Mackie CFX12, CFX16, CFX20 Parts list
CFX™ Series
CFX SERIES 12-, 16-, and 20-Channel Mic/Line Mixers
Introduction
The CFX
pact mixers, each having a stereo graphic equalizer and
digital effects built in. The EMAC™ 32-bit digital effects
processor was custom designed by our digital engineers
and rivals the sound of many high-quality
outboard processors.
Like all Mackie mixers, the CFX Series mixers are
designed for rugged, day-in and day-out road use. Their
sturdy-yet-light steel monocoque construction houses
rugged, double-sided SMT-plated berglass circuit
boards, and 60 mm faders with ultra-tight lip seals
for keeping out dust and other contaminants. Impactresistant knobs are mounted so they “ride” just above
the steel chassis––they absorb impact without trouble.
Furthermore, they’re designed to last, thanks to co-molded potentiometers that do not get brittle and crack up.
Metal stand-offs are used at regular intervals to mount
thick berglass circuit boards inside the mixer. These are
extremely exible mixers, not only because of their multiple input/output congurations, but also because of their
4 subgroups, 9-band graphic EQ, and built-in
digital effects.
The CFX•12 has eight mic/line channels and two stereo
line input channels, the CFX•16 has 12 mic/line channels
and two stereo line input channels, and the CFX•20 has
16 mic/line channels and two stereo line input channels. All mic/line channels have unbalanced inserts. Each
channel strip has one external and one internal/external
effects send plus two aux sends, pan, mute, solo (PFL),
bus assigns, and 60 mm log-taper fader. The mic/line
channels also have input trim controls with individual
Zero Level LEDs, 3-band EQ with swept midrange, and
100 Hz low cut lters. Two separate stage monitor mixes
can be created with their own effects levels.
The CFX Series is a true 4-bus mixer, with four sub
bus faders and master ganged Left/Right fader. Outputs
include XLR and TRS balanced/unbalanced main outputs,
a 75 Hz low-pass subwoofer XLR output, extra TRS

20-Channel Mic/Line Mixers
CFX Series Dimensions
add effects to stage monitor mixes independently of
the EFX levels added to the main mix. Below the level
controls is the preset selector for picking which effect
you want. The characteristics of these presets can be
changed with the TIME/RATE and DAMPING/DEPTH
knobs. Between these controls are a BYPASS SWITCH
and an EFX WIDE control. Wide adds psychoacoustic
“width” or “depth” to all effects except delay and
phaser.
The Stereo Graphic Equalizer is nine bands with
+15 dB of gain and centers at 63 Hz, 125 Hz, 250 Hz,
500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz. This
EQ is exceptionally low-noise, low-distortion, and free
of phase distortion.
Trim Controls have 50 dB of mic gain, +30 dB of
line-level gain, and a full 15 dB of attenuation to
“pad” hot signals. Each channel also includes a Zero
(continued from page 1)
Utility outputs that are independent of the master gain
control, and tape and sub bus outputs.
The EMAC Digital Effects section includes four con-
trols at the top. EFX 2 regulates the signal level being
sent to the EMAC effects processor from an individual
channels strip’s EFX 2 aux send. The overall level is
monitored by the CLIP LED to prevent overload. TO
MAIN MIX controls the amount of effects sent to your
main mix. The two EFFECTS TO MONITOR knobs let you
Level Set LED for easy level setting. All mic channels
have a 100 Hz low cut lter to reduce stage vibration, mic stand rumble, and wind noise. Each channel
includes a Pre-Fader Solo switch.
Channel EQs are as follows: 12 kHz shelving HIGH
frequency EQ, sweepable peaking Midrange EQ
(only on mono input channels), with a 100 Hz to 8
kHz bandwidth. Stereo channels employ a 2-stage
xed-frequency MID EQ, HI-MID is centered at 3 kHz;
LOW-MID is centered at 400 Hz; and a LOW EQ that is
shelved at 80 Hz.
Log-taper 60 mm faders deliver a consistent fade
throughout the fader’s throw. These faders have a
co-polymer membrane that provides a continuously
sealed barrier against dust and liquids without interfering with fader travel. Similarly, the fader’s longwearing contact material (rst designed for use in
exterior automotive sensors) means longer fader life
and improved resistance to the elements.
The CFX Series mixers are designed for continuous,
hassle-free use in any sound reinforcement installation. And they’re packed with useful features and
practical routing capabilities. Simply stated, these
mixers offer more features, more peace of mind, and
more possibilities than any other mixers in their class.
And they're Mackies.
