Making the Most of Your Mixer
BASIC
If so you might want to build the 
mix around the vocals. This 
means bringing the vocal channel 
up to nominal first (if your level 
setup procedure has been done 
properly this will be a good 
starting point), and then adding 
the other instruments.
What you 
add next will 
depend on 
the type of 
material you 
are working 
with and 
your 
approach to it. If the vocals are 
backed by a piano trio and the 
song is a ballad, for example, you 
might want to bring in the piano 
next and get the vocal/piano 
relationship just right, then bring 
in the bass and drums to support 
the overall sound.
Example2:
Funky R&B Groove
The approach will 
be totally different 
if you’re mixing a 
funky R&B 
number that 
centers on the 
groove. In this case most 
engineers will start with the 
drums, and then add the bass. 
The relationship between the 
drums and bass is extremely 
important to achieve the “drive” or 
groove the music rides on. Pay 
particular attention to how the 
bass works with the kick (bass 
drum).
They should 
almost sound 
like a single 
instrument—
with the kick 
supplying the 
punch and the bass supplying the 
pitch. Once again, there are no 
rules, but these are concepts that 
have been proven to work well.
To EQ or Not to EQ
In general: less is better. There 
are many situations in which you’ll 
need to cut certain frequency 
ranges, but use boost sparingly, 
and with caution. Proper use of 
EQ can eliminate interference 
between instruments in a mix and 
give the overall sound better 
definition. Bad EQ—and most 
commonly bad boost—just 
sounds terrible.
Cut for a Cleaner Mix
For example: cymbals have a lot 
of energy in the mid and low 
frequency ranges that you don’t 
really perceive as musical sound, 
but which can interfere with the 
clarity of other instruments in 
these ranges. You can basically 
turn the low EQ on cymbal 
channels all the way down without 
changing the way they sound in 
the mix. You’ll hear the difference, 
however, in the way the mix 
sounds more “spacious,” and 
instruments in the lower ranges 
will have better definition.

Fundamental: The frequency that determines the basic musical pitch.
The fundamental 
 and harmonic 
 frequency ranges of some 
musical instruments.
Some Frequency Facts
The lowest and highest frequencies than can be heard by the 
human ear are generally considered to be around 20 Hz and 
20,000 Hz, respectively. Average conversation occurs in the 
range from about 300 Hz to about 3,000 Hz. The frequency of a 
standard pitchfork used to tune guitars and other instruments is 
440 Hz (this corresponds to the “A3” key on a piano tuned to 
concert pitch). Double this frequency to 880 Hz and you have a 
pitch one octave higher (i.e. “A4” on the piano keyboard). In the 
same way you can halve the frequency to 220 Hz to produce 
“A2” an octave lower.
The frequencies controlled by the LOW, MID, and HIGH bands 
on this mixer have been specifically selected to provide the most 
“musical” range of adjustment with the widest possible range of 
instruments (100Hz, 2,500 Hz, and 10,000 Hz, respectively).
Harmonics:
Multiples of the fundamental frequency that play a role in 
determining the timbre of the instrument.
