YuSynth Dual Balance Modulator

The balanced modulator or four quadrant multiplier, is a great classical module. it provides the same functions as those of a ring modulator. Its main purpose is to generate  sounds with a complex overtone content such as bell sounds and other klang tones !
The principle of this circuit is based on a Gilbert cell contained in the classical LM1496 IC.

Basically, if one feeds the A input with a sinewave with frequency f1, that is sin(2πf1), and the B input with a sinewave with frequenc f2, that is sin(2πf2), one gets at the output the product these two signals, that is sin(2πf1) x sin(2πf2).

Due to trigonomic properties it reads :

 sin(2πf1) x sin(2πf2) = sin(2π(f1+f2)) + sin(2π(f1-f2))

in other words the output is a mixture of two sinewaves, one with frequency f1+f2 and the other with frequency f1-f2.

We all have our preferences when it comes to building our modular synth so we offer a range of products* for the build:

  • PCB
  • Individual components
  • Kit of parts (excluding PCB, knobs and connectors)
  • Knobs (Cliff KM20B)
  • Jack sockets
  • Power connectors
  • Front Panel
  • Back Panel
  • PCB Holder
  • PCB Holder Brackets
  • Panel PCBs
  • Wiring Leads

*Not all products are available at the time of writing but are in development

For the latest build information, we recommend visiting the YuSynth website at http://www.yusynth.net/Modular/index_en.html

However, we also include this build information in our product pages plus additional details relating to the complete module assembly using our front panel solution as they are developed.
