DIY Passive A/B Switch

 

Features:

The DIY Passive A/B Switch Bare Bones Kit offers the DIYer a chance to build their very own stompbox A/B Switch to their own specifications. The input signal is routed to either Output A or Output B, with additional circuitry grounding the unused channel for superior noise-limiting performance.

Features:

  • All the wiring is on-board! Typical A/B switching configurations require tedious wiring; the DIY Passive A/B Switch PCB gets it done on-board so you can get back to making music.
  • Inputs and outputs are interchangeable: For example, switch two guitars/synths to a single amp, one guitar/synth to two amps.
  • Inputs and outputs are protected from switch pop noise by pull-down resistors.
  • 3PDT switch layout allows for stompbox switching and LED indicators gives you a visual cue which output is active. The DIY Passive A/B Switch circuit can also be used without power and still function.
  • Dual power supplies (9V Battery and +9VDC =>200mA Center Negative DC Adapter Power Supplies) allow you to have the battery as backup or as the main power. Tension-relief holes keep your power supply wires safe from being broken off by stage abuse or a loose battery
  • Input jack power switching – No instrument cable plugged in, no power used. Save life on your expensive batteries!
  • PCB ground plane reduced RF noise and other unwanted signals in your setup.
  • PCBs are professionally manufactured in the USA by Imagineering, based out of Elk Grove Village, IL, and designed here at Synthrotek. PCB silkscreen, through-hole components with careful on-board placement, and wire-tension relief holes were designed with the DIYer in mind!
  • PCB Dimensions: 1.625″ x 1.5″. Small enough for a rugged 1590B Hammond enclosure.
If ordering any assembled version PLEASE ALLOW 5-10 days of assembly prior to shipment
