Description

The VU002 is a Video Quad frequency doubler: each stage doubles the signal frequency and they are chained together to multiply the signal at the input by 16. Switching jacks allow the user to break the connection between each stage to use each one individually.

One stage can be used to:

– convert a ramp/saw signal to triangle signal
– multiply a triangle signal by a factor of 2
– multiply a sine signal by a factor of 2 (output sine is glitched)
– solarize a video signal

Inputs: 0-1V, 100kohms
Outputs: 0-1V, 499 ohms
