ARBA - Quad VCA

ARBA provides four Voltage Controlled Amplifiers (VCA) with linear response. It may look like a simple VCA module but under the hood it is packed with features that unleash a variety of uses.
 

Three features that distinguish ARBA:

  • Normalization: Everything is normalized to everything – all of the inputs, CV inputs and

    outputs are normalized between the four channels so you can use a variety of configurations depending on how you patch it.
    As a result of this feature, you can get a significant gain boost (with CV control!) when you chain several channels together.
     

  • Variable sensitivity: Unlike most VCA's in Eurorack that clip easily due to the 5V unity gain – the cause of this annoying clipping is that many envelope generators output a standard voltage of 8V – with ARBA you can set the sensitivity of each of the channels (or - how much voltage needs to reach the CV input to get unity gain at the output) using the four trimmer resistors located on the back of the module.
     

  • Limiters: soft clipping diodes will limit the outputs to 10.2 volts peak-to-peak and warm up the sound (the limiters can be disabled using switches on the back of the module).
     

    The combination of these three features allows a variety of uses, for example:

    Quad simple linear VCAs Stereo VCAs
    Summing VCAs
    Soft clipper

    Distortion with CV control
    Level booster (instrument or line level to Eurorack level) And much more...
