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
The high EQ for each channel is a “shelving” type, with an action point (+6dB) at 2.5kHz, reaching maximum effect at 12kHz and above.
The middle EQ for each channel is a “peaking” type, which affects frequencies from 300Hz to 2.5kHz, centered on 800Hz.
The low EQ for each channel is a “shelving” type with an action point (+6dB) at 300Hz, reaching maximum effect at 70Hz 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. The three
