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 anoth- er 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. Use the Main L/R bus to

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. The vocal speakers shoul

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. The ill

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). The high EQ for each channel is a “sh
