Func

Analog multiplier/divider

A simple AD633-based multiplier and divider, for Loudest Warning format.

Func is a basic AM-modulator based on a four quadrant multiplier chip, the AD633. This little chip is easy to use and sounds great.

Sections

• Audio input (Carrier) with attenuation control
• Modulator inputs, simultaneously DC-coupled and AC-coupled with attenuation
• Voltage-controlled offset with attenuation
• Multiply/divide modes: the first is smooth AM, the second is harsh distortion
• Initial gain (Init), i.e carrier bleed.

This module was designed to overdrive quite easily the signal with softclip, so it mostly oriented towards audio processing rather than precise multiplication.
