channel kaya dapat laging mas mataas ng 50% ang power rating ng amplifier versus speaker, for example ang amplifier mo is 750 watts dapat ang speaker mo ay 500 watts.. Tapos make sure ang wire na gamit mo galing MP3 decoder module papuntang PAM8403 is shielded tapos wag masyadong mahaba ang wire papuntang speaker. Masyado kasing prone sa distortion and interference ang amplifier na to..

[@prof8957]

Pede po ba gumawa ng 2 PAM8403 board magkaparallel sa iisang input at 4 na speakers?

[@masterdorbus]

sa tingin ko pwede yan master, ano po purpose? bakit need mo dalawang board? saan mo po gagamitin?

[@prof8957]

@@masterdorbus> para po sana sa 2.1 soundbar ko na nasira ang board

[@masterdorbus]

@@prof8957 pwede yan, kung may available sana ko dito na mga PAM8403 amp board gagawa ako ng video para makita mo muna

[@ibinoshow]

Ang galing naman niyan master he he ....

[@brunomarvs]

boss ung 5watts na speaker ng sirang bluetooth speaker kaya din ba nyan?

[@masterdorbus]

kaya yan boss wag mo lang sasagarin..

[@brunomarvs]

@@masterdorbus kung left and right 5watts kakayanin din po kaya?

[@timothyjustinsawali2737]

Dalwang 15 watts speaker po kaya. kaya papo

[@masterdorbus]

Kaya yan

[@timothyjustinsawali2737]

Hangang ilan po kaya ang waatage ng speaker na kaya nyan po

[@masterdorbus]

Mga 10 watts na speaker sa tingin ko kuha pa ang magandang tunog nyan ung hindi sabog o gumagaralgal.. Kasi kahit mga 30% lng ng speaker wattage rating ang iapply mong power sa kanya maganda pa yan.. Mababa nga lang ang SPL (sound pressure level) or "loudness" na tinatawag.. Matagal ko na sana gustong gumawa ng video nito actual busy kasi ko ngayon sa ibang bagay master...

[@furogrealty4025]

Techy...

[@needlethread4715]

sira din ba agad ic nito pag nareverse polarity ang power supply?

[@masterdorbus]

sira yan boss kasi walang reverse polarity protection yan.

[@needlethread4715]

@@masterdorbus ah sige po sir. salamat po. bumili din ako pero yung may volume pot na.

[@masterdorbus]

@@needlethread4715 oo mas maganda yon..

[@michaelyabes4133]

sir pwede na gamitin yung celpon charger na 5v?

[@masterdorbus]

Yes master.. Pwedeng pwede

[@michaelyabes4133]

isa pa master pano pag yung speaker eh 2ohms 5watts.. pwedeba sya gamitin?

[@tossancuyota7848]

boss may link kaba san mo binili sayo? andami kasi fake eh meron ako na order kaso not working sa 4ohms load gusto nya higher load like 6ohms to 8ohms

[@masterdorbus]

wala na boss, nung nasa abroad pa kasi ko nyan.

[@jonfixalot968]

Paano po sir kung isang speaker lang gamitin??kailangan po ba ng bridge?paano po gawin?

[@masterdorbus]

Ito sir baka makatulong, theory ko pa lang ito di ko pa sya nagawa actual, here's the link kzbin.info/www/bejne/gWrRaGhjiq1rmpI

[@arcellaforteza2600]

master pwedi ba yan ilagay sa head set?

[@masterdorbus]

di ko pa nasubukan master, pero theoretically, di siguro sya magbibigay ng magandang tunog kasi ang PAM8403 ay pang loudspeaker amp. saka sa datasheet nakalagay 3W para sa 4 ohm load, typically ang mga headphones ay nasa 32 ohms yan.

[@Daaikii]

boss may idea ka paano i mono yan

[@masterdorbus]

Saan mo gagamitin master bakit gusto mo sya gawing mono?...pwede siguro convert mo muna ang audio source from stereo to mono saka mo ikabit sa left and right input ng PAM8403 amplifier

[@Daaikii]

@@masterdorbus di boss sa mini speaker ko rin sya gagamitin ang kaso yung nasirang board ng speaker eh mono lang ipapalit ko tong PAM8403 kaso dalawa channel nya baka may ibang sound na di madetect kasi nasa kabilang channel kaya ko natanong kasi kung ganun i momono ko nalang kung pwede or mag aad ako bagong speaker

[@masterdorbus]

@@Daaikii master eto gumawa ako ng vlog baka makatulong thanks kzbin.info/www/bejne/gWrRaGhjiq1rmpI

[@montonmonton4855]

nasa magkano ganyan boss

[@masterdorbus]

Di ko na tanda boss, mura lang yan..

[@montonmonton4855]

100?

[@masterdorbus]

Di aabot ng 100 pesos yan. May nakita ko sa shopee 28 pesos lng ang iba 50, iba iba kasi presyo ng mga seller. shopee.ph/product/226548939/5317732352?smtt=0.239869594-1624130962.9
