Synth-Werk - SW905 Reverberation Unit

The SW905 Reverberation Unit utilizes a dual springtype acoustic delay line to produce a succession of decaying echoes of an audio signal. A single panel control determines the ratio between the amounts of reverberated and non-reverberated signals that appear at the output jack. In addition the SW905 offers two modes of operation:

Regular mode
the relative amount of the echo signal and direct signal can be continuously changed from 100% direct signal to 100% echo signal.

„Emerson“ modification
the output signal is continuously mixed with the direct signal and the knob on the faceplate controls the level of the mix. The direct signal is passed through unaffected.

Both modes of operation can be selected on the board of the module.
 

MUSICAL APPLICATION 

When a dynamically varying signal is applied to the input of the SW905, the output will consist of a series of closely spaced echoes, the subjective effect of which is similar to that of reverberation of sound. When a static signal is applied to the input of the SW905, the output will also be static. The SW905 will perform in this application like a formant filter, strongly coloring the timbre of any signal with appreciable harmonic content.

This Module is based on the original design from 1967
