SW 1630 BODE FREQUENCY SHIFTER
A frequency shifter is an audio signal modifier which shifts the entire frequency spectrum of the applied signal by a given amount. The Model SW 1630 Bode Frequency Shifter allows the amount of shift to be accurately and continuously controlled over a span of -5000 Hz to +5000 Hz, utilizing voltage and/or manual control. The relationship between the control voltage sum and the amount of shift may be either linear or exponential. Up-shifted and down-shifted outputs, as well as a continuously variable mixture of the two, are available simultaneously and independently. Variable threshold squelch and zeroadjust fine tuning controls are provided.
The Model SW 1630 Bode Frequency Shifter changes the ratios between the frequency components of an audio spectrum, thus producing a variety of novel sound quality transformations. Applications include a wide variety of tone color modification, P.A. feedback suppression, linear frequency modulation, novel tape feedback effects, and the generation of dynamically varying clangorous tones.
In shifting the components of the input audio spectrum by a given amount, the SW 1630 Bode Frequency Shifter changes the original ratios between the overtones and other frequency components of the input signal. Rather than being a transposing device, this instrument is a means for achieving an extremely wide variety of tone color modification. Whether the amount of frequency shift is large or small, static or time varying, or whether the input signal is simple or complex, the processed outputs will generally be musically interesting.
