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 “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 1/4”-terminated cables below may look alike at first, but
upon closer examination their differences become apparent. These cables are illustrated below.

Care must be taken to
avoid using SIGNAL cables
in place of SPEAKER cables
and vice-versa.
Signal cables aren’t made
to handle the power which
speaker cables do; speaker
cables are not shielded and
pick up external signals,
resulting in excessive hum
and buzzing.
