The VM923 is a multi-function modules featuring white and pink noise as well as independent single-pole 6 dB/oct low pass and high pass filters.

Inputs, Outputs, and Controls

Low Pass and High Pass Filters

Low Pass frequency- Sets the cutoff frequency of the low pass filter from 10 hz to 10 kHz.

In jack- Patch low pass filter inputs signals here.

Out jack- The output of the low pass filter.

High Pass frequency- Sets the cutoff frequency of the high pass pass filter from 10 hz to 10 kHz.

In jack- Patch low pass filter inputs signals here.

Out jack- The output of the low pass filter.

Noise Source

White noise output jacks - Two identical outputs for white noise. White noise is a random signal in which all frequencies across the frequency spectrum are represented equally, and is useful for wind and surf effects.

Pink noise output jacks - Pink noise is a random signal in which each octave across the frequency spectrum is represented equally. It tends to sound darker and bassier, and often works better as a mod source if you don't want total chaos.

Pink Lady was a short-lived Japanese novelty vocal duo from 70s. They briefly had their own NBC variety show, back when that corny crap was the business (kinda literally). It later was changed to Pink Lady and Jeff, but we don't talk about him, ok?
