Expert Sleepers Ivo is a fully analog resonant lowpass VCF module that implements discrete transistor OTA circuitry.The response characteristics of the filter that supports feedback (resonance) and CV control of the cutoff frequency are 2-pole (12dB / Oct) mode, which allows self-oscillation, and 3-pole (18dB / 2dB /) with a switch on the front panel. You can also switch to Oct) mode.In addition, this unit has two audio inputs, one of which is equipped with an attenuator, so it is possible to mix the two input signals.
The Ivo input / output jack lights red for positive voltage and blue for negative voltage.The audio signal looks purple because the plus and minus alternate quickly.Inputs with attenuators are dotted with jacks and corresponding attenuator knobs. The I / O jacks on the Ivo are arranged from top to bottom as shown below.
The two cutoff inputs are added together.Similarly, the two audio inputs are added (mixed).In addition to the three attenuators, the controls include a cutoff frequency knob (blue) and a feedback (resonance) knob (yellow). The poles switch selects the filter response from 2-pole (2dB / Oct) and 3-pole (2dB / Oct).
