Let's talk about how to get set up to take your first
measurement in Smaart8. When you open up Smaart for the first time you see a
screen like this and you might
think, "Okay, what do I do now?" There's nothing over here. None of this stuff is
here. First you need to set your i/o settings in your signal generator.
That's under IO config or option a and first just select which
input and output devices you want to use okay so here I only have checked this
audio interface that I'm using same thing in the outputs okay uncheck
everything else you don't have to worry about it down here you want to give some
friendly names to these inputs keep in mind that if you hit tab it's gonna
revert to its previous setting if you want to change this you hit return okay
and that'll take you down to the next one
in this case I'm using input two from our reference loop and then I have these
two microphones in inputs three and four and you can also change the names of
your outputs but I'm really usually only using one so it doesn't really matter it
outputs one to four next we want to head over to the measurement config and here
you might give this a name of whatever the location is that you're working at
today and then if you double click on each of these names you can get into
settings for them this might be a measurement that I'm calling this
microphone name I want to switch back and forth between seeing a measurement
of the same speaker with my EMF 7150 and with my NV 3000 el in another case you
might be switching back and forth between different speakers or different
device under test okay so you want to have a descriptive name here for
whatever this transfer function is going to be a simple way to do this if you're
using multiple microphones and they're all the same microphone would be to just
call them a B C and D and if you want to get really fancy like Merlin Van Dien
you have a B C and D and you have microphone XLR cables that are actually
the same color as these colors I've given the transfer functions here these
are all standard settings here besides the name and the color and then I just
changed the input settings here so measurement signal is my emx 7150
reference signal is my reference loop okay and so I would go now and do that
for each of these each of these inputs that I'm using in this case I'm only
using two okay the last thing you need to do is set up the signal generator in
this this is just the default settings I just want to make sure that I have the
right output selected here and these are settings that I recommend you just open
and quickly verify every time you open your audio analyzer if you don't have a
Y cable so that you can just loop straight out of an output to an input
and you don't have any other way to duplicate that output that's where you
can use the ox here so you might set your ox to output two that way output 1
and output 2 are sending out the exact same thing so you have a duplicate so
then you can head over to spectrum view and you could hit play on these
measurements here that we just set up and you should see some activity down
here okay sometimes these are way too low like they are right now because I
have the preamps turned all the way down and you won't see anything if that's the
case then you need to hit the arrow keys and scroll down and then we can actually
see what's going on here and we still don't we see this pink one but we still
don't see this blue one and that's because it's behind these I have these
the way I would set it up right now is that it's filled here to make it really
easy to see but if I hit the z key that will cycle through which one is in front
okay and you can see them switching back and forth here I guess I could also
switch it here like that just click on these okay so if you don't see your
measurement in spectrum view for some reason and you have hit play on both of
them and you see level here and the input bars here then they may just be
covered up or they may be down too far so arrow keys will get you down there
and then the Z key will cycle through which ones on top and if you want to go
back to the default display click out here okay and then you can head over to
the transfer view which is either the T key or by clicking transfer here and you
should be ready to go on that these two transfer functions that we just set up
that's all you really need to get started now the next question once you
have actually taken a measurement is going to be what do all these squiggly
lines mean and that's what we're going to be getting into in future videos is
how to verify that we actually have good data so I'll see you then
