surround speaker?
« on: April 24, 2008, 10:50:51 PM »
sino po mahilig dito ng ganitong set up ng audio? meron kasi akong ginagawa sa mga audio system, normally kasi ang set up sa left and right speaker eh ang connection sa black and red ng kada output, pero yung giangawa ko eh nagdagdag ako ng isa pang speaker at dun ko kinakabit sa dalawang red. pag maganda ang audio quality lalo na yung cd audio eh iba yung tunog na luamalabas dun sa speaker. me mga gumagawa ba nito dito?

ang lumalabas sa setup mo is kinda like a center channel (theoretically)
kc ang center channel is combination ng FL and FR pero this is done
during the signal processing inside the unit. kasi the center channel is split
in half (each resultant is 3dB lower than the original) then the identical version
of the waveform are added po sa both left channel po at right channel
basta ang remember nyo lang po na sa regular dolby processing
Lt and Rt contains exactly  half of the center channel information.
pasensiya na po kung medyo magulo explanation ko  ;D

kuya anu po ba magandang connection sa spk?? parallel or series connection???
gusto ko po kasi kabitan ng isa pang spk un spk ng computer ko para maganda po un sound...
tpos kuya bakit may noise ung spk ng computer ko??? panu po natatanggal un, nag palit na po ako ng spk sa loob
pero ganun pa din po??

@danny

anu bang magandang set up ng home sysytem? like gamit ko eh yung dvd player lang? me mga nakita kasi ako na 7.1 audio sysytem. siguro meron pang mas magnda dun.

what are your tips para sa magandang audio system sa bahay?

TIA

yung regards po sa connection ay depende po iyan, una po muna
anong klase po ba yung system na ginagamit nyo sa computer nyo?
yan po ba yung may subwoofer at two set of spkr (Left and Right)
or complete surround system? are you planning to put another
woofer inside the cabinet or mag lalagay lang po kay ng isa pang box?
Depende din po sa load impedance ng amplifier yan (assuming na may amp ka)
nde po tau pwede mag kabit basta basta kung ma ooverload naman ang amp po ninyo
always check po yung load imp. ng amp muna.

@ahlburuto

kung simple lang po ang gusto nyo na set up, ok na po yung
cnasabi nyong 7.1 na audio system, usually kasama na lahat yun
isang set na surround speakers and yung pinaka unit mismo.
if ever naman po na mas gusto nyo na mas maganda, I will go with
sepaerate components. You can't go wrong with separates po
kasi mas napipili nyo po yung each unit based on you taste.
most of my clients go with separates, pero meron din naman
pong gumagamit ng HTIB kung maliit lang ang space nila sa haws nila.

@mahalkosinikki

for generic PC speakers eto ginawa ko dati.

nagdagdag ako dati ng filter capacitors sa supply nung speaker ko. then naglagay ng low pass filter, wala kasing filter yung PC speaker ko galing amplifier papunta sa speaker kaya parang added noise yung high band audio.

pwede ring nagcli-clip yung output nung amplifier, tinaasan ko ng konti yung supply from 12V to 18V.

tama, pag walang filter or nde maganda anf filterization
may noise ka nga na maririnig, usually humming or buzzing sound.
this is also really true sa mga big power amps. madami na po akong nagawang mark levinson amplifier
filter palagi ang problem correct c rdpzycho,    :)

OT:

eto pa yung mga pwedeng improvements for generic PC speakers para pwedeng gamiting satellite speakers sa 5.1 or 7.1 setup on a tight budget. BTW, some generic PC speakers are monaural, mukha lang stereo yung cable pero shorted sa speaker box mismo.

1. yung speaker ko 12V ang supply, rectified and filtered lang. maliit yung filter capacitor, linakihan ko (pwede rin yung capacitance multiplier o mag-regulator na lang). then pinalitan ko rin yung transformer para tumaas ng konti ang supply, parang nagcli-clip kasi yung sa output pag todo volume. lagyan din ng maraming bypass capacitors.

2. walang crossover network majority ng generic speaker. midrange lang maganda tunog nung kasamang maliit na speaker. nakakuha ako ng crossover sa lumang speaker box na nakita ko.

