Quad VCA

Quad Voltage Controlled Amplifier and Cascaded Mixer

Oh My Quad...

When you get into eurorack, you'll inevitably come across the old addage—you can never have enough VCAs. It's true, but it's a bit over simplified, the Quad VCA is not. Each of the four VCAs has independant level control, bipolar CV inputs with attenuators and led indicators, adjustable linear/exponential response and and a +6dB boost switch to double the channels output. Each channel's CV inputs are cascaded to the next, as are its outputs so that you can create submixes.

Voltage Controlled Quadrifier

The Quad VCA comprises four channels of voltage controlled amplifiers. Each channel is equipped with a 6db boost, a LEVEL control, and the CV input response can be swept between linear and exponential. Additionally, the outputs of these channels are cascaded from left to right, allowing Quad VCA to function as a four channel mixer.

Features

  • Manual LEVEL control per VCA which is convenient when using the module as a mixer or for biasing when CV modulating the VCA with a bipolar LFO.
  • Dedicated CV attenuators with dual color LEDs for monitoring bipolar CV signals.
  • Continuously adjustable response from linear to exponential per VCA.
  • Each CV input is normalled to the adjacent one for cascaded control.
  • Each output is normalled to the mix input of the adjacent one which allows you to use adjacent sets as submixes or the fourth output can be used as a master mix output when none of the other outputs are patched.
  • Each VCA has a boost switch that increases the output level by approximately 6dB (double).
