CMX62 Stereo Console Mixer Congratulations. You have selected one of the finest pieces of Audio Reproduction Equipment available for use on stage, in the home studio, or for “institutional” use: a Crate Audio Stereo Console Mixer. In order to derive the most benefit from the mixer, and to fully understand and appreciate its flexibility and versatility, please familiarize yourself with the mixer by reading through this User’s Guide prior to its use. Thank You, from Crate Audio.
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 audience without losing any of the “life” of the performance in the process.
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.
CMX62 Stereo Console Mixer The Stereo Input Channels (7 – 10): 18 LEFT/MONO: 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 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.
CMX62 Stereo Console Mixer The Master Section: 33 AUX RET: Returns the stereo or mono signal from an external device. Stereo devices use both the Left and Right jacks; mono devices use only the Left jack. 33 34 34 EFF RET: Returns the effected signal from an external effects device. Stereo devices use both the Left and Right jacks; mono devices use only the Left jack. 35 36 38 40 35 TAPE IN/TAPE OUT: Connect to the record and play jacks of an external tape deck. (See page 13.
CMX62 Stereo Console Mixer The Master Section (continued): 48 TAPE IN PFL: This switch, when depressed, sends the signal from the tape In jacks (#35) to the Monitor master control (#51). The Output LED Meters (#57) are also switched to monitor this signal, which is pre-level control. The PFL LED (#55) illuminates to indicate that the Headphones (#39), Monitor (#42) and LED Meters (#57) are now responding to the PFL selection.
CMX62 Stereo Console Mixer Applications: Basic Mono Operation: This example shows how the mixer and one stereo power amplifier* may be used to run both the house speakers and the stage monitors. Connect a signal cable between the mixer’s Mono jack and the power amp’s Channel 1 Input jack (A). Connect another signal cable between the mixer’s Aux Out jack and the amp’s Channel 2 Input jack (B). A graphic equalizer may be included in the signal chain as shown.
CMX62 Stereo Console Mixer Applications: Home Studio: In this example the Main L/R outputs are connected to a computer through a compressor. The Monitor outputs are connected to the monitor power amp which drives the studio monitors. The output of the computer may be connected to the stereo channel 9/10 of the mixer and the remaining audio sources may be connected to the various other inputs as shown. With this type of setup you will need to establish two different buses.
CMX62 Stereo Console Mixer Applications: DJ Setup: In this example the mixer is connected to a stereo power amplifier which drives the house speakers. Connect a pair of signal cables between the mixer’s Main Left and Right jacks and the stereo power amplifier’s* Channel 1 and Channel 2 Input jacks (A). Connect a speaker cable between the power amp’s Channel 1 Speaker Output and one of the house speakers (B).
CMX62 Stereo Console Mixer Applications: House of Worship: In this example the mixer’s Main Outs are used for the sanctuary mix, the Aux outs are used for a platform mix, and a mono signal is provided for the childcare room (or other remote location). Connect signal cables between the mixer’s Main Left and Right jacks and the Input jacks of the sanctuary speakers’ stereo power amp* (A).
CMX62 Stereo Console Mixer Applications: Separating Vocals and Instruments: In this example the Pan controls on all of the vocal mic channels are rotated fully clockwise to assign all vocal mics to the right channel. The instrument channels are then all assigned to the left channel by rotating their Pan controls fully counter clockwise. Two pairs of speakers are required: one for the vocals and another for the instruments. An additional amplifier will drive the monitors.
CMX62 Stereo Console Mixer Applications: External Effects and Recorders: There are several ways to use the CMX62 with external signal processors (such as effects and delay units, limiters, etc.). For example, any (or all) of the six mono channels may have its own processor patched in by use of the Insert jack (#3, page 4). Effects may also be patched in through the Aux or the Effects Out and Return jacks. Both the Aux and the Effects loops will accommodate stereo as well as mono effects.
CMX62 Stereo Console Mixer Equalization Diagrams: Each input channel of the CMX62 has three bands of equalization which allows you to alter the tonal characteristics of the input signal. The EQs may be used to add “color” or to compensate for inadequacies of the original signal. They also may be used to cut frequencies which cause unnatural sounds or to de-emphasize over-pronounced tones and to reduce acoustic feedback. Each EQ has a range of 30dB (+/-15dB).
