nope. its a dual preamp ic.

ito ung sample ng tone control. ang purpose nya ay serve as equalization para maadjust mu ung pitches or frequencies in an audio signal. (Bass, Treble, Volume)

btw ung captain. familiar sa akin yan.




nlalagay yan bandang tone con. na nkaconfigured as low pass filter. kya pabor xa sa bass sound. sikat na sikat yan noon. ^_^

sir ultra salamat po sa tulong natapos ko na rin at gumagana na yung amp ko na an7161 problem ko lng po ay ang paglagay ng captain, alam ko po ang mga combination ng mga caps at resistors na i seseries sa transformer kaso lang ay kung saan ko ito ilalagay iisang c828 lng ang gamit ko na tone control sa bawat channel pede bang maka hinge ng block diagram? dito kasi sa cebu ang mga amp na ganito ay nilalagyan ng switch para ma toggle ang isa hanggang tatlong kumbinasyon ng captain paano po nila ito ginagawa? thanx po in advance Smile

200 watts lng po ung maximum na rating ng output trans.
Pero pwede mong dagdagan ng isa pang transformer.
Ang amperage ng booster amp ay depende sa wattage ng booster, sa akin ok na ang
15 amps na transformer para sa 400 watts na booster Smile

kailangan mo nang capacitor kung kukulangin sa bass ampli mo lagyan mo nalang ng dalawang 10,000uf na caps mas malaki farad mas mabuti, yung mj 2955 is 25 each nung bumili ako last..

sa audio input transformer po bah iconnect ung monocord?
newbies po ako..pkihelp naman..gawa din ako ng ganyan..

tsaka boss, ung sa power amplifier circuit,push pull, kaya po bang mag power output ng 5 W kung 12 V lng ang supply?

idaan mo muna sa small or low amplifier(5W-15W). para hindi kapos ang audio signal pagdating sa booster amplifier mo.

ganito ang gawin mong set-up



sa input ng low amplifier ikakabit ang monocord dahil diyan magsisimula ang audio source mo {FM/AM tuner, walkman, Mp3}

iyang power amplifier na nasa larawan ay ang Booster mo

ang lakas ng booster ay hango din sa output transformer

@ hertz
sir ang kaya ko lng gawin ay 1W Pout,kc nakadepende ang Pout sa source,,d ko pa alam gumawa ng 5W amplifier,wala kc akong design procedure...pwede mo ba ako bgyan ng 5W amp design...12V dc source lng..pang motor...

sna matulungan mo ako.....
