Panel Reference

Inputs

PLS1 (Input)
Accepts: Audio or CV
Range: Typical Eurorack level (±5V / ±10V)
PLS2 (Input)
Accepts: Audio or CV
Range: Typical Eurorack level (±5V / ±10V)
BASE (Input)
Accepts: Audio or CV
Always mixed
Range: Typical Eurorack level
SW1 (Gate Input)
Accepts: Gate/Trig signals
HIGH = ≥ 5V, LOW = 0V
Normalized to 5V when unpatched
SW2 (Gate Input)
Accepts: Gate/Trig signals
HIGH = ≥ 5V, LOW = 0V
Normalized to SW1 when unpatched

Outputs

MIX (Output)
Unity-mixed sum of enabled inputs
Range: Follows input levels (expect unity gain, max ±10V)

Controls

SW1PL (Toggle Switch)
Sets gate polarity for PLS1
H (High): PLS1 mixed when SW1 gate is HIGH (≥5V)
L (Low): PLS1 mixed when SW1 gate is LOW (0V)
SW2PL (Toggle Switch)
Sets gate polarity for PLS2
H (High): PLS2 mixed when SW2 gate is HIGH (≥5V)
L (Low): PLS2 mixed when SW2 gate is LOW (0V)

Usage Overview

BASE input is always mixed/summed to the output.
PLS1 is mixed if:
SW1 gate is HIGH (≥5V) and SW1PL is in H
SW1 gate is LOW (0V) and SW1PL is in L
PLS2 is mixed under the same rules using SW2/SW2PL.
Manual Mute: With no gates patched to SW1/SW2, the SW1PL/SW2PL switches work as manual mute toggles.
Normalization:
SW1 normalled to 5V → PLS1 can be toggled manually if nothing patched.
SW2 normalled to SW1 → Both can be manually toggled or linked.

Application Tips

Pitch CV Mixing: High-precision summing means it's safe for pitch CV without drift.
Gate-Controlled Mutes: Use gate/CV sequencers for dynamic signal routing.
Audio Utility: Seamless for unity-gain audio muting and mixing.
Live Performance: Quick manual mutes via panel switches if no gate signals are inserted.
