Ask Sir Tony - an Electronics/Electrical Q & A thread

  • hi question po, may home theater subwoofer na binigay sa akin, 50hz lang yun nakalagay, magagamit kaya dito yun? 50/60hz sa pinas di po ba?
  • pahabol pala 240v 50 hz
  • Yes
  • Mga sir, tanong ko lang po, ano po dapat size ng main breaker ko kung ang size ng wire ko papuntang poste ay #10gauge lang, ganyan po kasi mga wire mg residential sa tondo yung mga orange wire po. Sabi kasi ng electrician na pinagtanungan ko dapat daw 60A which i doubt kasi based from my research #10 wires are for 30A circuit breaker only, Please correct me if im wrong.
  • Hi guys, good day!

    Saan po kaya may available na ganitong cable?

    9-Pin DIN - Male (both ends)




    I tried lahat ng mall sa ortigas, mandaluyong, wala ako makita huhu
  • ^I don't even have any idea what that kind of cable is used for, but it's seems uncommon since even looking online such cables are hard to find. However, RS Components (<click here for link>) is selling 9-pin male DIN cables BUT only one end has the male connector, the other end is free-ended (wires only):




    If you're desperate you can splice two such cables together to create a dual-terminated male 9-pin DIN cable, the wires are color coded anyway and you just need to solder together the wires of the same color. I have no idea how it affects performance of the cable though. Or, if you can find a solo male 9-pin DIN connector, that would be a ideal. Mouser (www.mouser.ph) sells one (Kobiconn mini-DIN) but looking at the pin layout (PDF here: <click here for link>) versus that of the one being sold at RS Components, this connector has a different layout. Seems the 9-pin DIN configuration is NOT standardized.

  • Sir, question ko lng tungkol sa Videoke system ko.. napuputol ang sounds kapag nilalakasan ang volume which is kapag normal ay ok at maganda tunog. Ang Aplifier and Video player ko ay nakahiwalay sa speaker ko na 2 sets.

    her is my videoke parts and spec.
    - AMplifier = KONZERT 502 (Original)
    - Speaker 1 set = 500WX12 (1) and 300WX10 (2pcs)
    Pls help me..
    Thank you..
  • ^
    Sir baka sa amp mo under power yung output. Baka di match power ng speaker and amp. Susuko amp mo pag masyado na malakas
  • Sorry. Mukhang match naman. I just checked your amp specs. If match naman talaga. Maybe there is somthing wrong. Sorry not so expert. Hanggang dito na lng ako. Hehehe
  • Speaker 1 set = 500WX12 (1) and 300WX10 (2pcs)
    baka mali ang ohms nyan? kundi baka sobrang lakas na nag cli clip na yung amplifier? pagka nagkakaroon na ng distortion tapos pinabayaan mo na malakas pwede masira yung ampli at speakers...
  • Anong nagiging sira ng usb flash drive kapag hindi madetect ng laptop ?
  • napuputol ang sounds kapag nilalakasan ang volume which is kapag normal ay ok at maganda tunog.


    amp issue yan... tawag dyan ay clipping at madalas di kaya ng amplifier yung speaker na nakakabit...

    - Speaker 1 set = 500WX12 (1) and 300WX10 (2pcs)


    ilan daw watts yung power output nung amplifier? RMS power output at kung may peak power output in wattas na sinabi.... kelangan malaman mo kung ilang watts ang power output nung amplifier para malaman kung matched ang speakers dun.
  • Maaari bang mag short circuit a desktop/laptop

    o Tamaan ng power surge o maspike,

    kapag ang live outlet ay may power saver and power strip

    at nakakabit naman ang Device sa avr ?
  • @aybee102

    If the voltage spike is high enough (like a lightning strike), anything is possible. :O

    Also, you didn't mention a surge suppressor.
  • Ask ko lang guys kung ano magandang alternative sa surge protector. Wala kasing pang 3rd prong(ground) mga outlet namin dito sa bahay. Lumang wiring na. Pang desktop computer sana.
  • Avr? Yun talaga ang nirerecommend na gamitin sa desktop computers diba?
  • Asking for advice/assistance.
    May binili ako na Razer Leviathan for cheap dahil may slight issue. An sabi ng seller nag auto off sya dahil nagkakaroon daw ng overheating.
    Tested the unit and umaandar naman sya pero after 30 mins namamatay nga and kung ittry ko ulit i-on ayaw na unless ipahinga ko talaga sya ng ilang mins.

    Tried firmware update with the auto off function disabled. No luck.

    Sa ngayon I dismantled/opend up the unit (since out of warranty na sya kaya lakasan na lang ng loob hehe!) and ask ko lang kung ano dapat ko icheck or tignan na possible cause ng auto shut down nya. Overheating ba talaga? Tried placing new thermal pastes dun sa mga chips sa loob na nakita ko na may heatsink pero ganun pa rin.

    Salamat po sa makakatulong.
  • ...mayroon po bang nag se-rservice ng soldering ng chipset bandang Dau/Mabalacat Pampanga?
