KEMPER PROFILING AMPLIFIER40

 Peak Spread

You cannot ﬁnd this parameter in any vintage phaser, because it would have been too expensive to realize

in the analog domain. With “Peak Spread” you can control the spread and width of the phaser peaks and

notches in the frequency domain over a wide range. At a narrow setting (more to the left), you can hear

the phaser peaks being focused to a narrow ﬁeld. At a wider spread the phaser seems de-coupled, and

dominates the whole sound spectrum.

 Stages

You can select the number of phaser stages from 2 to 12, in steps of two. The more stages you select, the

more complex and diuse the phaser sound becomes.

 Stereo

Osets the phaser modulation of the left and right signals. With extreme left or right settings, the modula-

tion will go in opposite ways. At the middle position (zero), the phaser will be mono. Use small deviations

to the left or right of zero to achieve a gentle stereo eect.

Flanger

The Flanger eect shares the same heritage as the Phaser, and the resulting sound is somewhat related,

too. This is why we put both in the same eect family with color code Magenta (Purple). However, the

Flanger is not based on analog ﬁlter technology, but on very short bucket-brigade delays.

The parameter set for the Flanger is almost the same as on the Phaser; only the parameters “Peak Spread”

and “Stages” are not available.

Thanks to the overlapping parameter set, you can switch back and forth between Phaser and Flanger with-

out altering the basic parameter values.
