What's going on,
qsu students.f Welcome to another segment,
of Turntable Tune-Up here with DJ Mas.
Now we're gonna be talking about is doing
a fine calibration,
on your pitch on a techniques 1200.
Now, before we get started, there's a
really important note to this lesson.
We're gonna be taking this platter, on and
Now, it's very, very important that when
this platter is off,
you don't push the start button, if
there's power on the turntable.
This platter is designed with a specific
amount of weight, placed on the spindle,
and if that weight isn't there, then it
will wave itself way too fast, and
you can burn out some components in your
So if it's gonna be easier for you to
remember not to do that,
every time you have this platter off, you
can just go ahead and
unplug your turntable and that'll prevent
it from happening.
But if you're good and you're gonna
remember not to do it,
then it's a lot easier to just leave your
turntable plugged in.
So, I've taken this turntable and I've
purposely uncalibrated the pitch.
So if you watched the last video, that's
telling you how pitch is supposed to work.
You're gonna know that at zero,
this center row of dots is supposed to
appear to be not moving, which it is.
Even though the turntable's outta
calibration, when this wi,
when this light is on, that means your
cord's lock is engaged, so
it's always gonna move at the speed it's
supposed to at zero.
Typically, for the most part.
So, as we go to -3.3 to check the
[COUGH] this bottom row seems like it's
But as you go higher, 3.3, this row was
suppose to stop moving and
you can see that it's still going at a
And as you go to positive six, you can see
that the top row is
supposed to be stopped, but it's going way
What this means is, is that we're out of
we need to do a fine adjust.
So the first thing you're gonna wanna do,
is, set your pitch fader,
to the positive six or bottom six and
leave it there, right?
Then we're going to stop the deck.
Turn the power off, and we're gonna remove
Now if you're having trouble getting this
You can take a screw driver with a rubber
tap on the spindle, as you pull up on it,
and it'll pop right up.
Now, you guys,
are going to have a black dust cover here,
that's held on by five screws.
So, go ahead and remove those screws.
They're Phillips screws.
Pull the dust cover off and set it to the
And today what we're gonna be looking at
on the circuit board,
is this top right potentiometer.
Now it's not always blue.
Sometimes it's all metal.
But it's the one that's on the top right.
And you can tell because it has, a
Phillips, screw point.
So what we're gonna, do is, we already set
it to plus six and turned it off.
Now what we need to do is, without the
dust cover on, put the platter back on.
And Panasonic designed it to be this way,
to where you can access that little
Through the hole in the platter, right?
So, we're gonna go ahead and power on the
deck, leave it at plus six, turn it on,
and we're gonna notice or note how fast
the top row of dots appears to be moving.
So, pay attention to the speed of it, then
we're gonna stop the deck, and
you can leave power on here.
And kinda access, this little hole and
that potentiometer, just a little bit, to
see if it,
if it made the problem better or if it
started to make it worse.
And that's gonna tell you which direction
you need to be turning that potentiometer.
You can either turn it clockwise or
Now it looks like it's slowed down just a
So it seems that clockwise was the right
direction to go.
So, it's not perfectly stopped yet, so
we're gonna stop it, tweak it.
And check it again.
Now it's a lot better, it's almost
You can see it's going a lot slower.
We're gonna stop it, tweak it and
just do this as many times as necessary,
until we get this result.
Now we're at positive six, on the pitch
you can see that the top row of dots, has
appeared to stop moving.
Now you're back on you're fine
calibration, where you need to be.
And you can see that at 3.3.
And negative 3.3, good to go.
Now what you’re gonna wanna do, set it at
Stop your deck.
Power off, pull the platter off.
Reattach your dust cover.
There's only one way that it'll sit in
because of the two indentations up here.
So you're gonna notice which way to turn
it when you set it down.
And we're gonna put our five screws back
Make sure that they're tight and that none
of them are sticking up.
Otherwise you're gonna slow down your
your, your pitch will kind of be out of
whack, so make sure that you tighten them
down without overtweaking them, because
you don't wanna strip those screws out.
So just make sure to tighten snug.
Make sure everything is pressed down firm,
and then we're gonna put our platter back
on, and one last time we're gonna turn the
deck on and
check all four ranges of the pitch.
Make sure that we're good to go and
we don't have to go back in there and
That's how you do a fine calibration on
your pitch, on Technics 1200.
Do you guys have any questions?
Once again, please go to the ask Qbert
section on the forums, on QSU.
You guys can find the turntable tune up
And you can direct your questions there.
When I see them, I answer them.
So, that's it.
