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 audience 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 guided by our inherent love of musical performances. Each mixer is built using a variety of innovative 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 control, 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-quality 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 comprehensive 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.

CMX62 Stereo Console Mixer

The Mono Input Channels (1 – 6):

1 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.

2 LINE: A Tip/Ring/Sleeve 1/4” jack for balanced Hi-Z mics, instruments, drum machines,

and similar high impedance line level signals.

3 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 information is shown on pages 8 – 13.

4 GAIN: Adjusts the input signal level. Proper setting causes the Peak LED (#13) to flash

at strong input signals.

5 HIGH: Controls the high frequency level for the channel. Allows ±15dB @ 12kHz.

Shelving type.

6 MID: Controls the middle frequency level for the channel. Allows ±15dB @ 800Hz.

Bandpass type.

7 LOW: This controls the low frequency level for the channel. Allows ±15dB @ 70Hz.

Shelving type.

•Additional EQ information is on page 14.

8 LOW CUT: Reduces the low frequency output of the channel at a rate of 18dB per

octave at 75Hz. Active in the up position.

9 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).

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.

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).

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.

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 channel input and the Left/Mono jack (#18) for the left channel input. For mono inputs use the Left/Mono jack (#18) only.

20 HIGH: Controls the high frequency level for the channel. Allows ±15dB @ 12kHz.

Shelving type.

21 MID: Controls the middle frequency level for the channel. Allows ±15dB @ 800Hz.

Bandpass type

22 +4/-10 SWITCH: This sets the input sensitivity of the channel to either +4dBv for use

with professional equipment (such as DAT players, mic preamps, etc.) or -10dBv for use with semi-pro equipment (such as tape decks, CD players, etc.).

23 LOW: This controls the low frequency level for the channel. Allows ±15dB @ 70Hz.

Shelving type.

•Additional EQ information is on page 14.

24 AUX: Controls the level of the signal sent from the channel to the Aux Out master

control (#49). Use as a monitor send (Pre/Post switch, #25, in the “Pre” position) or as an effects loop send (Pre/Post switch, #25, in the “Post” position).

25 PRE/POST: The signal sent by the Aux control (#24) can be set to either pre-fader

(switch in the “Pre” position) or post-fader (switch in the “Post” position).

26 EFF: Controls the level of the signal sent from the channel to the Eff Out master con-

trol (#50). Use as an effects loop send.

27 BAL: 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 (#31).

28 PEAK LED: Illuminates when the input signal level is within 6dB of clipping. Proper

setting of the input signal level and the +4/-10 switch (#22) will cause this LED to flash only on strong input signals.

29 -20dB LED: Illuminates when the input signal level is above -20dBv. This serves as a

“signal present” LED.

30 PFL: This switch, when depressed, sends the channel’s signal to the Monitor master

31 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).

32 FADER: Controls the level of the signal sent to either the Main L/R fader (#60) or the

Group 1/2 faders (#59), depending on the setting of the Grp / L/R switch (#31).
