Disassembly & Review Hi Fi Audio Amplifier AK-170, Mini Amplifier

Hi fi Audio Amplifier AK-170
The power amplifier circuit has been widely used in every electronic device that processes sound. Ampifier which means "amplifier" means to amplify sound input. Voice input can come from radio waves, microphones or digital files that are converted into analog signals.
Power amplifiers are built using passive and active electronic components. In ancient times, electronics hobbyists used vacuum tubes or vacuum tubes as the main amplifier component. The drawback is that the power that the vacuum tube can provide is not large. To produce large power, it takes a lot of vacuum tubes that are installed in parallel.
Transistors that developed later allowed greater output power to be produced, but with a smaller Printed Circuit Board (PCB) size. The growing era of the use of Integrated Circuit or IC is increasingly widespread so that it shifts the use of transistors.
One IC that is often used is the TDA IC. In this power amplifier, the IC used is IC TDA 2030.
IC TDA 2030 has a relatively small power but with a fairly reliable sound quality. The input voltage on the IC can be given at 12V so that it can be installed on a car without the help of a boost converter.
Features of TDA 2030
1. Low-frequency class AB amplifiers are best suited for audio amplification
2. Can supply up to 20 Watts as output power
3. Input voltage between 6V to 36V (can be used for car amps)
4. There is thermal and short circuit protection
5. Easy to assemble

It's a 2x8 w amplifier with 1.5 amps max based on a data sheet of the amplifier discribed.

[@rwarendsz]

It's perfect using it just for the tweeters to compensate for the missing highs in the Bose wave radio but has purchased a suitable power supply the sound is clean . Will do a spectrum analysis on it late this month to check the S/N ratio and the THD. But until now, the sound is super clear. It all depends on the power supply you put on it. A band power supply will surely affect the sound quality in terms of humming and noise.

hii , i can use it with Jamo S622? 80/130W - 87db - 6 Ω

[@naughtymonkey04]

I just bought one of these to go with 2x20 watt Hitachi speakers and a 12v 2amp power unit. Do you think it will work ok with that set up? Thanks

[@ezzzgaming7635]

Coba bikin tutorial btl di amplifayer model seperti ini mas

[@erickakumafuentes]

tengo 2 bocinas de 50w 6ohms ¿sera que me sirva este amplificador? se supone que da 20w por canal y admite de 4-16ohm o me recomiendas otro amplificador?

[@calicafrankie139]

Pwedi ba sya ma lagyan ng bluetooth module idol

[@markthoel9437]

That tda7057 chip is no where near the 20w per channel that the box claims the amp outputs. I have one and it sounds fine for the price. But dont expect miracles

[@MujikoProject]

yes I totally agree with your opinion, indeed many people will have too many expectations but after you try this power amplifier it is only suitable in small rooms

[@rwarendsz]

It's clean, very, very clean for its price

[@Mateoayala-cu7bg]

Bro el mio se escucha super que bajo

[@wholelottavideo8381]

Do you know if this can be used in bridge mode? It says BTL. Mean anything?

[@Testting1234]

Anyone know? Would be good bridged!

[@Rockzone-kt2kl]

Someone needs to try!

[@ZZshot]

Bridge mode would make this a decent, very cheap mono amp for sub or guitar.

[@bnsf_0001]

se te va quemar por encenderlo sin el discipador puesto / will burn beacuse you are powering it without the heat sink installed since the main IC will overheating

[@MujikoProject]

yes of course because the heatsink is the body of the power amplifier

[@eljerry3048]

How can I put on bridge mode?

[@maxmustermann19203]

hello can this run 120watt 6 ohms full range speakers shopee listing says its 200w+200w maximum output wont this just catch on fire if put that kind of load lmao

[@shane731]

yup

[@joseparra108]

Quiero saber si eso ya llegó aquí a Venezuela

[@victorkustov]

TDA7266SA. P=7 w, THD=10% / PO = 0.1W to 2W THD=1% / All/

[@slybunda]

is this amplifier reliable? as in it wont catch fire? just need something small for use in an arcade cabinet.

