KEMPER PROFILING AMPLIFIER46
When “Feedback” is at zero, there will only be one audible repeat. As you increase the feedback, the num-
ber of repeats increase until, at 100% (center position), the delayed signal will continue repeating infinitely.
As you push the values above 100% the delay is slowly driven into the tape saturation. You will notice that
the first values above 100% have a very fine resolution - this allows for very subtle control over the amount
of tape saturation.
 “Delay Feedback” can be controlled with the dedicated knob in the upper half of the panel.
 Bandwidth
This parameter gives you access to the delay’s bandpass filter mentioned above. When set to zero, there
is no sound coloration whatsoever. Increasing the parameter will narrow the bandwidth - at first you will
notice a gentle attenuation of the high frequencies, that will cumulate with every delay repetition. As you
narrow the bandwidth a bit more, the same will happen to the bass frequencies. When you turn “Band-
width” beyond the center position, you can clearly hear the character of the bandpass filter: after just a
few repetitions the center frequency of the filter will resonate more and more.
 Center Frequency
This parameter lets you adjust the center frequency of the bandpass filter. You will find a nice, standard
value at the center position, perfect for most applications. However, when “Bandwidth” and “Feedback”
are set to higher values, the center frequency becomes clearly audible, creating a distinct, musical tone
that you might want to tune to your music. This is why the “Center Frequency” is not only labeled in hertz,
but also in musical semi-tones that can be precisely adjusted!
 Modulation
This parameter will add slight deviations to the left and right delay independently, creating a nice stereo
eect and de-coupling the delay from the dry signal. With higher values you will create a wow and flutter
eect, typical of a tape delay.
