amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. The amount of amplification provided by an amplifier is measured by its gain: the ratio of output voltage, current, or power to input. An amplifier is a circuit that has a power gain greater than one.An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are widely used in almost all electronic equipment. Amplifiers can be categorized in different ways. One is by the frequency of the electronic signal being amplified. For example, audio amplifiers amplify signals in the audio (sound) range of less than 20 kHz, RF amplifiers amplify frequencies in the radio frequency range between 20 kHz and 300 GHz, and servo amplifiers and instrumentation amplifiers may work with very low frequencies down to direct current. Amplifiers can also be categorized by their physical placement in the signal chain; a preamplifier may precede other signal processing stages, for example. The first practical electrical device which could amplify was the triode vacuum tube, invented in 1906 by Lee De Forest, which led to the first amplifiers around 1912. Today most amplifiers use transistors.
Hi..I want to make an audio amplifier using my old ATX power supply coz someone do it like this and i want to try to..Can you help me to find an schematic diagram for it so that i can do it on my own..Thank you!👽
Hello po, baka po may nakaka alam ng problema netong amplifier ko di kasi nagana yung Audio Output ng BASS at FRONT LEFT & RIGHT pero nagana naman po ang REAR LEFT & RIGHT at CENTER.
sana po may makatulong salamat!
Ano ba sulit na power amp ngayon? Bumigay na kasi yung 502 ko kaya magu-upgrade na ko from integrated. Mga 15k lang budget ko, tsaka saan legit umorder online?

Mga sir kakadating lng ng order ko na ampli sa lazada issue po ba ito ung pag naka zero volume eh parang my tumutunog sa speaker parang tunog popcorn haha nakakatuwa pero totoo defect kaya ito?
Pa try nmn sa my mga gantong ampli thank you po
patulong naman di kasi ako marunong sa mga WATTS na yan may binili kami amplifier 500WATTS ilang WATTS dapat speaker na bibilhin ? parang may nabasa kasi ako dapat may tamang watts din para di masira . pang videoke sana .
salamat po phc :)
patulong naman po kung panu po gamiting speaker ng tv ang amplifier.. anu pong connector ang kailangan ko pong bilhin or gamitin? wala po kasing sound ung tv.. need speaker para po magkasound. salamat po sa makakatulong
Sira po ang out ng amplifier namin. Yung right spkr A at right spkr B po ang sira. Sinubukan ko na po lahat ng speaker namin na isaksak dyan pero wala talagang tunog. Sa left lang meron. Ano po kaya ang sira nito sa loob? Gusto ko po matuto kung paano ayusin ito. Maraming salamat po sa tutulong...
about po sa amplifier ko.. yung sa channel ng speaker nya yung right side lang po gumagana yung left parang shorted kasi po gargar yung tunog nya. pa help naman po mga master jan
advance salamat
Good day po sa lahat .
Sa may alam jan sa mga sounds system paano po ba malalaman f orig yung amplifier na
Sakura AV-735
Kasi alam namn natin na marami na ang mga fake ngayun so henge nlang po ako nang tolong
Salamat po
