It's also fun to play with when you're sitting in front of the computer and you've had too much caffeine .

I found this graph from an old F-2B data sheet:

Dad says it's the same for the F-1X.

Mica-

While I would never doubt your father in the world of audio electronics, that just doesn't look right at all. It just doesn't make sense that the 10-10-10 curve would fall below the 3-10-3 curve all the way across. Or, is the graph only to represent the shape of the curves and not their positions relative to each other? If that's the case, then it makes perfect sense.

I plugged the same numbers into the program and came up with the following. I tried to scale my graph to match Mica's. The shapes of the curves are similar to those in Mica's graph. From top to bottom as they start on the left:
10-10-3
10-10-10
3-10-3
0-10-10

Rats! The TSC doesn't have a download for MacIntosh. I'll just have to rely on the good graces of my Windows employing pals in the club. Thanks for the post, Dave, Mica and others.

The graph I provided is on a relative scale. I'm afraid the 0-0-0 is so flat, that there is no signal. Try it on your own F-1X - there is no sound. It would also be interesting to see 0-0-0 from the TSC.

David Houck · « **Reply #36 on:** January 11, 2005, 01:28:24 PM »

Mica; 0-0-0 is in the first graph. You can't see it because, as you expected, it's a straight line across the very bottom of the graph.

Here is:
0-0-10
0-0-5
0-0-3
0-0-1

Okay, I have a semantic/stupid question...

Using the TSC set for Alembic.
Set Bass-5
Set Treble-5
Now, As you slide Mid from 0 towards 10 the Y value for the mid increases and that Mid dip becomes less of a dip.

So when someone says that increasing the setting on the mids is cutting the mids. What they mean is its reducing the sharpness/depth of this mid dip? Or am I still interpreting this wrong.

cuz, previously, I when I read cutting mids I though it meant lowering mids, but this doesn't look the case at all in the model, I'm playing with.

David Houck · « **Reply #39 on:** January 11, 2005, 03:14:17 PM »

Jeff; I've always associated cutting the mid with decreasing the setting of the mid control; i.e. reducing the mid from 5 to 0 would be a significant cut in the mid range.

thanks Dave,
haha, I gotta stop staring at these slopes...

someone, above had the line.
The mid pot doesn't ad but it cuts less from zero. which although accurate, I have now misinterpreted twice, doh.

The mid pot does increase mids going 0-10...
Its just that you can't push the mid level above the bass or treble level. The most you can is push to flat.

okay, I'm changing my name to TSC_illiterate.

My heads spinning! All's I know is: I like it!

David Houck · « **Reply #42 on:** January 11, 2005, 04:35:45 PM »

Jeff; I think you've got it!

Hollis; me too!

Sorry Jeff,

as a technical moron I had no other way to say it: cuts less from zero. You can not add above zero I mean. Looking at the graphs forinstance I first interpret them as nice pieces of modern art and admire the fluent lines waving on the grid. Scientific interpretation comes in my mind about a week later.

Alembic HAS something with those mids. You will not see frequently electronics with a mid cut/boost. What I remember from previous threads is that it is far common to interpret the higher end and the lower end of the tonal scale. I shoudl say devide the spectrum in two halves and done. When adding a tweaking device for mids the discussion starts from WHAT frequency you want to start hte influence of the pot and where do you want it to stop.
I don't say it right I suppose but I do remember a thread where Mica explained something about that.

Paul the bad one

mrfunkwool · « **Reply #44 on:** January 12, 2005, 05:58:06 AM »

No apologies, necessary, Paul.

Not your fault.
I just read it wrong. It makes sense to me now.
Looking back, I can't think of a simpler way to state it either. I just needed to stumble thru before I could walk.

Glad my ear, interprets sound better than my head!

This has been a great lesson for me.
For whatever reason, I just never caught on how changing one setting alters the other settings.
