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.

noise level will be
the ultimate
deciding factor, but
balanced is best.

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.

Mixer Basics

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.

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 good­sounding 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.

Making the Most of Your Mixer

Ambience

Your mixes can be further refined by adding
ambience effects such as reverb or delay. The MG’s
internal effects can be used to add reverb or delay
to individual channels in the same way as external
effects processors. (Refer to page 13).

Reverb and Delay Time

The optimum reverb time for a piece of music will
depend on the music’s tempo and density, but as a
general rule longer reverb times are good for
ballads, while shorter reverb times are more suited
to up-tempo tunes. Delay times can be adjusted to
create a wide variety of “grooves”. When adding
delay to a vocal, for example, try setting the delay
time to dotted eighth notes corresponding to the
tune’s tempo.

Reverb Tone

Different reverb programs will have different “reverb
tone” due to differences in the reverb time of the
high or low frequencies. Too much reverb,
particularly in the high frequencies, can result in
unnatural sound and interfere with the high
frequencies in other parts of the mix. It’s always a
good idea to choose a reverb program that gives
you the depth you want without detracting from the
clarity of the mix.

Reverb Level

It’s amazing how quickly your ears can lose
perspective and fool you into believing that a totally
washed-out mix sounds perfectly fine. To avoid
falling into this trap start with reverb level all the way
down, then gradually bring the reverb into the mix
until you can just hear the difference. Any more than
this normally becomes a “special effect.”

For chorus and flanging the signal is delayed by
several milliseconds, with the delay time modulated
by an LFO, and recombined with the direct signal. In
addition to the phasing effect described above, the
delay modulation causes a perceived pitch shift
which, when mixed with the direct signal, results in a
harmonically rich swirling or swishing sound.
The difference between chorus and flanging effects
is primarily in the amount of delay time and
feedback used—flanging uses longer delay times
than chorus, whereas chorus generally uses a more
complex delay structure. Chorus is most often used
to thicken the sound of an instrument, while flanging
is usually used as an outright “special effect” to
produce otherworldly sonic swoops.

Compression

One form of compression known as “limiting” can,
when properly used, produce a smooth, unified
sound with no excessive peaks or distortion. A
common example of the use of compression is to
“tame” a vocal that has a wide dynamic range in
order to tighten up the mix. With the right amount of
compression you’ll be able to clearly hear whispered
passages while passionate shouts are still well
balanced in the mix. Compression can also be
valuable on bass guitar. Too much compression can
be a cause of feedback, however, so use it
sparingly.
Most compressors require several critical
parameters to be set properly to achieve the desired
sound. The MG compressor makes achieving great
sound much easier: all you need to do is set a single
“compression” control and all of the pertinent
parameters are automatically adjusted for you.

The Modulation Effects:

Phasing, Chorus, and Flanging

All of these effects work on basically the same
principle: a portion of the audio signal is “time­shifted” and then mixed back with the direct signal.
The amount of time shift is controlled, or
“modulated”, by an LFO (Low-frequency Oscillator).
For phasing effects the shift is very small. The
phase difference between the modulated and direct
signals causes cancellation at some frequencies
and reinforces the signal at others and this causes
the shimmering sound we hear.

jack and a LINE input jack, or a LINE input jack and
an RCA pin jack, you can use either jack but not both
at the same time. Please connect to only one jack on
each channel.

5 INSERT Jacks (CHs 1, 2)

Each of these jacks provides an insert point between the
equalizer and level control of the corresponding input chan­nel (CHs 1, 2). The INSERT jacks can be used to indepen­dently connect devices such as graphic equalizers,
compressors, or noise filters into the corresponding channels.
These are TRS (tip, ring, sleeve) phone jacks that carry both
the send and return signal (tip = send/out; ring = return/in;
sleeve = ground).

NOTE

Patching external devices via an INSERT jack
requires a special insert cable such as illustrated
below (insert cable sold separately).

6 GAIN Control

Adjusts the input signal level.
To achieve the best balance between S/N ratio and dynamic
range, adjust the level so that the PEAK indicator
only occasionally and briefly on the highest input transients.
The -60 to -16 scale is the MIC input adjustment range. The

-34 to +10 scale is the LINE input adjustment range.

7 Switch (High Pass Filter)

This switch toggles the HPF on or off. To turn the HPF on,
press the switch in ( ). The HPF cuts frequencies below 80
Hz (the HPF does not apply to the line inputs of stereo input
channels

34).

8 COMP Control

Adjusts the amount of compression applied to the channel.
As the knob is turned to the right the compression ratio
increases while the output gain is automatically adjusted
accordingly. The result is smoother, more even dynamics
because louder signals are attenuated while the overall level
is boosted.

NOTE

Avoid setting the compression too high, as the the
higher average output level that results may lead to
feedback.

