HS-115 - Deep Dive - 24db Low Pass Filter

Deep Dive is an analog, self-resonant low-pass filter with voltage control support. It features a 24dB slope and is based on a reproduction of the classic CEM3320 chip, used in many legendary synthesizers of the 1980s.

The cutoff frequency of the filter can be adjusted with the corresponding knob. You can input a modulation signal through the FREQ input. The modulation strength can be adjusted with the "FREQ MOD AMT" knob. The resonance can be changed with the "RESONANCE" knob and modulated by a signal at the "RES" input. The modulation strength can also be adjusted with the "RES MOD AMT" knob. The input level can be adjusted with the "IN VOLUME" knob. The filtered signal is available at the "OUT" output.

On the back, there are two trim potentiometers that can be used to further regulate the frequency modulation.
