Ladies and gentlemen, and you too, Johnny, I'd like to call your attention to the grounded input wiring scheme for accomplishing true-bypass with a mechanical switch:. Dig it! By simply changing the way our switches are connected, we can eliminate the need for that pull-down resistor on the input coupling capacitor!
Hot damn! We just saved us a part, Cletus! Lets have a look at how this scheme works, shall we? When the system is in the bypass state shown abovethe circuit's input is only connected low potential which should be a stable 0VDC in most effects pedals through a coupling capacitor and thus the circuit doesn't really process any signal, except whatever may be lurking on low potential.
The output jack is directly connected to the input jack, and the circuit's output just loiters. DC offset is reduced not nulled! Simple, elegant and effective. AND we nulled out that first pull-down resistor. Close Links - Joachim Gies & Sound/Body/Cells - Shimmering (CD double-whammy! When the system is in the effect state, low potential is removed from the circuit's input and replaced with whatever is on the input jack. The output jack is no longer connected to the input jack, but instead connected to the output of the effect circuit, and BOOYAH!
We have our effect circuit. Slick, eh? So we've saved one of our unicorns, and we're doing a great job reducing DC bleed by giving any DC offset on the input coupling capacitor somewhere to go low potential in this example and by employing a unicorn pull-down resistor on our output coupling capacitor.
Now we've got a nice, pretty quiet bypass scheme. This one is so popular, you'll find it Album) the majority of "boutique" pedals, and many independent manufacturers using true-bypass as their bypass scheme! But, it could still be better. After all, we've only talked about one source Close Links - Joachim Gies & Sound/Body/Cells - Shimmering (CD switch pop. The one everyone thinks about: DC offset, or DC bleed, and its kryptonite: the pull-down resistor.
Would you believe me if I told you that part of that pop you hear is coming from somewhere other than DC offset? You probably would, and if you did say yes, you should really be proud.
Although it seems instantaneous, when you step on that foot-switch and the contacts move from one position into the next, they bounce around for a period of time. As the contacts are bouncing, they are actually not connected to anything, which is a terrible byproduct of such a system but is ultimately what we must give to take mechanical switching.
This might not seem like a big deal, but whenever a conductor is left "floating" or un-connected to any intentional potential hey, it rhymes too! That's because it effectively is. That means that conductor picks up all kinds of stray energy and an alternate potential is established between the conductor switch rocker in this case and its contact.
But this is a little different for a number of reasons. The first being we simply cannot include a unicorn pull-down resistor that connects and disconnects when needed that just doesn't exist, even in the realm of unicorns. The second being the bouncing action that happens when the switch contacts settle into position. The zen of switching, if you will.
And shit, even if you won't. Dig the last diagram for this edition of Straight Jive and perhaps it'll begin to come into focus:. But I though we just got rid of one resistor!? We did. And now we're adding two more. To cancel repeat play, press the repeat button 8 several times to change the repeat play mode to OFF. The track currently being played is played repeatedly.

You can purposefully situate the microphone closer to the sound source and then use equalization to then reduce the increased bass response.
This then serves to protect your sound from bass bouncing around a poor acoustic environment, since any unintended bass sounds approaching the mic, even those rumbling up the mic stand, will already be decreased in volume and then will be EQ'd even lower.
So not only do you defend from stray bass sounds, but you can reduce the handling noise of a vocalist with a hand-held microphone, someone kicking a mic stand by accident or when moving one, and even any bass oriented feedback issues that might occur. Take care when recording electric guitar. The E-string can create a big boom around 80 Hz. The same goes for acoustic guitar with the added possibility of creating a complete mess by placing the mic too close to the sound hole.
For bass guitar, kick drum, and other bass instruments it can be a welcomed effect but only at the risk of harming the intelligibility of the sound by drowning out the upper harmonics. With vocals, you can go too far and harm the intelligibility of the speaker's enunciation as well.
The microphone proximity effect exhibits the most strength on Figure-8 pickup pattern microphones, followed by the most common cardioid pickup pattern.
It's safe to say that most people are using cardioid mics, so be careful. If you want to avoid having this effect occur at all then you should use an omnidirectional microphone, but not one where you're allowed to select that option from many other directionality choices.
These multi-pattern microphones will still exhibit some of the effect even on a non-cardioid pickup pattern, albeit at smaller amounts associated with that pickup pattern. Dodge it altogether with an omnidirectional mic or make it the most pronounced by using a cardioid most common or figure-8 mic. It's a great tool for many types of professional vocal jobs, especially in rap and radio broadcasting. It can sabotage your recordings if you aren't aware of the cumulative effect of bass build-up.
It's subtle and will sneak up on you, and while equalization can salvage your recordings to a degree, it's not without sacrifice. The goal is always to "get it right at the source.
Maintain at least 12 inches of distance between your source and your microphone unless you specifically intend to draw upon the bass response of tight proximity. To put it in the simplest terms Close Links - Joachim Gies & Sound/Body/Cells - Shimmering (CD, if you're aware of the microphone proximity effect, you can use it to great Album) in your audio productions, especially in talk radio, podcasting, and radio DJing.

Thread starter bmillar Start date Mar 15, Joined Dec 9, Posts 8 Likes For at least 10 years I have played my music from lossless rips on the PC through a digital integrated amp, fed into the Stax.
I used to think it sounded pretty darn good. A few days ago just for the helluv it I connected my old Sony CD carousel directly to the SRM-I and I was shocked at the huge improvement in clarity and soundstage.
Ever since, I have been feeding. This is really bugging me. I really enjoy the convenience of playing my music from the PC as software makes it so much easier to find recordings, keep notes, remember where I stopped listening, etc. My PC-based collection file library is also very large.
Any suggestions for an improved PC or digital-player solution that may bring with it the same clarity, quality and soundstage I am getting from my CD player? NA Blur Headphoneus Supremus.
