The Second Voice

The Second Voice by Infanem is a fully analog harmonizer featuring a phase- locked loop harmony circuit, along with fuzz and a dedicated suboctave circuit to create synthy, glitchy, and harmonically rich tones. The pedal has evolved quickly over the years and comes in standard and deluxe versions.

Key Features:
- The standard version features a PLL harmony circuit and an additional analog suboctave circuit, tone controls, external sustain/gate control, and a CV/Exp input controlling the Range knob.
- The deluxe version 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.
- Separate volume knobs for Suboctave, Harmony, Fuzz, and Clean signals provide complete control over blending and levels.
- Harmony selector switch allows for the selection of intervals such as one octave down, a perfect fifth shifted down one octave, a perfect fifth, an octave up, a perfect fifth shifted up one octave, and two octaves up.
- Gate control for sustaining the fuzz, harmony, and suboctave.
- Active -12dB/oct low pass filters with cutoff frequency and resonance controls (Second Voice Deluxe only).
- True bypass switching.
- Internal voltage doubling for increased headroom while using a standard power supply.
- Standard Second Voices have black graphics on a white 1590BB enclosure (4.7 x3.7 in), while Second Voice Deluxes have black graphics on a hand-polished 1790-sized enclosure (5.7x4.7 in).

Connections:
- Input, output, and power jacks located across the top of the enclosure.
- Uses standard 9VDC negative tip power. Current draw is approximately 100mA.
- Range CV (all models) and Freq CV (x3 on Deluxe models) accept either 0-5VDC CV or passive expression pedals.

Technical Details:
- The Second Voice is an original design developed and built in Portland, OR.
- Double-sided, through-hole plated PCBs produced in Mulino, OR and assembled in-house using the highest quality components.
