Morpheus Operation Manual46

EFFECTS SECTION

• Stereo Flanger

A flanger consists of a short audio delay line whose output is mixed

together with the original signal. Mixing the delayed and original

signals together results in multiple frequency cancellations creating a

comb filter effect as shown in the diagram below. Since the flanger is a

type of filter, it works best with harmonically rich sounds such as

strings.

The flanging effect was originally created using two tape recorders

playing identical recordings. By exactly synchronizing the two decks

and then slowing the speed of one by grasping the tape reel flanges,

the flanging effect was born.

The flanger in the Morpheus is a stereo device consisting of two sepa-

rate delay lines controlled by a single set of controls. The block dia-

gram of the flanger is shown below.
