CSM8/12/16/24 Console Mixer The Input Channels: 1. LOW Z INPUT: The signal output from a low impedance microphone or a low impedance line level signal (such as a line out signal from an instrument ampli- fier) may be connected here by means of a shielded cable terminated with a male XLR plug. Pin 2 = “+,” pin 3 = “–,” and pin 1 = shield. 2. HIGH Z INPUT: The signal output from a high impedance microphone or a line 1 level signal (such as an instrument, rhythm machine, tape deck, etc.) may be con

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
