Behringer 173 QUAD GATE/MULTIPLES Quick Reference Cheatsheet

Overview

The Behringer 173 QUAD GATE/MULTIPLES is a utility Eurorack module combining four gate process channels and six sets of passive 4-way multiples. It’s a simple, but powerful, way to route and manage gate/trigger signals and distribute audio/CV across your modular.

Front Panel Controls & Connections

No Knobs, Buttons, Sliders, or Toggles — This module is patch-programmable only.

1. GATE Section (top 4 rows)

Four individual gate processors, labeled CH1–CH4.

GATE IN (3.5mm jack, left of each section)
Type: Input (accepts gate or trigger)
Input Impedance: 160kΩ, unbalanced
Voltage Range: Up to +17 dBu (~12V p-p, handle at least ±10V typical modular signals)
GATE CV (3.5mm jack, middle of each section)
Type: Control Voltage input
Impedance: >50kΩ, unbalanced
Non-Inverting (active high): gate opens with CV > +3V
Inverting (active low): gate opens with CV < +1.5V
Voltage Range: Up to 10V p-p
GATE OUT (3.5mm jack, right of each section)
Type: Output (passes gate if input and CV are high/truthy)
Output Impedance: 1kΩ, unbalanced
Voltage Range: Up to +17 dBu
Frequency Response: DC to 20 kHz
Output Noise: < -90 dBu

2. MULTIPLES Section (bottom 6 rows)

Six sets of four interconnected jacks per row (A, B, C, D).

MULTIPLES A/B/C/D (total 24x 3.5mm jacks)
Type: Passive parallel connections
How to use:
- Patch an input into A, and the signal appears at B, C, D
- You can also patch into B, C, or D — they are all parallel
Signal Types: Passes both audio and CV without clipping
Unbuffered (Passive): No active circuitry
No voltage drop unless you split to many loads

Voltage and Patch Notes

Works with logic, gates, triggers, audio, and CV signals.
Voltage thresholds:
CV Gate: > +3V triggers gate (non-inverting), < +1.5V triggers (inverting)
Max Input/Output: ~±10V (stated as +17 dBu)
Power draw: 40mA (+12V), 40mA (-12V)

Typical Usage Patterns

Gate Channel:
Patch a gate or trigger signal to GATE IN
Patch a control voltage to GATE CV to enable/disable passing the gate
Use GATE OUT to route the conditioned gate to other modules
Multiples:
Patch any signal (CV or audio) into 'A' (or any jack in the row), and break out to up to 3 other places

Reference Summary (All Jacks)

Label	Type	Function	Voltage Range
GATE IN	Input	Gate/trigger input	±10V typical
GATE OUT	Output	Gate/logic output	±10V typical
GATE CV	Input	Control of gate pass-through (internal logic)	0–10V (thresholds: +3V or +1.5V)
MULTIPLES A-D	Input/Output	Passive mults for CV and audio (any jack is input/output)	Modular levels (±10V)

No knobs, buttons, switches or sliders.
