Title: "Circle with the Line Through It"
Post by: Patrick Tracy on February 06, 2013, 01:51:17 PM
I feel kind of bad doing this, but it's just classic:

Even though my knowledge is limited, it's always good to know that I'm ahead of somebody.....

I'm just glad to have gone through that stage before the internet had videos.

Wow... Some of his other videos are just frustrating to watch! Humorous... But frustrating!

Don't feel bad for the kid, he just going through a circle with a line through it.

You want to see how pathetic it can get, go to his "channel" and listen to some of his original material.......

Not much better are all the 'informed' responses that it is "phase inversion", "phase inverter", "phase reversal button", "phase flip", "phase the signal 180º" and so on.  Of course while PreSonus's manual refers to the button properly in some places as polarity reversal and states it 'reverses' the polarity, it also refers to it as "phase reverse".

"Now I just turned the pad on. I don't know what this does either, we will find out." Well, looking at the Clip light on his M-Audio I think its pretty clear he should've left it on (or, you know, adjusted the gain so it wasn't clipping without the pad.)

This is the first I've ever seen this guy... Don't most people doing product reviews at least LEARN what things do before just blindly saying "Here's a button, it does something. Not sure what. Here's another button, I presume it does something else but I'm not positive, for all I know it could do the same thing as the last button. And here's a button that I think does nothing. I don't hear any difference immediately when pressing it so it probably doesn't do anything. And since the label 80Hz makes absolutely no sense to me it probably won't affect you either."

I'm kind of amazed he hasn't managed to blow anything up by turning on that magical 48V button willy-nilly.

Not necessarily.  There have been some attempts at "product reviews" in that Forum section that are roughly equivalent in cluelessness, albeit sans video.

I'll put it this way, then. People doing a product review should learn about the products and what different options on that product do before doing a review. ;)

I gotta learn to pick my battles I guess.

Thanks for making me waste some of my time.

I thought "Mary had a metal lamb" was especially insightful----------------------------------------------

It explains a lot.  He needs more than a "circle with a line through it" to fix that!

Whenever I come to prosoundweb, I always head to the basement first. Threads like this are why.


I had a professor a while back who explained phase to us as "kinda the direction the waveform starts" and thus waveforms have positive and negative phase. He was a networking prof attempting to explain how a modem works. I guess he was a little out of his element. Almost drew him a unit circle on the test, but decided to just play along.


Question: Something I've wondered, why is the null set symbol used? Is there some sort of link, or is just a standard?

I don't know, but it's also pretty much the same as the symbol for diameter.

It's probably the Greek letter phi.

It's customary in physics and engineering to write the angular frequency of a sine wave with a lowercase Greek omega and the phase with a lowercase Greek phi:

sin(omega*t + phi).

Technically, complex numbers are often used so frequently there are terms like exp[i*(omega*t + phi)] but I digress. As my mathematical physics prof once said, complex analysis is all fun and games until somebody loses an i...

Mathematical physics...that sounds like all sorts of bad things. ;)

Here is a picture. (http://upload.wikimedia.org/wikipedia/commons/5/56/PreSonus_TubePre_%26_Comp16_%28preamp,_compressor%29.jpg) I don't think that the line is vertical enough to be phi.

It looks to me like a globe with a polar axis.
