Let's take a look at module 4 of Pro Audio Workshop:
Seeing Sound. Everyone wants to know how to EQ. This lesson is all about
EQ and listening. As we get into the first lesson of this module:
The goal is sound system tuning, this is going to talk about the difference
between tuning and toning, right, so kind of the science and the art you've got
the mixing board over here where we're doing all the art and then we've got the
system processor over here and speaker position aim and system design over here
and then I give you some examples of target curves we talked about that the
second lesson in module four is about when to use EQ so how do I know if the
problem I'm experiencing can even be solved by EQ so we talked about that
here and just some general guidelines for what's actually possible with EQ
how to set EQ filters this is a surprisingly simple lesson and hopefully
will be a breath of fresh air for people who were really worried about this I
have a pretty simple process that I teach alright now we're going to get
into the EQ order of operations this is where we start learning about combining
speaker by speaker until we get an entire system so we always start with
single systems add things to it and then move kind of along the line of priority
until we get the whole thing running together so just give you an example
let's say that you have two mains and the front fill so you're going to start
with one main you're going to listen to that EQ that then you're going to turn
the second one on unique you those together and then you're going to turn
the front fill on EQ those together so we have a whole process here for
deciding which speakers to EQ in what order and this just talks about how to
EQ that first single speaker and how to decide which one to start with
next we moved the speaker to speaker so once we've eq'd one speaker now we're
going to turn on another one together and even if we stand right in front of
that speaker that second speaker on with it is generally going to affect it
somehow right even if it's not pointed in the same direction so we're going to
look at what measurement microphone positions do we need to use and what is
the order of operations here so that we can be efficient with our EQ but also
not create a monarchy so one of the biggest problems with EQ is when people
just put a microphone in front of house and say okay microphone on entire system
on EQ filters done when what we really need is generally a little bit more
specific approach where the speaker here for this part of the audience is going
to need a certain kind of EQ and maybe this different speaker from a different
manufacturer for a different part of the audience in a different part of the room
is going to need a slightly different EQ and then we're also going to need to
look at those two responses together where they cross over the acoustic
crossover point somewhere in the room once we've done a single speaker and the
speaker to speaker then we start to look at array to array and array to room so
you can see it just kind of gets bigger and bigger and what I really like about
this process is it helps us really reduce the amount of chaos we have to
deal with right so now we have a system for looking at this stuff and we're not
trying to observe and fix twenty million problems from 20 million sources all at
once no we're looking at one source at a time combining those making those work
and moving on to larger subsystems that's the end of module four so we made
it all the way through EQ and listening and in the next video I want to look at
module 5 which is crossover alignment
sound design
