Finally, a proper ABYss Box with a a ground lift and Phase Inverter function. Input on top right, Output A in center, and Output B at left (GND lift and Phase inverter are active only on output B).
With this ABY Signal Switcher, you can now use two amps without any ground loop and without worrying about phase matching. The signal of the output B is truly isolated from the input via a high quality audio transformer.
Left footswitch toggle between output A and B. Right footswitch activate both outputs.
Power consumption : 11mA
Voltage : 9Vdc center negative
