He said following things eagerly in his lecture. I also designed to set 22pF chip capacitors into crystal oscillator. It got much more clear like urban escape. TA is D-class amplifier and it uses PWM, so it would not good to include the noise which frequency is as high as switching one. Further more, it was already converted into DIP package.
This catch phrase is “realizing ritch bass and well spread mediant and treble”. Bass reflex is wrong regarding reproducing the original sound.
making NOS DAC — TDA1543 + CS8414 —
I planned to set chip capacitors which had about 0. I adopted the method of used only a resistor because I wanted to get true sound. Was its reason time lag caused by the differences of the path-length? I regret I’ve not use a flash. Unit sounds based on this enclosure, so if this standard point moves, unit cannot reproduce true sound.
Why it didn’t suit in my case? I asked 2ch liver, brilliant mind in Japanese largest internet discussion board, for instruction and I finally got the solution.
If you use datssheet feedback, the induced voltage of speaker unit which willl be caused by acoustic pressure from outside will come in from line-out and amplifier will compensate including this voltage, so we will be unable to sound true sound. In my case, power amplifier had its own LPF.
I used blue LED as a indication lump. If fatal problem occures, I’ll set LPF. 74hc74wp felt a bit of luxury. It is not good to adopt negative feedback when you want true source sound.

I didn’t feel about speaker position, it was as is dataasheet were really source. It dataeheet be based not on frequency responce but on impulse responce.
When I watch a movie without lamp, it produces a flavor of romantic mood. I thought its difference would be very small. DJ goods — cartridge, record cleaner The bass from the duct of bass reflex is deadlly delayed, so it cannot get enough punch. Its bass might be cut off, so I added 2. I was about to eat them by mistake. I want to try parallel use.
making NOS DAC — TDA + CS —
I’m sorry for my bad English. So I decided to make DAC which would use no negative feedback. Setting a lot of capacitors which had good high frequency characteristic into the power supply legs of IC, OSC and regulators. If BBS doen’t satisfy your needs, give me a mail. Enclosure will 74hd74ap vivrated by sound pressure of speaker unit.

It may dataaheet good to adopt para-using film capacitors in couppling. Para-using of TDA was famous method to improve sounding. We usually adopt fc cut-off frequency of LPF as fs in order to remove aliasing noise.
Frequency response is a responce of sin wave. Speaker unit should be grounded on completely unmoved point. I drilled a small hole.
In his lecture he tought following practical things. Heavy unit can’t immediately responce. So I came to the conclusion that contemporary audio engineering had to be wrong. A lot of recent audio DACs adopt the method of Delta-Sigma converter, so it will have many 74hc774ap actually.
But I heard that it use negative feedback. I believed that it was a nice one. So I chose 74AC If you want a true responce of sound, you should design based on impulse responce.
