Switch 4

Joranalogue Audio Design

Performance signal switcher/router for Eurorack. Features four buffered inputs (normalised sequentially), a lower switching section with four dual-action toggle switches (latched up, momentary down), and an upper routing section with two rotary switches plus two dual-action toggle switches. Handles audio, CV, and gates/triggers.537

Capabilities 2

Signal Switchsignal-switch
Four buffered inputs with sequential normalisation; four toggle-switched outputs and two routed outputs allow manual switching and routing of any signal type (audio, CV, gate/trigger).537
Stereo Processingstereo-processing
Symmetric 4-switch layout handles stereo L/R pairs — route or mute both channels together.537

Jacks 10 — 4 in / 6 out

Parameters 8

NameTypeRangeBehavior
Rotary Switch 1switch1 – 4Selects one of the four input signals (A, B, C, or D) to route to Routing Output 1 via its paired toggle switch.537
Rotary Switch 2switch1 – 4Selects one of the four input signals (A, B, C, or D) to route to Routing Output 2 via its paired toggle switch.537
Routing Toggle Switch 1switchDual-action toggle switch for routing output 1. When active (up/down), passes the signal selected by Rotary Switch 1 to Routing Output 1; centre position interrupts the path.537
Routing Toggle Switch 2switchDual-action toggle switch for routing output 2. When active (up/down), passes the signal selected by Rotary Switch 2 to Routing Output 2; centre position interrupts the path.537
Toggle Switch AswitchDual-action: latched upwards (signal passes to output), momentary downwards (signal passes while held), centre position interrupts the signal path.537
Toggle Switch BswitchDual-action: latched upwards (signal passes to output), momentary downwards (signal passes while held), centre position interrupts the signal path.537
Toggle Switch CswitchDual-action: latched upwards (signal passes to output), momentary downwards (signal passes while held), centre position interrupts the signal path.537
Toggle Switch DswitchDual-action: latched upwards (signal passes to output), momentary downwards (signal passes while held), centre position interrupts the signal path.537

Firmware history 3 versions

VersionReleasedNotes
Rev DEliminated the possibility of glitches appearing on the routing outputs while turning the corresponding rotary switches.537
Rev CAdded +5 V normalisation on input A and output impedance compensation. Current draw increased from ±10 mA to ±25 mA.537
Rev BInitial release.537
