The Passive A/B Switch PCB 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.
- 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 batteryl
- Input jack 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.
- 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"