[@MujikoProject]

according to my experience after using this power amplifier, this amplifier is only ideal for use on 2 speakers with a size of 4 inches only

[@MujikoProject]

and if you want a simple reliable power amplifier for cars, I suggest using a TDA 3116D2 amplifier, I still use this amplifier for my truck, here is the video link if you want to see it kzbin.info/www/bejne/amrFpYdugpyYsNU

[@joseparra108]

Buenos días quiero saber si aquí en Venezuela puedo conseguir ese aparato gracias

[@MujikoProject]

si, prueba a consultar en ebay Hi Fi Audio amplifier AK - 170

[@addorejes3902]

is this applicable to driver unit crown du100?

[@MujikoProject]

Does the amplifier you have have the same supply voltage as this amplifier? if so then this amplifier can be used

[@sideparting6845]

How loud does this go? Thanks in advance

[@MujikoProject]

This power amplifier is suitable for use in bedrooms

[@MujikoProject]

I tried this power amplifier in the park and the result is that the bass sound is less pronounced

[@sideparting6845]

@@MujikoProject Thank you

[@MujikoProject]

you're welcome, I hope I can help you more about power amplifiers

[@ewan853]

Max buat speakernya brp watt gan?,,,

[@IFADWORLD]

Mau tanya lagi gan, ada yg bilang katanya ampli ini harus pake adaptor 12v 5A biar dpt kemampuan max nya sesuai spesifikasi (2x20W RMS). berarti kalau pakai yg 12v 2A dapat berapa watt RMS?

[@MujikoProject]

Dari pernyataan yang ada buat maka kalau pakai suplai 12V 2A maka kemampuan mini amplifier ini adalah ( 2x8W RMS )

[@sazuahmmed3062]

can i use with lg 200watt subwoofer only?

[@MujikoProject]

Yes you can

[@user-xx1dy4rm7f]

Sir saan makaka bili nang wire na ci connect mo sa cp?

[@shane731]

sa shopee

[@renan3279]

hi bro what is the real power of the amplifier? does he accept Bride?

[@MujikoProject]

the price of this stereo power amplifier is 3.5$

[@mattmacabenta9054]

Sir san kba nakabili ng ganyang speaker..?

[@MujikoProject]

I bought this mini power amplifier in an online shop via Shopee

[@ahmadfahri444]

Itu buat 12+6+6 inch kuat gak bang

[@MujikoProject]

Kurang bagus gan, ini mini power amplifier untuk mobil

[@Myrdil]

hello...puis-je l'utiliser pour mon projet de home-studio?

[@MujikoProject]

Je pense que cet amplificateur est adapté pour une utilisation dans les voitures ou les petites pièces, si vous voulez un meilleur son pour les grandes pièces, je vous suggère d'utiliser cet amplificateur kzbin.info/www/bejne/amrFpYdugpyYsNU

[@Tutoni395]

​@@MujikoProject Hey, do you think it can handle a single 8-inch speaker?

[@MujikoProject]

I think this mini power amplifier is capable of handling 8in speakers, but we have to use a good power supply, for example I use a car

[@reycastillo3940]

May order ako ayaw gumana😢😢😢 Sayang order

[@user-is1nk1cc3i]

walapalang bluetooth

[@MujikoProject]

for this mini power amplifier there is no bluetooth feature

[@letsrockza]

its rubbish

[@MujikoProject]

this mini power amplifier is not rubbish, in the hands of the right people

[@letsrockza]

@@MujikoProject any chance you may have schematic?

[@MujikoProject]

I don't have this mini power amplifier schematic

[@letsrockza]

@@MujikoProject too much emphasis on the middle tones, so i removed the caps responsible, also the tda7297 will double output power with NO change to the circuit - its a direct replacement to 15W / channel, as opposed to 7w/channel
