wala me alam sa mga tone control

hintay nlang sa iba..

pwede yan tone stack mo kaso dami losses at di stable Zout everytime pihit ka ng pot. I recommend at least a Baxandall with nfb. madali lang yun sir, basa ka lang sa net or ask here.

Designed by Grommes, tama si sir Jojo dami losses, kung twagin ito noon namin "loser type"

Yund design ni Baxandall mas favor ako sa solid state tone controls. you can also try DC controlled like yun sa alexan, bagay sa mga mahilig sa shimmering highs at punchy (& boomy) lows

pahingi po sir yung meron kayo yung madali lang para sa beginners na katulad ko..

hi, it looks like that the tone control above is Gromme's Tone Control circuit. You got it Sir Efren, it is Loser type.

Mayroon mga series ng Tone Control transistorized at sak IC doon sa book ni M. Pagarigan at S. Bandi, Practical Electronics series IV they are Baxandall type, particulary on page 47, a Tone Control with Bass, Mid and Treble, included circuit, pcb layout at saka assembly instruction. Personally, the performance is good which I believe with +/-20dB boost/cut. Having a mid control makes me more enjoy the Bass and Treble response with Rock music when the mid frequencies is attenuated.

Madali naman gawin ang kanyang mga circuit, ang matindi nga lang ay ang integration sa power amplifier in which you need to be very careful lalu na sa power supply sharing, split power supply. Sa mga circuit na binuo ko, separate ang power supply ng Tone Control.

@louiex, I will get back to you on this once I got the info, malayo ako sa bahay ngayon.

OT:
I have some digital Tone control with at least +/-14 dB bass/cut - they are of modern type with added features like Surround effect, 3D sound, some included SRS, TruBass, etc. The latest one is the DR100W_EQ (Equalizer Module) comes with Tone Control with preset Equalizer as Rock, Pop, Jazz, Classics, 3D Sound, Turbo Bass and digital Volume Control. All of these tone control requires software knowledge to program them since they are digitally controlled type, they won't function without software.

salamat sir dandy... kaso dun sa sinabi mong digital di na kaya ng power ko ala ako kamuwang muwang sa mundo ng programming sir... 60 hours lang kasi ang pag aaral ko sa training center kulang na kulang ako sa kaalaman kahit nga sa basic electronics... nadagdgan lang dito sa elab kakabasa....

GOOD evening po sa lahat.. ask ko lang po sana mga master kung makaka affect po ba sa circuit yong wattage ng resistor?? kasi po nakalagay sa component eh 22k ohm /0.6 watt para sa r1 and r3 sa schematic ng TDA 2050.

kya lang kagagaling ko lang kanina sa electronic shop dito sa amin ,, bumili na ako ng mga components na gagamitin ko sa pagbuild.. wala ako nahanap na 0.6 watt.. kya binili ko 22k ohm pero 1/2 watts xia or 0.75.

ang tanung ko po kung pwede na kaya un gamitin sa amps?

tsaka meron po ba pwede pampalit sa capacitor na ang value ay 0.47uf??

kasi wala po ako mahanap dito sa area namin eh.. from bikol po pala ako..

salamat po mga masters.. sana po may sumagot po sa akin kasi need ko na talaga mabuo ito amps ko eh!! project kasi namin..

tska nga pala nagpapasalamat din ako ng marami kay master BABY AMPLI !!! plus 10 ka sa akin master!!

ikaw ang lagi sumasagot sa mga pm ko sau.. at kay sir nothing poh maraming salamat din po sir...

efren · « **Reply #50 on:** August 05, 2012, 08:15:51 PM »

walang problema sa wattage, kahit surface mount pwede mo gamitin dyan, ang importante since gain & feedback ang task nyan, kailangan close tolerance, 5% is acceptable...

By the way, never heard of .6W resistor, common fraction wattage values as far as resistor values are concerned:
1/8w = 0.125w
1/4w = 0.25w
1/2w = 0.5w
3/4w = 0.75W
better check the specsheet as per manufacturer, wag basta basta pupulot ng schematic sa net, sa wattage palang ng resistor pinahihirapan ka na, lalo na kaya ang final outcome nyan...

at ang lagi ko pinagdidiinan dito, ang gainclones o IC amp, maselan sa layout ng grounding, this will make or break your project... better to familiarize yourself further with gainclones to save you further headaches in the future.

haist.,, marami salamat po sir efren sa pagreply,, di pwede na po pla yong nabili ko resistor??

nice,, ang problem ko na lang ngayon ai ung capacitor na .47 and 0.1 uf!!! haizt wala dito sa amin nyan eh!!!

400V kc...

anu po ba pwede pampalit dito??

400V ano yan de-tubo para lagyan mo ng ganyang voltage rating, kahit 50V pwede dyan

hmmmm nakapagdududa ah, post mo nga yung link ng schematic....

anu daw! 400volts! baka mylar o ceramic yan pero bakit 400 volts hindi naman high voltage yung project ah

mga master,, eto po ung link.. and jan ko din po dinownload ung component list.. pakicheck naman po.. tnx po

lagyan nyo na lang po ng http:// sa unahan ng site kasi bawal dito magpost ng external links eh.. tnx
po master

yung 0.47uf is 474, 0.1uf is 104. yung code ibigay mo sa nagbebenta dahil hindi nila alam magdecode these caps are mylar, 100v rating is ok

kaya naman pala, eh puro premium at boutique parts ang specified ng author, kung susundin mo yan, makakabili ka ng dalawang Sakura high power amp

tama sis kalimitan hindi nila alam yung code kaya pag hindi mu rin alam lagot na uhok agad ang circuit..

JAYRAM · « **Reply #59 on:** August 06, 2012, 09:13:49 PM »

sir efren,, anu po ba mga pwede ipalit ko componenets dun??

specially ung 1uf na capacitor..

kasi wala ako mahanap na 1 micro farad eh!!! polyprolyne cap kasi nakalagay dun sa list of components..,,

pwede ko po ba un palitan ng elctrolytic capacitor na ang value ay 1uf din??
