ES04 Overdrive Linear VCA - 7HP


The ES04 is the most simple of the three Voltage Controlled Multipliers (VCM), but it features two switchable effects. With the switch set to the OVERDRIVE position, the module works to "square-up" an incoming signal. This is not the same as a basic comparator squaring function, however, since there is a rounded flattening of the signal peaks: the effect is somewhat similar to overdriving a tube amplifier (but in this version the process is voltage controllable!). With the switch set at the LINEAR VCA position, the module acts as a linear gain controlled VCA. This is useful for many functions like amplitude modulation and gating signals into the other sections.

  • Switch set to Overdrive squares off the peaks of incoming signal
  • Switch set to Linear VCA works as gain controlled VCA
