In his lecture he tought following practical things. It cannot be a responce of “sound”.

I regret I’ve not use a flash. I often find DAC kits that adopt 2, 4 or 8 inparallel when I’m roaming the net. Why it didn’t suit in my case? I forefelt it would work well. We shoud prepare unmoved ground.

A lot of recent audio DACs adopt the method of Delta-Sigma converter, so it will have many benefits actually.

You shud use speaker unit as light as possible. I was happy to have closed in true sounding.

datashet In order to suppress switchinig noise of regulator, setting a PI Low-Pass-Filter which is built by 74hc74pa and toroidal core coil. This is excellent for the theme, “I want to make cool audio devices at small cost”. I didn’t feel about speaker position, it was as is it were really source. Bass reflex is wrong regarding reproducing the original sound. It is far from the thought of reproducing the original sound in the first place.

For larger image, please click. This LPF bothers us. I adopted the method of used only a resistor because I wanted to get true sound. I’m sorry for my bad English. I used three TDA 3para.

If fatal problem occures, I’ll set LPF. Speaker is bass reflex type and its unit is 12cm. If you can reproduce the original sound, you will be able to get enough bass edge. For example, used only a resistor, buffer of OpAmp, buffer of vacuum tube, impedance matching circuit of line transformer and so on.

If you use negative 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.

We usually adopt fc cut-off frequency of LPF as fs in order to remove aliasing noise. Braid black and red cables reminds me of poison spider. If BBS doen’t satisfy your needs, give me a mail. Technics turntable — modifying SLMK3 It should be based not on frequency responce but on impulse responce.

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. I also designed to set 22pF chip capacitors into crystal oscillator.

N is the sum of 74hc7ap which is added from 0Hz to I liked this because it added beautifulness to the sound. Marvelous sound were flown out from a tiny plastic speaker.

I planned to set chip capacitors which had about 0. Dataasheet I watch a movie without lamp, it produces a flavor of romantic mood. I reviewed the wiring of GND, removed re-clock circuit and adjasted potentiometer, but I couldn’t get clear sound.
