D6s so với ZD3 thì như thế nào hả bạn. Nếu chọn amp thì V3, V3 mono và ZA3 thì dùng cái nào hay hơn b tư vấn giúp mình nhé

For me it works perfect, at the beginning just need a few steps to set it up correctly. Windows10+Cubase ..

Class D has the problem that the distortion above 6khz increases too much if the volume increases. With the AB class it is possible to easily obtain a distortion of less than 0.1% up to 70% of the maximum power. With class D, distortion above 10khz increases terribly over 25% of the maximum power. Using a more powerful power supply, the phenomenon is reduced but does not disappear. Fortunately, it is rare to exceed 10 watts to listen to home. TPA3255 has a particular feedback system that reduces some defects in class D, so you can expect 10 watts clean at 20khz (0.1% distortion) but, increasing the volume, it is easy to exceed 0.3% to 20khz. It is true that a standard human ear does not perceive the distortion of over 12khz, but a young musician could understand that something is wrong.

Bạn có thể hướng dẫn lại con 3255 mod mono không. Hoặc 3251 mod mono càng tốt bạn. Tìm mãi ko có mạch mono con chip này.

Hi Trung QN :) What temperature difference did you notice between the original and your mod please? Thank you in advance for your answer.

How to increase the power itself ? Because I tested my Aiyima A07 using watt meter and it only draws most of the time at normal listening volume, 8 watt from wall socket, using 48v 7.3A Meanwell LRS350 Power Supply. My other bigger amp can draw 40 watt and the punch to my 400 watt each speaker set is powerful, while this Aiyima A07 cant provide the same punch to the same speaker. I know the real measurement is much more complex than that, but it works, bigger power draw from wall socket will provide stronger bass punch. Usually , ppl change the capacitor, I notice my bigger amp has 4x 2200uF capacitor, while this Aiyima a07 only has 2x1000uF, is changing the Electrolyte Capacitor (ElCo) going to provide more punch to the bass ? Because I read elco is like the power silo that provide the juice to deliver more bass, so bigger is ofc better. If I change it to like 2200 or 4700 uF, will it improve bass ? What else needs to be changed ?

Chất âm ăn dc mấy mạch việt nan nt trên shopee k bạn

replace opamps

coilcraft is very nice. as i remember texas instruments are using them in their demo board. würth also has a high quality inductor at the same level of quality. pimping the output filter with lower inner resistance should give you better dynamic control and less distortion at higher output power. very good choice. regarding changing caps, i always look at the panasonic low esr types ike fc or fm series.

Tôi kỳ vọng vào KA11 nhưng nó không kết nối với mic để sử dụng các chức năng cơ bản của đàm thoại, chất âm khi nghe cùng KZ ZSX, EDX củng tốt với iPhone. Tôi thích chất âm của ddhifi tc135i hơn.

No any details. Just for views

Mình mua cái này rồi, dùng rất chi là ổn, chỉ là không có driver mà thôi, tải driver asioall về dùng ok.

Xin giá

What is that clicking sound?

Whats the program?

not reconize problem: 1. issue at usb port or cable 2. no correct driver for the chip💀 3. the cable only send power

Vậy theo bạn chiếc KA11 này có đáng mua ko?

I'm thinking of buying this over for myself. Currently I run um2 and it's not enough for my used dt 770 pro 80ohm at all :( Do you think this u1 is gonna be ok for me? :3

😂😢😮😂😮😮😂 estou passando por isso também kkkkk

Was impossible for me to make it work on a Windows 8. Even trying manually with many drivers for sound included on windows. I writed to support and they have to answer me in few days but probably there was no solution and I will take it back to China

bro how change stereo to mono plz help 🙂

is the quality of sound nice??

45v và 48v thì sao bạn

What is your operating system? I have exactly the same card. It won't start on Windows 8.1...

Dòng D10 này theo bác dùng oke không ? M nghe nhạc điện tử nhiều

ok since this is the only TPA3255 /PFFB video on YT I leave this here. No offence ok. Nice job. But as TI's own figures show, the result is not worth the effort. Yes, it makes the damping factor higher. But the absolute numbers are so low and there is like 0.00X redection in distortion in higher frequencies. And gain is less. Even if TI issued this PFFB paper, I don't think they are that much convinced themself. Think the 3255 was designed from the start with the integrated pre-filter. And it's just a fine chip as it is, for almost no money. For something really noticable better get Hypex or Purifi.

Bu devrelerin en iyisi hangisi ses olarak.

Try to conneto tro pc with another usb cable, directly to usb with no extender.
