PRE FADER

The aux send rule of thumb: For parallel

effects processing, use aux sends in post-fader
mode. For stage monitors, use pre-fader mode
(see diagram below).

With this switch disengaged (up), 

AUX 1

and 

2

 receive signals in post-fader mode: post-

low cut, post-insert, post-EQ, post-mute, and
POST-fader. Any changes made to the channel
controls will affect the 

AUX

 signal.

With this switch engaged (down), 

AUX 1

 and

2

 receive signals in pre-fader mode: post-low cut,

post-insert, post-EQ, post-mute, and PRE-fader.
Any changes made to the channel controls,
EXCEPT the fader, will affect the 

AUX

 signal.

In pre-fader mode, you can take the

drummer’s vocals out of the main mix by turn-
ing his fader down, but since he still hears
himself in the monitors, he’s happy.

EFX 1 (EXT)

EFX 1

, designed for feeding the inputs of

parallel effects devices, behaves exactly like an

AUX

 

 send, but it’s always in post-fader

mode: Any changes made to the channel controls
will affect the 

EFX

 signal. The 

PRE FADER

 

switch has no effect on the 

EFX

 sends.

EFX 2 (INT)

EFX 2

 is identical to 

EFX 1

 with one big dif-

ference: In addition to feeding the 

EFX SEND

 jacks, it also feeds the inputs to the 

EMAC

EFFECTS PROCESSOR

 

. If you’re using

EMAC

 and just one outboard processor, patch

the outboard processor via 

EFX RETURN 1

. You

can use 

EMAC

 and an outboard device via 

EFX

2

; just remember that the sends (

EFX 2 (INT)

EFX 2 SEND

 

) and returns (

TO MAIN

MIX

 

) control two devices. The 

PRE FADER

 switch has no effect on the 

EFX

 sends;

they’re always post-fader.

EQ

The CFX Mixer has low shelving, mid peak-

ing, and high shelving EQ. “Shelving” means that
the circuitry boosts or cuts all frequencies past
the specified frequency. For example, boosting
the 

LOW EQ

 knob boosts bass frequencies at

80Hz and below. “Peaking” means that only a
selected “hill” of frequencies surrounding a
center “hilltop” frequency is affected by the
EQ control.

Everything in moderation (including mod-

eration): with EQ, although you can bring
a sound to life, you can also screw things
up. If you max the EQs on every channel,
you’ll get mix mush, not to mention driving
your mix levels near or beyond clipping. So
equalize subtly; use the left sides of the
knobs (cut) as well as the right (boost).

HI EQ

This control provides up to 15 dB of

boost or cut at 12kHz and above, and it is
also flat at the detent. Use it to add sizzle
to cymbals or an overall sense of transpar-
ency or edge to keyboards, vocals, guitar,
and bacon frying. Turn it down a little to
reduce sibilance or hide tape hiss.

MID EQ

Short for “midrange,” this knob provides 15

dB of boost or cut, also flat at the center detent.
Midrange EQ is often considered the most
dynamic, because the frequencies that
define any particular sound are almost
always found in this range. You can create
as many interesting and useful EQ changes
by turning this knob down as well as up.

The mono channels employ a semi-

parametric mid-sweep EQ. In addition to being
able to set the amount of boost, you can “aim”
that boost at a specific frequency; anywhere
from 100Hz to 8kHz.

The stereo channels employ a 2-stage fixed-

frequency 

MID EQ

HI-MID

 is centered at 3kHz;

LOW-MID

 is centered at 400Hz.

LOW EQ

This control provides up to 15 dB of boost or

cut at 80Hz and below. The circuit is flat (no
boost or cut) at the center detent position.
This frequency represents the punch in bass
drums, bass guitar, fat synth patches, and high-
testosterone male singers.

When adding boost to the channel’s low EQ,

simultaneously engaging the 

LOW CUT

 

switch can create an audible low frequency boost
without boosting stage rumble, mic handling
clunks, and breath pops.
