CMX62 Stereo Console Mixer
Introduction:
In the world of professional sound reinforcement and audio reproduction there is no
room for compromise. It is absolutely vital that the emotions of a performance are projected
to your audience, not just sounds. Your new Crate Audio CMX62 Stereo Console Mixer is a
powerful tool which allows you to successfully bridge the gap between performers and audi-
ence without losing any of the “life” of the performance in the process. No matter what your
particular application, your Crate Audio mixer is ready to meet the challenge with a level of
performance and control unequaled by its competition.
Crate Audio mixers are the result of our many years of experience with high-performance
audio equipment combined with our extensive research and development procedures and guid-
ed by our inherent love of musical performances. Each mixer is built using a variety of innova-
tive construction methods making it truly reliable and incredibly roadworthy. Its diverse features
offer you an extremely high degree of versatility and flexibility regardless of application and it is
designed to keep you constantly in total control of your performing environment, always with
the best possible sound.
Features:
Crate Audio mixers combine the latest technology with contemporary styling and flexible
features. Exceptionally low noise, incredible headroom and outstanding features make the
Crate Audio mixer perfect for use on stage, in the home studio, or for “institutional” use. This
unique mixer offers stereo Tape In and Out jacks with Level controls, switchable Phantom
Power, a level-controllable Headphones jack, dual 12-step LED ladders with Peak indicators,
and more. Each of the six mono input channels offers you the choice of balanced XLR Low-Z
or balanced 1/4" Hi-Z Input jacks, three bands of equalization, a Low Cut switch, a Pan con-
trol, a pre/post switchable Aux send and an Effects send. Gain controls for each mono channel
and signal and peak LEDs for all channels allow for optimum signal-to-noise ratios. High-qual-
ity sliding faders allow smooth and precise control over each channel’s output. Two stereo
line-level input channels are provided for additional flexibility. Every channel features a Group/
Main L/R assign switch and a PFL (pre-fader listen) switch for increased versatility and control.
The stereo channels feature a +4/-10dBv input sensitivity switch to accomodate a wide range of
input signals.
The color-coded knobs help you know at a glance if you’re reaching for a Level knob, an
EQ control, a Pan pot or Master slider.
These mixers are adaptable for mounting in a standard 19” rack if so desired. Your Crate
Audio dealer has the optional rack-mount ears for the mixer.
About this Manual:
This manual is the compilation of many hours of discussions with engineers, musicians,
experts in the field of sound reproduction and novices. While we strive to provide as compre-
hensive and informative a manual as possible, we realize we cannot convey every application
imaginable or answer every possible question. We have endeavored to cover as much as is
practical in this owner’s manual and have provided suggested wiring diagrams for you to use
as a starting point for your application.

The Mono Input Channels (1 – 6):
1

3
MIC IN: An XLR jack for balanced Low-Z mic inputs. When using a condenser mic,
the Phantom Power switch (#63, rear panel - page 7) must be activated.
LINE: A Tip/Ring/Sleeve 1/4” jack for balanced Hi-Z mics, instruments, drum machines,
and similar high impedance line level signals.
1
INSERT: A Tip/Ring/Sleeve 1/4” jack for adding an external signal processor to the
channel. The wiring diagram for this jack is shown on page 13. Applications informa-
tion is shown on pages 8 – 13.

GAIN: Adjusts the input signal level. Proper setting causes the Peak LED (#13) to flash
at strong input signals.
HIGH: Controls the high frequency level for the channel. Allows 15dB @ 12kHz.
Shelving type.
MID: Controls the middle frequency level for the channel. Allows 15dB @ 800Hz.
Bandpass type.
LOW: This controls the low frequency level for the channel. Allows 15dB @ 70Hz.
Shelving type.
•Additional EQ information is on page 14.

LOW CUT: Reduces the low frequency output of the channel at a rate of 18dB per
octave at 75Hz. Active in the up position.
AUX: Controls the level of the signal sent from the channel to the Aux Out master con-
trol (#49). Use as a monitor send (Pre/Post switch, #10, in the “Pre” position) or as an
effects loop send (Pre/Post switch, #10, in the “Post” position).

10 PRE/POST: The signal sent by the Aux control (#9) can be set to either pre-fader (switch
in the “Pre” position) or post-fader (switch in the “Post” position).
9
10
11 EFF: Controls the level of the signal sent from the channel to the Eff Out master control
(#50). Use as an effects loop send.
11
12 PAN: Divides the signal proportionally between the left and right channels of the Main
L/R fader (#60) or the Group 1/2 faders (#59), depending on the setting of the Grp / L/R
switch (#16).
12

15
13 PEAK LED: Illuminates when the input signal level is within 6dB of clipping. Proper set-
ting of the Gain control (#4) will cause this LED to flash only on strong input signals.
14 -20dB LED: Illuminates when the input signal level is above -20dBv. This serves as a
“signal present” LED.
16
15 PFL: This switch, when depressed, sends the channel’s signal to the Monitor master
control (#51). The Output LED Meters (#57) are also switched to monitor this signal,
which is pre-fader. The PFL LED (#55) illuminates to indicate that the Headphones
(#39), Monitor (#42) and LED Meters (#57) are now responding to the PFL selection.
16 GRP / L/R: This switch determines whether the signal is sent to the Group 1/2 master
faders (#59) or the Main L/R master fader (#60).
17 FADER: Controls the level of the signal sent to either the Group 1/2 faders (#59) or the
Main L/R fader (#60), depending on the setting of the Grp / L/R switch (#16).

The Stereo Input Channels (7 – 10):
18 LEFT/MONO: A Tip/Sleeve 1/4” jack for instruments, drum machines, tape/CD chan-
nels and similar high impedance signals. For stereo inputs use this jack for the left
channel input and the Right jack (#19) for the right channel input. For mono inputs
use this jack only.
19 RIGHT: A Tip/Sleeve 1/4” jack for instruments, drum machines, tape/CD channels
and similar high impedance signals. For stereo inputs use this jack for the right chan-
nel input and the Left/Mono jack (#18) for the left channel input. For mono inputs use
the Left/Mono jack (#18) only.
