Switching is silent and instantaneous. This is achieved by processor controlled long-life microswitches, while the actual footswitches serve as mechanical triggers only. Input and outputs are set to unity gain while output is lo-Z to prevent signal loss in FX chains and long cable runs.
Outputs 1 + 2 are floating and electrically isolated by a high quality transformer to eliminate ground loops. Since guitars need to be grounded for proper shielding output 3 is non-isolated.
When used to connect a battery powered tuner, output 1 can be grounded via a sliding switch. The discrete Class A FET input amplifier is similar to the input stage of a hi-Z tube amplifier.
Due to increased power consumption the 3-EASY is not battery operated, and as most pedal boards feature a 9V power supply, it comes without a wall wart. Palmer power supplies are available as accessories - the single output PW9V, or the universal pedal board power unit PWT12 with 6 x 2 isolated outputs.
