MAS Soft Touch Relay Bypass Quick Start Manual

Soft Touch Relay Bypass
Typical 3PDT latching mechanical switches are noisy, hard to
press, and prone to mechanical failure after repeated use. A
controller board with a relay is a great alternative, and provides
some other really great options you couldn't otherwise do.
This tiny and featureful relay bypass board can do a LOT.
•
Soft touch, momentary switches can toggle your DIY
guitar pedal, using a relay to provide true bypass.
•
Quick tap to switch between engaged and bypass,
or hold the foot switch to temporarily toggle until you
release it
•
Fits easily in a tiny 1590A enclosure
•
Optional optocoupler muting can be enabled with a
switch or jumper to mute any popping your circuit might
exhibit while switching
•
Hold when powering on to toggle auto-on/auto-off
•
Passes signal when powered off

Usage Instructions

Engage / Bypass: When bypassed, the sound signal will go directly from your input to your output jacks. Tap
the foot switch to engage the effect and route the signal to your audio PCB. When engaged, tap the foot
switch again to switch to bypass.
Temporary Bypass/Engage: Holding the foot switch while the effect is engaged will temporarily bypass it,
and it will re-engage when you lift your foot. Similarly, holding the foot switch while bypassed will
temporarily engage it.
Auto-on: When you supply power to your pedal, it will either engage or bypass. If you want to toggle which
setting is enabled when powered up, hold the foot switch down while you plug in the power. The LED (if
used) will blink to indicate the auto-on setting was changed. If you unplug then power up your pedal again, it
should now start in your desired setting.