3. ang normal amplifier nito 2 TO-92 transistors plus isang TO-92 buffer. pwedeng palitan. pinalitan ko rin yung wattage ng mga resistor, lalo na yung swamping resistor. 5W ang maximum na na-draw ko dito with nearly 20V Vsupply.

4. pwedeng palitan yung input buffer ng differential amplifier para bawas ang common mode noise. LM358 can do the job.

5. kung gagawin talagang satellite speaker mas maganda kung magdagdag ng tweeter. PhP 25 ata ang isa. crossover network lang ulit.

6. subwoofer na lang kulang at pwede na yung setup for a little bit decent 5.1 setup for PC. might not be Hi-Fi but it does the job. hindi ko pa tapos yung setup ko. aayusin ko rin kasi case nung generic speaker. luma na kasi. ;D virtually free yung magiging setup sa PC ko. huwag lang sana akong tamarin. hehehe.

@rdpzycho

minsan kaya po nag ciclip pag mababa ang current rating ng transformer, you might wanna check it.
I've seen a lot of those na ganun po ang kaso, power supply problem.
Increasing the voltage is ok, but not much, depende kc s design specs. so that is another
thing to watch.
putting a crossover is a good idea, diff amp is always good compare
to an ordinary lang.  ;D

btw, if you have more space, try to make the supply of the op amp maging regulated.
kailan mo ccmulan ang project mo?
hehehhe post po kau ng pic d2  ;D ;D

started mid last year and counting. ;D hindi ko na kasi natutukan madaming ibang ginagawa. almost one year na pala. ;D

larger transformer na yung gamit ko, ang laki ng drop sa voltage pag mataas volume dun sa original transformer. pag-iisahin ko lahat nung amp ng supply. pag may makakahoy akong ibang parts baka speaker at case na lang mapakinabangan ko, yung amp na kasama, lagay na sa bin. ;D pero with the present modifications (additional filters), mas ok na yung sounds compare sa dati.

lately, nakakita ako ng murang generic speaker na maganda aesthetics nung case. balak kong bumili, sana lang hindi mono tulad nung ibang speaker na nabuksan ko. >:(

yung subwoofer hindi ko pa alam kung ano gagawin kong enclosure. merong kasing dalawang 8" driver sa bahay. luma na, napapalitan na yung goma. tinest ko dati buo pa naman ang tunog, nagtitipid ako ngayon kaya ayaw ko na ring bumili ng 12" driver. meron ring lumang sharp amplifier sa bahay, baka yun muna gamitin ko for the subwoofer. problem lang made of wood yung kwarto ko. kapag malakas ang bass naririnig yung panginginig ng kahoy at nung bintana. ;D

pag ginawa ko na ulit kuha ako ng pics. ;D

naku ang tagal na pala hehehe alam mo
ganun din po ako pag may project, taon inaabot hahaha.

so madami ba talagang computer speaker na nka mono?
mga fake pala kung gnun nde tunay na stereo kung nka tap lang.

meron nga palang software na free s internet para ma compute mo yung
box for your subwoofer, meron ako nun dati kaso na delete ko.
nde ko lang alam kung supported ang two woofers.
gamitin nyo po ung 2 woofers nyo para nde na nga kau bibili.
I will try to look for that software kung nasa isang pc ko pa.

kung made of woods yung room mo, I guess you are out of luck   ;D ;D ;D
nde ka makaka pag lakas dahil madidinig ng kapitbahay mo ung rattle ng room mo  ;D

cge we will be waiting sa mga pics mo hehe

meron din akong ganung program dati. pero nabura nung nagformat kuya ko. :'(

maraming mono na computer speaker. kakabukas ko lang nung dito sa office mono din. :'( pero madali naman replicate yung circuit nila para gawing stereo. ;D

madali nga palang makita 'to sa Generic PC Speakers. kapag tinaas niyo yung Volume at yung Power LED sumasabay sa Bass, ibig sabihin dapat palitan yung Transformer or gawing malaki yung Capacitor (pero hirap pa din yan). sa point na steady ang ilaw sa Power LED masasabi mong narereproduce pa ng tama yung audio. ;)

yeah I agree, kaya talagang importante sa
audio ang magandang power supply.
usually sa mga design dito ng mga high end na
audio ay power supply talaga ang pinag bubuti.   :)

ang lalaki ng bulk capacitor pag high end audio. ;D walang ripple flat na flat ang supply.
