BLIND MONK MODULAR - HARMONIC MULTIPLIER 

 
20hp 
45ma +12V 
45ms -12V 

 

INPUT JACKS 
IN I - Audio IN (+/-5V max) 
IN II - Audio In (+/-5V max) 
CV IN - Control Voltage Input (+/-5V max) 
 
The CV input controls the horizontal offset of the waves which can sound like triangle 
wave pulse width modulation, changing the amplitude of certain frequencies and the 
phase of others. When used with the distortion circuit, actual pulse width modulation is 
achieved. When used in combination with feedback, modulation between different 
distorted subharmonics can be achieved. 
 
OUTPUT JACKS 
OUT - Main output (+/-5V max) 
II-VII - Audio output for the individual harmonics (levels vary 2-3V peak to peak max) 
 
INPUT KNOBS 
IN I - Controls the amount from IN I jack 
IN II - Controls the amount from IN II jack

Page 4: ...complex and unpredictable tones Also control voltages may be applied to either the IN I or IN II jacks but because they arenʼt scaled for CV control the output signal may disappear completely when the CV signal is high Similarly audio rate inputs will work on the CV input but at a lower level While it wasnʼt specifically designed for this purpose in mind triangle wave LFOs can be multiplied using ...
