The Cherry Audio Poly Amplifier is a voltage-controlled amplifier (VCA) for polyphonic audio or CV signals. If you need a refresher on how VCAs work, check out the documentation for the standard Amplifier module.

Below is a simple polyphonic patch where the Poly Amplifier is modulated by a Poly Envelope Generator to control the volume of a Poly Oscillator.

Inputs, Outputs, and Controls

Input jack- Use this jack to patch in "poly" audio or control signals to be affected by the Poly and/or Mono CV Mod jacks.

Gain- Adds up to 5 volts of gain. This works in addition to incoming CV Mod jack voltages. It's also useful for manually "opening" the amplifier.

Poly CV Mod jack and attenuator- This is a "poly" CV input and bipolar attenuator for individually controlling the amplitude of the signals received at the Input jack.

Mono CV Mod jack and attenuator- Standard "mono" CV input and bipolar attenuator for simultaneously controlling the amplitude of all signals received at the Input jack.

Response - Lin/Expo- These select the "curve" of the amplifier's response as the input CV rises from 0 to 5V. Lin or linear response curve is equally proportional across the voltage input range, where as an Expo or exponential curve is closer to how the human ear perceives volume. With that in mind, you'll likely want to use the Lin setting for modulation or control voltage situations, and use the Expo setting when an envelope generator is used to control an audio signal with the amplifier.

Output jacks- The Output jack carries the CV-modified version of the polyphonic input signal. The Inv Out jack outputs an inverted version of the same "poly" signal. Be careful not to use both at the same level as they can cancel the output entirely.
