If we sample by over 2f, we will be able to restore avoiding distorted by LPF because fc gets to be much higher than 2f. Please do at your own risk.


Unit sounds based on this enclosure, so if this standard point moves, unit cannot reproduce true sound. It is impossible to make ideal LPF, so we have to use dull one and high frequency component of original signal often becomes distorted by this dullness. For example, used only a resistor, buffer of OpAmp, buffer of vacuum tube, impedance matching circuit of line transformer and so on. I thought its difference would be very small.

I asked 2ch liver, brilliant mind in Japanese largest internet discussion board, for instruction and I finally got the solution.

Braid black and red cables reminds me of poison spider. But I heard that it use negative feedback. Marvelous sound were flown out from a tiny plastic speaker.

N is the sum of noise which is added from 0Hz to For larger image, please click. In addition to this, we can suppress noise component because we can scatter it to the area which is from 0Hz to fs over 2f. Then it got very clear and beautiful. I forefelt it would work well. This is a photo which DAC has beeing sounded with optical input.

I’m sorry for datsaheet bad English. A lot of recent audio DACs adopt the ratasheet of Delta-Sigma converter, so it will have many benefits actually.

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 74hx74ap including this voltage, so we will be unable to sound true sound. They adopt current output, so we can use plurality of them in parallel. I reviewed the wiring of GND, removed re-clock circuit and adjasted potentiometer, but I couldn’t get clear sound. I was about to eat them by mistake.

It was very easy to process acrylic material. And I added MKT 0.

If BBS doen’t satisfy your needs, give me a mail. This removing tool is low pass filter. I’m ashamed of the sight which have been added BG-C as smoothing capacitor. Digital inputs were 2 ways 74hc74al and optical. I’m happy it looks so nice regarding flush.


I drilled a small hole.

I want to try parallel use. It should be based not on frequency responce but on impulse responce. The bass from the duct 74hc47ap bass reflex is deadlly delayed, so it cannot get enough punch. If you have a question or comment, please use BBS. Its bass might be cut off, so I added 2. I liked this because it added beautifulness to the sound.

Was its reason time lag caused by the differences of the path-length? I don’t take any responsibility for the trouble that can occur for this homepage. Bass reflex is wrong regarding reproducing the original sound.

Enclosure will be vivrated by sound pressure of speaker unit. The blank space was to add smoothing capacitors. Avoiding incoming noises from unused digital input, I used relay and would hook up with one-side of digital 74h74ap to DAI.
