The Second Voice is a fully analog harmonizer using a phase-locked loop harmony circuit along with fuzz and a dedicated suboctave circuit to create synthy, glitchy, harmonically rich tones.
The Second Voice was Infanem's second product and has evolved quickly in only two years. The newest standard Second Voice retains the PLL harmony circuit of previous models and adds an additional analog suboctave circuit, tone controls, external sustain/gate control, and a CV/Exp input controlling the Range knob.
The Second Voice Deluxe also adds footswitches to individually mute/activate the harmony and suboctave and replaces the simple tone controls of the standard version with voltage controlled -12dB/oct active resonant low pass filters. CV/Exp controls are include for control of each filter's cutoff frequency.
