29. PFL LEFT/RIGHT/MIX: These switches, when depressed, send the corresponding PFL signals to the headphones/PFL jack (#28) and to the PFL output jack (#18). 30. AUX 1 MASTER FADER: Use this control to set the overall output signal level at the aux 1 send jack (#17, page 5). A fader has been chosen to provide ease of control of aux 1 since this is typically used as an output signal for the stage monitors. 31. LEFT/RIGHT MASTER FADERS: Use these controls to set the overall output signal levels at the left and right balanced output jacks (#15, page 5), as well as the signal level sent to the mix master fader (#32). 32. MIX MASTER FADER: Use this control to set the overall output signal level at the mix balanced output jacks (#15, page 5). The left and right master faders (#31) must be set at an appropriate level so that a signal of sufficient amplitude is sent to the mix master fader. CSM8/12/16/24 Console Mixer Equalization Diagrams: Each input channel of the CSM8/12/16/24 has three bands of equalization which let you 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 to help eliminate unnatural sounds or to de-emphasize over-pronounced tones, and to help prevent acoustic feedback. Each EQ has a range of 30dB (+/-15dB). •The high EQ for each channel is a “shelving” type, with an action point (+6dB) at 6kHz, reaching maximum effect at 10kHz and above. •The middle EQ for each channel is a “peaking” type, which affects frequencies from 800Hz to 5kHz, centered at 2kHz. •The low EQ for each channel is a “shelving” type with an action point (+6dB) at 250Hz, reaching maximum effect at 100Hz and below. Differences in Cable Types: This manual makes reference to different types of cables; in particular, balanced and unbalanced signal cables and speaker cables. These are not the only types of cables associated with sound reinforcement, but they are similar enough to each other to warrant a more descriptive explanation. For example, the three 1/4”-terminated cables below may look alike at first, but upon closer examination their differences become apparent. BALANCED SIGNAL CABLE: TIP Care must be taken to avoid using SIGNAL cables UNBALANCED SIGNAL CABLE: in place of SPEAKER cables TIP and vice-versa.

Each of the mixer’s input channels has its own Insert jack, allowing a processor to be used on that particular channel. Figures 1 and 2 below show two ways of connecting a signal processor to the channel Insert jacks. The mixer’s master section has two stereo effects loops available (Aux 3 and Aux 4), allowing a processor to be added to any or all of the input signals. Figures 3 and 4 below show the basic connection of two types of stereo processors to the aux loops. Each channel’s Aux 3 and Aux 4 levels control the amount of signal sent from each channel to the aux loops. The master Aux 3 and Aux 4 Send, Return and Pan control the amount of signal sent to the processor, the amount of processed signal returned to the mix, and how much of the processed signal is applied to the left and right output signals. (See pages 4 through 6 for additional information on the insert jacks, the aux loops, and their controls.)
