      a good dac and amp is nice but prices like 400 dollar are unnecessary and retarded. with that said I have to say onboard motherboard audio is most times, total crap.

    • @bernardlim2888
      @bernardlim2888 10 років тому +1

      Lan Party Hosting I would agree that those Audiophool Grade DAC and amplifier are total waste of money. But I don't know what 'crap' a onboard motherboard audio would be, since they sound pretty decent to me, as long they don't sound like a $10 radio speaker.
      Most modern computer have decent onboard sound,even my 2yrs old laptop do support 24bit/192khz sampling rate. What you need more for a 2 channel Stereo sound?

    • @DantalionNl
      @DantalionNl 10 років тому +9

      Bernard Lim its not about the bit and sampling rate, most times the dc to dc converting power supply on your motherboard to power your cpu generates noise which gets coupled into the audio mixer making it sound noisy. Sometimes the microfon signal even gets coupled into the speaker signal or vice versa. meaning that you can hear yourself talk, our your friends hear themselfs / your music. This happens most commonly on cheap motherboard brands like asrock and aopen are worst in my expierence.

    • @bernardlim2888
      @bernardlim2888 10 років тому +1

      Lan Party Hosting For your case it's not the Dc-Dc supply problem.
      you can try goto windows control panel > Microphone properties -- Uncheck "Listen to this device" that's a feedback feature when you have MIC plug in. If not a Noise-Cancelling Headset would solve your problem.

    I'm at 8:38 and trying to figure out how the source impedance for the S (assuming source on bottom, drain on top for this JFET) is lower than the source impedance on the drain. We're talking about from GND and VCC, right? I'm definitely missing something here.
    EDIT: The only thing I can figure so far is that this is actually a common-source JFET amplifier with the capacitor shunting the low-side resistor there to ground. Or, arguably he mentions there is more capacitance gate to source than gate to drain(later). That could definitely unbalance it, guess I assumed it wasn't that big of a difference at the frequencies we're at. And he seemed to act like it wasn't the same thing because they were separated by time he got to it.

    I guess that this is also how the twisted pair cables work in an internet LAN cable by also using the instrumentation amp or some similar principle?

      Ethernet, ironically, uses transformers. At the frequencies that ethernet runs at they're cheap and small. And the isolation is pretty nice to have. They look a lot like a black DIP chip on a NIC.

    Are you sure you have to connect shielding at both sides of the twisted cable? I heard it's not good.

    • @chrisbauer1925
      @chrisbauer1925 4 роки тому +2

      For mic cables, yes. The connection of the shield to the mic chassis helps shield the mics circuitry from noise. It is sometimes recommended that line level interconnects have the shield connected only at one end to break ground loops. This is likely what you are referring to.

  • @baroque_engineer
    @baroque_engineer 6 років тому

    Does the circuit at 9:50 have some name by which I can google it? There's one thing that I can not understand about it. Okay, we have the collector voltage fixed, good. To be able to work in the linear region, transistors need some voltage headroom between collector and emitter (determined by base bias voltage). Well, by looking at the circuit, one can deduce that this is provided by voltage drop on the base resistors, so collector-to-emitter headroom voltage becomes
    Vce = Ibase*Rbase + Vbe
    From this, it is natural to expect that when the AC amplitude of the input (base) voltage exceeds this value, we must hit the collector voltage (fixed by zener diode) and the waveform should become distorted. I.e., it seems that the maximum input/drive amplitude is set with base resistor and transistor beta.
    But SPICE simulation shows that this is not the case! When the input voltage amplitude exceeds base resistor drop, the DC offset at emitter magically shifts to accomodate any AC amplitude, and the real limit is
    V_ac_max = Vphantom/2
    And no limiting at all (until the signal hits the rails, of course)! How this is possible?
    Moreover, it can be seen that when AC input exceeds the above mentioned limit (Vbe determined by base resistor), the voltage on a zener diode actually dips to accomodate the peaks. So, in a sense, AC amplitude limit is actually defined by base resistor voltage drop if we want to have stable power to our curcuit, but not in an expected way.
    Actually, this can be fixed by adding a separate zener diode for the base resistors. I.e., if we disconnect base resistors from the collectors and connect them to a separate zener diode having a greater voltage than the collector zener diode, we'll fix the common mode voltage at one level and collector voltage at the other, providing defined headroom for a signal and stable supply voltage at collectors.

    Dear friends... Basic question.... I have a Korg Pa3x keyboard and I want to use a head worn mid-priced microphone so that I can sing with my hands free whilst playing. Is there any specific microphone that I ought to look for if I wish to just directly plug the 3-pin XLR mic wire into the back of the keyboard without opting for wireless receivers and so on. Also don't know if a wireless receiver set-up could be connected directly to the keyboard or not? The Keyboard has got its own Speakers amplification interface and vocal processor built-in. Many Thanks in advance Raddis from UK

    • @nelumbonucifera7537
      @nelumbonucifera7537 10 років тому

      Not really. Yours is a USB mic, not an analog mic. It solely draws power from the USB port for a fixed-gain preamp and built-in ADC. Most likely you have a driver or software issue. It is faintly possible that your USB host cannot source enough current for the preamp (in which case, try a powered USB hub).
      edit: apparently a common problem with that mic. Poor design.

      Hopefully there is more, it is one of the areas where there really isn't much information available beyond overgeneralized things, especially when it comes to mic design. Compared to other industries, many microphone companies are more tight-lipped about about the inner workings.

      I think people who watch EEV blog are a little more interested in substance than a quick overview. I for one am rather happy with knowing more about microphones than "they turn sound into electricity!!!
      Now i want more about FPGA's

      Don't mind the naysayers. I've been enjoying these. More interviews and whiteboard "design principles" videos are welcome.

      Here is an absolute expert presenting his incredibly deep understanding of analog electronics. And better yet: He's doing it for free! I'm sorry to say it, but everyone who is complaining about this has to learn one or two lessons about life yet..."Undank ist der Welten Lohn".

    Your English style is odd. Its not American nor British.
    Like the circuit, just the same.

    Ok so how do you connect a phantom powered microphone into your soundboard that's all I wanted to know what a crock of yak dung are you talking about.

      Why not just watch some other video instead of insulting? Just because you don't feel you need the information here or don't understand it, doesn't mean this video doesn't have value to other people. Insulting it is just plain dumb.

      the title of the video is How Phantom Power Works not How to plug Phantom Power Mic to a Soundcard that's the crock why.

    I dont know how good are you on designing but definelty on drawing....
    I mean in left side you stubborn continue squeezzing components and also telling its gonna be hard to fit instead redrawing the schematic so they can fit