9 PEAK Indicator

The peak level of the post-EQ signal is detected, and the
PEAK indicator lights red when the level reaches 3 dB below
clipping. For XLR-equipped stereo input channels (3/4 and
5/6), both the post-EQ and post-mic-amp peak levels are
detected, and the indicator lights red if either of these levels
reaches 3 dB below clipping.

0 Equalizer (HIGH, MID, and LOW)

This three-band equalizer adjusts the channel’s high, mid,
and low frequency bands. CH 7/8 (CHs 7/8, 9/10) have two
bands: high and low. Setting the knob to the t position pro­duces a flat response in the corresponding band. Turning the
knob to the right boosts the corresponding frequency band,
while turning to the left attenuates the band. The following
table shows the EQ type, frequency, and maximum cut/boost
for each of the three bands.

BAL Control (CH 7/8 (CHs 7/8, 9/10)

The PAN control determines the stereo positioning of the
channel signal on the Stereo L and R buses.
The BAL control knob sets the balance between left and right
channels. Signals input to the L input (odd channel) go to the
Stereo L bus; signals input to the R input (even channel) go to
the Stereo R bus.

NOTE

On channels where this knob provides both PAN and
BAL control (channels 3/4 and 5/6), the knob oper­ates as a PAN control when input is received via the
MIC jack or L (MONO) input only, and as a BAL
control when input is received via both L and R
inputs.

C Level Control

Adjusts the level of the channel signal. Use these knobs to
adjust the balance between the various channels.

NOTE

Set the controls for unused channels all the way down
to minimize noise.

1 2TR IN Jacks

These RCA pin jacks can be used to input a stereo sound
source. Use these jacks when you want to connect a CD
player directly to the mixer.

NOTE

Select where you want to send the signal using the
2TR IN switch, and adjust the signal level using the
2TR IN control in the Master Control section.

2 REC OUT (L, R) Jacks

These RCA pin jacks can be connected to an external
recorder such as an MD recorder in order to record the same
signal that is being output via the STEREO OUT jacks.

NOTE

The mixer’s STEREO Master control has no affect on
the signal output via these jacks. Be sure to make
appropriate level adjustments at the recording device.

3 RETURN L (MONO), R Jacks

These are unbalanced phone-jack type line inputs. The signal
received by these jacks is sent to the STEREO L/R buses.
These jacks are typically used to receive the signal returned
from an external effect device (reverb, delay, etc.).

NOTE

These jacks can also be used as an auxiliary stereo
input. If you connect to the L (MONO) jack only, the
mixer will recognize the signal as monaural and will
send the identical signal to both the L and R jacks.

4 SEND EFFECT (AUX) Jack

This is an impedance balanced* phone-jack type output that
outputs the signal from the EFFECT (AUX) bus. You can use
this jack, for example, to connect to an external effect unit.

5 STEREO OUT (L, R) Jacks

These are impedance balanced* phone-jack type outputs that
output the signals adjusted by the STEREO Master control.
You can use these jacks, for example, to connect to the power
amplifier driving your main speakers.

6 MONITOR (L, R) Jacks

These are impedance balanced* phone-jack type outputs that
output the signals adjusted by the MONITOR/PHONES con­trol. Connect these jacks to your monitor system.

7 PHONES Jack

Connect a pair of headphones to this stereo phone jack. The
PHONES jack outputs the same signal as the MONITOR
OUT jacks.

8 PHANTOM +48 V Switch

This switch toggles phantom power on and off. When the
switch is on the mixer supplies +48V phantom power to all
channels that have XLR mic input jacks (CHs 1–5/6).
Turn this switch on when using one or more phantom-pow­ered condenser microphones.

NOTE

When this switch is on the mixer supplies DC +48 V
power to pins 2 and 3 of all XLR-type MIC INPUT
jacks.

•

Be sure to leave this switch off ( ) if you do
not need phantom power.

•

CAUTION

When tuning the switch on ( ), be sure that
only condenser mics are connected to the XLR
input jacks (CHs: 1 to 5/6). Devices other than
condenser mics may be damaged if connected
to the phantom power supply. Note, however,
that the switch may be left on when connecting
to balanced dynamic microphones.

•

To avoid damage to speakers, be sure to turn off
amplifiers (or powered speakers) before turning
this switch on or off. We also recommend that
you turn all output controls (STEREO Master
control, etc.) to their minimum settings before
operating the switch to avoid the risk of loud
noises that could cause hearing loss or device
damage.

0 POWER Indicator

This indicator lights when the mixer’s power is ON.

A Level Meter

This LED meter displays the level of the signal sent to the
MONITOR jacks and the PHONES jack. The “0” segment
corresponds to the nominal output level. The PEAK segment
lights red when the output reaches the clipping level.

B 2TR IN

• 2TR IN Switch

If it is set to TO STEREO ( ), the signals are sent to the
STEREO L/R buses. If this switch is set to TO MONITOR
( ), the signals input via the 2TR IN jacks are sent to the
MONITOR OUT jacks, the PHONES jack, and the level
meter. The MONITOR MIX feature becomes available when
it is set to TO MONITOR ( ).
