Making the Most of Your Mixer
You’ve got yourself a mixer and now you’re ready to use it.
Just plug everything in, twiddle the controls, and away you go … right?
Well, if you’ve done this before you won’t have any problems, but if this is the first time you’ve
ever used a mixer you might want to read through this little tutorial and pick up a few basics
that will help you get better performance and make better mixes.
Balanced, Unbalanced—What’s the Difference?
In a word: “noise.” The whole point of balanced lines is noise rejection, and it’s something they’re very good at.
Any length of wire will act as an antenna to pick up the random electromagnetic radiation we’re constantly surrounded by: radio and TV signals as well as spurious electromagnetic noise generated by power lines, motors,
electric appliances, computer monitors, and a variety of other sources. The longer the wire, the more noise it is
likely to pick up. That’s why balanced lines are the best choice for long cable runs. If your “studio” is basically confined to your desktop and all connections are no more than a meter or two in length, then unbalanced lines are
fine—unless you’re surrounded by extremely high levels of electromagnetic noise. Another place balanced lines
are almost always used is in microphone cables. The reason for this is that the output signal from most microphones is very small, so even a tiny amount of noise will be relatively large, and will be amplified to an alarming
degree in the mixer’s high-gain head amplifier.
Signal Levels and the Decibel
Let’s take a look at one of the most commonly used units in
audio: the decibel (dB). If the smallest sound that can be
heard by the human ear is given an arbitrary value of 1, then
the loudest sound that can be heard is approximately
1,000,000 (one million) times louder. That’s too many digits
to deal with for practical calculations, and so the more appropriate “decibel” (dB) unit was created for sound-related measurements. In this system the difference between the softest
and loudest sounds that can be heard is 120 dB. This is a
non-linear scale, and a difference of 3 dB actually results in a
doubling or halving of the loudness.
You might encounter a number of different varieties of the
dB: dBu, dBV, dBM and others, but the dBu is the basic decibel unit. In the case of dBu, “0 dBu” is specified as a signal
level of 0.775 volts. For example, if a microphone’s output
level is -40 dBu (0.00775 V), then to raise that level to 0 dBu
(0.775 V) in the mixer’s preamp stage requires that the signal
be amplified by 100 times.
A mixer may be required to handle signals at a wide range of
levels, and it is necessary match input and output levels as closely as possible. In most cases the “nominal” level
for a mixer’s input and outputs is marked on the panel or listed in the owner’s manual.

Making the Most of Your Mixer
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. Surprisingly enough, piano also has an incredibly powerful low end that can benefit from a bit of low-frequency roll-off to let other instruments—notably drums and
bass—do their jobs more effectively. Naturally you won’t
want to do this if the piano is playing solo.
The reverse applies to kick drums and bass guitars: you
can often roll off the high end to create more space in the
mix without compromising the character of the instruments.
You’ll have to use your ears, though, because each instrument is different and sometimes you’ll want the “snap” of a
bass guitar, for example, to come through.

musical pitch.
Harmonics: Multiples of the fundamental frequency
that play a role in determining the timbre
of the instrument.
(Hz)
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.
Boost with Caution
If you’re trying to create special or unusual effects,
go ahead and boost away as much as you like.
But if you’re just trying to achieve a good-sounding
mix, boost only in very small increments. A tiny
boost in the midrange can give vocals more presence, or a touch of high boost can give certain
instruments more “air.” Listen, and if things don’t
sound clear and clean try using cut to remove frequencies that are cluttering up the mix rather than
trying to boost the mix into clarity.
One of the biggest problems with too much boost
is that it adds gain to the signal, increasing noise
and potentially overloading the subsequent circuitry.
