How do you measure an EQ plus a full-range speaker and what does
that look like in the room? So at this point we've measured a microphone cable
and EQ, a full-range speaker in the room and a sub in the room. Now let's put the
EQ and the full range speaker together and just see what that looks like
so as we're taking small steps forward and just practicing at home I feel like
this is the next logical step we measured just the speaker by itself
we put the speaker in a bunch of different locations we move the
microphone all around the room and we sort of just observed the measurement to
see what sort of trends we could see what can we learn from just moving
things around and looking at the graph and now we're getting better and better
at just reading the data and seeing what's there and seeing how the data
correlates to where things are in the room so in this next step we'll just
connect the EQ and see what that looks like so just to review the way I have
this routed in the x32 is that I have the output going to my speaker coming
from matrix one and then I have the reference output coming out of ox six
but it's pre EQ okay that's why it's slightly red here and expert two calls
that input low cut we should be able to turn this on and this should look pretty
much like the speaker we measured earlier except now it's in a slightly
different location you can see the speaker is lower it's just on top of the
sub and then I have the microphone over here there's an obstruction in the way
because there's a little light back here and there's probably going to be some
reflections off of the wall
great so there's my speaker in my room and obviously when I talk it messes up
the measurement but what I can start doing now is just opening up my cue I
can pull it down here
you and I can just start adding in some
filters
to see the results on the amplitude okay what does this shape on the EQ look like
an actual speaker in the room
you
okay and after you play around with that a little bit then you might want to
switch around to just looking at the face trace so I'll put the face trace up
here and go back to the EQ reset this now let's see what happens
look interesting it changes around a little bit when I add a filter in and it
gets messed up when I start talking
you okay so it seems to add some delay and
change the phase around that frequency whenever I move these filters around so
again these are just things to observe as you're playing around with this and
then you might want to rearrange your windows so that you can kind of look at
all of this interact at the same time see the amplitude down here I'll put it
back up like this amplitude up here phase down here and as we play around
with this we kind of start getting used to like these gross squiggly weird lines
right I might take this away if I don't need it right now and have even more
real estate
all right so that is measuring a speaker with an EQ in a room and in the next
video I want to talk about how to identify a comb filter because you may
have noticed that there's some a lot of piece and valleys up here and we want to
think about what we actually have control over with our EQ
